Global LTE Bands? - Xiaomi Mi Mix 3 Questions & Answers

Hey all,
With the official global Mix 3 being out, is band 13 still only on the 8/256 model? I recently bought a 6t and am on VZW, but realize I should have just gotten the Mix3 as planned.

According to https://www.mi.com/global/mix3/specs/ it looks like band 13 is available on the 6/128gb global version now. Have the Mix devices worked on VZW historically though?

I used the Mix 2 on Verizon for almost a year. Worked fine... I even used the original Mix on Verizon. It would occasionally drop to 3g because it was missing one of the LTE bands but otherwise worked fine. Far as I know the mix 3 will work fine on Verizon as well.

Can't read it directly from my phone, but the mini manual thing that comes in the box lists these bands on the 6GB/128GB global model: 1/3/7/8/20/34/38/40 tho they could be wrong. I'd very much would like to read this info somehow directly from the phone, which bands it supports, but have yet to find that option.

That is what I saw on the website, which made me question it. Previously, band 13 was only available on the 8/256 and 10/256.

What model is your handset?

Never mind. Just saw it on XDA. Global version launched today, has band 13. Well. Time to sell this 6T

Verizon user here. I had a Mix 2s that was destroyed by a local repair shop dropping the logic board (took me a long time to figure that out) when they were replacing the screen. I should've just replaced the screen myself. I have a Mix 3 now (the 8/256 model) with the Global rom that was leaked a few weeks ago. Our organization has multiple in building repeaters as well as some smaller offices that have the "home" repeaters meant for < 5 users. My phone gets LTE coverage as expected everywhere and the signal levels are consistently BETTER than my Pixel 2 XL or my Pixel XL. They seem to be slightly better than the Pixel 3 XL I have. I think this phone is one of the best hardware packages you are going to get and the price can't be beat for the quality. Battery life was a minor concern, but the new OLED screen seems to make up for the fact it has a smaller battery than other similar devices. I've done several long distance road trips and had no issues with roaming or coverage. I've found one spot on a section of interstate near me where it drops to 1x, but the other phone I had dropped to no signal (Pixel 2 XL).
I did have to mess with the device to get the APNs setup. On the global rom it looks like you can just add one yourself. On the chinese rom, I had to mount /system as RW in TWRP and then overwrite the apns file to get a working APN for VZW MMS. ***I HAVE NOT TESTED THIS*** but I think you can just download the Messages+ app (which I kind of hate) and use it without fixing the MMS in the APNs. That is the Verizon app for texting. Using Messages+ allows me to send full quality pictures and GIFs that actually work as well as receive them. There is some kind of issue with the stock setup on MIUI that stops it from sending or receiving larger than 30KB MMS messages. This is documented all over and no one else I've found has posted a fix. If I have time I am planning on trying to see if there is a system setting that can be modified to fix that 30KB limitation, but the Messages+ app just bypasses it. If you have any questions feel free to ask here and I'll share/help.

Do you know the correct Verizon APN(s) to add (on global)? Or where I could find it? There seem to be multiple versions after a quick Google.

So here's the thing. If you use messages+ from Verizon, it ignores the missing MMSC. Everything else works by default so I just started using Messages+ since you can send and receive MMS and large gifs and stuff. I can give you ones that will work, but the other messaging apps limit you to 30kb MMS.

