Can I get some help with my Passports Microphone issue?

Hello everyone,
I'm suffering a weird problem from passport's microphone since I updated to 10.3.1 via Blackberry Link.
There's no problem when I make calls or record videos through 'Camera' app, the microphone works perfectly fine. However, if I record voice notes via 'Remember' app, or send voice messages through 'WhatsApp', there's no voice at all. I tested the microphone with BBVE, the testing was failed. Then I tried with 'Skype', it works when I make calls, but there's no voice if I send video messages.

I tried to flash different version OS, e.g. 10.3.2.159 autoloader, 10.3.1.997 autoloader, and reload many times through blackberry link, however, this issue still exists.:crying:

Can anyone help me to sort it out! Many thanks!

Perhaps don't do any backup restores after a security wipe and OS reload... then load one app at a time to trouble shoot. There may be one app conflicting.

Thanks bro, I never do any backup restores. I'll try your suggestions! Thanks a lot!

I have the same problem, please let me know if you get to solve it bro...
