You should first install "Android System Info" app frm playstore....
Then in Tasks tab , check out the CPU usage..and then post again...
Check out the CPU usage when the phone is normal and when its hot...

I will try that thx, but i not sure if it can because when the phone is hot its completely dead as screen is black and pressing any buttons will not do anything. I will need to take out the battery and reinsert every time.
It happened to me just that even after battery insert it wont boot. Fixed after warranty claim which replaced screen and mother board
I am in a difficult situation as i brought my phone sim free in the UK but cracked the screen while i was in Malaysia and got Samsung Malaysia to replace the screen. they only had back colour screen so it is a black screen on a white S2. It has some void warranty stickers on the phone after the repair but i not sure if my warranty is still valid in the UK. i am not sure what to do at this stage.
Hi,
I have same problem. My S2 suddenly shut off due to low battery. After that not starting, not charging. Samsung Service Centre says change motherboard. My phone is S2 official ICS.

Hi
the Samsung galaxy S2 is my second android phone(the first being HTC wildfire).I like the phone.This morning when i was browsing, the phone started getting warm,it happened to me before so i ignored it,then the entire screen,instead of displaying white i got light green colour all over it,so i panicked and did a factory reset and now everything seems fine,What might be the problem,Do i have to return it?
BTW i am stock rom updated to the latest firmware
Thanks
Alright, it have never happened to me. It might not be anything at all - Just a tiny bug - or it could be something serious.
If there is a problem with the OS, the factory reset could have helped. If it keeps doing it, it can be fixed with eg. flashing another fw.
If its a problem with the screen, you might wan to have it replaced or sent it in for repair.
See if it happens again, and then we'll take it from there, k?
I would at least try to close and open the browser again before doing a factory reset
This might help a little. (Click me)
I've had this once too. The colors changed to somewhat inverted colors. It has to do with the auto-adjusting the phone does depending on what is on the screen. It happened when I still had the original Samsung rom running on it.
If you have this again, update your phone, or flash something not stock!
Check your battery graph
Did you experience a sudden extreme peak in the graph at the point when this happened?

If it does it again take it back, but the problem is that it might only do it once every six months or something like that. If that's the case can you live with that? Hard decision but I think I would wait to see if it happens again, try installing 2.3.4 stock

I would try to run the phone a little hot to see if that was the cause. If it happens again I would return the phone.

Stress test it, burn baby burn and see if your phone gets upset at being hot and turns into the Hulk

dropped to 10% from 60%?
I had an issue whereby the screen turned bright red/pink when I was using the stock browser. But my battery graph showed a momentary sharp peak up, instead of a reduction.
Is your drop momentary or it just stayed at 10% from then on?
Just for the record....
I've just had a very brief momentary bright green flash. First time this has happened since I bought it 2 months ago.. Playing Spider Solitaire.
Battery graph might shows a teensy 1/2% spike.
does this happen to you?
i was playing on my tablet then the screen turn soooo dark
like as if the bright setting is turn all the way down.
i can hardly see to operate, i press the power button then again to login.
but when i check the setting it appear untouch
even after turning off auto brightness.
Mine kinda does this... mine just goes super dark, but i usually just touch the screen or the power button and it brightens back up, just like a laptop getting ready to go into sleep or hibernate mode.
It happens again after I set timeout tok 30 m3inutes
It could be bad lcd, I could not see a thing.
That would suck if it is a bad LCD, but at least it would be under warranty!
This happened to me, I think it is because I had brightness at maximum... I turned the brightness slightly down and it has happened again. But maybe that's just me?

It has a light sensor and auto-adjust capability. I've notice as I move around with mine or change how room light hits it will darken or brighten. Doesn't bother me enough to go looking for some settings to disable it, but there should be some there.
I have the same problem too... everytime I turn off the screen using the power button then turn on again the screen turn very dark when the setting is set to auto brightness... it is very annoying while doing something on the S and went away from a while then come back to use it the brightness is totally so dim...
I'm sorry to say but you guys have a defective unit. Just switch it in right away.
turn off auto brightness.
I contact newegg yesterday but no reply yet.
edit: i call them via phone got my shipping label.
Turning off auto brightness doesnt help, but tuning down the brightness from max down slightly I havent had the issue.
If it happens again ill have to send this back, I feel bad loosing the official siony screen cover.
Byt loosing $30 is better than five ninty-nine us dollars.