LTE Band 12, VoLTE, and T-Mobile

I am starting this thread, since there seems to be a lot of confusion around "newer" LTE bands, like Band 12 on T-Mobile, which apparently require a fully functioning and "approved" VoLTE phone to get reception.
There are various threads in device-specific forums, but they are not getting a lot of attention, and this is a significant enough problem that it should be more visible.
T-Mobile at this point has pretty fantastic coverage via the 700MHz Band 12 LTE network.
The only problem is that Band 12 requires the phone to be VoLTE "certified". The rumor was that phones could still connect to this band/LTE-network and send/receive data, but that they would fall back to alternative bands, even 3G or 2G, for phone calls. For a lot of people that would be "good enough" if not ideal.
Based on some recent testing, this is NOT CORRECT:
While phones may "sometimes" connect to Band 12 for data, the much more common scenario is apparently that the phone will disconnect from Band 12 almost immediately, or will refuse to connect to Band 12, and will instead default to an alternative LTE, 4G, 3G, or 2G connection.
In other words: even if you have perfect LTE Band 12 coverage (5/5 bars, or 100%), your "Band 12 capable" phone may instead try to connect to a really ****ty GPRS or EDGE tower that has barely any reception for the phone.
I recently encountered this with my Xperia X Compact while travelling: My phone would barely be able to connect to a T-Mobile tower with a GPRS data connection, while my wife's Moto G4 would get 5/5 or 100% LTE reception. Swapping SIM cards had the same result, so we know the problem rests with the phone.
Searching for "Available Mobile Networks" on my "band 12 capable" phone would show various T-Mobile 4G networks, but the phone would be unable to connect to them.
Talking to other Xperia X Compact owners, they have the same problem: the phone will sporadically connect to Band 12, but it is not a reliable connection (if the phone even connects) and it will (more likely) prefer other networks/bands/frequencies.
Based on the phone having the proper frequencies, I would assume that T-Mobile has some mechanism on some (or the majority of) towers where they disconnect non-VoLTE certified devices.
Anecdotally, I also had a similar issue with my previous phone - a Nexus 5x. The phone is even VoLTE certified, but when using Cyanogenmod/LineageOS, it would have really terrible reception, despite the location having almost perfect Band 12 coverage - LineageOS/CM does not (or had no) VoLTE support.
I have also tried "hacking" the X Compact to enable VoLTE support by adding the relevant lines to the build.prop and enabling the option under Settings and (*#*#4636#*#*) but this does not appear to make any difference.
A list of T-Mobile "VoLTE certified" phones can be found here:
http://www.spectrumgateway.com/compatible-phones
Would be great if anyone has any suggestions how to resolve this, or force the phone to prioritize Band 12, but it would otherwise appear that the only solution is to get the phone certified by T-Mobile (so much for net neutrality and open access).
I'm using an Xperia X Compact and my home market only has band 12 lte and I can't connect to it. Which means I'm always in 3g or roaming and rarely have data in buildings. It's maddening because I will only buy Sony. I think they are the only manufacturer making attractive handsets and the build quality is light years beyond well marketed, poorly constructed brands like Samsung and LG. But regardless of anyone's choice of manufacturer, a device with a functioning 700 mhz lte radio should function just fine on the corresponding network regardless of where it was purchased.
Would certifying this device and enabling VOLTE be particularly costly to Sony? Correct me if I'm wrong but based on internal components this device should be capable of this ja?
I think it wouldn't hurt to send petitions to both the manufacturer and T-mobile USA. This certainly doesn't help Sony in a market they are seriously struggling in. It also isn't very uncarrier to favor certain devices over others.
The only reason I switched from Verizon was the ability to choose my device. That and the things John Legere was doing to change the industry. I believed in what he was saying. But right now it isn't working for me and likely many others. He should know. I can say firsthand that the guy answers his emails. I think we need to show both parties that this is worth their attention.
---------- Post added at 01:09 AM ---------- Previous post was at 12:14 AM ----------
I should mention that after multiple calls to T-mobile tech support I received a cryptic call very late at night from someone high up in tech support.
Long story short he at least admitted that even though it wasn't a t mobile device and even though it didn't support VoLTE, it should still connect to band 12 just fine. He also said that they were having problems with this sort of thing in my area and that it should be resolved in a month. He also said my IMEI was logged and I would be given priority in the matter. Whatever that means.
I should also mention that was a month ago and he didn't have an email to give me. He did however give me a phone number (probably just the department) that I need to dig up.
Could just be a bunch of fluff because they are afraid to lose customers. Then again he was from tech support not customer retention. And as I said t mobile does listen to its customers.

Since I did encounter this also on my Nexus 5x with LineageOS, I doubt that what T-Mobile told you is true. They must be actively blocking these non-certified handsets, since the phone should just attempt connecting.
So who do we need to appeal to? T mobile or Sony.?

Both. Maybe also complain to the FCC - I thought that carriers needed to provide open access to their network. Verizon got into hot water for not doing so ...
Does your compact ever connect to lte for a few seconds after a reboot?
I might try to force LTE and restart and see if that has any effect.
I just flashed the UK. T mobile networks work just fine. Well except lte/4g but that was expected.

It does connect sometimes but it then usually kicks down to Band 4 or a GSM band (HSDPA, UMTS, EDGE, or even GPRS).
I cannot find any info how to prioritize LTE bands, so I assume this is T-Mobile's band 12 cell tower's kicking the phone off when they notice that it is not VoLTE approved.
Interesting discussion on Howard forums....

Interesting discussion though nothing new.
Yes, we know that Band 12 phones should be able to get a data connection, yet T-Mobile apparently actively disconnects them (or bars them from connecting), especially in areas where Band 12 would give you great coverage but there is no other coverage.
F Sony and F T-Mobile for this!
BTW: here is an article about the follow up model: https://arstechnica.com/gadgets/2017/08/sony-xperia-xz1-compact/
Please leave comments about Sony not getting their phones approved for VoLTE with T-Mobile and the phone therefore NOT REALLY WORKING with the carrier.
It would seem to me that the only solution to this problem would be either T-Mobile accepting a standard spec for VoLTE, they open source their code for VoLTE, or someone figures out how to implement VoLTE and trick T-Mobile to think it is an approved "whitelisted" phone.
Given that the T-Mobile network is getting worse and worse every day without Band 12 coverage, I find it really surprising that most people just don't seem to care. Does nobody use their phone outside of WiFi?

