SInce today, it seems my media player is not working. its opening, i can see which all media are there, but the songs are not playing, the videos are too, like stuck.
i switched off, removed battery n put it back, no change.
i did master reset, no change still.
the problem disappears when a call comes(or missd call), it rings. then immediately if i try, media works. once i exit, and retry, its stuck again.
same when i change ringtone volume. after i play ringtone, music works, after exit, problem persists.
any help? tell me why this is so?
i am really sad.
