Hello,
I'm using Samsung s5230 phone for 1,5years, but now I have problem. So he is the story: One day my back cover broken a little so it was falling from the phone. I glued it to the phone with super glue and one day I had to remove the cover. It was hard so I hit the phone to the wall few times not hard. Everything worked good after that till today. I don't know how but I ripped of a corner of touchscreen cover and my screen became not responsful. It doesn't react to touch, but shows normal and 3 buttons under screen works. When I strongly push the ripped corner back to place then screen works but I have to hold it. Now holding that corner doesn't help.

Does anyone knows what to do?
Sorry for my bad English :(
