I own an A925 with REL 30.80.20 firmware.
From time to time I cannot hear any calling sound in the earpiece only if I activate the speakerphone then I hear the conversation in my speakerphone, and that is annoying because if I am at school and I'm talking with somebody that person hear any sound in that room and anybody in that room hear what I'm talkin at my phone.
So please if anybody have the same problem and fix it please help me. 😊
