LTE issues on att - Nexus 6P Q&A, Help & Troubleshooting

Is anyone else experiencing lots of issues with lte on att. I'm always getting h even when I'm in full lte coverage. If I toggle vpns and keep hitting reset to default eventually I will load full bars of lte. However if I reboot my phone or sometimes even just going in WiFi I'll be back stuck at h again. Anyone else experiencing this or did I just get a lemon?

Omg im having this issue thinking of getting a new sim card to see if it fixes the issue keep me updated [email protected]

Same issue here, I have to keep flipping APNs until it sticks. There are other threads out there talking about this, have either of you registered the 6P with AT&T? I don't see what help it would be if you are already on an Android plan but the thread had suggested it.

I lose LTE a lot but outside of the symbol disappearing nothing feels different with what I do.
Its very annoying and the only phone I've ever owned with this bug.

This is a known bug on 6.0.1. And it has not been addressed and doesn't look like it will until N drops or at least that's what I've read anyway. Who knows when a fix will come but this effects everyone ot just at&t. I'm on Sprint and I get 3g when I'm supposed to be getting LTE. A reboot or airplane mode toggle will sometimes bring LTE back but it soon goes back to 3g again. This is a bug in Marshmallow for our Angler from what I've read.

I've had this happen occasionally. Usually happens if my phone is very hot from playing games

Same issues for me as well. Same thing on stock or custom roms. I believe this is a bug Google will have to fix. Lets hope for sooner rather than later.

Yeah same here but I don't really care to be honest.

is this LTE bug worth staying on 6.0 over 6.01 ?

[Q] Network keeps restarting on T-Mobile

I'm making this post because I need some assistance...I've already searched around this forum for a few days but it seems like I may be the only one with this issue...
I got the phone a few days ago, from day one I noticed I've been having network issues. By that I mean every time I try to use any apps that require data such as facebook, youtube, instagram, chrome, google now, and especially speedtest, my network would die for about 10 seconds as it reconnects.
All bars drop, I get the message of "network unavailable", and slowly edge speeds come back, followed by hspa.
I have tested this throughout all parts of Los Angeles already.
I have also replaced the micro sim card twice.
I also hard reset the phone back to stock.
Also reset the APN settings.
Two other people I know of in the area, their Nexus 4's work perfectly fine.
I'm all out of options, the T-Mobile tech support team is also out of options, i was recommended to send it back to Google but I don't want to do that unless it's absolutely necessary as a last resort.
I was just wondering if anyone is familiar with this issue or any suggestions as to what to do?
Thanks so much

Seems like a similar problem to what I'm having. I always just randomly lose reception. Reception is already really really bad for me, but it seems like it's whenever I pick up the phone the network goes out. It's really getting on my nerves. Most places in my house I get no reception. But it's the weirdest thing that happens. I can be sitting on the couch using my phone, and have no bars. But then I set the phone down on the couch to go grab something from the fridge and when I come back I'll have received a text message and I'll have like 2 bars! But then the second I pick the phone back up reception goes out again.
This has been going on for the last month for me, and it's especially bad at work but almost nowhere else.
I think (though I have no concrete evidence) that it's because of their ongoing 1900mhz refarm.
Someone should call tmo and find out.

yep..i'm starting to feel like it's 100% hardware related to the antenna. might have to contact google and see what's up. hopefully if i send it back they won't take a month to replace it haha
Sounds like a faulty antenna to me :\

I've experienced these problems on AT&T (MEdia Net, not DataPro) as well. It happens regardless of how good my signal is. I haven't experienced the other problems you are a time else mentioned.
On the NPR app, it results in some sort of error such that I have to reboot to get the NPR app working again. The app doesn't say something has gone wrong, but it won't load any audio and will hang after waiting.
The signal drops, then picks up again and goes straight to HSPA+:15. This happens to me on the road quite often and I just switch to onboard music rather than fiddling with my phone while driving. The issue has occurred a few times while in Maps, but thankfully I knew how to get back from where I navigated to.
EDIT: Just want to clarify to the poster below me that this occurs REGARDLESS of how good my signal is. It happens when I have better than -50 dBm (I think -70 gets full bars, although I've even seen full bars at -90!) so it can't just be a low signal issue.
I'm pretty sure this happens to all nexus 4s unfortunately. Anyways that is in a poor connection area had this happen.
This happens to me at home. Bounces from 0 to 3 bars constantly. But if I'm outside in an area with strong signal I never go below 3 bars no matter how I hold it.

Ive been having the same problems with my n4 in tmob. I get a lot of 3g and sometimes i get no bars. I hope its not a hardware issue. Im in many miami and ive seen a couple of threads about this

I don't think it's an antenna issue. It was happening on my Galaxy Nexus for a few weeks up until I got the Nexus 4, and prior to that I *never* experienced total signal loss like this.

