everyone says they can barely hear me
the person who calls me or the person I call all say I sound like Im in a tunnel, adjusting the volume does not help. also some calls I make or receive say HD, why?
That's mean your mobile operator enabled HD voice facility and i guess that is fault which you experiencing. HD voice working only in 3G/4G network modes. you can solve the issue switch to phone 2G,
setting > More >mobile networks > network settings > enable "Use only 2G networks
Most of HD Voice issue coming from mobile operator and escalate case to them
OK when the phone says HD on in notifications double click it then press info then double click it again and force stop it everything works fine for me now
I was having this problem as well. I checked the microphone with a flashlight (which is the small whole that's at the bottom of the phone, next to the USB port), and I noticed that there was some crap in it. I used a needle and removed it, and that did the trick. People can hear me perfectly now. BUT BE CAREFUL NOT TO GO TOO DEEP WITH THE NEEDLE, you might damage the microphone.
The mic could need to be replaced. More likely than not its a hardware issue with the phone. How long did it work before it started ? And does it always happen now or sometimes not?
Speak into the holes at the top and bottom of phone that's where your mic is. Or clean the area where the holes are they tend to get clogged with dust
Microphone are the holes at the top and bottom of the phone they tend to get clogged with dust. You may use a small pen needle or blow air into the holes. This actually work with my phone which is a ZTE XL.
My friend had been having trouble for months. Today he determined that the mic is on the back so you have to hold the palm of your hand over the screen instead of the back.
Got new phone last week but mic does not work. No one can hear me. Just bought another phone today and have the same problem. Mic not working. Bought both ZTE Z233VL. This problem needs to be dealt with.
I fixed this problem on my husbands phone in a really unusual way. I put the phone into developer mode and disabled automatic routing to usb audio peripherals and bluetooth audio peripherals. Here’s the unusual part: The phone was second hand and the neighbours bought a new car. The new car was a make it had previously shared a bluetooth and USB connection with. Even though blutooth was off the ‘automatic audio peripheral’ function seems to have divided the phone’s audio potential in anticipation of connection.
