[Q] Random Reboot Troubleshooting? - EVO 4G Q&A, Help & Troubleshooting

I'm running CM 6.1 RC1 currently, but I have had random reboots ever since I started using CM 6.0 nightly. (stock kernel)
I havent been able to get any responses in the CM threads since there are so many people posting in there.
At first my reboots were only happening when I had my phone docked in the car and navigation/other video was playing. Now I seem to be getting more reboots with just web browsing or playing games.
I tried to wipe my phone and put only a few apps back on it, but that still doesnt seem to help.
Is there anyway I can figure out what is causing the reboots? Will a logcat show the problem?
Thanks

I've been having a similar issue after attempting to upgrade from fresh 3.2 to 3.3/3.4, especially when trying to connect to a wifi hotspot for the first time. This also happened to me a few months back with the cause of the issue being the gps. I was able to solve that issue by reverting back to unrooted stock and performing a master reset. I'm going to try this method again and see if it helps. I'll post whether it fixed it or not. Can you narrow down the cause of your reboots at all?

I thought originally it was app related. I flashed a new rom, and had almost no apps on there. Still had the same results. Only thing I can try is a complete wipe, and install no apps. I would need a few days where I dont need my phone to do that. That's why I was hoping there was a way to debug from logs.

I've been dealing with the same issue for about a week now. My phone started rebooting just a few times a day, but the last few days it reboots every few minutes during use (not sure if it reboots while not in use). I wiped a thousand times, flashed and reflashed a half a dozen different ROM, went from Amon to Clock and back to Amon, but nothing works. I reformatted my SD card a dozen times as well. I called Sprint last night, and they're sending me a new phone in the mail. But I want to understand/fix the problem for hubris sake.

I just ran the latest RUU and rerooted and it's still randomly rebooting.

My phone would reboot every minute on any rom but rooted stock called sprint got a replacement. Rerooted

We have gone over hhis a thousand times, and it seems (as Eric cartman would say) we are fed in the a. It is a hardware related problem that mostly occurs on rooted phones. Unrooting does bubcus. Go to sprint store, spend from cristmas to new years in line, show them the problem, and get a replacement. There have been no other solutions found.

Exactly what I would have done. Here's hoping I won't have to.

can anyone post a logcat or DDMS log?

That happened to me. Other than the android process media thing. If you go into terminal emulator and type
Su
Fix_permissions
. And let it run through it fixed any rebooting problems I had. I found it happens when running new apps. So I just run it after every app I install.

Where is the DDMS log stored?
Will the logs retain the information say 10 minutes after the reboot? I usually get the reboots in my car.

The random reboots that happened to me were from using siedio 1750, when I switched back to the stock battery and now the HTC 2600mAh battery, the problem has since now been solved.

Unexplained Random Reboots On Froyo

I honestly cannot find the cause of this. I Have tried everything in my power to try to fix this problem but absolutely nothing seems to work. When using my phone regularly (only on froyo) my phone will get very very hot and then start a reboot loop where it keeps rebooting and rebooting and rebooting. I have the official 2.2 update. Currently not rooted but S-OFF. I wanted to see if the root was causing any problems but im still getting the reboots. I Love my Inc. and i love the AMOLED screen. I want to be able to fix this problem so i dont get stuck with a ****ty replacement. PLEEZ HELP MEEZ
first thing would be to tell everyone what ROM you're on and if you're running setCPU.

I get this problem all of the time and I will tell you it has nothing to do with root. In fact, I'm not sure it is even a software issue. I have done multiple factory resets to try to troubleshoot the problem.
There is a thread at AndroidForums about it that I am currently running, but I can't link to it evidently. Look in the Support section for the Incredible.
How did you update? You're running a 2.xx radio, right?
If your problems are surviving a full wipe + RUU, the most likely culprit is that your hardware is failing.
It's a full wipe stock 2.2 and yes I have the newest radio
I was having the same issue with my phone on Stock 2.1, Stock 2.2, custom ROMs, etc. No software updates/configurations would make the random reboots stop. Anything that taxed the CPU seemed to cause my reboots. The easiest way to reproduce was to just start GPS'ing somewhere. Within minutes, the phone would go into a reboot loop that would usually only stop after a battery pull.
I took the phone into VZW while it was doing a reboot loop, showed it to them, and they put in a replacement order for me. The replacement (yes, it's a refurb) has been rock solid over a few days of heavy use. I read that if you had an AMOLED screen, then you're replacement will also be AMOLED.
tl;dr; - random reboots on stock ROM with no mods is probably a hardware failure. Go with a refurb.
Decided to go to VZW and order a replacement. They told me it would be a new phone and not a refurb but I don't trust them. Anyways it comes Thursday. I shall report back my friends. I still find this problem to be so odd

Random reboots

I had the Photon so random reboots aren't to surprising to me. Hell even on my old T-Mobile htcs I flashed so much random reboots were the name of the game. But with my phone rebooting at least 6 times in the past 24 hours, I'm not too thrilled. It happens doing the most random tasks. Stumble upon, trying to open Gmail once, internet browsing. I'm wondering if this is because of root or just the phone. Anyone else experience this?

