I have problem recording on "whatsapp"

Hi,
Its started not long ago, when i record a message in whatsapp randomly its stops the voice after couple of seconds, can be 2 seconds and can be 20 seconds, but it keeps recording with no voice.

I checked if i have a problem with the microphone and there isnt, i looked in the internet and didnt find anything.

Please if anyone can help, i deleted and installed whatsapp and still..

Thank you
