Hi there,

I am using the V20 with Android 7, I got an annoying problem lately. I installed a voice recorder for recording phone call and it worked great until last week, the app failed to record any voice, I tried other similar apps but none of them worked, and I found Whatsapp refused to record any voice at the same time, all worked again after reboot but the problem returns after some use, so it is the OS itself to blame but I couldn't find a way to fix that, any comment ?
