Hard to say.
Could also be a hardware issue.
I recommend to flash back stock ROM with stock kernel.
Maybe you have to wipe data (do factory reset).
Then check again.
Good luck !

You've already done the extreme of reinstalling a stock ROM and performing a factory reset. I'm also assuming you didn't install a bunch of apps before the problem started, though.
My advice would be: go back to stock ROM again, factory reset, and SLOWLY reinstall your apps. This will help narrow down what app could be causing your issue. (if it is an app)
No bumping threads after 54 minutes. Not cool. People here aren't at your beck & call :-/

sorry for that ,but this site is my only hope
i tried ..i put the stock rom without any apps installed.but i had the same problems..by example when i want to delete a widget from the screen the phone stucks a few seconds,and the came to normal..the home button had the same delay and the proximity sensor works with the same delay,when i want to close a call ,stays a 5-10 seconds to light up the screen..i dont know,what is with him,i m disperate
..and what is strange,by example when is on charge ,the home delay dissapeared,works normally,but the rest of the problems remain
comeone..nobody knows anything about my problems with phone?
1.send it to Samsung for warranty.
2.get your money back from "friend".
I think i had similar problems with you previously, even worse maybe. Battery shows charging while cable is unplugged. Some of the time it pops up a warning message "Unstable Voltage". I did the same thing as you, flashing roms, wiping x " i forgot how many times", factory resetting X times and so on. What solved the problem for me was ;
-> i took out the battery
-> left phone untouched for several days
-> put the battery back -> charged till full
-> wipe data, factory reset, wipe battery stats, wipe cache,dalvik as well, FIX permissions
-> flash latest stock rom ( 4.0.4 at that time )
-> reboot phone
-> root again ( flashing stock rom loses root ) using CF-Root
-> reboot to CWM recovery
-> wipe data, factory reset, wipe cache,dalvik as well, FIX permissions
-> flash PA (Paranoidandroid ROM - please follow the instruction from OP post) via CWM
->wipe data, factory reset, wipe cache, FIX permissions
-> reboot phone
-> wait for apps updated and then reboot to recovery and FIX permission for the final time and VOILA!!
The phone works great up till this moment. Not sure if you gonna solve your issue with the way i did it but might worth the try. Nothing to lose anyway it seems as you were hardcore-ing flashing roms and wiping data and such. Good Luck!
Certainly that i hope this will be able to relieve you of the unnecessary distress.

i tried to do all things that you sayed to me,without to leave the phone with no battery several days..dand nothing happend,the problems persist ..i dont know ,i dont have a guarantee,and the cost may be high,thanks anyway

Your friend clearly sold you a dodgy phone. You should demand your money back and use the phone to beat him until he pays. That is my diagnosis and clearly the answer to your "problem".
today after wipe everything and flash de jelly bam rom ,custom kernel etc..doesnt work at all,but i removed the battery for 30 minutes,and when i put it back and openned it ,everything works very well..just a calibrate,and clearly now have no problems..how long it mentain,i dont know,but even now i dont know what it had .. mistery
so,what are you thinking,what is the cause?

So I installed the latest firmware KPQ and wiped data and cache. Everything is working fine with on exception. When I turn on Wi-Fi, only sometimes it stalls and the Wi-Fi icon in the notification bar is stuck at the "turning on" mode.
I do not know what causes this as there is no pattern to when it happens, if just seems to happen randomly. The worst part is when this happens, if I lock my phone, it will not turn on! I have to remove the battery in order for it to work. This is a HUGE annoyance as when I remove the battery my battery percentage usually drops quite a bit.
Like I said, I have the stock firmware (not rooted) and cleared all data and cache prior to and after installing the rom. The issue is random and has only happened three times since the day the rom came out. Which I guess would be about a week.
Anyone have any information on a fix for this? I haven't found anything on this forum or searching google on this subject...
I also have the same problem. I'm on stock XXLPQ (rooted).
First step is backup data and factory reset phone .
Second is reinstall firmware .
How did you install KPQ ??
K is so last year .

Hmm ... should be modem-related.
Try to flash another modem (for your region + mobile carrier).
Then wipe cache and Dalvik cache and fix permissions if you have CWM.
Have you changed the development settings?
Or energy saving?
Or have you a task killer app installed?
Good luck !

