I almost shit brix today thinking my phone already broke,
was using qiblat finder app,

the compass needle doesnt move,
then i open nokia city lens also doent work,

perform hardware test, confirm already my directional sensor doesnt work anymore..
after half hour, i almost wanted to reflash the phone, maybe it will help before i send it to nokia...
then after that, i realized my flip casing got magnet! Haha, i almost forgot, lucky havent format it or send to nokia, if not waste money and probably kena laugh kaw kaw by the staff..

when take out from cover, my compass works again..
so, everytime u wanna use compass, dont forget to take out from magnetic cover...
