To change the language, from the Home Screen press the Menu button & choose the bottom right option. That's Settings, then choose the option with the black A on a white background, it'll be about 10th on the list. Choose your preferred language & you're done.

You can then properly look around your Display settings, etc.

How did you upgrade it? Kies, Odin, Over The Air or through installing the firmware from your SD card?

I ask because if it's a full wipe & recover, any settings that you had would have been reset. If that's the case & the problem is still there, I'd suspect a hardware issue such as a faulty proximity sensor.

Start by downloading Phone Tester from the Market. Open it up, go to Sensors & look at Proximity. Put your finger over the sensor, then remove it. Is the app saying Near when your finger's on it & Far when it's off? Does it keep saying Far if you keep your finger away? When you click on Properties, what does it show?

I'm convinced that it's a hardware fault mate. From what you've put there the proximity sensor's working fine, but maybe a logic circuit?

The only way (in my opinion) that it could be a software issue is if an app is causing it. Can you remember if the problem existed straight away after you flashed it? Or was it after you re-installed your apps?