There is a standard spec, the problem is the certification. It requires a certificate from T-mobile to be used by the phone, which is gained through certification. And if SONY is detecting T-mobile at the modem level then there isn't anything a ROM can do with or without a ROM. I had a Z5, but this drove me crazy so I switched to a Pixel.
I wouldn't expect this to change based on SONY de-prioritizing the US phone market, so either upgrade to a new supported sony phone or move on (shrug)

That can't be true.
I accept that T-Mobile may issue a certificate but that must be processed on the rom/OS/phone.apk level. Otherwise, every custom ROM on any certified phone would work. We all know that is not the case.
If it's the rom/OS/phone.apk though, why can't we hack a phone to work with TMUS / VoLTE?
I have an x compact and while it is the best device I have ever owned it is essentially unusable on T-Mobile or att.

Because the SONY modem firmware doesn't even attempt to negotiate VoLTE, which does *not* happen in user space. It is likely possible to hack the qualcomm modem with QPST to enable this, but without documentation and correct values one will not get very far.

If it was the modem, then flashing a new system (eg custom ROM) should not make any difference.
I also have a Nexus 5x. With stock it is fantastic and uses VoLTE on T-Mobile. With LineageOS, it is useless on Band 12. SAME MODEM!
Experience therefore shows that it is the OS/System that somehow prevents this from working.

The Nexus 5x is a different phone made by a different manufacturer with a different firmware scheme. You cannot compare them directly.
I noticed that the XZ1 Compact says right on the website compatible with t mobile band 12 and wifi calling... this is infuriating. It should be easy for them to patch the Xperia x compact.
I would have never purchased this if I had known. Especially since they apparently flashed an update to my old t mobile z3 that allows voice over lte and band 12.

It has to be on Sony, use the t-mobile BYOD app to check, I have a Huawei mate 9 that I just purchased, connects perfectly on band 12, VoLTE works just like it's supposed to. On a side note I went through three Sony phones before I bought this Huawei, had to return all three due to quality control issues, one had worst touches that made the phone unusable, one wouldn't pick up the SIM card, and the third wouldn't power on at all, thank good Amazon refunded my money on all three. They may have the Sony name on the phone, but they are still build by the lowest bidder in China and makes with Sony's name.

See this: http://www.androidpolice.com/2015/0...cked-smartphones-and-yep-its-still-confusing/ It is up to an OEM to decide to go through this process per-phone. Since no US carrier carried the phone they didn't not bother spending the money or time to certify it. I loved the SONY design, but since they weren't supporting the market I had to abandon them for other phones.

[Global ROM] MMS and Verizon - Called Verizon Support, Still Broken

Hello all,
Phone: Mi Mix 2S
MIUI: Global 9.6.4 Stable
Model: M1803D5XA
Carrier(s): T-Mobile(SIM1) & Verizon(SIM2)
Issue: MMS receiving is limited to 30kb when using the stock Xiaomi and Android Messages messaging apps. APN settings do not show on device for Verizon SIM(doesn't matter if in Slot 1 or Slot 2).
So I called Verizon and worked with level 2 tech support to try and troubleshoot this issue. Basically, the MMS and/or Device server on Verizon's end cannot verify the device and therefore limits MMS sending to the device as it cannot authenticate. This verification is done by verifying the IMEI of the SIM and the device identification.
So basically level 2 tech support cannot verify the device manually and cannot submit a request to add the device information either, it has to come from the vendor(Xiaomi) to Verizon.
Anyway we can request this from Xiaomi going forward? Seems weird to have all the bands for Verizon, can get full 4G LTE coverage but I can't receive more than 30kb per image.
I had this issue at first. Flashed latest stable and it was fixed. It's fixed on miui 10 beta and its fixed on treble builds

Well I flashed to 9.6.4 stable, which I thought was the latest stable?
I'm flashing MIUI 10 right now...guess we'll see what happens.
*Edit, still not working on Verizon. And now on MIUI 10, Dual 4G is broken.
*Edit 2, now I have Dual 4G back. Verizon needs to be SIM 2, but be the default for Internet....
I'm on VZW only and I'm on the latest MIUI 10 beta. I'm experiencing this as well. My wife receives good quality images from my phone but when she sends from her Pixel XL to me they are terrible. As are images I receive from anyone else. Kind of a bummer.
Are you guys having issues getting connected on Verizon now? I'm not able to reliably connect at all, most of the time it just sits on 1xRTT on VOICE, and won't connect to data. I can get it to connect to LTE/VOLTE by smashing airplane mode or disabling radio over and over again. Occasionally it will go to LTE, but it doesn't stay working and drops out. I can't drive anywhere and even conduct a phone call as that doesn't stay up either. When it drops, it hard drops and acts like the modem is being reset, instead of roaming to a new cell tower.
Edit, forgot to mention, called VZW, they gave me the finger and tried to sell me an iPhone XS Max 512GB as a "suitable replacement" for my 8GB/256GB phone. They were not helpful, and told me that they have "teams taking steps to make uncertified phones not work on Verizon's network for security and safety reasons". I have tried two different sim cards as well, both with active service and both work in all 3 generations of Pixel XL that I have.
Why the hell would Verizon troubleshoot a phone they haven't certified for their network? Quit complaining.

