Help please, Another major glitch after battery blacking out

Dear all,
I have been getting stuck in the splash screen randomly from time to time. Previously, I was and have been having premature battery blackout after a rom upgrade to Dopod 900 newest rom. As I was about to get used to it, I have to learn to put up with another major glitch of random screen blocks.
I have also got thru http://forum.xda-developers.com/viewtopic.php?t=43592&postdays=0&postorder=asc&start=200, but I think the nature of our problem is quite different since my screen get stuck only randomly after some while of usage, bad thing is, everytime it happens, I need a hard-reset.
Any1 with suggestions? Thanks in advance.

[Q] Xperia Arc rebooting randomly for no reason? :(

Hi all,
I recently bought a Xperia Arc, all new, as i started using it noticed it reboots itself often, for no reason apparently, its very annoying since it takes about 2 minutes to restart.
It doesn't matter if i'm taking photos, video, playing games, or even in a call, it can reboot anytime, the screen freezes for like 2 secs then shuts off and restarts.
I cant take it to SE cuz i bought it overseas, and since it's my first android i have no idea what's wrong with it.
It's a wonderful phone and don't wanna have to sell it because of that.
Any ideas on what could be happening? and how to fix it?
Thx in advance.

Install both (required for the drivers):
- PC Companion: http://www.sonyericsson.com/cws/support/softwaredownloads/detailed/pccompanion/xperiaarc?cc=gb&lc=en
- Update Service: http://www.sonyericsson.com/cws/sup.../detailed/updateservice/xperiaarc?cc=gb&lc=en
Use any of them to update/repair the phone back to stock.
Or use the FlashTool and flash it again.

If it continues rebooting after reflashing it, then you need to take it back and get an exchange.

Thanks BluechipJ and daveybaby, im currently at work, so i'll try reflashing it tonight.

I found if the device gets hot (Upper portion of the back, not the battery. I guess that's where the CPU and RAM are), it reboots. It happens more often when I play games while charging. while standing by on battery, mine never reboots by itself. If your problem persists, maybe you need to consider replacing it.

My Xperia Neo used to crash randomly too, usually once a day or once every to days. For some strange reason, it seems to have stopped since I've started using AppKiller and Go Launcher. Right now I'm in the 125th hour of uptime and counting...

yea mine restarts quite often when people call me...im going to take into docomo today and let them know...

been testing it for several days now, the reboots stopped after the flashing
Thanks again

I have flashtool,do I just re run it? will i lose my root/apps/data?

Mine freezes sometimes and then the screem goes of from left to right and reboots
Did you have the same?
Sometimes it runs for 100+ hours and today it happend after 39-46 hours uptime.
It mostly happens when I use it a lot and the RAM was quite low before. Maybe mine runs out of RAM?

Um... could be? Im using a task process killer now so maybe. Try autokilling unnecesary processes.
Cheers

Mhm, everyone says they do more bad than good.
But I'll look at processes that eat up RAM when it runs for a while. Currently it's fast @ ~ 30 hours uptime.

[Q] Blue Screen of Death Everynight on CM11M7

This is the weirdest behavior I have ever noted from my device. I am on the LG E975 with CyanogenMod 11 M7 release. I installed it the day it came out and it was working like a charm, no problem.
However, over the last three days I wake up every morning to find that my phone has a blue screen of death on. I am quite groggy at this point, os I haven't ever tried to read the BSOD (I'll try to tomorrow morning). I shut it down and it goes into the bootloader menu, where it asks me to choose between options like, Power Off, Fastboot, Recover Menu ... And then I can power on like nothing ever went wrong. I suppose its relevant to mention that while hitting the bed my phone is usually near a full charge (>75%) but not plugged in.
This hasn't happened during the day at all.
I do not remember installing any new apps over the last 2/3 days and the only thing that is different is that my phone is on roaming (in the same timezone).
I tried having a look a the logcat but I am no mobile device expert and the one I was able to get in the morning only contained logs from the reboot, so no information about the crash itself.. If anyone has any suggestion on how to locate the problem that would be great.
I really want to avoid a complete wipe. Thanks all.

Leave a logcat here so i can help maybe.
Do you undervolt your cpu frequencys ? maybe you do it too much, or maybe overcock too much.
Also is a good idea check your app wakelock, maybe some wakelock is causing this, some app.

Hey,
Can you tell me how to retrieve my logcat? The one I was able to get is from the reboot in the morning.
I haven't ever played around with any sort of overclocking so that can't be it.
Can you also tell me a little more about app wakelock?
Thanks

With this you can get Logcat.
http://forum.xda-developers.com/showthread.php?t=1726238
Download wakelock detector from playstore and check how many times and what app are causing wakelocks.
Really without logcat of reboot is very hard to say.
Anyway a hard reset should fix this..

LG G3 D855 shutsdown on its own

Hello,
So I bought a G3 the day before yesterday and yesterday was my first day with it, and for that first day my phone had shutdown twice on its own. The first time was when my phone was lying on the bed and doing nothing, it had around 50% battery and was not hot or anything.
The second time was this night i don't know when, i have put my G3 on the charger and went to sleep i woke up and it had shutdown.
I didn't made factory reset when i got i from the box which i will when i come home from work and hopefully this will fix it, but does anyone have a problem like that? If is something serious i will be disappointed to return the phone.
p.s. My previous phone was galaxy s2 and had this king of problem only with custom roms and kernels, but i have not put anything on the G3 yet, except activating the developers options and had switched it to ART and the first time the phone had shutdown i thought that the art was the issue and switched it back to dalvik, the second time though was on dalvik.