Hello, guys. First of all, I'd like to apologize in advance for my bad english. If there is any part of the message that isn't very clear, please inform me so I can correct it.
Here's the deal: I've been using for some time the Jelly Bean Ressuction Remix Rom from Westcrip.
Since about a month and a half (since version 3.9, I believe), I've been getting some weird and random signal drops. Back then, I had to manually reboot my phone so the data connection would come back. At the time I thought it was because the rom was still a nightly build, not very stable, so I coped with it.
This problem has worsen considerably since one or two weeks ago: those "signal drops" have become more and more regular. And following the signal drop, the screen would flicker a little and then the phone would automatically turn off. When I turn the phone back on, the battery is almost depleted, even tho it was full right before the crash. Again I'd blame the RR from Westcrip (by the time I was using the version 3.1.0). When version 3.1.2 came out, I did a clean installation (wipe data/factory reset/format system partition/wipe cache and dalvik, etc), even changed the kernels (used both Dorimanx and Siyah), a lot of modems, and still got this same problem: signal drop (usually when the phone is under a relative amount of stress, like playing Angry Birds, browsing the web, and even while using whatsapp!!!) followed by the phone turning itself off.
I then thought: what the hell, the problem has to be with the rom, not my phone. Then, I tried installing different roms (Paranoid Android and Slim Bean), and still got the same results. If anything, the phone is rebooting even more often now than before. I can't use it for 15 straight minutes and I get that problem,
Since this has happened with all these different roms I dont believe its related specifically to any of those.
Another strange thing: this "signal drop" followed by the rebooting only happens when the phone is disconnected from any power source and being actively used by me. If I'm recharging it, for example, the phone wont reboot at all. Also, if it is over my desk but I'm not using it, the phone also wont reboot. However, if I take it out from the power source and starting using it, I'll get another reboot in about 5-10 minutes of use.
I searched the forum and didnt find anyone with a similar problem... have any of you guys seem this happen before? I'm beggining to think that my phone is gonna die on me anyday now.
Regards!!

Hi, thanks a lot fot the help.
I did all the steps above and I'm still getting the same results...
Another thing to notice is that yhe phone gets really hot for apparently no reason at all (like booting up, running aLogcat and other minor apps), and when that happens, I usually get a signal drop (if the phone is plugged in it wont reboot, if its not, it will reboot).
Is there anything else I can try?
Updating: I've been restoring my old nandroid backups for the whole day to see if the problem had anything to do with Jelly Bean. Well, I've gone back to the old ICS days and every version of it had the same random and constant rebooting. Even versions that didn't have any problem before.
I'm beggining to think I have a hardware failure of some sort. Do any of you guys know what could cause this kind of hardware failure? Since the phone has been getting hot for no apparent reason, it seems to me its a problem with the SGS2 cooler. Is that even possible?
OK so I have this problem but only when using my backup battery. (Not official). When It gets around 30% it begins to make my screen flicker and loose signal and just die.
So maybe you haven't got an original (official) battery in your s2?
Sent from my Galaxy SII
I dont think I have an unofficial battery. Its the same battery that came with the phone (bought from Amazon), and also, mine says Samsung on the back. Dunno if its enough to assume its official. Is there another way to check if my battery is official?

Hi I am also facing the same problem. Mobile is getting hot near the camera lens.
I know there has been a million posts about this issue and I tried all the solutions. Different roms and kernels, factory resets, changing usb, battery calibrations through different methods all with no effect. In frustration I was ready to toss my s2 in the garbage but before I did I decided to try something else (links below) since I figured I had nothing to lose.
It works!! for me anyway. I removed the IC. Didn't replace just removed and my phone now works perfectly. Charges, doesnt overheat. I was reaching battery temps of 80C within a few minutes of turning the phone on before. It was even overheating while turned off! No more warnings or charging paused. So if you have nothing to lose and are ready to toss your S2 like me try this.

When I was on ICS my phone ran without any problems.
I can't really remember but I think I had installed an app and it started making my phone go crazy. So I went to AOKP JB 4.2.2 and started having the high heat problem again.
So I removed an app that I had Vault and set playstore to update over wifi only.
I put the Siyah kernel. I did flash a few other modems and I had the same problem. I flashed current modem and all is fine.
Wipe your cache and dalvik cache too.
Try downloading your modem file again.
All I can say is that my battery can now last 3days (in 2g mode no data) but when I do turn on data it does not suck my battery down in 15 minutes.
*I did click on HSDP option and then turned it back on and off and back on again.
1. I would start with a clean basic ROM. Don't just wipe but format everything 2 times.
2. try different modems (I think this is where the problem is)
3. new kernel or different kernel
This phone is working great now.

Like I said tried everything. This fixed mine. Just sharing for others who have also tried everything. I did check the capacitor in question was the source of my problem first and there was extreme heat coming from it.
Im Argentinean first of all and I'd bought my new GS2 3 days ago on mercadolibre.com.ar (a site like ebay.com) to a guy that imports it from factory. After of almost 50 days of waiting, i did got my new mobile phone, when i got it i'd upgraded to JellyBean with the official samsung rom, and that's when the problems showed up, the top left corner come overheat turning off the device, over and over again. So after some failed testing I'd chosed to change the kernel to Siyah expecting some performance improve but it become kind of worst because when the screen blackout the device just reboot itself, but if i keep doing something on it nothing happens, just when the screen comes black.
So i guessed that it may was related to the kernel, so downloaded another official rom jelly bean, this one was a Pre-Release rom, that some time ago i'd installed on a friend's galaxy s2 and it worked fine (despite the increased battery drain). This wasn't any solution though, because it keeps rebooting when the screen comes black.
I did tested to turning on without the simcard and microsd card, with the same results.
Another fact is that if i left the music playing and turn of the screen with the power button, nothing happens, it works perfectly.
It seems that is some kind of trigger when the mobile actually suspend itself doing really nothing.
Now i dont know what to do, should i test some custome rom/kernel?? should i get the chances to use the warranty? (implies to send again the device to china i guess ¬¬)
Please help, and thanks in advance.

