Hi, i just solved speaker problem. I did clean up speaker grill from all debris using fine bristles brush. Speakers grill opening are to small and easily get clogged. Now problem solved and I'm happy with my low budget solution. Thanks
I had the same issue, one day my calls where just quieter. Tried updates, restart etc. But I found an effective fix. Once you are on a call, not on a headset, click the 3 elipses on the top right of the call controls and click "enable extra volume". Worked for me, call volume back to "normal". I guess I lent on the phone with my ear or something to disable to extra volume without knowing it.
After trying all the reset solution boot to safe mode etc I sprayed electrical cleaner CRC in the ear hole at top of the screen (switch off first) and the loudness and clarity is now amazing. Simply a blocked port.
All things just waste of time .. i have same issue ..i try to update my cell 3, 4 time .. then i reset it 3 time then i update it 2 time . But no response. Then i visit a repairing shop ..he gave me estimate of 120$ to replace ear peice but after all i try to clean it By Petrol with a tooth brush .. its make it ok... i feel very happy .now its like new.. in this some carbon block voice & petrol remove it off.. its good solution
