Root [International] Screen goes blank / black

[Beatnink]

Hi, I've just bought a Galaxy S3 which I had upgraded by the parallel importer to Jellybean 4.1. All works fine except that when I do any of the following the screen goes blank / black:

• drag an item around the home screen;e.g. hold down an app icon and try to reposition it. Screen goes back to normal after a second or so
• open certain applications;e.g. when I open the Klondike game, it briefly shows the splash screen then goes black. I can press return to get back to the homescreen
• try to make a video call in Skype; call continues but screen goes black. Goes back to normal when I press the return button

Not sure if its an Android OS or hardware problem. Anyone else experienced this? Any suggestions?

Cheers

Welcome to the forum Beatnink.

Did you wipe your phone after upgrading from ics? It could be caused with leftovers of the old firmware interfering with the new.

I had the phone upgraded to Android Jellybean by the company that I bought it from. Perhaps a case of reinstalling it all? In which case, any tips / links for how to do this in the most easy way? And is it worth installing the official release or continue with a root (if that's the right phrase? I'm a newby to this)

Could you go into settings, about device and tell me what it says under build number please

Thanks for your help! Really appreciated..

That firmware is a leaked version so it will contain bugs. I'd recommended updating to the official release

Sounds like a good suggestion. Does it matter what the region + country is for the stock official firmware listed on the xda-developers.com site? Thanks again.

Nah. The country doesn't matter, all firmware for the i9300 will be compatible with every i9300.

A belated update. I haven't flashed my phone to the official firmware yet. I was about to return it to the web store I bought it for, for them to fix it under warranty. I had another go at resetting the phone first. This time I didn't get the screen problems, and I'm starting to suspect that Go-Launcher EX may have had a hand in it. I'll contact the developer to see if it is a known problem. But thanks for the help, suggestions so far!

The webstore I bought the phone from has updated the firmware and so far I haven't encountered the problem again. So hopefully end of the problem.

The new firmware is
Version = 4.1.1
Baseband version = I9300XXLH1
Kernel_version = 3.0.31-41218
Build number = JR003C
