i have s3 i747 at&t.
after upgrading to StockMOD ROM 4.3 rls 2.1 (from rls2) my speaker started to make crackling sounds and sometimes even very low siren sounds. so i tried to go back to rls2 but it doesn't help - the sounds continued, so i decided to go back to stock and now not the camera flash or the speaker working.
can some one help me?
here is some things i also tried:
1. to put the speaker in another phone and it worked perfectly.
2. the aux (headphone connection) works perfectly.
3. to install a new speaker in the phone and it won't work.
4. factory reset.
can some one please give some ideas about what might be the problem?
Has root, unlocked, S3 i747 from At&t, Stock rom on 4.3
