Phone Flickers Then Shuts Off? - Galaxy S II Q&A, Help & Troubleshooting

So I had this problem constantly. My phone would flicker from nowhere and then it would shut off. Any ideas what the problem is? This happened on stock unrooted 4.1.2 as well. And now it is happening on Revolution ROM '14 edition. Any help is appreciated.

I'm having this with every rom/kernel I use. It either overheats when overclocked, and when it's not because of the temp., it happens when I play big, 3D games like GTA 3, etc.

Check cpu temperature

Vibrant randomly reboots...HELP!!!!

Can someone please help me. My Vibrant just randomly restarts or freezes mostly w/calls. I didn't have these issues until I received T-Mobile's OTA the other day. I came here and seen others complaining about the exact same thing. I then began to read the instructions, on how to get into Download mode and flash J16 through ODIN. I thought I was all good until my phone would start to reboot w/incoming and outgoing calls and randomly freeze on me. I thought it was an issue with that specific ROM so I flashed JC OC/UV ROM and yet the problem persist. Does anybody have an idea as to what the problem is? Oh, by the way I am ROOTED.

Had similar issues, used rom manager to boot into recovery menu, fixed permissions from there, then cleared dalvik cache and that fixed my problem.
Sorry! Didn't work.

Do you have any gameloft games or adobe reader?
My phone freezes like that whenever I've used a different kernel with Voodoo. But it sounds like you have the problem with or without a different kernel.

Yes I have Asphalt, and Avatar. I also have Adobe Readerâ„¢. Is that what's causing it? If so; what about those apps and games cause my phone to randomly reboot and freeze?

I'm also overclocking. However this was happening before I started overclocking as well.

Make sure your min setting in setcpu is 200 and set the Max to 1 ghz. Apparently some phones cannot handle OC'ing, mine being one of them. I personally prefer the stock kernel because I have only had problems with other kernels with or without Voodoo.
As for adobe reader, if you search you will find several posts regarding an issue whereby the app causes our phones to randomly reboot. Same with some gameloft games. I for a fact know hero of Sparta is no good in this regard.
Good luck

[Q] Slight delay when powering on?

Is anyone else getting a slight delay when pressing the power button when the device is off? It's not hugely noticeable but slightly annoying!
I'm having the same issue
Sent from my GT-I9100 using XDA App
I have had this problem to, but when the phone us charging there is no delay.
Sent from my GT-I9100 using XDA App
Probably because it's trying to conserve energy and goes into a lower power state than when it's plugged in
Doesn't bother me at all

This has been rectified in the latest firmware update.
I have the last update. And the problem started on ke2

XDA App eating battery when running in background?

I've noticed that my XDA app on the Galaxy S3 (ATT) is eating up alot of battery. Ate almost 40 minutes of CPU. One time when I went into task mananger, it showed high CPU usage and I wasn't even using it for a while (so it was idle). I also noticed this with the Engadget app.
Anyone notice anything similar? Just seems like they should be sleeping and not using CPU in the background...
Try reinstalling them. I haven't had this problem with either :/
See attached. My screen has been on about an hour and xda for 50 min.

All I can think of is to reinstall. It shouldn't be doing this obviously
I've uninstalled and reinstalled before those screenshots.

Well no idea then, sorry. You could force stop them when you aren't using them.

i'm having the same issue. att sgs3 completely stock never flashed rooted or odined. my phone also seems to stutter and lag a bit more than i was lead to believe it would but i really only started to notice it after installing xda.
i have been using the xda app quite a bit today but an app doubling the screen in battery drain just seems wrong.
xda app cpu times:
total: 2h30m
foreground: 55m
i'm thinking about flashing the stock firmware odin package....... but i'm also thinking about trading in my blue for a white and i think the obvious lag stutter problem might help me avoid restocking fees.
oh what to do?
so no one else is having this problem? just us two?
I'm having this problem as well. I had 90% when I went to bed. 6 hours or so later when I woke up I had 50% left :/

I have also been having this problem since my s2. You can see in the task manager its running about 10 pct in the background. Never found a way to stop this apart from manually closing the app in its settings or force close.
I have been having the exact same issue with my XDA app. It just sucks the battery, using 20-35% on average. This is very odd as I have never had a problem with the xda app before. This is an app issue, hopefully they will update this.

I also have this problem. I've been manually fcing the app. I assumed it was due to the app trying to serve adds. But I don't really know

Guys, I've had a little better luck...at least its not killing the CPU total (was above 20% before on idle). I've disabled notifications in the settings and I've also disabled the 2 listeners using AutoRun manager.
Does anyone here who is experiencing xda app battery drain have a rooted device with an ad blocker? I have never had this issue with the xda app and the only thing that has changed other than the phone is not being rooted /ad free. My guess is ads are somehow causing this problem.

[Q] When playing emulators on phone (gameboid, etc.) Or surfing internet phone will s

As the above reads, my phone will shut itself down if I'm playing games or am on the internet. Usually its when I'm on tumblr and have gone waaaay down the pages. I'm running PACman 19.3.0, jellybean 4.1. I'd love to know if there's anything I can do, just short of reflashing to my old CM 9... Thanks in advance to anyone who can help!

There could be a lot of things making this happen. It seems to happen more under heavy load as you stated, maybe try another kernel? Are you underclocking/undervolting?
Sent from my GT-i9100 using xda app-developers app
I was thinking it might have something to do with my clock speed. I'm not sure what is a safe speed to move it up to. I'm running at 1100 MHz right now. I think the Max on the scale is 2000. I was also thinking it could be battery related, as the issue does not occur when the phone is charging.

try the stock browser or some other browser from store's and see if u have the same issue for now
Ans also when ur on 'Mobile Data connection' , Heating is quite common due to signal variation's.
