It dropped on the ground a few times and now the buttons don't work only the end call button works.I had a guarantee and i did take the cellphone to get it repaired but they told me the reason it isn't working...because it dropped on the ground and they ended my guarantee and they didn't even fix the phone -.- gay isn't it?So i tried removing the battery and sim card for a very very long time...then the cellphone starts working for a few seconds and then again all the buttons stop working....any other ideas?Only the end call button works.....
