I've been really interested in finding the cause of these reboots and bootloops that are affecting many people. Right out of the box, the tablet does 2 updates and somewhere things go south. The tablet starts rebooting at random intervals which can lead to further errors and bootloops.
Knowing a thing about Nexii devices, several people now have working tabs. The trick is reflashing the stock image or a CM rom.
My conclusion is that a big batch must have been flashed with a bad stock image. It takes a little know-how to manually reflash stock, but there are 1-Clicker PC apps that make it easier.
Anyone wanna write a little batch file that JUST automates reflashing stock image?
Also for those with rebooting or bootlooping N7s, just factory wiping isn't the fix because the files you are restoring are bad. People are wiping over and over with no better results.
Hope this info helps and I'll try to elaborate with some steps and links. The information is on XDA already, probably to some effect of such a title like "Stock Images".

Perhaps you can compare the checksums for all the files in the bad /system against the good /system using some scripts?
An interesting project, and more than Google/ASUS are (apparently) doing for us.
I'll help in any way I can...
I have no problems believing Google will patch this soon, but in the mean time people have rebooting Nexus 7s and eventually it will go into a bootloop which requires a wipe to fix.
If someone could make a quick little PC script to grab the stock and automate the fastboot flash commands. Just a temporarily permanent solution until Google patches it.
The problem is most people using stock probably don't realize it is rebooting. Mine would reboot when idle and I'd never know unless I checked uptime. So people are grabbing their tabs and finding it off because it rebooted, corrupted, bootloops, and runs till the battery dies.
Anyone using straight stock should check their uptime status in Settings. If your Uptime looks low, it is probably rebooting in the night or when idle. If you do nothing, you risk losing your data.
Its best to backup your data files, wipe, flash a stock image, and restore your data.

If you are talking about the random reboots, for most people, that isn't about corrupted images. I thought you were talking about some bootloop problem.
Corrupted user data from those random reboots is a possibility which maybe is what you are saying, but that will only get fixed if you fix the random reboots, which I don't believe are caused by corrupted factory images for most people.
Anyway if it really is about bad factory images, one should be able to compare good and bad and isolate the differences.
If the differences can't be located then it puts to doubt whether the theory is correct or whether one isn't looking in the right places.

That's exactly what I'm saying. Bad images = reboots = bootloops = wipes = loss of data.
When it reboots 6 times a day, corrupted userdata is going to happen eventually.
I don't really care about "why" as much as just helping people find a solution to fix it while Google makes with a fix. The ONLY thing that fixes the reboot issue is to reflash the stock image. I'm just sharing my findings. This is what I did and with my suggestions, several others are finding success at fixing the reboots.
This fixes the reboots. Which fixes the random bootloops.

Put it this way, I've reflashed stock images from google published tgz file many times and never gotten rid of random reboots. They eventually come back if I use Chrome. If I don't use Chrome the reboots go away. This is for MY usage pattern. Chrome may not be a trigger for everyone and likely isn't even the root cause, however I have flashed the stock images and still get random reboots.
In over 3 weeks of folks experiencing random reboots, I doubt I am the only person to have flashed the stock images and still have been able to reproduce random reboots.
Personally I like to investigate and understand why something fixes a problem. I like to understand why some procedure would fix for one person but not the next.
I would suggest flashing a CM rom. Test. Then flash back to stock. Test.
Somewhere, something gets fixed.
I also found Next Browser. Its based off Android Browser and much faster with great swipe options. I have been using both simultaneously though without fail... but chrome is going to be uninstalled here soon. Unless you need Chrome for specific purposes, its much slower then others.

FWIW running cm10.2 nightlies and only reboots are those I intentionally do to load up a new nightly. CM's so much better than stock.

It's unlikely that the stock factory image is the cause of random reboots.
I've flash cm10.2 nightly on mine and it still reboots every 20 minutes whenever WIFI is turned on.