I have the exact same problem. The past few days when I go to bed and wake up in the morning, the phone has shut itself off. I haven't rooted or installed any custom roms.

I would advise you both to take a factory reset, only install apps you need for a few days and see if the problem persists, if it doesn't install your apps back one by one as it may well be a particular app causing the reboots.
If you still get reboots after the reset and with no apps installed then you may have to take the phone back to swap it.

Yes as I said in the first post the factory format and hard reset will be the first thing that will be done as soon I am at home. About the apps i have pretty much basic apps (facebook, messenger, soundcloud, etc) all from the market except smashhit of which i have the apk and installed from the internal memory.
Except those apps I have 2 mp3s and some wallpapers and nothing else, becouse when i got my phone it was late on the evening and i had no time to do anything else. So the phone is pretty much out off the box and I was verry frustrated when the secound shutdown happened, becouse i tought the first was from the ART runtime.
Anyway today I will have more time to spend on the phone and we will see what will happend.
p.s. The phone does not reboots, just shuts off.

Is it definitely off or is the phone just stuck on a black screen? It is quite common on some devices when something is not quite right for the kernel to be unable to wake the phone up, the phone is still technically on but stuck in deep sleep.
does holding the power button for 2 seconds turn it on? or do you have to hold it for say 7-8 seconds?

It is definetly shut down around 2 seconds(the normal time to hold the power button to turn on) it turns on and work perfectly and does not show anything suspicious in its behavior, it's super fast, not laggy and etc, may be a little high on ram consumptions but with this havy skin i think it is normal or could not be normal idk, the ram consumptions go from about 1,2GB the lowest i have seen to up to 2,3 the highes i have seen.
Anyway about the shut off think yes defenetly 100% sure it is off, it happend again a while ago and i thoght the same thing may be it si deep asleep even i had chacked the weather 10 min ago and call myself from a friends phone and the operator said that the phone is off or i am somewhere without network covarage.

i got same problem. it turn off it selft and black screen even battery still 70%. rmust remove the battery to restart again, ealy bad. huft

If you have to remove the battery to get it to restart then its not actually shut off, its just stuck in deep sleep! which is usually caused by a bad app.

Yes if you have to remove the battery the problem is different, i just have to push the power button and it boots right away after it have shuted off by its self........

i didnt have this issue with my 855. but i did a factory reset after i got the phone just for the hell of it

So it's reset time i finally have some time to the some staff on the phone so hopefully everything will be fine. I will post if this fix or not the problem to inform the other people in this thread.

did you have any luck with the problem? I have the same issue, performed a factory reset and restored, hopefully it will fix too..

Hi all!
I have and have had the same problem and think I've pinpointed the problem to Google Search but can't 100% confirm it yet. I didn't do a factory reset when I got the phone and it shutdown during the night. I did a factory reset, made sure it got enough time to update everything properly. Problem was gone and worked fine. HOWEVER, the phone kept asking me which home screen I prefer at random times when I hit the home button. With random I mean like 4+ times per day. I searched the net and found a threat saying that a guy with a G2 solved the problem by removing Google Search updates. So I decided to do just that and get the factory version back and the questions disappeared but guess what, the phone shut down the following night.
Any takers or might this just be random? Note that it was working fine for three days with the updated Google Search and shutdown the first night after the downgrade.

So I did hard reset and so far so good the phone had not shutted down itself, and I updated everything which need to be updated (mentioning this for the guy with the upper post). So far so good I will keep you in touch if something goes bad...

Had you enabled ART instead of Dalvik ?

whether the use of ART
The problem will be resolved?

I suggest take it to your dealer and get it replaced asap. I've seen lots of returned phones(my job at XXXXXXX company ) with the same issue, and as long as the defect is reproducible the dealer will give you a new phone. If it's outa replacement period then they'll probably repair it.

aaaaaaaaaaaaaaaaaaaaand shut down again but this time it took quite a bit time longer to shut off by its self so i tought the problem was fixed, but it's not, so i am going to the store which i buy it from to replace the device.....

Does this also happen with the korean models?

Phone keeps rebooting randomly without power connection

I'm sorry if this has been asked before, but I couldn't find a definite answer anywhere. So my Lenovo Z2 plus which is rooted and was flashed with Flyme OS. I was playing pubg and halfway through the game, my phone rebooted. I thought maybe my battery drained but I tried to reboot anyway thinking that atleast it will boot up to show 0% battery, but it didn't. After plugging it in, it would work again for sometime then randomly reboot. And when I would reboot it myself, it stops right after the logo.it only moves further if I plug in the charger. So if it's a battery problem, why does it always reboot at that precise moment. And when it reboots randomly, it's not even hot - the screen, the back, anything. Sometimes it works for hours and would suddenly stop, sometimes it works only for a few minute after unplugging. There's no specific app that triggers this. I even changed the ROM to AEX 5.8, and the problem persists. Is it genuinely a battery problem or is it related to bootloader or anything. Because it does not reboot while in twrp. Any help would be appreciated

Okay, so guys - I am using POCO F1, Started having this same issue yesterday, on the internet, I found - this is a hardware issue, and the solution is to get a new battery,
So I went to the Xiaomi Service center, Their engineer said the same, this is a dead battery issue. So I bought a new battery - and the phone is working fine.
so Final Solution = Get New Battery
Original/local - Whatever fits your budget
