[Please help] My techno spark k7 has mouthpiece problem
(05-03-2018, 03:34 PM)Jennie Whenever I make a call or get an incoming call, the person on the other line can hear me but I can't hear them. I took the phone to an engineer and got the mouth piece changed but after 2 normal calls, it's back to the same issue. What should I do?
