Xperia Z5 ATT&T Signal Bars Fluctuating - Xperia Z5 Q&A, Help & Troubleshooting

Just got the phone brand new factory unlocked. So i upgraded to 6.0 and all the Sony updates. I have tried setting the band to HSPA and LTE only. Nothing seemed to help.
My Signal is -96-100 dBm 44 asu at home, other places i am at like -113. See lots of HSPA and 4G has one or two bars tops.
I know i am not the only one with this problem. Any ideas? I registered my IMEI with AT&T. Running out of ideas, i mean its usable but i tried hotspot and wasn't able to stream movies at my friends house. .. Really like this phone, don't want to get rid of it.

I'm in Ireland and my signal is gone completely in the house and good 4g+ full bar in some area, once drive out of big town or city my signal drop to H and then no service very quickly, that happened a week after upgrade and unlocked bootloader, same network same sim since December. now no matter what network sim, all the same
I no longer use the phone and I be getting another z5 replacement but I am going to sell it brand new in the box and get a HTC dual sim, not taking another chance with it

Don't worry about it, the phone doesn't have the dbm levels set for US carriers. See this on T-mobile but consistently have a high speed LTE connection that doesn't drop.
Just a visual bug

that's what i was hoping for. is there somewhere i can edit to match up the visuals so it looks better ? prob not without root.

I'm not, I'm in Ireland, no AT&T here, but all network sim does the same thing in my Z5, but all sims work fine in other phones, have a brand new green Z5 sealed in box think I'm just going to sell it. afraid to do anything with it after the bad experience

Been using mine here for some time now and it's the graphical icon issue. Signal has been great. I have all the updates done.

Would be interested to find out if this is true, I think this is set in the radio though, so maybe somewhere in the qualcomm nvram ram?

on the Z5 thats not working, it is literally not working, when try to make a call it says no mobile network, and data doesn't work, but with the new Z5 I got, I have the opposite, signal shows full bar on H+, but its at -83 db so thats no full signal, but when its on 4G it seems accurate, they are both Rev 1
I hope I find out what is wrong with the other Z5, I had opened it and inspected everything, it all looked perfect, I'm hoping it is a software issue but I've no way of testing anything

Droid 2 Global with 3G on Rogers

Here it is. Get a unlock code and it works on Rogers network, with 3G.
Just remember to set APN first.
So it is confirmed that Verizon is not messing up the 850/1900 bands outside US.
Canadian Droid lovers, you are safe.
Btw, this phone seems to have some serious reception issues. It only shows one signal bar in my house, while other phones would get full. Hope moto could fix this via a software update.

Thanks for confirming this for us. We hear in the US are still having those problems with AT&T and T-Mobile. Hopefully we will find a workaround soon.
Thanks so much. Thats what I've been searching for. BTW, where did you get the phone? Can you just go to Verizon store and buy it outright without signing any contract, not even the month by month plan?
Got the phone from a friend in the US. What he did was activate a month to month plan, and cancel it right away.
where did you get your unlock code? can you recommend a site?

Got it on ebay. Just search for "Dorid 2 Global Unlock" and there you go.
I am following yous steps! I already asked a friend of mine to get me one. Thanks for confirming it is good on Rogers. Ebay seller is a bit greedy though - 50 bucks - ouch!

Byebyebryan, how is the battery life on Rogers (I assume you switched it to GSM/WCDMA only)? People report some horrible results like 7 hours with no use.. can't be that bad...

Why would you have to pay for an Unlock Code? Can't you just "ROOT" the phone free?

The unlock code is so you can use non-Verizon (Vodafone) SIMs. Rooting is being able to have full read / write access to the entire phone. Rooting alone will not unlock the radio to use 3rd party SIMs.