my xperia x10 2.3.3 fw and before that doesn't bug me this much.
if all 3.2 fw tablet does it then i would blames on 3x
go ahead turn on your auto brightness and browse the net in a well lid room.
I have one that is doing the same thing. Also every now and then the screen shuts off and I cant get it to come back on for awhile unless I hold power for like 30 sec. Is this a defective tablet or honeycomb 3.2? Thanks!
I'm telling you guys, I sell the things andI KNOW the issue they are taking about. We played with the settings all day and it kept happening but the issue NEVER happened to any of the other units. It's most likely a defective unit because as I said, it only happened to the one unit.

Hey guys,
This is my 1st Samsung & Android device. Bought it 4 days ago. But I have a strange screen issue . Whenever I press power button to unlock screen or turn on phone, some white vertical bars appear for miliseconds and lockscreen shows up. I'm using checkrom but same problem appears on every rom i tried like darky rom, cyanogen or stock this annoys me so much! I got it from when I was in a foreign country, samsung's international warranty is not applicable in my country. Am I in trouble
i have same problem.
its really very crappy on microbes live wallpaper(not so smooth),
also sometimes its camera get failed and i have to switch off the phone to get camera again working , same happens sometimes in video player,previewing image after taking image from camera takes more time.
someone plzzzz help me to fix this.......
I sometimes get that but a reboot usually fixes it. I think it may have to do with low battery voltage because it only happens on 1 of the 4 batteries I have, usually below 50%.

Hi, first sorry for my english, I hope that it will be clear enough to understand my problem...
My Xperia Ray, updated to ICS, display a black screen (with backlight) when waking up after a stand by. I have to wait for undertermined time to have something on the screen, sometimes I remove the battery and boot the phone to be able to use it.
I updated it to last 4.0.4 ICS thinking it will resolve the issue, but it has not.
I can still use the phone when connected to MyPhone Explorer with the phone keypad, while the mobile's screen is black the MPE windows shows me the "normal" mobile screen. Everythings else works normally.
I'm afraid to give it to customer service, it was a SFR branded phone and I flashed it with a generic firmware.
Locked bootloader, sfr gave me unlock code for sim cards, lost my root with last upadte too.
Any help ?
Did it also occur on Gingerbread firmware?
Didn't try with GB, it happened when on ICS .562, SEUS update to .431 didn't fix the problem.
I have the same problem with my Xperia Ray.
It already happened on GB and now also on ICS.
The screen stays black if you try to wake it up after standby (doesn't matter if power button or home button ).
This happens around 80% of the time.
The only things that help are: Waiting a few minutes, taking out the battery, or hitting the power button like crazy and eventually the screen will show up again after around 10 times on and off.
I brought my phone to the service center of the shop 3 times and every time they tell me they won't repair or switch it because the hardware looked fine in their opinion (they don't switch it on there, the one time I showed them the switched on phone with the error, they told me they could see the problem but as long as nothing inside is broken 'it's not their problem' . I told my lawyer and now he is trying to get me a replace phone.
The problem even comes right after you factory reset so I don't think it's an app.
It happens without the sd card in.
I had an different homescreen launcher installed around the time it first happened, but I removed it and it still happened and I factory reseted and it still happened. So I think it has nothing to do with that?
I tried software repair with the SE Update Service and it told me everything was alright.
Does someone around here have an idea what could be the cause?
I brought it to SFR customer service (here in france) 2 time, the 2 time they just downgrade it to GB, diagnostic was "update problem". They didn't take in consideration what I told them.
One of the shop employee told me that the third time normally they have to replace it by another one. If they don't want to change it I think I'll mess up their shop...
This even happens on Xperia Mini
when ever i try to wake it up by pressing Home button or Power button
it takes about 3-5 seconds to wakeup
it should be instant isn't it?
I also experienced 2 times that even pressing
all the buttons doesn't wakes up the screen
but only back light, then i have to restart the
phone by removing the battery.:crying:
Me too !
I have tha same problem !! I can't take it esay..It's bad thing in my Idea! very disgusting :crying:
I've got the same delays on my Lww, sometimes my phone doesn't wake up at all, and sometimes it takes several seconds. I haven't found any solution for it, but it seems to be a Sony-specific problem.