Cause I pay them every month to provide me with service. They could've atleast escalated to someone with a brain and ability to look at logging on their side and tried to help. Your comment was not needed.
I have been struggling for days with my Verizon connected Mi Mix 2s. At times I could connect with VOLTE but I lost my MMS. This past weekend I tried various ROMs with no difference. I finally cleared everything, loaded TWRP and then flashed the Global developer beta.
I also put my SIM back into a phone that Verizon would recognize and reset the card.
When I was up and running again I did the *#*#86583#*#* to unlock VOLTE and then the 4636 dial to set LTE only. So far so good. I was then able to go back and add a correct apn for verizon. With Verizon Messaging app everything is working and stable, including MMS. Afraid to mees with it again. But it is possible to get the phone to work with Verizon.

Hi - is your SIM a newer (or brand new) SIM? I am seeing something in the logging on the radio logs that the SIM doesn't contain any carrier information, and was also seeing several errors about missing CMDA specific settings. This weekend I spent most of the day on Saturday and Sunday testing build.prop edits, and messing with the apns-conf.xml file settings. I could not get anything other than 1xRTT most of the time (I modified one of the existing entries in the list of APNs to be an exact match of what my Pixel 3 XL has) and by forcing LTE Only in *#*#INFO#*#* I was able to get LTE for brief periods of time, but not consistently. On 8.11.29 and 8.11.23 builds I can't get data working consistently, and if VOLTE isn't turned on, I can't get it to even act like it's going to connect LTE. I checked the APNs and played with it for hours, but not much success. The device just seems to "connect" but if you try to call on VOLTE or use LTE data to do something, the radio appears to reset. I am wondering if someone at Xiaomi neutered something in the RIL setup for their builds that broke CDMA compatibility. When I have time again, I will do some more comparison to see if I can figure out why it's not working. I'm planning on decompiling some of the files in question and looking at the code and configurations to see if something in there is the cause. The radio logs do not have a smoking gun. I also grabbed a copy of the build.prop file from MIUI9/Oreo and I am going to compare to see if they have some kind of prop flags that are missing in the MIUI 10 builds and or PIE builds.
I am going to find a way to make this phone work on Verizon.
Eventually, I rolled back to MIUI9 on Oreo (I don't know the build off the top of my head and the phone isn't near me) via fastboot. I have been able to get decent connectivity with that software version on Verizon where I live. I had to create my own APN, and have been using that with limited success. I submitted a bug report on the MIUI bug reports page. If you want to upvote that bug, the link is here: https://en.miui.com/thread-4724630-1-1.html
Edit: I just went to lunch and couldn't get the phone to connect to anything but 1xRTT the whole time we were at lunch (I didn't force LTE only, as I haven't had to previously since I rolled back). My next steps when I have time is to compare the build.prop between the builds, but I am not expecting to find anything. I am starting to suspect from the differences in the way the logging looks that they may have messed with the code or config information for the the RIL setup in the Android before they built it.
Please keep posting what you try, I'll be following with interest! I had everything working for a while but since MIUI 10.0.6.0 mms has broken.

Yeah, data and phone have been fine so far, I think a few times it's disconnected but messing with the APN has fixed it. In general, I'd say my data and phone have been pretty stable. MMS on the otherhand, I had working for a bit on 9.6. On 10.0.4.0 it's been really slow to send and receive or not working at all. When it did work, picture quality was awful.
PS, I have my phone set to Vietnam by mistake. I have an older SIM card, at least a few years.
PS still working fine.
Mine has been repaired, they had to resolder a connector for the antenna on the board and the logic board was dropped. I saw this happen, however, signal levels are as good if not better than the pixel devices in the same spots for me, so I don't think anything is permanently damaged. I've been debating trying to order another Mi Mix 2 from somewhere or ordering a Mi Mix 3. I have built roms and have a lot of android troubleshooting experience, and I can't seem to figure this one out. What I am seeing on my device is that once it is connected, it seems to not want to roam properly. Like disconnecting from one cell causes a modem reset and then it takes a long time to reconnect. I am going to keep working on it though.

