Critical Screen Problem! - Galaxy S II Q&A, Help & Troubleshooting

""Hello friends, without any ado, I would go straight to my problem!""
I am a flashaholic and flash my i9100g every now and then whenever there is a new update for my ROM.
After about 12 to 13 flashes, I am getting this screen problem..... After switching on the phone, for 1 to 2 seconds, my screen flickers with horizontal colored lines!
CHECK THE SCREENSHOT!
AND PLZ HELP ME A.S.A.P.!!

Back to stock, test. If OK with stock, clean install of custom rom, test. If obvious problem with custom rom, ask the dev of said rom.

Thanks
Thanks a lot for your quick reply, but I've tried installing the stock ROM...... maybe I'll ask ryuinferno
Anyways, thanks!! :good:

If it's happening with stock it's a hardware problem. Take it to mobile repair shop (or a Samsung service centre if it has warranty), or replace the screen yourself if you're confident enough & are able to definitely diagnose it's just the screen that's causing the issues.

Ofcourse it doesn't have warranty becoz its rooted and the counter says 15..... so SAMSUNG PEOPLE will charge me if i repair it......
Maybe I will diagnose it a bit more and see if it works!!

Problem solved!
Thanks to ryuinferno! Actually, I was using a ICS bootloader..... All i needed was a JB bootloader which i got from this link: >>Repository<<

What do You think, is it hardware problem or software-!
I can't get new replecement, as I'm in other country right now...
I had unlock code from T-Mobile-!
If i try to flash custom roms, will it work-?
Thank you for your advise Shahr-!
could be overheating (few+ threads on the topic here on xda), if this is the case, then shahr321 is right - mainboard replacement for you,
to check if overheating: let your device cool down a bit (10 minutes in the fridge helps), then start it, install BattClock, set it to display battery temperature and observe if freezes happen at/above the same tmeperature

After 10 minutes HD2 turns on, and works fine, but when i start camera recording or play games, it's freezes again, Sence freezes to after few minutes...
Camera can record only 30 sec of video, after that HD2 gets freeze again-!
I used to think positive when anything happen. i always do this steps, first soft reset, if not helping then i do hard reset and if it's still doesn't help finally i do flashing stock ROM. Other than those steps then i'm sure it's hardware problem..it's time to go to nearest service center.

We do not have service centers in our country, so i need to fix myslef-!
Flashed Radio from 2.15 to 2.12, much better, but still freezes...
I'm in T-Mobile's stock ROM, it's newest ROM, so i can't update, i I can unlock via HSPL3, and flash custom ROMS, what do you think, will it help-?
P.S. I made Hard Reset, but same problem-!
flash custom ROM, if that wont help you gona have to change touch screen (digitizer)
it's common problem

********* Ok, so how is replacing the screen or digitizer going to help with freezing and boot up issues? Not being cynical just curious since I am new to this. Also do you have to replace both screen and digitizer or just digitizer?
Mine will not start ever unless it is coming from freezer. Cool (0-4 Celsius) phone starts just fine in WinMo or Android (I am on Android now) but as soon as it gets worm it shuts off and becomes paperweight.
Any help you can give would be good. Puno Hvala
Bro flash a stock rom... shippedroms.com

(first try to remove MEM card) it worked for me.
I had the same problem I read on the forum the HTC was giving type 4 MEM cards bc the freezes... however i bought one 4 gb type 4 and no more freezes on WM and Android.

unroot and revert to stock problems.

Hi,
How do I 100% revert to stock ??
I can flash a stock rom via Odin and lock the bootloader. if I do those 2 things .. is my tablet 100% stock again??
I'm having some problems which I believe are not really custom rom related.. So I wanna check by putting it 100% back to stock first.. and if those problems still exist RMA the poor thing..

Hello,
I had my tab sent out for repair (screen came loose), and got it back with bootloader unlocked....
But yes you can flash stock and send it in for repair.
Whats the problem if i may ask

The screen is all messed up .. when I turn the device on .. colors are a bit fuzzy.
But after a few minutes .. lines starts to go through my screen and later on there is nothing I can see except running lines and dots running to the screen in different collors..
Strange thing is .. it also does this on the splash screen, battery charging screen, clockwork and even the bootloader screen :S...
Like my tegra2 chip is fried :S ...
I remember seeing something like this back on my 8800m geforce card .. Turned out then, that the gpu chip's soldering was just bad and it needed to reflow.. Back then it was an issue with the type of soldering nvidia used, the whole serie suffered from it..
But first off all.. I guess Nvidia learnt from that.. Second of all .. I haven't really come across others with this problem on the p7100 :S ..
Strange thing is ... I haven't really changed anything on my tab the last few weeks. I'm not overclocking..
The last few days I did notice some pixels of weird colors on my wallpaper, but I figured it was just a bug in the livewallpaper which I installed a day before (skyrim live wallpaper from the tegra market)
I dunno what happened of what exactly causes this .. but it does really sting :S..
Try flashing (stock) rom, maybe that will fix your problems.
But by the sound of it it doesnt look like a rom problem....
Sent from my GT-P7500 using XDA App
Indeed thats what I figured...
Other then locking bootloader and flashing stock.. is there any other way samsung could see my device was rooted??
The thing is.. I don't overclock because the device is fast enough and I prefer battery time over extra performance. But .. if the tegra chip is somehow fried.. Samsung could blame rooting.. Which is understandable .. therefor I don't want them to jump to false conclusions.