Hold off for the JSS15Q update which may improve your situations...granted its for the multitouch fix but they are reporting it may fix bootlooping, albeit sacrificing custom ROMs and root temporarily. All current ROMs use the (buggy) JSS15J firmware base so when Q hits it may be the fix needed. On another note I doubt it's bad factory images, I've only had 1 random reboot in the 10 days I've had my Nexus 7. That, granted, was a bootloop which I had to factory reset for but it hasn't happened again (touch wood.)
Yeah, this hopefully all disappears after today.
If you use stock and keep track of your uptime, you might notice your N7 is rebooting quite often. I never noticed it until I found the reboot thread, and checked. It said the uptime was like 5hrs but was on all day and night (I was working). I checked again in the morning and it had a 2 hr uptime. This went on for a while. I never actually caught it reboot. It would champ through games and hours of use with no problems, then reboot when idle.
The bootloop you had was probably from the reboot issue. It reboots frequent enough and shuts down during cleanup and corrupts user data.
I've been running CM and no reboot issues/bootloops at all. So whatever it is, it is with the stock rom. Thankfully this patch is sooner then later and hopefully fixes the Multitouch AND the reboots. I think the bootloops are the result of the resets.

Surprisingly no, I used Reboot Logger and there were no random reboots after I did the factory reset, the uptime was continuous, since the bootloop and factory wipe no reboots were logged (that was 5 days ago).

So this morning I got a call from a friend who told me that his TF is running like crap after doing OTA upgrade to ICS.
We met up at school and I got to take a look at it. Yes, it was indeed running like crap and it even randomly rebooted while we were eating breakfast. He told me the random reboots were happening every 3-5 hours(that he could notice).
Here's what I did to fix it.
Removed his MicroSD card(not sure if necessary)
Shut down TF.
Hold [volume down] and [power] button together until you get into reset mode with 2 icons in the center of screen. Left icon is Wipe Data. Right icon is Cold boot. Right icon is selected by default.
Press [volume down] to highlight the LEFT ICON, which is Wipe Data.
Press [volume up] to confirm your selection
Go through the process.
Let your TF reboot.
Shut down TF again.
Hold [volume down] and [power] button together until you get into reset mode with 2 icons in the center of screen.
You need to do cold boot. It's already selected by default so just wait like 10 seconds and it will happen automatically. Press [volume up] if you don't want to wait.
Go through the process. Your TF will reboot afterwards.
Done.
It has been over 24 hours and his TF has been running smooth without any glitches or any random reboot. I told him to let me know immediately if a random reboot happens again.
This is simple to do. Worth trying unless you can't read English.
Edit: I didn't include this at first because I thought it would be common sense for everyone but it apparently isn't....
DO NOT JUST RESTORE ALL YOUR PREVIOUS APPS AND WIDGETS YOU HAD FROM HONEYCOMB. THAT DEFEATS THE ENTIRE PURPOSE OF DOING A RESET AND PREVENTING APP INCOMPATIBILITY.
thnx man for sharing . I actually tried every thing to solve this issue but no luck , I'll try your as sson as i go home .
This did indeed work for me as well. I tried this a couple days ago and I have yet to have any freezes or random reboots. I think that not restoring any backed up data, apps or settings is key to fixing the problem. I'm now very happy with ICS- burn in hell Honeycomb.
Shameful bump
When you switch from a version like HC. This is what you exactly should do!
I did this and never experienced random reboots.
My Transformer is running since three days and everything works fine!
Edit:
Another quick hint:
If you want to work with Google Docs, you have to disable Forced Hardware Rendering!
I see on forum the problem is google+