Has anyone else noticed reception issues with this phone? I was waiting and waiting and waiting for the Milestone 2 originally and then this one came out and I want it sooooo bad. I need to upgrade from this HTC Magic but I don't want to buy a phone with hardware flaws.
I tried Googling it but all I'm finding is reception problems on the Droid 2 and the Droid X. Not a lot on the D2G but it seems like the entire Droid line has people reporting reception problems.
Is it just the number of bars showing thats a problem or do you also get frequent dropped calls?
I heard from a friend that Android 2.2 includes a new Battery Manager that reduces power to the radio when you're not making or receiving a call and that's probably why the number of bars showing is low when the phone is idle and there probably isn't really a reception problem unless calls are being dropped. Can anyone confirm this?
It's a long drive from where I am in Canada to the nearest Verizon store so I was going to make purchasing it part of a road trip to visit friends in Seattle in a couple weeks if I can get confirmation that the reception problem is not hardware related.
Any confirmations or advise would be greatly appreciated.
Thanks
Reception hasn't really been an issue for me. Seems acceptable. Battery life marginal though but I had the same issue with an HTC Desire

The funny thing is, even though the phone is showing only one signal bar, I still have great call quality and 3g speed. Wired.

Thanks guys. That was the news I was hoping to hear.
I was having problems with the 3G in France. I never got more than one bar and that was in middle of Paris
Buy it on prepaid. Its $394 plus $104 of other stuff, total 537.

I just got the Droid 2 Global and have it unlocked on the Rogers network. I can't get the 3g to work. What APN settings are you using or how did you get it to work? I have input the apn settings that are being posted around the web but can't get 3g to work. Edge works however. Thanks for your help.

APN settings are same for 3G and EDGE. Are you sure you are not forcing EDGE somewhere in settings? Or maybe battery manager?
I figured out the problem. I had the phone in "gsm only" mode. When I switched back to"Global" mode in network settings I instantly got 3g and even "H". Thanks for the help anyway

[Q] Signalstrength and mobile internet connection issues

I often have issues with my signal being at 1 or 2 bars where friends of mine (Galaxy S3 and iPhone 4, but same operator) have like 4 or 5 bars. Sometimes people cant even call me even though my phone shows 1 bar of signal.
Buts thats not the worst thing. My mobile internet connection seems to not work EVERYTIME I'm in some kind of tunnel, sometimes even in normal houses. It shows that it tries to get information (arrow up and down) but it doesn't (it even switches from H to 3G, which doesnt even make sense). In the end it tells me the networks not working.
Does anybody have similar issues?
Some boost mobile user reported similar behaviour.
I've flashed the ICS radio and signal is much stronger. While running the jb update I would have full bars and still get 'bad connection please turn on WiFi to connect to the internet' 4g full signal would do the same thing. Until I flashed ICS radio of course.
---------- Post added at 10:05 AM ---------- Previous post was at 09:58 AM ----------
Edit. Probably the network, looks like jb radio is the same one, weird though my signal is much stronger now. Must have been a placebo, + the network being 'optimized'
Edit. Can any one verify the boost mobile jb radio? 'its the number under settings next to baseband'
Mine is 1.12.50.0516

I just got my replacement phone. Let's see if this One SV has the same problems. If so, I'll tell them to give me a different phone, I can't use it like that. I'll tell you guys.
I got a new one. It's a non LTE though. But it works way better now. Driving through tunnels makes my mobile Internet disconnect for a second now, but I guess that's pretty normal. Before it didn't work at all in tunnels. Maybe it had to do something with the LTE variant.
Gotta check if the phone signal got stronger too.
By the way I'm writing this while being in the subway station.

My LTE SV has roughly the same reception as my old phone, the Desire, which has always had great reception for me. So in your case it must have been either a defective terminal or maybe some weird software issue.
It's a shame, though, that they've replaced your SV with a non-LTE one. You did pay for the LTE version, that's what they should've replaced it with.
Well, something is still not right with this phone. Even though my mobile internet is working as intended now, I still have big connection issues. Sometimes (at least 5-10 per week) I lose my signal completely, which shouldn't be too much of a problem if it lasted for like 10 seconds or so, but it doesn't reconnect on its own. I have to restart my phone every time. People often can't call me for hours because I don't notice that it lost its signal once again.
I will call them and tell them I want a different phone as I'm still paying for it. I can't use this one anymore or at least not for my job.

