========================================
I am facing a huge problem with my asus zenfone max pro m1. Today Morning I've received a fota update regarding May android security patch and APN. After the update ,during Whatsapp or any other app video call the microphone doesn't work. I also checked if there is a problem with my microphone during call and audio and video recording and there is no problem with my microphone. Also the audio speaker volume is low. All I did the may security update and this happened.
After the update I am not able to make whatsapp video call and zoom video calls and any other app video calls (I have checked it with duo and google meet and the microphone doesn't work!!) in this lockdown situation! Please help me to resolve the issue. Please...
