Radio Drops [Log Attached] - Nexus 6P Q&A, Help & Troubleshooting

I've heard of people having these issues a lot before but never ran into it myself.
I just got my replacement Nexus 6P setup. Flashed all the factory images, the systemless root boot.img and SuperSu 2.56 -- exactly the same as my old device.
Only now for some reason my cellular radio drops all the time, it especially seems to happen when I start using it after idling for a bit. It cuts out, goes to the hollow bars on the signal, then slowly comes back on and connects to LTE.
Any idea why this is happening? What I can do to troubleshoot or fix it?

I've captured logs from where I'm pretty sure the drop begins and recovers. Anyone?

G2 radio issues......

How wide spread are these issues. I'm on my 3rd phone now and a side from an annoying dead pixel my phone still fades in and out while on voice calls to the point where I can't even catch a full conversation sometimes. Also drops calls.
The OTA did not help the problem one bit.
Is this something that will be/could be fine tuned? I've read the nexus never had a good radio compared to "other" phones.
As much as I like this g2 I can't have the poor voice quality issues.

For me, the radio got a tad better after the ota. I still get **** reception at home, but now it seems like it doesn't drop signal like before, but then again, I just installed the ota and rooted last night on the stock rom.

I got lucky the first time through, my hinge was pretty tight, i had 3.2 gb free space in my phone, and had one one minor antenna issue. Once a week or so I would drive somewhere and when I would look at my phone i would have an X and no bars. Only way to fix it was to restart, since it only happened once a week i didnt really bother with it. The OTA Fixed that problem so im just very lucky this phone around
ps: jk about the 3.2 gb, i got around 1.3 gb like everyone else
I am still seeing radio issues after the OTA. By switching it to airplane mode, then back to non-airplane mode (versus a rdeboot), the issue is temporarily resolved. Makes me think its a s/w issue with the radio. During the initial release I had to reboot to get a lock on GPS (a few times).
Hoping cell reception gets fixed in an upcoming OTA. Sucks having worst reception than my G1. Until then, wifi calling is saving the day at my house.
The only thing we can do is keep complaining and hope they listen.

Sounds like it might not be a specific phone issue.
I really want to keep this phone but the radio is unacceptable! My wife's BB gets 3g throughout the house, and not only that she can talk on it without issues....

Same with me for the most part. I just did the airplane mode trick, and it's the first time I've had to since the OTA. I have had the data drop plenty of times since the OTA, but after a few seconds it would come back again. The OTA was supposed to address this radio recovery problem, but clearly it didn't fix everything. I think I'm going to call customer service again and let them know.
On a side note I believe the issue I had today was with the XP tether driver. I think it's rather buggy as it tends to get stuck connected regardless if there is a phone tethered to the computer, and I have to restart! I still have had the data connection drop since OTA, but it usually fixes itself.

Count me in. I'm on T-Mobile us. I upgraded to nexus a week or so ago from HTC hd2. I had almost full bar on my reception most of the time. Some times it might dropped down by a bar or 2. Ever since I used the nexus s, my phone is only stayed at 1 bar 95% of the time. I'm testing this all in one room and a particular part of the room because I'm there most of the time when I'm home. Anyone got a reason or fix? I've had one instance that someone called me 6 times in a row and the call never went through. After I found out, I tried making calls and the call features locked up. So I rebooted the phone and it went back normal.

Ya and also the wifi bar goes down and my x10 gets full bar

I've had similar experiences with the Galaxy S and the Vibrant I had before. Maybe it's a Samsung issue....
Sometimes I have full bars, but when I try to make a call it attempts to ring, then it fails and it just goes to locked screen. It can be really frustrating.
Mine is stock, not even rooted.
im also running rogers nexus s stock and keep having issue with reception bar and wifi bar . anyone? know whts wrong anyone?
same here, i go from 4 solid bars to 1 all of my data based apps disconnect (tunein/maps) then it takes about 5 seconds to get everything back. i know theres been consistent radio issues with this phone but im not too familiar with the specific

What are sns_async_ev_wakelock, sns_periodic_wakelock, and main?

These 3 wakelocks are always about even with each other at anywhere from 50% to 90% of the time "since last unplugged". Anyone know what these are, if they're normal, or how to get rid of them?
turn off latitude helps a lot
but they are Android 4.2 bug, i think Google will fix them
Probably normal if you were on the phone or doing lots of texting.