So you had a hardware issue? After the fix, which things work and which don't work for you? When I disable VoLTE carrier check, I get the VoLTE symbol, but I can't make any calls. I've been messing with the SMSC, where it seems changes aren't persisting. I can't get mms to work anywhere but the stock app, which sucks because the stupid MIUI stock messaging app doesn't have group mms >.>
I had a screen break due to it falling on a very sharp corner of an object from about 6 inches up. I took it to a phone repair place locally. They dropped the logic board, camera, front facing camera/charging interface board as well from like 4 feet up onto concrete. The person who tried to repair the screen (which I provided the replacement for) did not follow the instructions on the video either and removed the plastic lining bezel from the phone body (you are supposed to remove the screen from the bezel with a heat gun). They had to send the phone out for micro-soldering to re-place and reattach the antenna connectors for the cellular and wifi antennas. They had to pay for that. I know what the phone looks like inside from watching the videos of how to replace the screen. When they gave the phone back, there was a substantial gap between the edge of the screen and the bezel in a couple spots (atleast 3 or 4 sheets of paper thickness). I ordered a new frame, bezel and screen all in one and replaced it myself (moved all the components from the original phone body to the new one). Everything appears to work, signal levels are good, but the cellular part will not stay connected, and the modem acts like it's resetting all the time. Sometimes it will stay connected to the repeater in the office I work in for 8 hours straight with no issues, and I can text and call. When I leave that area or go home, it doesn't seem to want to roam to service, and instead of switching cell sites it seems to just reset the modem. There is absolutely a possibility that some small transistor, resistor, cap or something else on this board got damaged when it fell. Given that you guys aren't reporting issues with your devices staying on the network, I'm starting to think I need to go back and make some serious noise at this repair place. I am no stranger to working on sensitive electronics, and I was extremely careful not to damage anything inside when I moved the components (and it was already exhibiting this behavior when I got it back from them before I took repairs into my own hands).
That said, I've spent the last two days trying to figure out if I can do anything that might be helpful with QPST and QXDM as well as playing with various additional build.prop configuration. Nothing there that seemed to help. Rolling back to MIUI9/Oreo seemed to help some but was not a magic bullet. I still had to manually configure APNs and find myself needing to reboot or airplane mode every time the device should roam to a new cell site. I am planning on trying to copy the "carrierconfig.apk" file that is part of the system settings off of a Pixel 3 XL onto the Android Pie MIUI10 beta to see if possibly Xiaomi has something jacked there, but since you guys aren't reporting issues, I am seriously starting to suspect that something is physically damaged after that drop on the logic board, but the intermittent behavior and the fact that the signal looks correct and normal when it's working is going to make it nearly impossible to identify the cause.
As a side note, there's a Mi Mix 3 on it's way from GearBest....

So on mine, I can't get it to connect whether VOLTE check is enabled or not. At the office I'm like 10 feet from a repeater, and it seems to connect on LTE/VOLTE (if that's toggled on) very quickly. I have VOLTE enabled on my Verizon account. On the extender, I can make calls on VOLTE, but can't call without VOLTE enabled. I can't get it to connect to VOLTE with the VOLTE carrier check enabled, I have to shut that off and manually toggle. I am noticing massive inconsistencies in the configuration information contained inside the carrierconfig.apk that is loaded in the system build by Xiaomi. I don't see a smoking gun there, but there's a metric crapton of differences.
If I am not next to this Verizon repeater, it usually takes multiple airplane mode cycles or reboots to get onto LTE, it just sits on 1xRTT forever, no texts or data come through when stuck in that mode. Any type of cellular roaming that should happen seems to just cause a radio reset, and it goes to blank bars with X and then it acts like it can't find a network to connect to for a while or goes 1xRTT with full bars and keeps resetting every 20-30 seconds.

How is Verizon supposed to support a device they aren't familiar with? This post comes off as whiney. Verizon does NOT have to support every phone capable of their bands, that isn't up to them. Way too many variables using an outside device. With that said, running the latest global beta with the sim card out of my Pixel I have zero issues running Verizon Wireless as primary and Google Fi sim as secondary. Both networks getting VoLTE.

I expect Verizon to use the standards defined for how these devices communicate. I expect Verizon to assist with troubleshooting by providing information and looking at logs as to what my device is doing on the network. This is not unreasonable. I am not asking them to tell me how to fix the problem on a device they don't support. I am not expecting them to just suddenly support a device, but I do expect them to be willing to look at logs and information on their side and provide feedback. I am glad to hear yours is working and am starting to suspect mine has some kind of hardware damage. The local repair place has refused to do anything to help out because "if it's got a signal, it's a software problem".

Well, if it worked before the repairs.. it is definitely a hardware issue.
Check your APN settings. I had the exact same issue with my phone, especially after the latest update. I called Verizon for the customer support and they couldn't figure out as well. Then, I pretty much looked at every settings on my phone and tried almost everything, only to have the issue fixed by modifying the APN settings. For some reason, after the update, the SIM card removed the custom APN settings that I added when I first purchased the phone. Instead, it had the CBS, FOTA, IMS, LTE - Verizon Internet APNs available with the APN set as the CBS (Sorry I'm not an expert, so I really don't know what exactly they are. I suspect that those were pre-saved on my SIM cards as I have used the same one for 3-4 different phones?). Anyway, I googled Mi Mix 2s Verizon APN and set it according to the very first result I found. Since then, the MMS has started working well again. Hope it helps.