.....lol, why post in this thread that you are not going to follow the advice of the Op?.......
Sorry to say but this is not working, already done this since the minute it was out and still have so now and then a hang boot
(random reboots that hangs on the boot)
Giving it a try
I am experiencing random reboots after ICS
Wiped transformer, cold booted, and installed the following.
Adobe Reader
Dog Catcher
updated G+ and GMail but have not run it.
Charging now, I will let you know.
Previously I had wiped it and reinstalled all, disabled syncing, disabled location info, adjusted wi-fi settings, and added CPU throttle control obviously none worked.
It might have helped some people, but it did not help me. Unless it was dogcatcher.
5 or so minutes after unhooking it from the charger, I tried to wake it. And it was unresponsive. Was only able to wake it by holding down the vol down and power button at the same time.
I will kill off Dogcatcher and try again but it is not looking so good.

why are you installing dogcatcher? And this does work.. do it again. Don't install your apps.enusre it dos not lock up before you install anything.... If it locks up before you install any apps then call Asus. If not start installing one app at a time. Wait after each install. Ensure that its not doing it, once you are sure install Another ....rinse/repeat....
I installed dogcatcher because I needed something to listen to on the way in to work. I have uninstalled it. But I doubt that is the issue.
I have had these sorts of reboots on my Transformer until the third or fourth Honeycomb update. But eventually they fixed it. I suspected this would happen again.
Considering that dogcatcher one of the most popular podcast apps on the market I suspect that there are many people with no problems using it just fine.
But since I need a podcast listener to be able to use the device as I want to, does anyone without issues have a podcast listener that they use?
2 hours into the last experiment and it died again while sleeping.
So that about sums it up. This procedure might help with some issues Transformer's are having but not all.
Recap. Wiped, cold booted, gmail setup, G+ updated still equals failure.
I love how horndroid 'solved' this issue and then goes on the belittle people who are still having it as 'stupid', and probably their own fault. Horndroid, I appreciate your attempt to contribute, but your attitude and stabbing-in-the-dark protocol is not becoming nor helpful to anyone. Definitive statements pertaining to ONE TF101 device that you own are quite naive, there are several different models, and until you have personal access to each model version you should advertise your 'solutions' as "worked for ME", and understand if it doesn't work with others it isn't THEIR fault..this is not a blanket solution for every device's reboot problems. In fact, I am willing to bet the reboots being resolved by this method are of an entirely different genesis than the reboots that I and others are experiencing (hang-boots).
I hear what you are saying I have the reboot issue as well.
I did a reset before and after and only installed xda HD and ran it for 2 days and got 3 reboots so I did the cold boot and then it did it 2 more times that day. Earlier today I almost couldn't get out of the boot loop, so I wouldn't say its a app problem its something wrong with the firmware somewhere

Some aren't too lazy we just don't want to wipe data after every update. I think i have gotten 4? OTA updates and 2 of them screwed up deep sleep while docked. Guess what the first trouble shooting step was...wipe data. Guess what worked...the next OTA. I don't have time to read through all the different threads on the same subject but are people that flashed through cmw instead of ota having the same issue? My buddy went this route and has no issues.

Can't read horndroid's "advice", because I have him on ignore for trolling, and have done for ages. From the tone of other posts here, it seems the "solution" is to wipe; if that's actually the case, it's total BS.
I wiped immediately before upgrading to ICS, wiped again afterwards, and have put almost no programs back on. I am and always have been on stock firmware and unrooted. I had no problems with boot loops, no problems with lockups, and only extremely rare problems with spontaneous reboots using Honeycomb. With ICS, I have had all three problems in a matter of days, and the lockups / spontaneous reboots are fairly regular (1-2 times per day.)
This is a problem with the stock rom, not a user app problem.

I reported him for verbal abuse and foul language. His attitude is not helpful, and if I were a mod he'd be gone already to think long and hard about his conduct. Anyways, taken your advice and blocked him. It is obviously an issue with the ROM, I'm beginning to think it has something to do with deep sleep, others posited that it may be media scanner, maybe combination of both? Maybe these two events are trying to happen at once and it doesn't like it.. a stab in the dark at least..

