I am facing a terrible problem of microphone in my Xperia ZL for nearly a month now. The person on the other side is not able to listen to any word i speak. Total silence unless i speak very loud in front of the mic. I tried Cleaning the microphone hole with a needle but doesnot help. Any suggession on how can i solve this issue. Service centre is pathetic where i live and dont want to give it to them. I tried restarts, repairs via Sony PC companion, factory reset, everything. Please help me