Note 10+ - Horrible signal strength

I received the Blue Note10+ from the Samsung preorder. (SM-N975U1). I'm using it on T-Mobile.
I'm having serious signal strength issues. My Note 8 is at 3 bars while the Note10+ has 0 or 1 bar while indoors. I usually have full 4 bars with the Note8 when I walk outside, but I rarely hit 3 bars with the Note 10+ wherever I'm at. I've never hit the full 4 bars yet with the Note 10+.
Is anyone having this issue? Any suggestions for a solution?
Bars alone don't tell the whole picture as each phone is calibrated differently. The only way to know for sure is running speed tests and comparing actual signal strength numbers in the settings.

Get the actual signal strength on each phone to compare...I have a TMO version of the S10+ and unlocked versions of the Note, the 10+ and a 9... the db strength measures the same on all phones, yet the TMO version shows additional bars... for example, at 99db to 104db, the tmo shows 3-4 bars, the unlocked 2...
Go to About phone, Status, sim card status to get the actual signal strength...
Same. Pixel 3 works, Note 10 has zero bars and doesn't work. I assume it's not connecting to TMobile bands
I'm on Sprint, got the Note 10+ around 9:30 yesterday. No issues whatsoever.
Can you tell us the dbm compared to the pixel? I'm really curious if I should just flash the tmo firmware before I even bother to load it.

Did you check for software update when you got your phone? When I received my unlocked Note 10 on the 21st, there was a new software update. Although the update didn't call out signal strength specifically, but you never know... After playing around with the device, I flashed it with T-Mobile firmware. I didn't have enough time to test cell signal, but haven't seen issues yesterday and today. The signal strength is on par with my Pixel 2 and S10e
I've run speed test at the same exact spot with my Note 8, OnePlus 6T and Note 10+ and they're all just about the same, between 85-90Mbps DL.
I have one less bar at home but still managed to get 120mb download speed. Havent looked at the dbm readings. Elsewhere its been just as good as my s8+.
Unlocked N10+.

I am on Tmobile and also bought the unlocked (note+) version and ran the update. If you could be so kind, what does flashing the Tmo firmware do (and how do I do it)? Would this give me everything Tmobile puts on their phones? Is there a benefit to doing that? I am curious if that would help with the signal strength.

You just use Odin to flash TMobile firmware for note 10, you will have all TMobile bloatwares and features that built-in T-Mobile firmware. I believe you gain more signal bars. I also think you will be able to do video calling on your U1. I don't have note 10, still hang on with my note 9, N960U1.

So if you flash T-Mobile firmware on your Note 10, you will gain few features:
1) Advanced Messaging - be able to see when person read your sms, when it was delivered or when person is typing a message. You can also send images/videos of a larger sizes about ~10MB. This will only work when you text people that have similar software or that use T-Mobile
2) Video calling will be built in to the phone dialer app - works with phones from T-Mobile that use similar software(LG, Samsung, Moto)
3) Will have 4G LTE wording in the status bar instead of just LTE or LTE+
4) T-Mobile logo on boot and sounds
5) Practically no bloatware - after flashing, during phone setup, you will be asked if you want to install 3 T-Mobile apps: Visual Voice mail, T-Mobile account app and Macfee antivirus - just don't check boxes if you don't need them.
The reason I flash my phones with T-Mobile firmware is that, before releasing they test the update so it would work better on their network and that I have T-Mobile

AWESOME! Thanks for the reply.
I have noticed something about my signal. It may show one bar but compared to my Note 9, so far, it is blowing it out of the water with internet access. The building I work in has a metal roof and typically that spells trouble for fast browsing. The 10+ seems to be accessing sites faster. However using the GPS this morning I could have sworn it told me it lost signal.
*edit*
Forgot to ask...when flashing the T-Mobile firmware does that trip Knox? Is that still a thing worth worrying about?
I haave two conflicting opinions on flashing tmo firmware.
Thing One.
The carriers lie to us. That's why the tmo signal is better. Not because it's better, it's probably a marketing directive. Resetting the Calc of bars shown to dbm is not optimizing anything. It's making its customers not see dead zones and drop outs. Even though you still have no access on the device.
Thing Two.
But what if I'm wrong. Is it impacting my battery life having computationally lower bars?
Oh the madness.

I have zero bars now on N10 with T-Mobile band 66. Unfortunately I have no clue how to check bands on Pixel 3 phone, it gives be 4 bars of LTE
I have the same crap signal strength. My note 4 and 9 no probs. Changed sim card. Changed carrier, took phone To an authorized Samsung service center same problem. I find on Google that and saw how many others are having the exact same problem. The Samsung service center said they've been getting more and more calls on this problem and it's not a software issue it's a hardware issue. They told me there's not a hardware update, meaning there is not an antenna that can be replaced it's Built-in to the phone to where they couldn' change it out
flashprash65 : So are you telling us that we will never have a better signal than we currently have?
That we spent $ 1200 for a product that will never work properly?