It's hilarious how you think YOUR problem is the only problem that everyone is experiencing.
For a lot of people, it was the app incompatibility that was causing them issues.
Obviously you think your problems are caused by something different, but that doesn't mean there are different problems caused by other reasons.
While all of you are speculating, at least I've posted a solution(even though it's merely doing a data wipe and cold boot, pretty much common sense) that has been proven to work for a lot of people. I've never claimed it will work for everyone; just those having problems due to app incompatibility.
I'm pretty sure this is an issue with the update itself and all these "fixes" are going to be pointless in a little while when an actual fix is released by Asus.
When I see all these posts about problems, I honestly can not relate at all because my TF101 with ICS literally has no problems at all. I've downloaded about 30 apps so far.
Other people who say they have no problems also usually mention that they did a factory reset before upgrading to ICS.
Just a coincidence?
I did and haven't had as many issues as others....some tho - tearing when expanding the recent app list, some random app crashes that I'm blaming on the apps....I did have a reboot cycle yesterday after waking up on battery from the dock...a cold boot remedied that.....other than that it's been a good update....
mines running smooooth as well, I did a full wipe so doing a factory rest didnt make sense to me. I'm running AR HD..
No factory reset for me and I'm good so far.. well I just got it back from Asus, I think they might have done one lol

full wipe does what factory reset does plus more.... so you did do factory reset. Can't believe you are taking it that literally.

Nope. And I upgraded directly from a custom ROM.
100+ apps installed before the upgrade and running great afterwards: no random reboots, battery draining or app crashing. The only issue I have is with Chrome occasionally locking up. However I attribute that to its BETA status.

Perhaps ... perhaps not. A problem-free ICS upgrade, however, is not the sole provenance of those who factory reset/full wipe.
--L.
I did a full wipe when updating to ICS. Was fine for the first few days and now I have reboots/shutdowns maybe once a day. I had battery drain once as well. Its actually been pretty good other than that but I have kept it pretty standard with only a few apps as I am waiting for some better ROMS to come out with fixes.

I did not wipe or factory reset. Have had one LOD 3 hours into sleep mode, one boot loop when I pulled out the SD card and one spontaneous reboot soon after coming out of sleep mode and rotating from landscape to portrait. Have had various Google app issues that are working themselves out.
I was prepared to wipe after I took the OTA, but haven't because I have had zero issues. I use my tf101 everyday, and it hasn't locked up or randomly rebooted once. I have about 60 apps installed.
Nope. I just hit update.
I've had the weird shutdown during sleep only once since first day update was available for USA.

I only had an error that Android media closed out something like that for the first few days after update.
Clearing caches in my music apps seemed to work at first. Now that is back and my tf had been shutting down while in sleep. Just put it down to sleep for about 20 mins came back to Android logo on the screen with the circle froze.
It seems like this is getting worse for mine. tried everything but a wipe. Stock has not been rooted.
have always been on stock since the beginning. Never had any major issues. Was considering rooting to get cornerstone when it is stable.
Until than what other options can fix the reboots.
For some reason on honeycomb downloading something or the honeycomb status bar would always flash and mess up. I downloaded lots of stuff and tweaked it so that might be why. I wiped after coming from revolver and went to stock ICS. When it updated it was crazy slow and laggy. After every app was restored from the market I reset it and it FLEW. It just flies in terms of speed.
When I did my titanium restore I restored EVERYTHING. Not just apps but system data as well. When I did that I noticed it was slower and laggy and that notifications and download gitch was present.
I did factory reset again and only restored the app data this time and it's perfect now. No more lag or anything. Titanium back ups are fine and everything but if you were currently having lag or weird problems restoring the system settings doesn't help. I did not need them anyways. I love ICS. I really love how we get the status/notification bar that the prime has. Also the sony tablet and other tablets now have the little box markers at the top which let you know what page you are on. I'm glad we get that now as part of ICS too.
Factory reset definitely helps. Also I got to see that cool droid restoration image when it was resetting everything. I have never seen that before and it looked awesome.
no factory reset, Everything working good
This thread is complete nonsense, and to prove it, I have two TF101 tablets here. One was wiped before *and* after the ICS update, and had almost nothing reinstalled on it. The other was not wiped before *or* after. There are pretty-much no programs installed in common on both. Both are experiencing random, spontaneous reboots. Both are experiencing lockups. I've yet to see a boot loop on the one that wasn't wiped, but that's just chance -- I'm quite certain if I left it long enough, it would boot loop too, just like the one that was wiped.
horndroid loves to try and suggest this is somehow a user problem, but it's not. It's a fundamental problem of the stock Asus ICS ROM.
My result;
Normal upgrade from HC to ICS = strange behauvor and reboots.
Factory reset and upgrade to ICS = works like a dream, no big complains...
After ICS I have notice that some times ( one or maybe two times a day) screen is flash /flickering - but only for a micro second. Statusbar sometimes flickering when open, but not a big deal...
I have about 200 apps installede, many from 2 parts Market ( read Aptoide)