The first couple weeks I had the N4, I wasn't experiencing any connection issues, but for some weird reason they started last week. It wasn't even fresh after I flashed a new ROM. I think perhaps it's a network issue that is somehow specific to our unique phone and plan combinations and our areas. Anyone using AT&T's MEdia Net plan in Georgia?
I think you guys may have gotten my issue a bit confused, what I'm trying to say is my signal fluctuates depending on location like normal, however only when I use apps that are solely dependent on internet connection, my entire network goes down.

Yeah that's what I'm encountering as well. I wonder what these other guys are talking about?
My network goes down regardless of whether I'm doing anything with the phone or not. I could have just the screen on and it'll be lying on the table and I'll see it go from 2 bars to empty and eventually back.
It's especially bad at work where I have terrible signal to begin with.
Forgot to add.. my coworker with an HTC 8x and another with a Galaxy Nexus are getting the same issues.
So, it's a network problem for sure. I'll post this on the tmo forums tomorrow and see if I can get any official word on the matter.

This exact thing happens to me using straight talk att Sim.. Right now, full bars to zero, then back. Sometimes it jumps to roaming, and seems to get "stuck" and I need to turn airplane mode on/off to fix it

same :crying:
I experienced something similar on my N4 and called T-Mobile tech support. They had me power off my phone and they "reprovisioned" or "reprogrammed" my data connection or something like that. It's been better since then.
Posted on t-mo forums, let's see if they can be of any help.

Please add on to the linked thread, the more attention we get on this issue the faster we'll get a solution, or at least an idea of what is causing it.

last night after midnight my phone suddenly couldn't get a signal from t-mobile. i thought i screwed it up, but then i took the sim and put it in my galaxy nexus and it had the same issue. so i went to bed and in the morning it was working fine. i suspect t-mobile was doing stuff to their network in my area
Having the exact same problem today in Manhattan near Bryant Park. Can't keep a stable signal at all and data is connecting only in bursts. Hopefully this will be fixed soon or I'll have to look for other options than Tmo and my N4
What's the E stand for? 3G?

[Q] .48 radio breaks H+ in 4.2.2?

I'm not sure if this is covered anywhere. It's not a huge deal, but it is a little slower. My phone never goes into H+ with .48 radios on 4.2.2. All else is fine, but is this a common thing?
Also, I can still see the LTE option, isn't that supposed to be gone?
I'm on T-Mobile, if that matters.

I thought it wasn't only me! It happened to me today. The data was so slow!

Ah, okay. As far as H+ being dropped, hopefully I'm not the only one. Maybe there's some APN settings I can put in to hopefully change that as signal drops seem far less often so far.
Edit-
Freaking 5 minute limit. Sucks that I was inactive for so long with this account -.-
Glad I'm not the only one!
I'm getting about half the speed with H as I got with H+. I'll leave it like this for another day or so probably to see signal in other areas(Mostly work, where signal dropped every few minutes before), but if I decide to switch back to .33 radios, will there be any issues?
The 4.2.2 update didn't exactly break H+ for me, but I am definitely experiencing data "stalls" I guess you could say. Randomly when browsing the web, or doing anything using data it'll just stall... Sometimes for up to 30 seconds. I did experience the same with 4.2.1 but it now seems more noticeable (could be placebo). I have no problem with signal and get great data speeds when it is working right. I always have full bars while at home since I live about 200 yards from a T-Mobile tower. Kind of annoying tho.
Sent from my Nexus 4 using xda premium
I noticed the data stalls twice so far, Once during a speed test and another while looking around in the playstore. It showed was connected but the arrows disappeared and nothing was going on.
Is this just stock ROM's or something?
I'm on a custom 4.2.2 ROM (Xylon and was on CM10.1) and .48 radio, H+ is working for me.
Your APN settings are correct?
A stock rooted 4.2.2. Figured I'd give it a try before I flash ParanoidAndroid. I was on Xylon 4.2.1 before I went to 4.2.2, but I figured I'd give stock a try. And as far as I can tell, yes. APN settings are right.
I tried flashing back to .33 radios, no luck. Maybe I'm missing something in the APN, or it's ROM specific.

AT&T LTE Speed

After activating my 6p on AT&T I noticed slow LTE speeds compared to my Nexus 5 (not just speed tests, actual browsing/usage). Contacted AT&T support to verify IMEI and SIM information and they did some sort of SIM refresh on their end. After that I was getting around 70-80mbps speed tests for a few days but now the speeds have dropped back down to 5-10mbs (if that).
I've tried switching to PHONE and PTA APN's and no difference is observed. I am not on an unlimited plan so no throttling should be taking place.
My friend who is also using a 6p on AT&T is seeing the exact same behavior and had the exact same results after contacting support (fast speeds after refresh but slows down after a few days).
Has anyone else been experiencing this issue with AT&T or any other carriers? I'm not sure if this is a radio firmware problem worth reporting to Google or something on AT&T's side.
I'm having this same problem, my s4 was at least double the LTE speed of my 6P, I've been searching for a fix but this thread is the only one I've found so far, I did see VZW post where you can dial a certain number and select bands, I'm hoping someone can share a fix life that for us on AT&T
same here ... very slow compared to all the other phones I have that are AT&T branded and much slower compared to Nexus 5 and OPO. Also every time I call somebody, phone drops down to "H" and then connects the call. No calls over LTE.
I'm having the same issue and lately I keep loosing my lte and seeing only the H for 4g

