Default Xperia Ray Call Problem
Today there has been something weird on my phone. I haven't done anything with firmware recently. Last it was ota brick and i fixed it. Today someone called me after i finish the call screen didn't came back. I mean it was like locked but not unlocking with on/off button. I was using 2.3.3 version. I flashed it with wotanserver. (2.3.4 version)

Please help.

Edit: I just had a new call. It is not shutting after call. It is shutting when i answer the call. And phone is not sutting down. Just screen is not coming.

Edit: I am really sorry about this post. I totally forgot that there is a light sensor top of the screen. There was a sticker I removed it and now it works. You can close this post.