So i hope this anticipated fix which ASUS is rolling out NW fixes the probs-- Hum!! I seem to recall being called out as spreading rumors in another thread about the ASUS fix. - Well like i said the fix is on its way.
No wipe from rooted stock ... the odd second of screen flicker when running onskreen but nothing to cry about. All good really
My EEE Pad was running like **** (i.e. sleep of death, rapid drain, huge lag, random reboot) I have upgraded from stock 3.2 without performing factory reset.
I tried cold boot and that did not help anything.
So I took the plunge and did full wipe + cold boot. So far have not had a single issue. Just FYI.
Mine actually appears to be getting worse and worse, quickly. The stock apps are going o pieces. Google Maps repeatably crashes if I zoom in beyond a certain level, or if I enable the satellite view layer. Gmail is near-unusable -- email counts are frequently incorrect, or are correct but new emails that are visible through a web browser don't show up when you reload in the app, the app repeatably crashes when I click on certain email threads to view them, and randomly crashes at other times, sometimes within seconds of opening the app in the first place. Google Reader likewise often locks up, doesn't mark posts as read when you click on them, doesn't reload posts correctly, etc.
It's *only* the Google apps that are misbehaving; well, other than the OS itself regularly, randomly rebooting, freezing, or getting stuck in boot loops, this is.
And this is all on a stock, unrooted TF101 that has relatively few apps installed, and was wiped both before and after the ICS update.
Looks like when this new patch arrives, I'll be wiping and starting from scratch yet again, in the hopes of resolving this mess.
I have done countless searches and tried everything I possibly could to find a solution to my problem and nothing has worked.
When running any 4.4 rom, and I have tried pretty much all of them, I have this wifi issue. The problem is that if I have wifi turned on the phone starts randomly rebooting approximately every 15-20 minutes when the screen is off. I have tried every setting, upgraded and reset my router(dd-wrt) with different settings and a static ip, and tried different apps that are supposed to help with wifi issues.
This does not happen on stock roms and I have zero issues with any other devices on my network. The very limited amount of info any where that I have found with a similar problem all lead to dead ends. This happens regardless of being a fresh install with no apps installed besides gapps. I really just can not think of anything else to try. Please help me with my G2, I really want to like this phone. :crying:
From the complete lack of info I am able to find on this it would seem to be quite a rare problem. But if anyone has any suggestions for me I would really appreciate it.
No suggestions at all?
Mine is doing this too, however not as frequently. Are you using a proxy app? And do you have auto-wifi disconnect on?
It has nothing to do with the router. I'm 99.9% sure it's either a rogue app or a bad install.