Well, now that's weird. I mean OK, you might get one bad terminal, but to have it replaced and still have the same issues...?
It might be that your radio/ROM isn't compatible with the network, or maybe you have a bad SIM card. Try and replace the SIM, see what happens.
I live in a bad signal area. I usually get 1-2/5 bars on WCDMA and 3-4/5 GSM bars. Sometimes when the phone switches connections it'll take 2-5 seconds to do so, but i've never had it remain offline etc.
Could you please tell us where you're from/what operator you're subscribed to?

I'm from germany and my operator is o2. I contacted them again. They told me they can only send me another replacement phone, which wont change anything for sure.
My problem really isnt that it doesnt have signal for a short time period. My problem is that it stays like that for hours!
Please stop quoting the post you're answering to if said post is right above yours. It clutters up the forum.
Right then. So ask for a LTE replacement - that's what you've paid for, that's what they should give you, and see if the problem persists. If it does, use the phone without an SD card for a few days, try not to install any „toggle” software (like 2g/3g toggle widgets etc.) and replace your SIM card (it should either be free or cost you some 2 EUR - that's what Vodafone charges here in RO). If the problem still persists, it must be a network issue.
If you have a few minutes, try this: Settings -> Mobile Data -> Network Operators -> Search Networks, give the phone a few minutes to look for networks, then when it displays the network list, tap on yours and allow it to register. See if this changes anything.
Sorry sir. I'm just pressing that reply button. Didn't know about the one under it.
I just found out something pretty retarded. I went for the network settings and chose the network mode "GSM/WCDMA" instead of "GSM/WCDMA/LTE" and it instantly jumped to 5 bars from 1. It's the fricking LTE network.
By the way i made a mistake. it was a LTE version replacement from the beginning.
Yupp, thats what i always do: let the phone always work in the best available network (set by me to GSM Only).
This Network is pretty stable at my place and its also battery saving because it don't search/switch for another net.
Well that's quite crappy though. I didn't buy a LTE phone and a contract that allows me to use it, just to find out that it doesnt work as intended.
God I hate it.
I told them that this is the problem and they're just sending me a new sim card. Don't really expect this to help, but let' try out and afterwards I'll just contact them again.
At least the phones stable now...
Well, it's not the phone's fault. It's the operator's fault. Their LTE network is not developed enough. You should be happy, though. Vodafone Romania does advertise LTE, but the coverage is somewhere near 0.01% of the country (mostly near Vodafone shops or by the seaside). So where i live i don't even get LTE. And i live in the capitol. :laugh:
Thats what i think. LTE is far away from stable and everywhere available.
Near to me is a village, where you can't use a mobile phone, because there is NO network at all, lol.
What?! In DE? I thought that only happened in the East!
Yupp, in the middle of "DE"...
Lol, don't wanna live in this village. Many jokes and so, you can imagine

russellvone, you're lucky.
In the area I'm in a bunch of Boost customers had serious signal strength issues starting last week, and data feels like it's been throttled to 2g/EDGE while we all get "4G" on our status bars.
Service feels like it's been declining, and I've only been with them since June of this year.
PRL updates did nothing.
I used Tmobile prepaid for my personal phone since the Nexus S launched, then a Galaxy Nexus.
The only reason why I didn't get a Nexus 4 was that I thought I was missing out on something without LTE.
I got the SV for free, so I didn't exactly choose Boost.
I just needed something to hold me over a few months.
Now, I won't care if the Nexus 5 has LTE or not, I'm buying one and going back to Tmo.
The SV is fine, the service.....that makes it or breaks it for me.

Shield LTE on T-Mobile issue.