No random reboots here. Did you flash any kernels or are you stock?
I got my phone Friday 9-16, still 100% stock no root and I have not had one random reboot. If you are on stock without root you should return your phone, sounds like it is defective to me. When I saw random reboots in the title I thought I was in the Old Epic section
random reboot = probably a dud
manufacturers manufacture thousands of these devices a day, and flaws unfortunately occur

I am rooted. I first rooted with the Zedomax method, and then tried v5 of the ACS method two days ago, which is when I started getting the random reboots. I now switched to the Zedomax Overclocked Kernel (not using the overclock) to see if that fixes anything. If not maybe they'll release the stock kernel soon, and find a way to reset both flash counters.
Im completely stock and have had 2 reboots today. At first I thought maybe my hip case was pressing buttons but I had it out on my desk and then I hear it reboot. Im like WTF? I remember it did this on day one a couple of times and maybe a couple since then now I get 2 today damn near back to back. When the update comes out to fix known issues, hopefully this is one of them!
just got one today. Running Stock..
I am completely stock. No root. I've had 3 already.
I've reverted to the stock kernel with root and no reboots so far. I'm making sure to keep my number of open apps low though

I've had 2 random reboots tonight. One was while uploading photos to facebook, the other was while it was just sitting in my cupholder in the car. The cupholder one was weird though, the screen was on, and it made the reboot noise. It was like it lagged on it, but the phone was still semi usable for about a minute, then it finally shut off and came back. Another thing is random keyboard freezes, and again tonight, my settings menu wouldn't come up until after I restarted it.
So far in the week of having this phone it has rebooted twice

Well, it's been 4 days now without a reboot. I'm guessing stopping services makes this thing go crazy. I thought stopping maps, turning off background data, etc would make battery life better (like it did on the Epic)...well, it doesn't, and like I said earlier, freaks this thing out. So, don't stop anything, and it'll be fine.

I haven't had a reboot in a while now. Since reverting to stock at least. Although randomly my phone will freeze up and ill have to lock then unlock the screen

Mine is going to be 1 week old tomorrow, and I am currently stock (so weird for me I root as soon as I get a device), but I honestly havent felt the need to root, and I also wanted to run a stock device for a while.
Anyhow, no problems here phone is running solid, no reboots or anything.
I had to do manually restart yesterday in order to get the camera working again. Went into the camera, and it was just a black screen with the controls around it. I love Android, but I hate that it isn't as stable as BBOS, or even iOS.

How do I diagnose random reboots for my Note 2?

For the past 4 days my Note 2 has randomly rebooted at least once a day. I wasn't using the device for most of the reboots and just noticed that it rebooted because of battery drops. I don't really know what could be the cause since I don't remember changing anything recently. Is there any way I can diagnose this without root?
How about just flash stock rom? If you dont have lots of apps which you've used, then it should take care of problem without needing titanium backup which needs root. Just save ur data using kies and flash stock rom from sammy.

I'm actually currently on stock and unrooted. I was just wondering if there were ways to find out what caused the reboot such as logs and such? Or if there was an app I could install to keep track of what causes a forced reboot?

You could download alogcat from the marketplace, its free and will save a log of what's going on with your phone.
It might help find out why its happening
for me it happens cause the power button is so easy to press while phone is in pocket.
keep it pressed for some seconds by accident and phone reboots. even if screen is locked.

If your rooted run a logcat and that will tell you what happened right before the reboot, reboots are usually a Kernel Panic meaning something caused a big enough problem that it couldn't be recovered and crashed the core of Androids software "The Kernel".
As others have noted flashing a stock rom ideally via ODIN and then testing your phone may let you know if you had bad software or a hardware issue. Custom roms can have bugs that will cause kernel panic a stock rom should be 100% fine and reboot free
I find mine will sometimes reboot after copying something to the clipboard.

I had reboots on my previous unrooted HTC EVO. The problem was an app. I was able to diagnose the problem by looking at my install/update log. Basically, I uninstalled all apps back to the date I knew it was stable and waited to verify it was stable. Then added back one app only and waited. Repeat. About a week later, I added an app that caused a reboot within hours. I uninstalled it and the phone remained stable.
Here's where I found a chronological listing. If you have multiple devices, it will show all apps for all devices (tablets, vizio, phones,etc)
Google Play> My Android Apps> at the bottom My Orders & Settings.
This gives you a cronilogical listing of app installs and updates.
Mine turned out to be a call recorder app that I had put on the phone 4 weeks previous.
Seems like a Samsung issue:

I've got the same problem worth my note 2. At least I know I'm not alone.

Bad SD cards are also a notorious source for spontaneous reboots. If you have one inserted, it should be easy enough to retract it for a while to test it. ..
Note'd too from my N7100...
I'm also experiencing this issue. I'm using 4.1.1 Brazilian stock ROM here.
Even before flashing CWM (yesterday) I as going through this problem. Most times it happens when the screen is off.
Maybe changing the stock Kernel to a custom one would solve this?

