guys I got a problem wif my sgs2......I alredi stated my problem awhile a go....n tried to fix it but...I think i'm out of luck..... this is my problem:

Whenever im playing my music while using earphones n lock my screen off....it tends to hang...n the only way to make it working again is to take the battery out or by clicking the power button for a few sec....I tried factory reset, using other media player, using different earbuds......the weird this is...it only happens when i put the earphone on....

Any suggestion guys?....really need help here....^^

No not really....I don install any sound/dsp effect apps....as far as I remember.....

Im kinda NOOB about customizing android phones....the only thing I do is jus installing apps from market....n ....thats about it i think .....no I din undervolt my phone....