[Q] White line on screen on

Heya
I've been searching around and havn't found any issues like this
But granted it's hard to describe and thus hard to search for
My Galaxy S2 is new (A few weeks) yet since new has had this issue. When powering the screen on (Lockscreen) the screen displays a white vertical line just left of the middle of the screen before powering on.
This line is NOT visible at all at any other time. Ran some screen tests without any evidence. Seems only to occur before unlocking
I have compared it side-by-side with my brothers Galaxy S2 so I know this isn't normal
Occasionally it will power-on normally but this is quite rare.
Had this issue from Stock, moved from rom to rom without change
Is this something to worry about? Could this be a sign of a failing screen, lose cable, crappy connection etc?
Is it worth sending it back under warranty?
The last thing I want it to do is to fail after the warranty expires
Cheers!

Sorry buddy, but It's really no prob.
It's an effect called CTR-animation (on or off)
This is an effect from an old TV turning on oder off.
So the display get crashed on a small line and goes off (CTR-off) or the display build up from white line (CTR-on)
If u using a Rom, just check ur apps for JKAY Deluxe... That's the app which manage such things.
There u can search for the two effects and turn on or off.
CHEERS ;-)

Heh thanks for your input
But it doesn't look anything like the CRT animations, nor is it pretty and well animated (And its a vertical, non-centred line. not a horizontal one
Also this was still present on the stock Samsung Rom

Oh... Then sorry buddy.
Hmm if also on stock u maybe should think about using ur guarantee (flashing on original back first, for sure).
That's really strange.

Ahhh well, was hoping I wasn't going to have to go down the warranty line
So, directly to samsung or through Mobiles.co.uk?
In the UK the seller is responsible for the warranty .
But you can go direct to Samsung .
Root or custom rom will void warranty restore to stock and reset custom rom counter .

Burnt pixels

Hi,
I just bought this second hand SII and I found out that there are burnt pixels on the screen. I added a picture so you guys can see, sorry about the quality. Anyway, I tried to run a dead/stuck pixel all night long and it didn't do much. I heard about the *#0*# menu but it doesn't work on Cyanogenmod 9. Should I flash back to a stock version to get to the menu? Any suggestion is greatly appreciated!
Thank you.
Does anyone have an idea?
IMO, return back to stock, and unroot your phone. And then try the dead pixels test. If you still feel that there are any problems with the screen, you could go to the nearest service centre. They should be able to solve your problem.

Yeah, this is what I did. I restored it to my original firmware, let's hope they're not gonna be a ***** because the phone was rooted with another kernel.
I went back today at the same time I left it yesterday and they just gave me a refurbished one in a perfect condition, I'm really satisfied with Samsung's support. If this happens to anyone, bring it back to Samsung ASAP.
I sent mine off
I sent mine off to be repaired with the same problem. Apparently it was 'repaired' but I'm pretty sure they sent me a different handset in perfect condition (mine was still in amazing condition). I'm OK with that.

S3 doesnt autofocus properly, warranty info ? HELP??

Recently my s3 has been having a wierd issue with the auto focus regards to close pctures i take with the stock camera app.
Originaly i thought it was due to omega rom.
but i have now flashed a stock rom and the same problem is occuring.
I have compared it with a friends s3 and his works perfectly as mine used to.
do not know what the problem could be
i bought the phone from Ebay brand new about a week after the phone was released.
how can i get a new handset or this repaired, how long will it take
can anyone shed any light on the situation, really frustrated as i finally found a rom and setup i was happy with (battery life etc was finally perfect and than this hardware problem )
don't think anyones gonna help me on this one seeing as i'm the only one with the problem
im having problems with my camera too mate, mines is stuttering and not focusing properly. used triangle away to reset the custom binary count to 0, Ive downloaded the off voda uk fw and im gona flash that now via odin. i bought my fone from a mate who had an upgrade but i was still able to register the phone with samsung.co.uk. Have a repair set up and all, just have to post it to the servcie centre now. Hopefully all goes well.

Glynn