[Q] How to troubleshoot random reboots

Hi all,
I was using Rootbox for a couple of months, now since 2 weeks I use P.A.C-MAN. With both ROMs my phone reboots randomly. Sometimes it might be a couple of days without any problem, sometimes it's 2-3 times per day. I have never experienced this problem with the stock 4.0.4 ROM.
Probably I have installed an application that causes this or there is a setting which is not optimal, but I have no idea how to troubleshoot this. I tried looking in the logcat, but it's too large and verbose and without any concrete idea what to look for this seems hopeless.
I'll be thankful for any ideas that could help me solve this problem.
Bump?
I had the same problem with my phone, figured out it was the battery. When the reboot happens does your battery level goes down?

No, the battery is fine. It happens with with fully charged battery too.
Do U resolve your reboot issue??
I have same...
My phone reboot even i recovery mode
All issues began after flash with PAC 1.2 or 1.3 togehder with rotation issues,
now on CM 10.1..726.. and they don't away...
My suggestions is to check logcat. Try to find the moment when the phone rebooted and see if there is any relevant error message right before it. If you can't figure it out by yourself, I suggest you post the logcat file here. Others my be able to help you understanding what is going on.
This is realy strange....
After two/three days with reboots (ca. ten per day), it away like a magic.... now I have 3 days uptime
I turn off pin walidation, for login to network after reboot in my pocket, and add uptime on desktop to see when reboot was...

I'm having reboots while using Chrome. For example, if you go to the Play store and attempt to manipulate that navigation box in the upper right corner Chrome either crashes or causes the Nexus 7 to reboot.

ASUS you suck. Google please use Samsung for your devices k thx..
I still have random reboots on my unmodified Nexus 7 2013. I've been running KitKat since it was OTA'd to the device a few weeks ago.
It is excellent when I'm in the middle of something and the screen freezes for about 4 seconds, then the device reboots.
EDIT: Hilarious. It randomly rebooted on its own just now. The device had been sitting unused for a number of minutes. Usually doesn't happen more than once/day. It just happened twice in 45 minutes. Usually it happens about once a week...
Anyone have any update/luck with solving it? I'm making a nandroid backup just in case the worst case is I need to have it sent back to the store for a replacement..
I posted this in another thread, with someone asking if a custom kernel will fix the reboot problem plaguing this otherwise superb device. It seems to hold its relevance here.

So, here's my experience with this. I bought my first nexus 7.2, at a best buy in north Dallas, in October. I experienced random reboots, right out of the box, about once a day, usually when I was browsing chrome, or when the tablet was sitting on the home screen without being touched. My gf bought a nexus 7.2 as well, at the same store in November, and she was not experiencing any random reboots, hers has always been stock, to this day (my suspicions began). I figured it was a software, or app problem, and waited for a fix from Google, or my app developers. Tried various custom Roms in the meantime (cm11, dirty unicorns, silmrom, and many more). I also tried various kernel's, in combination with said Roms (Franco, ElementalX, glitch, bulletproof). I had random reboots with all combinations of Roms and kernels. Did a factory data reset after every update from Google, and tried it for a week or so every time. Still experienced random reboots. I finally got fed up and took my table back in early January, to the same best buy in north Dallas. After receiving my second tablet, I kept it stock for a week, and then restored my preferred twrp backup, that I had taken with the rebooting tablet ( stock 4.4 krt16s, xposed framework, ElementalX 2.2 @1.7 and 450, with the motoX dalvik and bionic patches). With the new tablet, I have not experienced one random reboot, either with the stock software, or the custom software.
So, long story short, if your experiencing random reboots, if you have the ability to, I would take it back. Maybe you can fix it with software enhancements, but IMO it just shouldn't do this, stock or otherwise, and warrants a return.
Whatever you choose to do, I hope it works out for you, the reboots were personally driving me crazy, and I'm glad my second tablet doesn't reboot like its got a mind of its own.

With my personal experience, it definitely seems to be a hardware problem.
Thanks for reminding us. Seems to be a hardware problem. Mine still random reboots intermittently. Usually when it does, it will happen maybe 2-3x/day, then go a few days without happening at all. As is the case with me, it happens most often while sitting at the home screen, not in use. I've always been stock.

Same thing with me ... hate this problem, it make it unreliable especially for work and collecting data ...
Mine has been doing it lately also. I noticed it happen the first time about 2 weeks ago. It has done it on 2 different ROMS.
mine does it as well - as well as two other friends of mine who have the same exact models, all purchased at different times. it must be a device issue. there is no point in returning your device if its randomly restarting because youll just get another one that does the same exact thing.
however the longest uptime ive gotten so far was 200 hours with franco kernel r12 and then opened chrome and got a reboot.
also the same thing happened on my nexus 5 in the same day, maybe it was just an incident with google chrome. both devices rebooted.
but im having better luck without random reboots using a custom kernel (franco r12).
I turn off my device every night, so I do not have any random reboot issues. I think a simple restart every 2-3 days will fix this issue
You should always reboot a wireless device MINIMUM once a week to clear out useless data and avoid problems.
