Calls made when on LTE keep getting dropped - Nexus 5 Q&A, Help & Troubleshooting

About 3 out of 5 times when I make a call when I am originally on LTE the phone call drops. I am on AT&T and when I make a call it switches from LTE to H+ then all of a sudden it just completely drops signal and thus the call and about 3 seconds later regains signal. Does anyone know what may be causing this issue or has had this issue? I am on 4.4.4 Stock with Root.

Well dropping calls isn't normal, but dropping from LTE to H+ is. VoLTE isn't really a thing yet. Calls don't work over LTE, so when you make a call it automatically drops to H+. That's normal behavior.
Did this just start happening out of the blue? Or always done that? Make sure you have the correct APN settings. If so try calling your provider and see if there's anything they can do for you.

Sorry forget to mention I knew that was normal for the drop to H+, but yes the signal drop is not. Well it started out of the blue. IS there a thread on here with what should be the correct APN settings? Also my old nexus 5 started to do this before I returned it under warranty for refurbished, then I had a moto G lte for a month worked fine, got a refurbished (due to warranty) and started again.

Here is a graph of my network coverage to show that the signal just drops.

Mine doesn't seem to have any particular count pattern, it happens very randomly, usually when attempting to call someone and once they pickup on their end, my phone would hang up. This happens maybe 40-50%of the time, can't estimate a guess, but i can say that it happens enough to piss me off. I've checked my AT&T APN, which matches to what the carrier has it set, i even went and got my SIM replaced, rebooted in safe mode, gps works, so it's not a third party app causing this. Last resort is factory reset, although I'm almost positive that won't do anything. I'm currently also running android 4.4.4 stock aosp on a 32Gb N5. Device was purchased new in early may 2014, and came with android 4.4.2 preinstalled. The random call drops issue started in early October, a few months well into 4.4.4 update. All I've found online is that i it has something to do with a missing cellular radio, but to be honest, i don't want to mess with those as that may cause further problems. Called Google, and they act like they're clueless about this issue, all they can offer is a replacement, which is nice, but to be honest, it's probably going to happen again even with the new device. My coworker has the same issue with his 16gb N5 black model. If anyone with this device trying out android 5.0 lollipop preview can chime in on if this problem still persists, would be very awesome. I'm going to wait and see when the official android 5.0 comes out, if that fixes the dropped calls problem, then N5 can be used, if not then I'm getting it replaced and reselling it, may go with the moto x+1. So either a good portion of nexus 5 devices are factory defects or this really is a cellular radio problem. Really hope that lollipop will fix this issue.

The APN only handles packet data and not voice so that shouldn't be the issue.
I would try setting your phone to 3G only for a while and see if the drops still occur when you are on 3G prior to the call.

Yea it wasn't an exact count but like 3 out of 5 says, enough that is annoys me. Tried all those as well and like I said I have a moto g lte that the sim worked in so it isn't the sim. This is my refurb unit, but the other one I have since November started to do the same thing in August as well on 4.4.4 never had an issue before that. Where did you find that if you don't mind me asking? I am comfy enough to mess with that stuff, so i'll give it a shot.

Already did and it doesn't but is an annoyance then since part of the price of the Nexus 5 is to have LTE and I am not getting the full product then which is not ideal.

I found it here (just take away the spaces after .com and after 02/): ianmarmour.com /2014/02/02/ google-nexus-5-fixing-modemcellular-issues-on-34g-networks
It's an older post from February, but seems to have the best details and fixes. If you simply search nexus 5 cellular radio issues or nexus 5 4.4.4 call drops, you should find a lot of these recalls from lots of N5 users. I'm tempted to try it, but don't really feel like sorting all my files in case i brick my device. I'm also not sure if ota update will work if i tinker with cell radios. Otherwise that's the page containing all the details you'd need including links and step by step guides. And hey if it works for you, let me know, maybe I'll try it out if it goes well for you.

