I have problem with my Sony Xperia J
After updated from ICS to Jelly Bean, the ringtone cannot be saved, I mean, after for several turn off, it always become unknown ringtone, when the calls come from my friend, only vibration, no ringtone, this is ringtone issues
and the battery is also drained faster than before, this is really dissapointing update, what should I do to fix this, or Sony have the new update to fix this?