No I'm not using any proxy apps or disconnect. It's not an app or bad install as far as I know. Like I have said this has happened with every install of any 4.4 rom that I have tried. Including, PA, CM and Mahdi. When installing any rom I always do a full wipe, cache, data, dalvik and system. Even without out installing anything besides gapps it happens. So I think I can rule out a rogue app or a bad install.
I have reinstalled countless times and it always pops up. On occasion there has been instances where the problem does not start for several hours after a fresh install but invariably the issue does come up and the reboots start again every 15-20 minutes when the screen is off.
I mentioned the router because, although rare, they can cause issues with connecting devices. Most of the problems that I have read about is usually the other way around though. The router crashing with certain devices connecting to them. But I have had zero issues with my router and any other devices but still thinking it could be possible.
I have a 4.2 rom(Energy) installed currently with no issues whatsoever. It is only KItKat that seems to be a problem. I just have no idea what it could be.
What model is your g2 and kernel? The only thing I can think of is you are changing sleep tweaks on the kernel and causing it to sod when in deep sleep. Are you undervolting?

Make a backup and wipe everything, and boot up into a totally clean rom WITHOUT installing Gapps for it. Then see if it keeps happening. I'm searching around and not really finding anything on this issue. Mine hasn't been doing it since I flashed the new AOSB build

Well I took your advice. I wiped everything and did a fresh install, latest PA without gapps.The only thing that I have done is connected it to my wifi. I let it go for about 3 hours and had no reboots. So I installed Banks Core gapps. Again, I let it sit for 3 hours. No reboots. All the while it has been plugged in and charging. As I write this, I just unplugged it from the charger and within 2 minutes had my first reboot. We'll see if they continue.
So now, I wiped and reinstalled PA without gapps. I did not install anything else at all. Turned on wifi and started getting at least 2 reboots per hour without even using the phone at all. When I turned off the wifi it has been running for 10 hours now without any reboots at all. I am at a complete loss as to what could be the problem. Is there anything I can do?

I hate to say it, but I'm at a loss too. Best course of action I can see is for you to return to stock, email LG, and ask for a replacement for a defective device.
Hi,
My Nexus 7 2012 (very first batch) is quite often behaving really slowly. It is common for the settings screen to take 15-20 seconds to open. From the homescreen. With no running app.
Here is a video after I've reset everything to factory defaults, let it run and index things on its own for an hour and then manually upgrade a small app:
At other times, the speed is pretty decent for such a tablet. I just can't figure out why this difference. I've tried to check for wakelocks, tried a logcat and many other things. I can't make any sense from it.
Rebooting the tablet seems to have 50% chance of fixing the problem. So it's probably not a memory leak.
The tablet is rooted, on the latest build and I noticed that App Ops X survived the reset but no funky software is installed and the behaviour predates the installation of App Ops X. The network is not a problem here. The 2013 Nexus 7 of my wife works just fine and so does the Nexus 5 taking the above video.
How can I investigate this ? Is there an app that can run various reliable diagnostics to find out what kind of activity is causing trouble ? I tried to use logcat but the result is quite verbose and nothing rings a bell. I would really like to understand rather than just return it and wait or, worse, buy a new device.
Thanks.
Let me know if you find a solution my Nexus 7 has been really slow, Im rooted with CM11 M6 & KK GAPPS, TWRP 2.7.0.0 I dont know what happened to this tablet.