Exactly, i know that's totally possible, but i wouldn't want a smartphone that has no lte and/or hspa+ service at this point in time. This seems to happen wherever lte isn't as strong or available but hspa+ is. I think the modem responsible for switching between lte and hspa+ causes calls to drop. I took note of it a couple hours ago when i attempted to make a few phone calls resulting in instant call drops. Seems to do it while switching from lte to hspa+ network. I just wish Google would stop burying their heads from the outside world like an ostrich, and get in top of this. I mean this is their flagship device until N6 goes on sale. They should seriously fix this issue or at least stop denying that they've never heard of any complaints with their N4 and N5 customers. I love this device, but a simple fix like this not being addressed by Google is not very professional, especially because it's primary function is to call people. I'm really tempted to flash those radios, but really want to see if Google addresses this issue with an official ota lollipop update.

part of the price? no. you dont see any phone more expensive because it can handle lte. your issue is with your network, and its signals around you. as we all know that the lte available can not handle voice calls. your isdue involvez lte handing off to H or 3G. thats where your network comes in.

Then why does my moto g work fine in the same locations? And LTE isn't more expensive on a phone? Please explain then how a LTE phone is more expensive then the 3g variant. Go compare the moto g to moto g LTE. Defeats your argument.

lol, ok. the moto g variants are an exception to the majority. their already cheap price point being the reason.
those are two different devices, with differing hardware. its possible that moto can catch the signal from a little further away than the n5 can. the n5 was made less expensive because they used less expensive hardware in places. a shorter antenna being one of those places.

anyways, if you bought it from google, you can request an exchange.

I wouldn't try any hardware mod, etc as the issue is with the software. This kind of thing happens to me also, regardless of where I am or what network I'm on (tested this with a friends AT&T sim also). In the settings menu my signal strength just says "0" (kid you not ZERO) and sticks there until I manually set the phone to 3g when I go to a place with weak LTE (like a basement).
DISCLAIMER: I am only assuming this as I don't know that much about this topic, but I think stock 4.4.4 doesn't understand that LTE can still be received at worse than -115dbm and causes this fault. It doesn't matter which radio you flash (using the newest dev preview radio on 4.4.4 still has this issue, but on 5.0 it works flawlessly), what network you are on, where you are with strong LTE coverage... If you go to the wrong LTE dead spot you have this issue. It's as if the radio is saying "I'm still good on LTE" and the phone says "-115dbm isn't good we need to switch" and the radio says "I'm still connected to LTE though" and the conflict causes the signal to go to 0. I don't think it's got anything to do with the handoff from LTE to 3G either (but it might, as I said I'm no expert). -115dbm seems to be the doom number for me on LTE with 4.4.4.
Try flashing the new dev preview if you want LTE. No network = 0 bug. Hell I can even get LTE in my basement (at worse than -115dbm, of course). I had to flash back to 4.4.4 though, too many games/apps not updated yet.
Long story short, this is fixed in Lollipop. Less than two weeks...

[Q] Signal drop/No service

Just wondering if any one else gets this, sometimes my signal just drops out and I get no service.
Then it comes back it does not happen all the time, I live in a big city Leeds infact so signal is quite strong.
Just wondering if it could be a fault with the phone?
Thanks
I've noticed it happens to me too.

It is definitely possible.
I'm on AT&T and have the correct APN settings and have called AT&T with my IMEI. I have significantly worse signal than with my HTC One X. I am not comparing bars to bars, but rather where the signal drops completely. In places where I had low signal but still connected I now have nothing.
Straight talk using at&t Sim and notice radio drops..