You should try custom rom. Try to Flash Neatrom or any stock custom rom.
Hope it solves your problem.

Because your phone is now in Bootloop.
Bootloops can occur pretty easily, it’s mainly caused because system files interfering with each other which causes instability and/or crashes at the boot sequence.
Think of system apps that are compiled incorrectly, permissions that are not set correctly, files from other devices and even an init.d script, everything is possible.
To find the cause of a bootloop you have to think about what you did before getting the bootloop.
Choose one of the following reasons that caused the bootloop for you and try out its solution.
– After flashing a new rom
If you flash a new (base)rom on your device it may not automatically wipe your dalvik-cache, This means your old dalvik-cache will be used for the new system files which would result in a bootloop, to fix this problem:
1. Start your phone in CWM Recovery
2. Go to Advanced
3. Choose “Wipe dalvik-cache”
4. Now go to “Mounts & Storage”
5. Choose “Wipe /cache”
6. Reboot your phone
Note: by wiping “/cache” and “dalvik-cache” you make sure it’s completely deleted, some roms use /data and some use /cache for the dalvik-cache
If the problems still exists after doing that, you could try to wipe your /data partition. before you do that first make a backup of your phone (in it’s current bootlooping state)
1. Start your phone in CWM Recovery
2. Now go to “Backup & Restore”
3. Choose “backup” (it may also be called “backup to internal/external sdcard)
When that’s done you are free to wipe /data, you can achieve this by doing:
1. Now go to “Mounts & Storage”
2. Choose “Wipe /data”
3. Choose “Wipe /cache”
4. Reboot your phone
If the rom still doesn’t boot correctly it’s probably the rom which isn’t working, contact the rom creator then and try an other rom for the meanwhile.

Think of system apps that are compiled incorrectly, permissions that are not set correctly, files from other devices and even an init.d script, everything is possible.
To find the cause of a bootloop you have to think about what you did before getting the bootloop.
Choose one of the following reasons that caused the bootloop for you and try out its solution.
– After flashing a new rom
If you flash a new (base)rom on your device it may not automatically wipe your dalvik-cache, This means your old dalvik-cache will be used for the new system files which would result in a bootloop, to fix this problem:
1. Start your phone in CWM Recovery
2. Go to Advanced
3. Choose “Wipe dalvik-cache”
4. Now go to “Mounts & Storage”
5. Choose “Wipe /cache”
6. Reboot your phone
Note: by wiping “/cache” and “dalvik-cache” you make sure it’s completely deleted, some roms use /data and some use /cache for the dalvik-cache
If the problems still exists after doing that, you could try to wipe your /data partition. before you do that first make a backup of your phone (in it’s current bootlooping state)
1. Start your phone in CWM Recovery
2. Now go to “Backup & Restore”
3. Choose “backup” (it may also be called “backup to internal/external sdcard)
When that’s done you are free to wipe /data, you can achieve this by doing:
1. Now go to “Mounts & Storage”
2. Choose “Wipe /data”
3. Choose “Wipe /cache”
4. Reboot your phone
If the rom still doesn’t boot correctly it’s probably the rom which isn’t working, contact the rom creator then and try an other rom for the meanwhile.

No is not, the cellphone starts normal, and while im using it nothing wear happens, but when i left it the screen goes black and the device reboot itselfs. But now im seeing that doesnt happen anymore, i dont know why.
Still with cyanogenmod rom, i connected the phone to charge the battery, and i saw a tendency of reboots and turnings off while the percentaje comes to 100% and a increasing overheat on the left-top of the phone, i suspect that the problem may be related with the amount of charge from battery and the overheating... Hardware problem?
Well... After all this time my cellphone went through the argentinean official service of samsung and the tech guy told me that he couldn't do anything on my device because he tried installing a lot of samsung official roms and the device was still malfunctioning. So he gave up on it, so i'd tooked it to another service (non official this time) and that guy told me that it may be a non official device, so he wouldnt do nothing on it, because i couldnt get the hardware that possible was malfunctioning. So here im now, with the all money spent for nothing.
My question is, what can i do to know if is or isnt an ORIGINAL samsung device? Knowing that i'll choose how to proceed. Txs!
