I switched back to the old 11501 firmware because a encountered a serious problem with the indian firmware:
When music was playing through headphones and I received a call the music was not muted but put to maximum instead for moment. That totally shocked me. Furthermore, I tried the TuneIn Radio app and it was even worse. Regardless which volume level was used the music output was always at maximum. I don't want to ruin my ears so I'll wait for the official german update.
Did anybody else have the same problem with the indian rom?