T-Mobile on stock ROM i had my first signal drops.
I was fine (or at least never noticed them) from the time i got my phone (day one) without any drops here in orlando.
Drove over to Tampa/Venice Beach area this past weekend and noticed some drops. Had about 6 drops according to my battery stats in 2 days. i had good to excellent coverage the entire time except when it would drop comlpetely (outline of signal bars)
would connect in a couple seconds, but i noticed over night, it would drop for a pretty large amount of time (like 10-15 minutes at a time.)
Mmm defo seems like were all having the same issues, wonder what it could be
Sent from my Nexus 5 using Tapatalk
I had this issue too, and here's how I fixed it:
By default LTE is enabled, meaning the phone will periodically scan for a LTE network. If you're in a big city, you're likely to find one. Your phone will attempt to connect. However, it fails, meaning it will have to rescan the HSPA bands to connect back. That results in a few seconds of no service. Why can't it connect to LTE? Because by default, the APN is not the LTE APN, for Rogers at least. I'd assume AT&T would be the same. You can test this by dialing *#*#4636#*#*, selecting phone info, and selecting LTE only. You'll see that there is no service. I tested this in an area I knew had great LTE coverage, and that led me to the conclusion that it's LTE causing the signal drops.
So how to fix? Simple, just change your APN to the LTE APN for your carried. To do that go to Settings -> More -> Mobile Networks -> Access Point Names. If you're experiencing this issue on Rogers, change the APN field to ltemobile.apn. If you're on another carrier, you'll have to search for their LTE APN configuration.
After doing this your phone should start connecting to LTE again, and you won't get those annoying signal drops.

So yeah the next update will probably fix the issue. It's not so bad in the meantime, Lightflow sill notify you that your nexus has lost signal, and you still get the internet and incoming calls.
We're not alone. Supposedly Google is "aware" of the issue.
i've hcanged my setting from '4g' to '3g' to see if i notice a difference (hopefully will) then when 4g is released or i get a 4g sim, can move it back up
Yes, I'm having issues too. The real problem is the fact that I have a Wilson cell booster in my home (supposed to have up to 5000 square foot range) and my n4 had full bars most everywhere inside. With my n5 It shows 1 to 2 bars if I'm lucky and quite often drops to none! The only way to get full bars Is to stand right under the indoor antenna. Not impressed, and I sure hope this is fixable!

I hate to revive a dead thread, but I was wondering if people were still having problems. Once or twice during the day that I can see I will lose signal for a few seconds only to have it reconnect. Running 4.4.2 so the latest update did nothing to help the problem as far as I can see and I have messed with my APN settings. On AT&T. The Google thread seems to have a lot of different problems on the same thread, and it is a bit unclear if people are still having this problem. This is very annoying for such an otherwise spectacular phone. Thanks and sorry again for reviving the thread... :fingers-crossed:

Appreciate the speedy reply. Hope Google gets on this fast. I also have LTE connection issues which has plagued both this and my original device so I am pretty sure its a radio issue. The phone loves to stay on HSPA+ even when there is a decent LTE connection: it's last in the pack to connect to LTE and first to disconnect when compared to others on AT&T.

My N4 with a combo radio sticks to LTE a tad better than my N5 with stock radio. Sadly, morrislee hasn't fiddled and combo'd N5 radios, and I'm not sure they've been tested and sussed out like the N4 radios. Citing the fact some with issues have flashed all the radios so far with minimal success means we wait for Qualcomm, after Google kicks them in the you know where.

Please Help! Nexus 5 Signal Issue(Not rooted)

I just got my Nexus 5 and I haven't root it yet. I notice that everytime I don't use my phone 5-10 minutes or hours, the signal will be lost and asking to reboot my phone. I can't tell when it's up or not. Sometime I take multiple reboot to get signal back up then it happens again and again. Is there a way to fix this problem without rooting? I don't think it's the Sim Card because I used it on my nexus 4 without any problem. or Just my device isn't good one. Please help!

I didn't root my phone yet, and I'm running 4.4.2 now. It's annoying to keep losing signal and it's back again. Even I have signal, I only have 1 bar compare to my old Nexus 4 has 3 bar or HTC one full bar.
I don't want to root it if its not solve this problem, I will have to return it.
There was an issue on 4.4 where it would randomly give you the "emergency only" message. You would have to turn on airplane mode and then turn it off, or reboot. But people have been saying it was fixed with 4.4.1/4.4.2.

The radio however sucks in 4.4.2 and was better in 4.4.1
perhaps we may see 4.4.3 to fix this?