Just got my Shield LTE today. This is my first tablet ever as well as my first unlocked device ever so I've never really had to mess with APN settings before. Long story short, I can connect and get HSPA+ ok but the speeds suck and no LTE at all. My Galaxy S5 can pick up LTE fine and get around 50Mbps down, but the Shield gets only about 5 down on HSPA+. When I search for network operators, my only choices are T-Mobile (2G/3G) and AT&T (2G/3G/4G). Any ideas as to why it can't find T-Mobile LTE network?
Does your phone work with LTE in the same spot? I got my tablet yesterday and moved the TMO SIM from by iPad to the Shield. Got LTE right away without doing anything with APNs. Depending on where you are, TMO LTE coverage is spotty.
Yes. My Galaxy S5 gets about 3 bars on LTE while sitting right next to my tablet that only has 2 bars on 3G. Just got off the phone with T-Mobile and they said they could see me connect to the LTE network and I did see LTE come up on the Shield for a moment but then it almost immediately dropped back HSPA+. I think its an issue with the tablet itself. I'm on hold with Nvidia now.
I'm still trying to get my Shield LTE activated on T-Mobile for the 200 MB free data for life deal. T-Mobile told me that their system saw the Shield's IMEI as a phone, not a tablet, and to bring it into a store so they can see that it is indeed a tablet.
The APN Settings came down by default for me and appeared correct with what I've searched online, but I'm having the same issue where I'm not getting LTE here in the PHX market, in all the places my phone gets full healthy LTE.
I don't want to complain about my H+ signal, but it's just not cutting the mustard if you will.
You find/hear anything useful here Hoju?
I'm seeing the same issue With LTE/Tmobile alsnly HSPA+
I've been in contact with Nvidia support since last week and they have had me send them numorous diagnostic files and bug reports. From what I can tell, the Shield is using NVIDIA
's Icera i500 modem which can be thoroughly tweaked through software updates. I'm hoping this issue can be resolved with such an update. Nvidia level 2 support told me that I was the first case of this reported, so I urge everyone suffering from this issue to contact support so they can see that the problem is not an isolated incident. I'm hoping to hear back from them today regarding this. I will update the thread when I do.
T-Mobile setup my imei number as an iPad to activate sim and didn't give me the pin, called T-Mobile and got it fixed, the pin turned out to be 1234, once he fixed the imei and changed pin, internet started working well and LTE is working as well. Also logged into T-Mobile.com/connectme I'm not sure if that's required but that's where you can buy more data. Hope that helps someone
Hi there, T-Mobile retail dealer here. I've tried 4 different T-Mobile sim cards (2 $50 simple choice plans, 2 $70 simple choice plans) along with 4 of their MVNO's sim cards (Univision Mobile, Straight Talk, Ultra Mobile, Lyca Mobile) and they all had LTE.
With all of the T-Mobile sim cards, the standard APN that's loaded in (fast.t-mobile.com) works perfectly for me.
For the MVNOs, using their respective APNs allowed for LTE, while using "fast.t-mobile.com" on those services only gave me HSPA+
I'm also located right outside of Philadelphia. Not really a populous area but we have good coverage with T-Mobile around here.
Hope this helped.
I also just added ro.ril.fast.dormancy.rule=0 to my build.prop, result so far is stable connection on h+. Without that it was flipping between 3g and h+ constantly and connection was unstable. ive been streaming music and it did change back to 3g, but not back and fourth like before, ill keep an eye on it.
maybe i spoke to soon, i still see it switching. Ill update after some more testing if this did anything or not for me.

Not really, guess it was a placebo effect at first and just happened to stay on h+ for a while. from what i have read over the last few days is that on t-mobile's network it switches to 3g to save battery. I just removed the line i added, streaming music right now and just got a drop out. If someone knows or comes up with a way to force it on h+ I would happy, i could care less about battery savings if i just have this thing on my desk plugged in all day.
I got some time today, going to try staying off of wifi all day and see how it acts, might try a couple things if i can find some other options to test. if i find something ill let ya know.

