I bought Galaxy SII about two weeks and every was so smooth and a happy user until recently I received a call and my phone went to flight mode automatically after 50 seconds, then I had to switch back to normal mode and made a call back. The duration was about a minute or two and then the screen went black which was supposed to come back to normal and after pressing the power button then the initial start up screen appears and everything on the screen was distorted like a broken display. I then quickly removed the battery and started the phone again. The phone seems to be working fine till now, but this is not a good sign
Can anyone explain what actually happened about this inappropriate behavior? I very much worried about this.
Thanks in advance,