I think it might be overall worse, but luckily I actually didn't see any decrease in signal in my area. I was really worried about it because I already have really bad signal in my house but 4.4.2 doesn't seem to be worse for me.
You guys forget to mention that Google cheaped out on the antenna to cut costs. Best you can do is to flash your carrier's radio over the generic one

I'm sorry, but you're dead wrong. SO much misinformation here. First off, there is no "carrier" or "generic" baseband. There is only one baseband. Second, antenna design requires a lot of engineering to maximize signal efficiency when you're dealing with interference from such things as wifi, nfc, Bluetooth, metal construction in the phone, etc.. I'm not sure what magical material you think that cell antennas should be made of that will solve issues?
I just got off of the phone with Sprint. They show that there is an internal memo on the issue and LG is aware of it. They will be pushing an update as soon as it's ready. Sprint will also be pushing an update for the Airave to help with the issue. The support rep told me that it is an issue where the wifi and LTE radios aren't playing nicely together and causing a conflict. That's why everything seems to work fine when 3G is set as a preferred network.
It's an issue that still hasn't gotten fix as seen here.

I'm going to have to buy a different phone because I have no signal almost everywhere I go. I switched my SIM to my wife's Note 2 and I had great signal and her SIM in the N5 had no signal.

The issue seem to be gone after couple days. I checked signal strength app, it shows same even though it shows only 1 bar.

AT&T G2 LTE signal problem?

Hey all,
I recently picked up a LG G2 (second hand)
and I believe I have some issues with the phone not picking up LTE so easily.
Before this, I had Iphone 5, nexus 4, G Pro, Gnote2, etc... and they all picked up LTE just fine at my home
However, G2 rarely picks up LTE signal and it is mostly on HSPA+ (4G Icon) I believe.
I took it into AT&T store to see if I could get a new sim card but when I got there, the phone picked up LTE no problem.........
Looks like many Sprint users are experiencing same issue.. is there a fix for this??
*The phone is currently on stock / non-rooted 4.4.2
Thank you in advance!
I'm in the same boat as you, my data will work for a good 30+ min and then all of sudden no network for 30 seconds or so. I've also been unable to connect to a lte signal I've only been able to use hspa, searching the threads on here have been hit and miss with a lot of vague answers but nothing clear cut if anyone's dealt with this and has a clear fix it would be appreciated.

A little update to this, yesterday I went to AT&T to see if I could maybe clear this up with a new SIM card and while waiting I checked out the two G2s they had there, these two display phones were literally 10 ft apart and one had lte while the other one was stuck on 4g only. I think this is looking more like a hardware issue now after checking out both store phones on display, I'm going in today to swap out my handset to see if this will solve it.

Here's another update for those with lte or signal loss issues, after trying everything I could find on these forums the only answer was a warranty swap out, as soon as I put my SIM card into the warranty phone let showed up and after half a day I haven't experienced no random signal loss at all.

Interesting...
This is interesting. Currently running CM11 latest nightly and I thought it was due to CM codebase. It looks like non-CM related?
Please keep the details coming. When I have time, I will flash a stock ROM to see what happens. But at this point, it looks scary that maybe hardware problems might be there.
For comparison, 2 iPhones literally next to G2 had 3 bars with LTE while my G2 had no network.

After a full day and a half use now im fulling supporting the theory of a hardware fault. Before returning my phone for a replacement i was fully rooted on gardys kit kat rom with recovery, i had read that supposedly rooting or flashing was apparently breaking lte so i went back to the stock jellybean rom only to discover the issue still there, i then fully updated to the over the air kit kat update which also did not solve the issue. It really does look like theres a issue with the phone itself.

Oh wow. Thanks for your reply.
So i have tried working on this and so far no good.
LTE picks up good when i walk into an att store and that is causing difficulty with store workers..
I get stable, steady connection with hspa+ but rarely pick up LTE..
What is the process of getting a replacement? Its way over 15,30 day period for me..

For me lte did not work at all even in store, I can see where you might have a issue if they can't reproduce the issue but just be persistent and they should take care of it for you. As for warranty you have a year from your purchase date for a warranty claim through At&t, I went through a device support center which you might have depending on where you live otherwise you can send it in. You must revert back to a complete stock state or you will be more than likely denied.