Yall have these Verizon OnePlus 8 issues?

Is anyone else getting freezing using chrome browser? If so what browser do you recommend? I've tried Firefox to and Opera for some reason this phone hates. I don't get why this phone is so slow. Mine takes a minute to process anything. Really hope they fix these software hickups. I guess FR but that would be a big job. The battery consumption seems to be the only best feature on this phone.
Yes, seems like it's a OnePlus problem. No one has a solution that I've seen yet.
I just minimize Chrome and reopen it and it works again.

It's not just on this phone. I just came from the Essential phone and Chrome's been doing that for months. It's Chrome, not the phone. I don't think the built in webview is playing nice with the os. Maybe try Chrome beta?

Nice. Glad I came across this noticed it instantly when I first got this phone back in April course I couldn't find anything about it then. And oddly it seems like it is way worse and 90htz. Was about to return too vzw. Honestly was thinking it may be a device issue Till I read posts Any suggestions? Gonna try brave
Not really sure where to ask this question but Verizon OnePlus 8 UW. No root or anything outta the norm. Constantly having intermittent data loss, intermittent hotspot loss, calls and texts as well I'm sure since they pushed an update couple weeks back. Message I get from there network troubleshooter says( Your phone can't auto switch too a faster network if it's available. Your better off too use Cdma/Lte or global mode for better signal strength). Far as I know Cdma had been reserved for EMT/Fire etc. Problem seems too arise only when the silly 5g icon comes up. So thinking when it tries too switch too 5g its having that intermittent loss going back to global mode an getting hung up somehow as a simple restart fixes it temporarily. If I was rooted I believe a prl or apn change would fix it maybe. So tired of dealing with Verizon techs, Any help it fix would be great

Sorry ta hear I've done a lot of searching and can't seem to resolve it. Dealing with Verizon it's just getting so old I believe I'm going to just try an root, flash, etc. That or go T-Mobile. If I may ask are you in the States? I'm in Florida btw. Very populated city Clearwater is a big fact and it's a problem all around
I've had Verizon family plan for 20 years now. So I have to deal with it. I remember buying old Galaxy s3 and moding the hell out of it. But I'm older and don't have time like I did when I was younger so I'm stuck. The problems on my OP8 5G UW just accelerated. I'm pretty sure it's software related. Last system update was a "network improvements" haha- yeah right! Since after I've been in hours and hours in Verizon chats, calls, I've spoke to OnePlus techs, I've done replacements, sim swaps, clean resets. Nothing is working to resolve my 1mbps download speed network is slow as hell, 17 Meg's 20 min. Tomorrow I'm talking Verizon tech to get my 4th replacement turned in and hopefully get a Galaxy S10 FE. I always wanted ONEPLUS but not this way. I'm done

I'm in Frederic Michigan, near Grayling. Rural area, but Verizon is king up here. And, with a low population density, I've had really great service for years. Up until recently. Wife has a Galaxy Note 9 and doesn't have half the issues.
So update. I wasn't allowed to move on to another phone with old big red. I exhausted my replacements with Verizon my only option now is to pay this off and move on. I did get some slight improvements turning the automatic to manual in Network Mode. It seems like I don't have the constant 5g/4g fight. As for original topic, I use the Samsung browser and I don't have any hanging or freezing.
Yea I'm kinda and the same boat got a phone didn't work good paid it off early got the OnePlus and now this I did switch to manual too and it helped a little bit. But not a lot we can do I definitely won't be buying any more Vzw phones. I can't even maintain consistent hotspot for over 30 40 minutes ever since past update. I have the 5G icon now that's not really 5G speed at all. I've gotten true 5G on this phone a couple times and it's amazingly fast. The 5G icon fades an drops too 4g when it does it kicks me off discos hotspot an network sometimes. I just don't have the will to deal with tier 3 tech anymore lol. I had prepaid for seven years with Verizon and it worked flawless many different phones over the years soon as I got postpaid went to hell

