If it didn't work on v20b it's a hardware failure and therefore the warranty still persists. Just flash back an official stock firmware and send it to LG.

Its not a hw issue that they can fix for sure; they will probably just reflash kdz and be done with it.


Issue seems to be caused by VoIP programs somehow. For me the culprit was viber, for ezet skype. No fix, other than flashing a different rom, and hoping the bug doesnt appear again (i had this issue on 4-5 separate roms, including stock, so its not related only to custom roms)

Yeap, happens to me too. Only quick solution is to open the speakerphone, if the other party hasn't already closed the phone cause they didn't hear a thing..

Same issue on stock rom
Hi, I have official JB 4.1.2 stock rom (v20c), and I experience same issue from time to time. I have sent an email to lg support, hopefully I will get some useful answer, which I will post here. Did not try the speaker on/off workaround, maybe it will work for me, at least I wont have to redial all the time...
