Hi,

I recently bought a Nexus 5 in Antwerp, Belgium (about three weeks ago). The build number is KOT49H. The first few days I didn't receive a reboot but after downloading a couple of apps, my phone rebooted about 4 to 5 times a day. I decided to RMA the phone and since an employee from the store I bought it from said I didn't need to store it back to original settings I just deleted my personal information and some apps. Then the reboots just weren't as active as before, I received one or two that week and decided to just let it slide for another week or so. Now I rooted my phone for viper4android and to check the last_kmgs files and noticed the reboots are because of kernel panic.

It also seems the reboots are almost always in the weekend when I am at my mother's house (in the week I live in a student room).
So if anyone has some advice or needs more information, just ask.

Thanks a lot.

Well..... If you had a phone and these problems happened because of "apps and viper4android" and then you got another phone and did the same thing and get the same result then it is obviously something you are doing. Did it do this before you loaded your apps and viper4android? What method did you use to root/ how did you do it? I highly doubt the time of the week has anything to do when it reboots but I could be wrong.

A kernel panic is defined as "A kernel panic is an action taken by an operating system upon detecting an internal fatal error from which it cannot safely recover."

You are obviously doing something that it does not like.

I searched some of the lines of code and compared it to this thread here: http://xdaforums.com/showthread.php?t=2553949

Try loading a different kernel. It doesn't matter anyone and see if that fixes the problem, you are rooted so it should take three minutes.

Well it started before I rooted the phone. The apps I do use are nothing too special just the regular games and chat services that almost any normal smartphone user has installed. The method I used to root was in a thread I found on this forum and on the first page of google. Well, my phone hasn't rebooted once when I was at my student room and has rebooted about 4 times this day when I am at my mom's. And I didn't receive another phone yet. This is still the phone I bought originally from Mediamarkt in Antwerp.

I edited my previous post and may have a solution, try and load a different kernel since you are rooted.

Also the reboots happen when the phone is idle. It happened like two or three times the phone froze while using Google All Access and just rebooted. I am pretty sure the reboots aren't because of my faulty usage.

I will try the different kernel but I still feel not pretty comfortable that the original kernel just reboots. Maybe RMA is my only solution? Thing is the employee from Mediamarkt said I'd miss my phone for minimum three weeks. I don't even own my phone that long.

kernel panic is because of a different error. it can be caused by just about anything. in the partial last_kmsg that you posted, you didnt include the error, only the outcome of the error. chances are that its an app causing it though. yes, apps cause random reboots. there are too many that arent written very well. i suggest wiping your device and not adding any apps for a day. if you dont get any random reboots, add one app at a time until your phone starts rebooting. then youll know which app it is and isnt.

This is the last zip file syslog provided me. Hope it has more information.

looks ike an i/o error. it had trouble transferring data to a sector. i dont know what would have caused it. an app issue, a corrupted sector, whatever it was the phone doesnt like it.

id try running the phone without any installed apps for a day, see if it still reboots. if it doesnt, it was an app. if it still reboots, id wipe out the phone completely and flash the factory image. its also possible that a sector is corrupted somehow, or the data in it. a flash of the factory image should take care of it.

Thanks, the thing is though that it rebooted three times while laying on my nightstand this day, every time I checked to see what time it was it was on the sim lock screen. Now during the day with average use (only using whatsapp and all access) it hasn't rebooted a single time. If there was a way to ensure a reboot I seriously don't know how to. If a flash of the factory image would be the final step, it may be in my best interest to start with that immediately instead of trying one day without apps? As I sometimes don't register a single reboot in four days.

i think a day without apps first would be best, at least it would tell us if it is an app or not. one time on my gnex, i started getting random reboots when there were none before. about 3 days worth of reboots had me confused. i was about to flash the factory img, but i remembered i installed an app the day before the reboots started. even though i only opened it one time since i installed it, i decided to try removing it first. so i removed it, and never had a random reboot on my gnex since.

Oh ok, I'll try this as soon as I'm done with my finals monday since I still use whatsapp quite a lot to discuss studying material. I also only got like 5 apps. The only apps that aren't recognized worldwide might be "De Lijn" app, which I use to check the bus times and "MyMobistar" to check information about my provider. Could this also be because something is faulty in my phone itself and that the only resolution would be to RMA it?

its possible. if it still happens after flashing the factory img, and some time without any apps installed, then id say the phones hardware is faulty, and rma it.