I'm in New Orleans and delt with all Network connection problems too. I'm on my 3 rd replacement and spent hours, days, and weeks ping-ponging through Verizon finest bull**** techs, Verizon sent me to OnePlus tech where the tech there referred me CDMA LESS and after a long work about found out that I was already on CDMA LESS. The only thing that helped other than bazilion factory resets and it's not the solution by any means is turn the automatic best Network set it to manual Verizon 4g. You still get the stupid 5g emblem but I've noticed an improvement as in connectivity. Not stable, I get interference and dropped calls all the time. Also i read something on how Verizon used cheaper antennas for their fake 5g push. Also could this be a conflict with Oxygen? I'm reading a lot of similar Network issues after updates.
Right on thanks, Not sure if manual mode actually sticks. Does it just switch back? But yes I too figured it'd help out. When I do let's say Run a diagnostic from Verizon's app one of the first things it says is this phone cannot auto connect to use lte/cdma for better signal. And that's wild it's connected and automatic mode. So it's obvious it's a hardware issue or software issue on their end. If they would allow you to control the phone we could fix it. Just got my first replacement today. Fixing the boot it up soon and see what the deal is software wise etc etc. The connectivity issue were both having is just 1 issue lol. I've got six or eight more easy. Mine seems like it's good data connection wise either with the fake 5g icon or without it. Bars will start fluctuating pretty rapidly (It's searching) I'll lose the 5G icon in turn lose hotspot lose date connection etc. Then it will come back with no 5G icon, connect, Be gr8 for about 10min or I reset prl & net setting. Someone tell me there 5g for most parts like here & there is basically just a glorified 4G LTE. There 5g coverage map clearly says or did there's no 5g here. I believe this to be true as I have connected to real vzw 5g in Tampa an you can tell big time!! This 5g even with there signal booster they sent me is not any if all better than 4g. Could kinda care less about the 5g it's the consistent intermittent network issues. Pls lmk what you find out either by p.m. or what have ya. I'll do the same. I'm gonna try this new vzw root I believe an switch too global or whatever I need too do weather it voids certain things or not lol. Sorry 4 the long read but wanted give ya what I knew. Here's a shot of there diagnostic mess. From vzw. An a shot of real 5g speed test before the updated deal that displays the 5g icon

Correct radios/network for UK 02 / Giffgaff

Hi there,
Got a transparent M10 Ultra from Wanda Mobile a few weeks ago. It come with a screen protector already applied (not sure if this comes in the box as standard?) and had Google Play preinstalled (though if I had realised I would have asked for a sealed box...). Anyway, after the week of waiting, unlocked and flashed stable Xiaomi.eu ROM and updated to latest (12.0.14) at the weekend. When I was out and about though I noticed that I rarely had 4G on GiffGaff (02) and dug into the settings.
My SIM is in slot 2 and the 'Phone information 2' showed 'unknown' for 'Set Preferred Network Type'. Popping the SIM back into my trusty Poco F1 it showed it as 'LTE/TD-SCDMA/UMTS', and I have now changed the Ultras settings to this. However, when I went back into this earlier it had gone back to 'Unknown'.....
If anyone could help with their settings it would be much appreciated. Any comments on Wanda Mobile also welcome...
Cheers,
Mark
The phone has no band 20. O2 and carriers that use O2 like sky and gifgaf use band 20 for 4G, so sorry any mast that uses band 20, you're on 3G or 5G. Some local area masts for O2 do use other bands for 4G but most are on it. Three, Voda and EE are fine.
I've had my ultra since launch and to be honest as everyone is using 4G and not 3G, the 3G data throughput I get is superb, so not really missing it. My second sim is EE for work, 4G is not an issue.
My advice, put it in SIM 1 use default settings.
Ahhh. Many thanks that, and for many of the other posts you have made here which have helped me out no end. So now I need to look for an alternative to GiffGaff (which has been great as I work offshore, so only need data every other month....).
Seems I must be super unlucky to have picked the Ultra then (and my previous Poco F1 does has band 20...)! But so far finding it a great phone. I thought I saw you post somewhere about loading up the Chinese camera version, but cannot seem to find that post now....
No, not me with the China camera I'm afraid. The EU ROM uses the same camera app as stock, a different app would just not be practical to make when the EU ROMs are all based on the stock released versions. So if there are any changes in the stock app, it will be the same in the EU app. You can download the Gcam downloader from playstore and it links to a Xiaomi friendly gcam version.
I know EE works fine for sure on the Ultra as I've got it in SIM 2, no problems with 4G as it doesn't use band 20 for its 4G, if it helps. I'm sure there must a a cheap offer for someone using EEs infrastructure.
Not sure where I got that info then, but what you say makes sense. That said, I'm still bemused why there is the 108MP option in the stock app (and what does it do if you click it...). I installed the Nikita GCam and XML, but unusually am not seeing any great uplift from what I am taking. However, I would like to totally disable any beautify in the stock app, but not found a way to do that yet...
I found EE Flex which has the ability to pause the plan, but nothing else so far that compares to GiffGaff as in only paying for a single months bundle....
I did see 1pmobile on EE, but think that could get expensive on data...

Although 1pmobile uses the EE network, 4G speed is capped at 20 mb/s so you should bear this in mind. The other option on PAYG is Asda mobile which also piggy backs off EE network.
A cost effective option is to use an EE preloaded 24gb data sim which lasts for a year as a second sim for the times you can't get a decent signal with your other sim.
I use Three network and have had no issues in my area (NE UK) getting 4G+ (50 mb/s) and occasionally can get 5G (180 mb/s download speed)
It doesn't look like you can get the EE preloaded 24gb data now... when I search and click, it takes me to a page where they now offer 30 & 90 day data sims... Asda Mobile looks promising though as an alternative to GiffGaff. Certainly looks like it is a true 30 day bundle (and not a reoccurring one)...