Mine too. Nexus 7 2012 16GB running PA 3.99 (JB4.3). PA Kernel and GAPPS, PA launcher or whatever one came with stock PA.
It takes upwards of 10 seconds to unlock frequently, even from a fresh boot, and without any security just a simple swipe unlock.
App drawer can take 10-15 seconds to open.
If I touch too much during these lag times I will often get a launcher not responding error.
I've about given up myself and am looking at other ROMs. Before I reflash though I may try a different kernel.
I'm downloading a few right now and I'll hopefully remember to report back my results.
Mine is suddenly unbearably slow too. It's a 2012 edition and I'm not rooted, running the stock software. I've tried clearing caches (app and system), doing a factory reset, flashing the factory image, but it just runs like a dog. When I switch it on it takes a few minutes to become responsive, and apps regularly say they will take upwards of 20 minutes to download updates - small apps too, about 3MB. The download issues are nothing to do with my wifi as the tablet is slow wherever I use it, and my Nexus 5 downloads the same things in a matter of seconds. Would love to know what I could do to fix my N7. I don't want to root it or flash a custom ROM - don't want to go down that route - I just want the great performance that I had from it before.
I was having the same issues described here as well after owning the tablet for awhile, and tried every custom ROM, kernel, and android version I could find for our device along the way, in the hopes of finding a solution.
The one thing that finally helped for me, was formatting the device to use F2FS file system format on all partitions. The initial setup is a bit tedious, as you will lose ALL data on the device, so first must back up everything, then restore it all once the device has been reformatted. But the payoff has been huge for both me and my wife.
Making this switch has made both of our tablets usable again, even enjoyable! It's well worth the effort put in to make the switch.
See this thread here http://forum.xda-developers.com/showthread.php?t=2678140, which has the modified recovery, files, and instructions needed to convert. It also helps to first make sure you can successfully use fastboot/ADB commands from your PC to the device, in case you get into any trouble along the way.
There's also an app now available for converting any rom to all-f2fs (prior to flashing), it's cheap and well worth the cost (about the price of a cup of coffee) https://play.google.com/store/apps/details?id=com.runnerway.converttof2fs&hl=en.
Just got this today and it's great besides being a bit smaller than my g6 and because of front camera design only being technically 5.5in screen for most apps especially games.
However since I have had it, it has randomly rebooted itself twice for no real apparent reason. Is this a known issue or something anyone else has experienced? I want to try to get a bit more information on it before contacting the eBay seller. It is a refurbished.
I have never experienced a random reboot. You might want to try factory resetting your phone and then setting it up with the fresh start option instead of restoring from a Google cloud backup. Was your phone on Nougat or Oreo when you received it? Were there any major software updates?
It was fully updated to 8.1.0 when I received it. April 5th security patch. It was factory reset and I started fresh. No backup other than logging into my Google account for contacts, passwords and logins and such. I never do backups and restores always start fresh other than Google account.

Must be rogue app, had mine 3 months and never had a glitch or reboot.

If you are still having the random reboots you might want to boot your phone into safe mode to verify that a third party app isn't causing the problem. Since your phone was refurbished it's also possible that it was damaged by the previous owner or returned for the same issue you are experiencing. I did read that some early PH-1 buyers had to return their phones because of hardware issues like overheating.
Just did it again while using chrome. Just froze up for a few seconds and restarted. Doesn't seem to be overheating and the first time it happened before I installed anything I think. Guess I'll try a reset and go from there.
Factory reset twice now. No 3rd party apps installed. Updated all apps on Google play. The default phone apps.
Now the phone is freezing and rebooting itself constantly. Out of control. I am in safe mode right now and hasn't frozen yet. I don't know what the hell is going on.
Would love to be able to fix this issue myself without having to do return shipping. I have contacted the seller already though.
If it doesn't freeze or reboot at all in safe mode that usually means an app that you downloaded is causing the problem. The normal thing to try would be to factory reset the phone, download one app and see if there are problems. If the phone seems to be fine download a second app and use the phone long enough to see if the phone is stable. If it seems fine download a third app and do the same.
That's obviously very time consuming and if you were running a phone with heavily modded code like OnePlus with Oxygen it would probably be worth the investment of time. But this phone runs stock Android. Unless you are installing something unusual that might cause stability issues what you are describing sounds like a hardware problem. You might have bad memory for example and not enough is going on when the phone is in safe mode to trigger the unstable behavior.
I think returning or exchanging the phone you bought is definitely your best course of action. I really like this phone but it sounds like yours is defective or damaged.
The only other thing that comes to mind is that sometimes if you own more than one phone the Play Store will show apps that aren't compatible with the phone you are actually using. Dialers, messaging apps, camera apps and music players made for a specific phone brand aren't usually compatible with other brands because they need modded framework to function properly. Some apps that definitely are not compatible with this phone do show up in my Play Store Library available for download. Is it possible you are downloading an incompatible app?
I factory reset and haven't installed a single app. Just updated everything that was stock with the phone after reset. I was thinking faulty ram too, seems like it is.
Yeah I guess it's toast. Last night while watching YouTube it froze. Screen scrambled with artifacts and the phone made a loud continuous howling sound like an emergency alert. I honestly thought it was an emergency alert until I saw the artifacting.
Unless someone here can possibly give me an idea of any other reason it could be displaying this behavior I guess I have no choice but to return it?

