On my older Samsung Galaxy Tab 2 (GT-P3100) with Android 4.1.2, which I only use for messaging, both calls and videocalls start to get laggier and laggier the longer the device is running. If I make a call immediately after rebooting the tablet, both audio and video are streamed perfectly to the other device, but, after some time, they start to get worse until the call drops, usually with the message "Call ended because there's a problem with your phone's microphone. Try restarting your phone and try again". Is there something I can do about it?

  • "Samsung Galaxy Tab 2 (GT-P3100) with Android 4.1.2" is your answer. Requirements are much different that what they used to be when that hardware and OS where current. Jul 20, 2021 at 14:48

Maybe try removing useless touchwiz system apps using adb so that the device gets a bit lesser workload.

Speaking practically, I'm afaid it's time to give up on that device - Ageing is the reason the hardware is degrading ; nothing could improve it