Got it fixed after several attempts with new sim cards! Picks up Lte fine! Wootwoot
My fix
call att tech support make sure that the lg g2 imei matches your line/sim card
So I went through a bunch of phones in the past couple weeks, I have at&t service but my last phone was verizon droid maxx. Next I went to the AT&T store and he put my phone number under the new sim card for my AT&T LG G2 but the rep didn't ask me for the IMEI or look at the phone at all, he just got my line on the new sim and I left. I noticed the phone was going back and fourth to LTE but it was 4g (non LTE) about 70% of the time. I changed APN settings, I updated, nothing worked. Then I remembered a long time ago that if you go from android, blackberry, or iphone to another type of phone you would have to call att and make sure something was changed so I called att tech support and asked if they would put my IMEI under the new sim, the tech said yeah I should do that because currently my line doesn't show I have the g2 (make sure to call tech support because online it'll show you have a g2 and if you call costumer service usually they will see the g2 too) and after that i reset my phone and got LTE 100% of the time since then.

[Q] No signal strength all of a sudden

Hello,
I bought my Nexus 5 on the 11th of December 2013 and it had been working flawlessly ever since. Since last week, I started noticing the occasional signal drop and I'd be out of cell reception but would usually be back up within no time. However, yesterday, out of the blue I'm travelling on the highway and my signal strength disappears never to come back again. I've tried the following:
- Restore old backup (including EFS)
- Went back to stock from PA
- Upgraded to the latest radio
- Took back cover off to see if anything was wrong but found nothing.
- Tried another SIM card
Nothing worked. My SIM card works fine in another phone. Everything else such as WiFi and Bluetooth works flawlessly but I just don't get any reception.
This is very disappointing and I have my fingers crossed hoping someone can help me with this since I didn't plan on getting a new device for at least another year especially after paying $520 USD for my phone here in my country.
Thank you for looking.
im having a similar problem with the radio after the last few otas. im getting a lot of dropped calls on 3g aws...
im going to try to revert to an old radio as i don't think this is a hardware failing issue..

Flash stock firmware with fast boot. If its the same, its a carrier issue....call them to see. Or its hardware failure.
just wanted to post my fix for this issue - very disappointed with Google that i had to do this...my provider is mobilicity canada (3g aws band fyi)
flash krt01b radio from this thread...
http://forum.xda-developers.com/showthread.php?t=2514095
this is *not* a carrier or hardware issue (at least in my case)
seems others are having same issue
https://code.google.com/p/android/i...s Owner Summary Stars&groupby=&sort=&id=70878
Then it is a carrier issue....cause on Telus in Canada....never had an issue with any radio version. ?
telus would have a stronger overall signal but uses AWS band for lte which is different than mobilicitiy 3g aws...
I'm not disagreeing.... Just saying its the carrier....not Google.
See my point?

are you saying mobilicitiy is purposely weakening their cell signal cause they are almost bankrupt ?
i still blame google i had no issues with the radio before they borked it...

Just saying that unless many have the issue with the phone or radio, then its an issue.....if not, it isnt .
So in this case, it leaves hardware or carrier....assuming a stock flash didn't help.
If flashing another radio helps the OP...awesome!! But the new radio does work fine for the mass majority.
Hope it does work for him tho!

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?
Question: are you using a custom DNS or VPN?

It's also happening to me, I don't use any VPNs nor DNS. I think this is a OnePlus Problem, maybe they'll address it in the next update. Let's report this problem guys
Edit : I'm not on a Verizon version, mine is IN2010
Funny thing is whenever chrome freezes, going to the home screen and returning back to the app fixes the issue ??*

It's not OnePlus, it's Chrome. Acts the same way on the Essential PH-1. Try Safari or Microsoft Edge browser, or any one that uses Android web view.

The fix is to install another web browser, then go to apps in the settings and inactivate Chrome. Haven't had single hickup since I did this.

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