I turned the sound for messages and phone calls back on. On 'silent' the phone just vibrated.
It hasnt fixed the problem of the black screen completely, but it is happening a lot less for me.
Finally I brought my Xperia Ray to the shop where I got it for the third time.
I bought it 159 Euros in december 2011 (plus Sony gave me 50E back) and they refunded 270 Euro in november 2012 !
Not exactly a refund because I had to choose another mobile, so I took the Xperia T which was 430euro, so I had to pay 160 E for the XT.
Good deal for replacement of a one year old mobile ! Only problem is that I can't unlock the BL.
It is a strange hardware problem since the screen can eventually be turned back on, so maybe it is something in the firmware that is screwed up and doesn't get completely fixed by SUS. If I were you guys I would try this fix: http://forum.xda-developers.com/showthread.php?t=1492805
It may not work, but it is better than throwing your Ray in the trash.
I have the same problem. My phone (xperia ray) after standby or after reboot has black screen with backlight. At first waiting for couple of seconds and trying to wakelock would solve the problem, after few weeks to wake up my phone I needed it to reboot (pulling out the battery). Now I need few reboots to start the device with screen on.
I found workarounds like Llama combined with Nightclock (both from Google Play) for the screen never goes off, but this eats battery and also sometimes the screen would go off. I don't believe its a hardware problem because with this workaround the phone is usable few days (until Llama delay the "events").
Found a way to make a logcat from starting the device. Two are for unsuccessful startups (black screen with backlight) and one for successful (screen on).
I think the problem is in the kernel for not loading drivers, but someone who knows to read logcat will tell us/me for sure. I can't flash new kernel because the phone is with Bootloader locked (Bootloader unlock allowed: NO).
Kernel version is 2.6.32.9-perf
Stock Rom 4.1.B.0.587
rooted
PS. Sorry for my english its not my native language.
Just to add one or two more informations: even with black screen and backlight the phone is usable, like I can answer on calls, it vibrates when I slide to unlock... I also thought the problem is in proximity sensor, but if it was that case the touchscreen would be locked.
If you fully discharge the battery and after switch on,it start normally?

hello.
I've got serious problems. Today I get in the car and watched the latest messages on my phone. then suddenly the screen began flickering and everything was getting over bright. So I thougt that a reboot would help. totally wrong, Tried to reboot but the samsung boot screen turn purple with blueish tinted letters. Then my heart goes crazy because I tought I bought a phone with a decent quality. And now the screen is just past away!! Why Samsung, Why?? Tried to boot several times. Phone starts up so I made a backup from the SD card but there's no working screen. I feel horrible now. because now i have to wait untill it's monday so i can call Samsung for an RMA and then just wait a couple of weeks. 2 weeks without my S3. This is just like rehab in a nightmare...
Does somebody here have experience with a faulty screen?
p.s.
Phone never dropped on ground, never. Always have TPU case with touchscreen-protector

will it be covered under warranty? On a dutch forum I read several cases with broken screen. most of them in a couple of weeks after the release.
If this will be every 5 months I want my freaking money back because I don't gonna sent my phone 4 times in 2 years. and after that I have to gonna pay myselve for the repair. That's rediculous. Even the S2 would last longer. This is such a shame for samsung. Monday I will call customer service and then I will explain the whole story and then they have to repair it as soon as it gets.
I have the flickering screen problem as well. It happens when the screen turn off (time-outed and manually) and turn on again. Anyone has the same problem? I wonder if it is a hardware or software problem?

If you screen or display is not working its warranty . If your screen is broken or cracked its not warranty .
If you have custom rom or root or rom counter above zero warranty is void .

Not dimmed actually, The screen is like the magnetic field noise when we put our dialing cellphone near to CRT monitor last time. Sorry for my bad english.
they can't even see the binary counter because of the screen that's broken .
But I think I did reset my binary counter already 2 months ago. after that I only did flashes with CWM. Not Odin.
p.s. Does it count flashes with CWM? I think it only counts when you load via odin.

No I'm serious.. How can they watch binary counts when display is not working anymore?? Simple right?? Here in the Netherlands there are several cases with people that have rooted S3's with broken screen. They all get a new phone. If they could see the binary counter. They wouldn't send out new phones right??

Hello, same problem here but only when auto brightness and power saving mode (any combination of options checked) are on, which I just recently noticed since on dark background you wouldn't see it. Software bug?