Thanks for the response. I ended up exchanging mine with a new one that I just received last night. Right now I'm still testing and hopeful it will shape up, mine would drop from H+ to Edge, I do get LTE from time to time but it's very sparse. So far the replacement is doing well but i'm more and more convinced this is a radio issue as the tablet was really certified on AT&T. I've filed a ticket on my old one with Nvidia, no eta on a fix. Anyone that's seeing this go through nvidia support and file a ticket. Hopefully they can get it fixed in the next OTA.
I, too, only get H+ signal from TMO on my Shield. While it's normally fast, it sometimes drops and goes to E(DGE) or none at all.
EDIT: TMO could find nothing on their end via online chat. I'm going to test the SIM in another LTE device, and see if its a SIM issue. Waiting to hear back from NVIDIA. Really hoping our coming-soon 5.0 update fixes this!
EDIT 2: I just heard back from them that the TMO issue is an open bug "and will be fixed in a future update".
shield vs lte?
Yours at least connects, mine wont even do that I probably go to local branch again tomorrow if things wont change by the morning. I hope it works, but i cant activate the sim. Shield recognizes the card, under connections it says T-mobile but every time i turn off WiFi and try to activate the sim via cellular data, it keep telling me theres no connection yet i have 2 bars of their signal
So this means that I could but the 30 dollar a month plan? 5GB data, 100 minutes and unlimited texts?
Did anyone that was having a problem with LTE ever get it resolved? I just picked up the LTE version of the Shield tablet and have yet to see LTE and my phone is getting it fine. I hope a solution was found.

Yep, I'd be interested as well. I got that tablet since a few months and have problems with the radio too. I'm running LingeageOS 14.1. The latest few builds didn't even find the sim card anymore. Today I got back to stock rom for testing. Sim card is there, but it loses the radio connection every few seconds.

I just tried T-Mobile: works like a charm. It seems like Vodafone is causing the trouble. I've tried two different SIM cards and have the problem with both. Country: Germany.

What LTE band is your phone connecting to? I'm assuming you are T-Mobile? If you're in a band 12 area you might be out of luch as the North American version supports bands 2, 4, 5, 17, 7.

Wrong signal strength reporting on G920i?

Weird issue I'm having on a G920i. In Settings -> About Device -> Status, the signal strength is being reported incorrectly. When I first boot the device, it will show accurately and will vary from -90 dBm to -100 dBm when I am at my house, which is consistent with every device I've ever owned. However, after 30-45 seconds, it will start reporting at "-113 dBm 0 asu" and it will simply stay there and will never change, even as I move about. The number of bars in the signal strength icon on the status bar will even change, but in the Status menu, signal strength simply stays at "-113 dBm 0 asu" permanently. Connectivity seems to be fine--I have no problems making calls, browsing the web, etc. The signal strength in the Status menu simply seems to revert to and stick at 113 dBm 0 asu with no explanation or other impact on the phone.
For what it's worth, I've tried both the New Zealand and Singapore AOD1 firmwares from Sammobile.com. Same problem on both. I'm on AT&T in the U.S.
Anybody else seeing anything like this?
Yes it seems both the g920i and g920f all have this problem. Every single device. Please get in contact with Samsung about it, the more people that complain the more likely it will be fixed.
@mupet0000 & @phositadc I've seen you guys in a few forums talking about the Galaxy S6 SM-G920I signal issues... Mine is the same! Swapped 2 phones already and they have awful lte reception... I was hoping a different modem/baseband would help but it looks like it doesn't....plus a few soft reboots as well what's going on? Have you guys experienced any reboots? Can this be fixed with a software update?
OK checked mine and its yes your right. -113 in status however if you type *#0011# in your dialer you'll see the better reception reported. Interestingly this did not happen when I was on the Cricket towers(At&t). I just switched to T-Mobile and I now have the -113 status. My speeds are great but I can't side-by-side compare the radios to anything to know if there is a real problem.

@mupet0000 & @phositadc I've seen you guys in a few forums talking about the Galaxy S6 SM-G920I signal issues... Mine is the same! Swapped 2 phones already and they have awful lte reception... I was hoping a different modem/baseband would help but it looks like it doesn't....plus a few soft reboots as well what's going on? Have you guys experienced any reboots? Can this be fixed with a software update?

No reboots here. I flashed the aod3 modem last night and things seem a little better on AT&T. On the aod1 modem, I was not getting LTE in a bunch of places that I've always had LTE before. I know the g920i has frequency support for AT&T LTE bands, and I do get LTE, but I must say so far the experience has not been as good as other LTE phones I've had. Not sure if that's the modem firmware to blame or the hardware itself. Probably firmware.

