Sudden Drop signal

In the past few days, I've noticed my phone sometimes loses signal randomly: the bars will turn dark gray (not light gray) and there would be an "x" over the bars. Def. no "3G" indicator.
And it's happening in places where I normally get signal. A reboot doesn't fix this. I just have to wait until the signal is back up. I haven't installed anything new recently, nor am I running anything out of the ordinary.
Anybody else experiencing this as well? I did a quick search and wasn't able to find much.
I'm still on 2.3.2 (haven't gotten the OTA), unrooted.

I also experience this loss of signal. Constantly. Every time during a call.

Just to clarify, this isn't happening to me during calls, or hasn't happened to me during a phone call yet. Sometimes I pick up my phone, and I see I have no signal. And of course, attempting to call out or access gmail/internet proves it so.
It's very frustrating.

2.3.3 comes with a updated radio.
You can also fastboot the updated radio but your phone isn't modded.

I will need to clarify myself too, I meant I always lose the data signal every time I'm in a call. As for the phone signal (bars), I have no issues.

Are you on EDGE (2G) or 3G or WiFi when that happens? EDGE does not support concurrent use of voice and data, but the other types of data should.

Has Anyone else experienced this?

hey guys,
I am running Brainmaster's final miui gb rom with the stock kernel and what I have been experiencing when trying any other kernel (francos, glagos etc..) is that my phone shows I have signal and it displays vodafone uk however I don't have a signal. I know this because if I then restart the phone say after an hour of recieving no texts etc.. I get all of my messages. This seems to be happening alot and when it happens I am unable to turn on airplane mode only a restart will do.
I am now back to stock kernel which didn't seem to have the same issue but I am now recieving texts 5-10 mins later which is unusual. Also I have data turned off always.
I have KF1 radio flashed and no radio dumps. My main issue is it displayed I have signal when I don't.
Was just wondering if anyone had experienced a similar issue?

Are Wifi Issues Hardware or Software Related?

Hi everyone,
I got my Nexus 10 a week and a half ago, and, for the most part, have been loving it. However, I've been having some annoying wifi issues. Every once in a while, the connection will go from 3-4 bars to no bars (but still connected) or disconnected completely. Sometimes this happens over and over in a short period of time (10-20 minutes), and sometimes it happens once and doesn't come back for a while. This happens on both my home's wifi and my university's wifi. I've been looking around the forums, and it seems like some other people are having similar issues. My question is: has it been determined whether this is a hardware or software issue? Should I RMA the device (I have a couple days left to do this)? Thanks!
Edit: I've also been running into problems with streaming video from YouTube and Netflix. It'll load the video fine for the first 5-10 minutes, but then it will stop to buffer every 5-10 seconds (in the YouTube app) or become low-resolution and pixelated (in Netflix). This also occurs on both my home and university WiFi, and both have download speeds of 15-20 Mbps. I've tried clearing the cache for both apps, which does nothing.

I'd say they are software, since I have more coverage of the wifi and I didnd't see any lose of signal, however on 4.2.1 I was losing the signal every 2 min or less.

Are you on 4.2.2 now? Do the WiFi drops persist after the update from 4.2.1?

Yeah, I'm on 4.2.2 as well, and I still have all sorts of WiFi problems. I'd like to get a little more info on this. Does anyone else still have WiFi dropouts on 4.2.2? And does anyone have any insight on the video streaming issues? It might just be due to my fluctuating WiFi connection, but I'm wondering if it is a separate issue.

I'm on 4.2.2 and my WiFi issues just started. It's driving me so crazy that I wiped and went to an older Rom with no luck. Hoping it might be my router so gonna try and test on another unit next.

I used to have wifi drops, and there is a couple large threads here already on this issue. But I managed to fix my wifi stability by changing router settings. I had the same thing of complete drops where the wifi disconnects completely every so often. It would happen at random, sometimes every 20-30 seconds, sometimes every couple minutes, other times 10-15 minutes between drops, a few times 3-4 hours between a dropout. It happens on other Android devices I own too though, so it isnt exactly a problem with the Nexus 10 exclusively. it took a LOT of work to finally find the settings that work, but I finally did it and now all Android devices I own are perfectly fine on wifi.

To be honest noone should have to change router settings, I have 3 Android phones,nexus 7, laptop and Xbox 360 connected all at the same time and still the only thing to lose a signal is this 10 inch slab. It's ridiculous.
Considering selling it already after 3 weeks.

Signal drops randomly (and frequently). Verizon.

I have a problem with my 6p where the signal just drops to nothing (Looking for service) and 3 or 4 seconds later it reconnects to a good LTE connection. The problem is not my connection as I live in a good area. I was rooted with xposed but for ****s and giggles I went back to complete stock and it is still happening.
I have reset the APN settings to no avail. Is this a thing that is known to this phone? Should I get a replacement? It started just recently it seems as I have had this phone since launch.
What sucks is, is that this phone is absolutely perfect (or was) and I dont want to get sent a phone with screen issues.
EDIT: I ended up getting an RMA and everything is hunky-dory.

What radio version are you on? You can flash a different version in fastboot and see if it helps.

Im on the newest one. Do I just extract it out of the 6.0 image file and just flash it over the top of the existing one?
I forgot to also mention that I tried getting a new SIM card from Verizon but that did not fix it either.

Yeah. Extract it and flash it over the top in fastboot.

Did you ever find a remedy for this problem? I'm having the same issues on t-mobile so its definitely not network or a similar related issue. Did flashing the radio from the 6.0.0 rom fix the issue? I already tried several different 6.0.1 radios and a radio from 7.0 but to no avail. I'm about to try it and if it doesn't work I'm getting rid of this phone.

I'm going to assume you mean you'll be on LTE for the longest time then all of a sudden signal completely drops then comes back on, but without the LTE signal showing near the bars, so you'll have to airplane mode, then switch mobile data on and off, then do a restart. If this is the case. That has been a documented CM13 issue for the longest time. I had the same issue with the HTC M8...

I am on LTE but as the OP said the signal randomly drops completely for 4-5 seconds them comes back LTE and all. I don't have to reboot or anything. This doesn't have to do with cm13 though, I've tried flashing back to full stock and I still have the problem there too.

Damn man...I have no idea - possibly radio like the guy above my post mentioned. Wish I were of better assistance.

I've managed to get a logcat at almost the exact time the signal drop happens, I had to put it in a Zip since the Txt document was too big for the thread. The drop happened in the last couple minutes. I'm hoping someone here with more experience than me can help me solve this issue. Thanks in advance.

Having the same issue on T-Mobile smh... it gets annoying at times!

Same problem here. On Verizon

Anyone find a fix? I'm on the latest Android N Beta on Tmobile and still have the issue.

Axon 7 signal issue

Hey guys, i got the A2017G model on B05 firmware and quite often when im in the building the receiver of my call only hears every second word that i say... Most of the time it loses the signal completely and stays with no signal for about hour... Reboot doesn't help... Can someone confirm if for example firmware b03 was better or if someone have same issue?
Thank you

I'm sorry, but I can only tell you that I had no receptions issues neither on B03 nor on B05. Both work just fine like my old LG G4.

Which firmware was overall better for you i saw some people roll back to B03

I am also having issues with the signal dropping on the A2017G.
I am using the official Nougat 7.0 update, but even on the previous version, I noticed that almost always after I make a call the signal gets lost and it takes an average of 2-3 minutes before it is restored.
Sometimes I need to turn airplane mode on and off and a few times I had to do a restart.
I tried changing the settings (e.g. only use 3g, or manually select my network) but nothing helps.
Do I have to go back to an older ROM or is there anything else I can try?