yeah but i was having issues before the update
I wonder if it's something with AT&T network and this phone. I'll have full bars (LTE) and no service quiet often. I live in south florida, so we generally have great reception for every carrier.
The issue started for me as soon as I upgraded. I tried the older radio as well. I went back to Chroma 6.0 and all is well. I did star the issue in the tracker.
Well I just got off with att and they reset my connection to the network and so far so good. Lte all around. I will watch the next few days and let you all know

I have actually gotten the same problem, after updating my 6p to 6.0.1, I have lost my LTE and just stayed at H.
I haven't done nothing other than updating, I really hope this gets fixed soon, the speeds arent that bad but I am used to having LTE all around
Well I called att this am at around 8am and tight now at 6pm its been solid. They made me shut off my phone and basically set up my phone network wise as a new phone and boom LTE everywhere
Happening again. I reset network settings and boom all is well for two days
I found a recent post on reddit where a user was having issues with the phone connecting/losing LTE. After troubleshooting with AT&T support they indicated the "APN type" setting was missing an entry and in the improper order.
Changing to the proper order fixed his and others LTE issues and so far it appears that it has fixed my speed issues as well.
The fix applies to both nextgenphone and phone APN's.
Default APN Type on 6p = default,mms,supl,fota,hipri
Correct APN Type from AT&T support = default,admin,fota,mms,supl,hipri
Hopefully this helps.

Network type constantly switching

What's up your fantastic XDA people. As the title says , my Moto X keeps constantly switching between Network types. One minute it's fine and dandy on LTE and then it'll just randomly switch to H, and then to 3G or from H back to LTE. Does it randomly at any time of the day and also might even just lose LTE connection altogether momentarily and then it comes back after a second or two.
Running Stock Android 5.1.1 with no custom kernel or anything modified. Thanks plenty
Ive been having similar problems modified or stock still does it
Beginning to wonder if it's a widespread issue for Tmobile users and if it gets fixed with the MM update later this week.

S10+ loses LTE and drops signal constantly

I've been having my S10+ on Verizon which I got in March, constantly drop from 4G to 3G, to noG. I didn't have this problem with my S8+. It appears many other people that having the same problem with not only the S10+ but other S10s on other carriers as well. Supposedly Samsung is supposed to release a software fix, but Sprint is also having people return their S10+s and get replacements because supposedly many of the first ones made have a hardware issue causing this. Anyone on Verizon or other carriers having similar issues and any update on the fix software or return and get new phone or otherwise?

Sounds like the same problem I had on TELUS in Canada. Took it to Samsung and they told me they had to replace motherboard. Fought with them like cats and dogs and they refused to give me a new phone. After waiting over a month for them to fix it, I immediately sold it and bought a Huawei P30 Pro. Will never have another Samsung Phone after that fiasco...
Not sure. Supposedly the first few batches but I'm not sure of date ranges. All I know is this has been the worst reception of any phone I've had and it happens alll over. Drop LTE and if i hit Airplane mode on and then turn it off it comes back. In fact I just had to do that right now to reply.

I had drop LTE signal issue, sometimes lte won't come back until reboot the phone but after do a reset network settings my phone works significantly better:good:
Am having the same or similar issues my internet is working all fine and out of nowhere i loose internet while still having full signal bar. I tried airplane mode and nothing seems to bring back the internet only thing that works for me is a reset am on AT&T
This seems to effect all s10 models regardless of the carrier.
I have a Verizon s10 plus that I pre ordered.
My LTE will have poor speed and randomly not work even though the status bar shows a signal in spots with good Verizon coverage. I also noticed that my bluetooth will randomly disconnect from devices and is very glitchy. Also the battery life has been not great. Only about 5 hours SOT with lot of apps disabled and all settings adjusted for maximum battery life.
Also I noticed that if you go into settings/connections/mobile networks and observe the signal strength it is always either -120dbm 99asu or "not available" which is not good.
I Noticed the LTE issues after an update(not sure which one it was)
I tried Updating to the latest ASD9 and there is no improvement.
I did all the basic troubleshooting through verizon(new sim, provisioned the device again). No improvement
I reset the phone with no improvement, I flashed the factory firmware ASD7 with odin.... no improvement.
Finally I brought the phone to a local Samsung experience store.
They tried to run some tests but it would not complete them. They were well aware of the problems with sprint phones but were surprised to see these issues on a Verizon phone. Eventually they agreed to replace the motherboard but had an issue flashing the serial number to the new firmware so now finally im going to get a new phone. Fingers crossed, this has been such a headach