Grab a BTS zip from the back to stock thread... And flash that...
I'll bet however it was updated had some yuck in it...

Someone in the Essential stock ROM dump thread just described the exact same behavior that you are experiencing. He hopes reflashing stock will fix it but since it's identical to what's happening with your phone I think he's going to end up disappointed. You might want to check out his post and see if he has any luck. It was the latest post in the thread so it should be easy to find.

Yeah that was me. Trying to get information on the procedure to manually reflash this phone with stock firmware. I shouldn't need to unlock bootloader to do it? Just trying to flash stock over stock to hopefully correct any os corruption. Also mine is apparently a unlocked Sprint variant even though it was advertised as being a normal unlocked variant. Not sure if the firmware from that thread will work for me.

Sorry I didn't notice that. I haven't done any flashing on this phone but I know I read that people with the Sprint phones were flashing the regular stock image to get rid of the Sprint apps and get updates from Essential rather than Sprint. But if you don't want to unlock your bootloader you can download official factory images from the Essential website and sideload using a computer. Flashing instructions are on the download site.
https://www.essential.com/developer/current-builds
Alright I reflashed the latest firmware from essential page via adb sideload. I highly dout it worked but I'll see.
What would I need to do from here to do a complete fresh reflash completely overrighting any trace of the old os? I still want to keep it stock but doesn't matter if I need to unlock the bootloader. Just want a complete wipe of the old os and fresh reflash to be sure any traces of corruption are removed to be sure if it's a hardware issue.
That's easy on single partition phones but much more difficult on phones with an A & B partition like the PH-1. You definitely need to unlock the bootloader. On my Pixel XL you needed to flash the factory image separately to partitions A & B to ensure there was nothing left from before but the procedure might be different on this phone. I went through the flashing instructions when I got this phone and think if you flash the full restore stock image it supposedly returns both partitions to stock automatically but that definitely didn't happen on the Pixel. Considering that this phone is supposed to be easy to hard brick (which was virtually impossible on the Pixel) I wouldn't chance it unless you can't return or exchange the phone from the seller.
Well side loading the ota from essential website didn't work. I'd say it's already hard bricked. Still crashing after a while of using it. Last night I loaded as many apps at one time as I could. Got maybe 10 opened at once before it crashed. Seems like faulty ram to me.
Wife just had it happen on her new White one twice today while playing Pokemon GO.
She says she also had her podcast app and hangouts open but minimized and not being actively used in the background.
She's on a fresh install of Oreo 8.1 with the Gcam mod by MGC_5.1.018_Urikill_vXXII.apk using the settings suggested by aer0zer0
Anyhow I hope its just a completely random fluke and not a serious issue as I have a new black one from Amazon in the mail and would really hate to have to return these otherwise wonderful devices.
Mine ain't no fluke. After it crashes if I immediately reboot it instantly crashes again. I have to let it sit a while turned off and reboot again to any significant time before crashing. Longest time it's ran before crashing since having it it's maybe an hour. Didn't notice it much at first because I didn't use it more than a few minutes at a time. So it was in sleep mode constantly crashing and rebooting. Now that I have been watching it more it just constantly keeps rebooting even while sitting idle. I'll glance over at my phone and low and behold it's rebooting again.

Ouch okay that most certainly sounds like a bad hardware issue as you suspected earlier.
Thankfully in her case the reboots were well apart from one another and the phone was fine after the reboot. Even let her play PKGO.
I mostly came in to comment to hopefully help by voicing that it had happened and the circumstances in which it did for her with the idea it might pinpoint some flaw in the overall system if there was one.