Hey all, I'm in the UK and I have the SGS6 edge on the 3 network here. I use my phone for tethering at all times as I do not have wifi in the house. with my SGS5 before this I could easily run my PC , Tablet my son mobi and his gaming PC all at the same time with no issue. The S5 would run a full signal and load very quickly HD content.
My brand new S6 is disapointing singnal wise from straight out the box. I noticed my signal level fluctuating up and down but very rare dose it show a full signal level. and as for teathering I am finding it very hard to live with.
I will be suprised if Samsung sort this out with firmware. I just had a 150 MB firmware update yesterday and my signal level is the same.
I remember my Nokia N96 having this same fault, and although it was all over the internet back then, Nokia did nothing in all the firmware updates I had. I was going to sell my pristine 7 month old S5..... but I think I will hang on to it for now.
Hey guys, I am on the latest OTA released by Samsung (AOE3 built May 7th) and the problem is still not resolved. LTE signal still awful and LTE signal strength still -113. So far so bad. I have contacted Samsung again, and tomorrow I have a phone call with their support where they will remotely access my phone so I can show them the problem. I will show them and see how it goes, and I'll report back here.
I will make it clear to them that the signal strength is worse than my 2 year old S4, and I will demonstrate the incorrect signal strength value to the support agent. If they tell me it's a non issue or they make some silly excuse instead of investigating, I will simply sell the S6 and get another phone.
This is a huge issue and I'm disappointed that there aren't many people noticing this or reporting it to Samsung. The more popular the S6 gets, the more people will notice that their old phone holds a better signal.

I think it is a widespread issue... I always have 1 bar lte and under my signal status it say - 113dbm which is zero service... It never moves... I'm gonna try custom rom and see if that help but it obviously a antenna/modem baseband issue... Also someone mentioned it could be because the Galaxy S5 uses Cat 4 lte and the S6 uses Cat 6.....its very disappointing! Hopefully it gets fixed or I'll return to the S5...i really want to like this phone..... But Samsung is making it hard to
I don`t think there is anything wrong with the signal. even if I only have 1 bar the phone is perfect during calls and my LTE/4G download speed is even over the provided speed my carrier provides, I think it`s just a bug that it`s showing less signal then what it actualy has.

This is true. It's simply a bug that shows the wrong signal strength - mine shows -113 but I'll have 3 bars so that makes no sense. However, if you ARE getting a bad signal, that is a different issue altogether.
(btw I started a thread about this already several weeks back)
Spoke to Samsung on the phone, they didn't need to remote access my phone to see the issue. They had an S6 in their office and they told me they saw the signal at -113dBm just like mine. They say they have passed this onto the relevant team and hopefully it will be fixed in an OTA and I should stick to the United Kingdom BTU firmware (the correct firmware for my region).
We will see if this gets resolved. They definitely know about the problem now and have seen it with their own eyes, so I'm hopeful.

Ok.. Thanks... I already read through that thread too... Been trying to figure out if it was just me or alot of people..... Seems like the 920f is getting more updates that us.... 920I......The latest is AOD3 right? Today I'm gonna flash a custom rom for 920f and see if there is any change....
*edit* just checked Samsung live update... AOE3 was just released for 920I for TTT I guess is a country called Trinidad and Tobago... But that is the firmware I've been using.... Hopefully this will help... Let Ya guys know
*edit #2*...ok guys just updated to AOE3.... Bars still show low but the signal status is working and it's showing that I have a better signal than with *#0011*... The - dbm and asu is now extremely close to my S5... So in conclusion the signal is strong it just doesn't show it in the bars like previous Galaxy's

Using the EU Version in the US

I'm considering buying the European version of the xz premium for use in the US, since it comes with the fingerprint reader already enabled, and is about $100 USD cheaper. However, I've seen some people raise concern over the cell reception when running the European firmware. I'm wondering if anybody knows if this could be due to the European firmware not matching the physical bands included on the U.S. device (of if that's even a thing), and also if that could be somewhat solved by just getting it straight from Europe. Is there anybody that has the European version that could speak to the cell reception quality in the United States?
If you use the European device in the US, you also have to change the settings for the used bands.
There is an option to change used frequencies in *#*#4636#*#*. Guess that would make a difference since the hardware is always the same.

