Call receiver sound low

[Cyvasse]

Hi! My wife has been using this phone for 10 days. First days it was all OK but suddenly sound during calls started to be very low and I cannot ta make it louder. It is hard to hear th e opposite side talking. When listening to music or youtube everything is OK. I have entered enginerring mode but all can I do there is to test sound, cannot change levels. I think it's maybe a software problem. i ma on o Chines stable ROM 7.1.2.0.

Thanks for ideas, it's really a great problem because you cannot talk to other persons normally

Have you tried to re-flash it? or maybe change the sim to a different card or carrier?

I so thought to change SIM card, will try it and report result. Also I'll flash ROM with root and see what happens

Today I put my SIM card and sound was OK, but when returned wife's sound decreased again. Maybe factory reset or get another SIM card from my operated will do the work
