just updated to version 31, i found it to be more responsive when pressing, about performance.... can't really tell the difference yet, but i haven try on gps

hey i wanna ask a noob question, what is the advantages of doing a 'hard reset' rather then just off and on the phone? Cause i have just updated my firmware to 31, my phone is working fine, but would be it work better if i 'hard reset' it?

I have experience some problems with the phone, it's nothing to do with the hardware or the firmware, but rather the battery notification on the top right corner. The battery bar is not accurate at all, eg. I use to listen to music for about 4 hours straight, but then the in the next 12 hours, its still on full bar, but when i restart my phone, the battery drop straight to 4 bar, I'm just curious, is it the firmware that causing the inaccuracy, or the theme that I'm using? Has anyone encounter this before?

version 31... still having the same problem T_T
