Most of the time my illumination bar stays on even after locking the device or wait until the screen goes off (sleep mode)...so my battery drains real fast...help!!
Solved! Go to Solution.
I got the same problem after JB update and I uninstalled illumination bar in order to save the battery power. 
I have this problem too! It sometimes goes off but the rest of the time the LEDs stay on full power after pressing the lock button and having the screen off. Totally draining the battery!
do a hard reset
Without sounding stupid.. how do I do that?

Didnt work:/
i had the same problem, i uninstalled illumination bar notification and then restarted the phone. Issue resolved 
try this now *#*#7378423#*#*
Just to clarify for other people, Illumination Bar Notification is not a Sony app, it's one downloaded from the Play Store. Uninstalling it has fixed my problem!
