hye. i just bought samsung galaxy s advance 3 weeks back.
the overall performance is good but there's something annoyed me
if i dont reboot this phone for about one day, whenever someone called me i cant hear their voices. just pure damn silent but the call is still ongoing but when i restarted this device, everything goes back to normal.

and not to mention it will become lag after 1 full day usage forcing
me restarted it every night.

please help me dear sifu s advance. should i root it or does it
have anything to do with internal hardware?

ouh really? haha. no wonder la, i always installed apps from blackmart. will try factory reset first. but if i root the phone, will it do any good?

just do a factory reset. problem solved. make sure you backup all the data
via kies to pc

yes. just after 2 days i bought the phone. now problem solved hati pon manyak senang maa