Hmm they're actually increasing almost the whole time the phone is idle with screen off though. Latitude is off as well. I'll try a clean ROM flash after factory reset and report back. Thanks guys.

Unfortunately these are still present (and high) after a full wipe and flash of the latest AOKP. Anyone else see these at the top of your wakelock list?
Not on MINCO
I am having this issue too, I believe it might be an AOKP problem:

Well, I searched for hours, and hours for this wakelock too, and I think I finally found what it is, basically this wakelock is caused by the signal processor going berserk and waking up your phone constantly, most of the time this is caused by something disturbing it, and in that you have to think about something that could change or capture a signal in really the root and not through the official Android ways, like Viper4Android, it changes the audio kernel, this could disturb it, or automatic call recorder, this one picks out the voice signal, and this applies to almost all the sensors and signal processors

[Q] Constant signal loss

This seems to be an occurring issue for me everyday while using my Nexus 4. I would lose signal completely, and it would not ever find signal again, unless I switch airplane mode on and off really quickly. This happens when I'm at school, in certain classrooms. It's weird because on my old phone, I would get 2-full bars anywhere in the school (I'm on AT&T and have been for years). Any ideas on how to fix this?
I'm running PA 3.10 4.2.2 with Trinity Kernel, if that helps.
Thanks!
Try a different sim card of the same provider. Usually sims. Us be exchanged every 3-4 years.
They are vulnerable to ESD and poems occur if they have been bent.
Good luck

Im on my third sim and I still get this. Constantly losing signal and other phones with the same provider which is tmobile don't have this problem. I was hoping the update would fix this but it hasn't. I might have to rma as I can only think it is a hardware issue

Random reboots and lag

Got my T-Mobile black onyx S7 edge the other day. Love the phone and my wife has one as well. We have both had a few random reboots and lag where the phone gets very hot afterwards. Has anyone else been having this issue?

Nope. Been running mine for three days now, and not a single freeze, reboot, or any overheatng for that matter.

I did have one random reboot on initial setup. After that, the phone has been fine.
No random reboots but I did have one glitch that I have never seen before. I did a test call to my house. I hung up and then the my cell phone started ringing again followed by my house phone ringing again. It placed a call to my house again but there was no indication of the active call on my cell phone except for the audio was there. I could not hang up the call on the cell phone since it wasn't showing any active call. I had to hang up my house phone and everything was good after that. It was very strange and only happened once.

I have had 0 problems - love this phone - if you are still having lag and random reboots, maybe a "Factory Data Reset" would help?

I had a couple instances of lag/hang up the first couple days of use, but it's been smooth sailing since. Probably just needed time to settle in a little more.
No reboots here. But there are numerous hiccups I've had with various apps and such. Nexus 6P still takes the cake as for as smoothness and stability in my experiences.

Only thing I have noticed is when enabled, the 'Game Launcher' feature tends to make my games lag. I'm not quite sure what the purpose of the 'Game Launcher' feature is (I thought it was meant to provide a smoother, less-interrupted experience when in games) but it seems to be causing more harm than good.
Once disabled, all my games are back to running nice and smooth. I am assuming a software update can and will fix this, as it is a relatively new feature so there are bound to be some bugs, but I was wondering if anyone else has experienced this as well?
Other than games and the 'game launcher' issue, I haven't experience any other lag once I got past the first couple of days.
I had a comparative issue when I first got my Droid turbo 2, it was rebooting a considerable measure. Like 3 times each day. I wound up exchanging the console programming out, uprooting and incapacitating all the superfluous programming the telephone accompanied and after that the issues ceased. Telephone has rebooted subsequent to.
what i do right off the bat is update any software updates there might be then factory reset it through recovery. a clean start to a new device

So after having the phone for a few days now. Looks like that might have been a one time thing upon initial setup as the phone has been running great ever since. Looks like I jumped the gun. My last Samsung phone was the galaxy s2 on Sprint. That phone was so buggy I guess I was a bit to quick to judge Samsung based on a very old comparison.

I had this too. 100% fixed it by performing factory reset via stock recovery.
You are getting lag and reboots because a Samsung security update patch was failing. Only way to fix is factory reset
