Low Signal with Verizon - Nexus 6P Q&A, Help & Troubleshooting

Just wondering if anyone else was having issues with your Signal using the 6P on Verizon? Ever since I got it I've been lucky to get one bar on LTE! I switched it from global to the CDMA setting but that hasn't helped that I can notice, thanks!

Weak signal, poor reception, dropped calls

Anyone else having these issues? I've noticed that places I always had at least 1-2 bars with my note 2 I will not have any service with my note 3. Also I have been dropping calls in areas that I never did. Could this be my new sim card or should I exchange my phone? I also feel that my wifi connection stability/range is slightly worse than before.
Mine is the same way,don't get the signal my note 2 would and 4G is weaker also .

I hope this is just a first software or sim issue. Or at the very worst a first production run issue. I will likely be bringing mine to Verizon this weekend to test and new sim or exchange if that doesn't make any difference. Annoying.
Idk how much it will help you but I noticed I was in 3G a lot of the time as well. Definitely more than my N2, I switched my preferred network to LTE/CDMA instead of Global and I now have 4GLTE way more. As far as the wifi and phone reception, I myself haven't noticed any huge difference but I did read the international version of the N3 already received 2 updates and they supposedly not only improved the wifi and antenna signals but also battery life. Who knows when we'll see an update though. We are on Verizon.

Tried that and it actually made my signal significantly worse. I switched back to global and my problem seems way worse tonight than any day this week. Can barely hold onto a signal in places that I never had an issue before. Battery pull didn't help at all. I constantly get a message that says I can't send messages and then asks me to retry. Frustrating, will be going to Verizon tomorrow or Friday to return/exchange
Just now noticing this
I wonder if this has anything to do with being rooted? it seems like I just started dropping calls like crazy just today. I do remember getting the sent error on some text messages, though I can't remember if that started befor or after rooting.
Haven't had a single issue with signal or dropping calls. Also my 4G speeds are pretty insane. I'm thinking there are some units with defective radios.

Sprint Signal issues?

Just wondering if could be faulty unit or Sprint signal problems but i've been getting dropping signals randomly inside of my house, and also friend telling me that they called me but i never them calls, if more ppl like me?

I'm on Sprint JC and I've gotten slightly lower speeds in my living room than my Note 3 ,but still very solid 4G , But my city has strong Sprint LTE..
I've had no interruptions no sputters.

Do you think should I request an RMA for my phone? Or maybe is Sprint side

Just helped my girlfriend's mom with her new phone today (she's not had a smartphone before). I was very pleasantly surprised and happy for her that her phone registered 10-12 dBm better signal than my S6 (S6 and MXP both on Sprint right next to each other on the countertop).
Edit: I don't know that it would make a difference, but maybe just verify as an easy check, see if it is set to LTE. Her phone was initially set to Global, for some reason (it worked either way, but I didn't pay attention to signal before switching it to LTE).
I think Global is for aloud the phone to be selecting either LTE, 3G or 1x based on the signal, so if we switch to LTE only as soon I move to LTE ill be losing data

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

I bet 6.0.1 is at fault. Did you recently update OTA?

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.

Moto G4 4G LTE issue

Hello,
I bought the unlocked Moto G4 from best buy last week to use with ATT. I started the phone initially without any sim card in it. Next time i restarted i put in the sim card and it detected as att sim card and everything seems to work until when I notice that when i am in my office building I only see H and not 4G LTE. I had Nokia 640 earlier which was ATT go phone and i was getting 4G LTE on it in my office building. And I have also got LTE earlier on other phone in same building. I checked the APN settings and they looked ok since I am getting 4G LTE at most of the places. chatted/talked to ATT and they are of no help, they are saying that since its not ATT and unlocked phone, there is no guarantee that you will get lte everywhere and may be the antenna could be weak on the phone. But I am just not sure if I got a faulty piece or what. Since even the lower end lumia 640 was giving me lte in my office building. I am not sure if I should just return and get another piece or just return it for this issue.
Any help is much appreciated..
There are several good apps on Play that show you cell signal strengths and such. Do a search in Play for "cell signal info" and try one of those apps. It will at least give you a place to start and a comparison tool to compare phones.

I own a G3 and a Moto X Pure, I am on AT&T and have noticed the past few days LTE seems very... umm, weak I guess... at least in the Minneapolis/St Paul area, and my phone was falling back to HSPA+ way more often than "normal" this week (I travel here every week). I thought I was crazy but maybe there is more too it than that. I do know that AT&T has been doing lots of upgrades recently and rolling out LTE-A, or at least some kind of LTE upgrade, in some areas. Back home my LTE speeds consistenyl went from 20Mbps to 70Mbps down and 5Mbps to 25Mbps up in the last couple of weeks.
Best thing to do would be get a signal strength app, like LTE Discovery or Network Signal Info, and compare it to another phone on the same carrier in the same area and band (LTE Discovery will tell you the LTE Band you are using). Remember that not all phones report it the same, it can be wildly different, but it might give you some insight.
My point is, it may not be your hardware... and Moto's in general are known for really good signal reception. Just do some due diligence before returning it, but if you feel it is hardware, but all means exchange it.
thanks guys..will try it out..
Maybe I am being paranoid, but sometimes I wonder if cell carriers some how optimize their LTE signal to work better with their own phones. I have noticed this on T-Mobile when I always seem to get a stronger signal with a T-Mobile branded phone than with a third party unlocked device.

LOL... No, carriers have the ROM modified to make the icon show more bars on their subsidized phones. They can't actually throttle 3rd party phones on the same plan as a carrier branded ones, legally at least.

That's what I thought., although I still wonder why I usually get a better LTE signal with T-Mobile branded phones. This seems to be especially noticeable since I have upgraded to Marshmallow. Recently, I have or have owned a T-Mobile LG G4, an LG G3, an Axon Pro, and a Moto X Pure. As a rule I have noticed the signal strength being stronger on the T-Mobile branded phones.

Actual signal strength or the icon? LTE Discovery usually shows the truth...
Sent from my XT1575 using Tapatalk
This is based on readings from LTE Discovery, not the number of bars the phone is displaying. I suppose you could also come to the conclusion that LG phones have a stronger radio signal than other phones.
I'm having the same problem with both of my g4's in my area and seattle international airport... if it's not working there... then where will it work?

Yeah well I ended up keeping the phone. Someone else in the same building also reported lower quality signal with even Iphone and moto g4, all other areas we are getting lte so guess, i took my chances.

Using "nxtgenphone" APN? Sometimes LTE doesn't work unless you do

I ended up calling att and they provisioned my line for lte. Fixed both phones.

poor LTE connectivity?

Hi.
Is anyone else facing frequent call drops and poor LTE connectivity?
Any fix
Thanks guys
Not me. Works great on AT&T; I've been to several cities and suburban areas; no worries.
I have t mobile and live in king county Washington USA. Coverage is the worst in comparison to att or Verizon. But where there is coverage lte/LTE+/volte all work just fine.

No issues for me on Verizon in the SF Bay Area.
Straight Talk (tracfone sim...at&t) midwest, with the Ozark hills. No issues. VoLTE, LTE+ works fine.
I have TMobile in Gaston,sc I never drop unless screen goes off for a few I hot airplane mode the back to full when I turn it off
Thanks guys. Seems like a carrier issue for me then. But there are Oneplus forums filled with users complaining about the LTE connectivity. Dunno who is to be blamed.
Anyways, thank you for your time.