This is exactly what I was looking for. Thanks. I didn't know that they all had the same physical bands
You don't need to change anything.
When you pop in US sim, all bands are available and appropriate LTE CA combinations are loaded.
3G calling will work, but you will miss out on VoLTE with euro region firmware.
Bought my XZP from Clove UK.. Using it in NYC.. No probs with reception.. No need to change anything, all I did was pop in the sim card, working great ?
I recommend to change the radio configuration to "United States" just in case.
I just popped in my AT&T sim and no problems. I did set the bands to the United States...makes no difference as everything works the same.
UK model G8141 here in US. I just put my AT&T sim and got LTE and great connection right away. No worries.
I ordered mine from Clove as well, and while it does seem to work just fine with my AT&T SIM, I always have only 0-2 bars of signal and the phone always shows 4G/4G+ instead of LTE. Anyone else have this issue? I've been trying to do some digging to see if perhaps there is some setting that I need to adjust such as the APN used or something to get better signal strength. Thoughts?

First of all, 4G in the UK is the same as LTE in the United States, so no issue there.
Do not look at the bars as this can be manipulated by the programmers. To see how strong your signal really is you need to go to settings > about phone > status > SIM status. The lower the number the better. I am fairly certain that if you DO NOT use 4G you will get a stronger signal which may be perfectly fine unless you need a real fast signal. By not using 4G you will be using 3G. Hope this helps! :good:

Oh good. I was wondering about whether or not the UK actually called it LTE like we do here.
My average signal strength seems to be -119dbm 99asu pretty much regardless of where I am in my city. It just seems weird since my Huawei Mate 9 got consistently better signal than this in the same market, with the same SIM, supporting the same frequencies. Just makes me wonder if there's something I'm missing or if I should try getting a new SIM from AT&T.

I doubt that a new SIM will help anything. Those numbers are quite high. Too high in my opinion. If you do not stream videos or something that needs very fast LTE signals, then I would choose to not use 4G. You should get a much lower number (better signal) and everything will still work just fine.

Have you tried re-provisioning the phone? Maybe have it pull down the settings and reboot. I got mine from clove and am on AT&T as well... Pulled the sim out of my SGS6 and everything seems to have worked perfectly.
How are your speedtest results?

You mean having it download mms and Internet settings, then reboot? I've done that a couple times but I never rebooted after doing it. I did notice that in my APN settings, there are two for AT&T and I can't find an answer as to which one to use. One is called "phone" and the other is "nxtgenphone".
My download speeds aren't terrible but they aren't super amazing either. Last I checked it was 35mbps down and about 5mbps up. I'll try reprovisioning and restarting and see what happens. It just sucks not ever having more than 2 bars no matter where I am.
Edit: just tried downloading mms and Internet settings again but it didn't help. Maybe I should reset my network settings to default and try again just in case?

Mine is set to nxtgenphone. I really wouldn't focus on the bars. My z3 was also from the UK and did the same thing. You can check under the diagnostics settings screen to see what your data connection is or try doing the magic combo number to see what bands you're set to.
Is there anyone with a phone on the same carrier that would pull up their signal strength info so you can compare the actual numbers?

Maybe someone can give me some but others have told me that averaging -119dbm 95asu is a pretty weak signal.
Others have said I shouldn't need to change any settings in the hidden phone menu, but I set it to United States just to be safe. I didn't mess with any network settings in there aside from that.
Edit: checked radio band setting and set it to United States. Network preferred type is set to LTE/UMTS auto (PRL). Not sure if I need to change any of these settings or not.

Ouch, yeah... that is what my signal is like when I'm in the office and the repeater is down. I can't send/receive texts most of the time.

In your APN settings for nextgenphone, is the APN protocol set to IPv4/6 or just IPv4?

It's set to 4/6 but I don't have a v6 address assigned at the moment.

Whenever I test it in the hidden menu the IPv6 test always fails. Even AT&T's official documentation says not to use the IPv6 but I'm not sure what to believe since the downloaded settings have it enabled.
