nope..clear da CACHE is da cause of da problem especially using da 3rd party apps..da solution is CLEAR ur ALBUM DATA & it working fine as usual..

i realize it after done 5 time flashing da same firmware..

bout da battery usage w/o stamina mode, it kinda power sucker if owez on mobile data..dis my battery usage after using 1 hour WhatsApps & other 2 hour in standby mode..

Go to the Android Setting (the one with spanner and screwdriver icon)> APP > All> Album
There you can find clear data!!
Thanks those who provide this tip here!!

i quite like the JB update especially the longer battery life and lower ROM utilization. i used to have easily beyond 80% utilization, now can maintain around 75%.
The main problem now is high rate of Xperia Home not responding. I restart everytime when it happen. no point to wait for it to respond which seems forever.

The phone dialer and messanger also seems slower to load!!

Anyone else face the same issue??
