i can't make a call in whats app or face book or viber the other person don't hear me but i hear him the other calls and the applications work well how can i solve this problem
So you went to settings, apps, and clered the cache, you did this on what device because I don't see that on my iphone or in whats app. Be more specific on the device you talking about please.
iPhones will have totally different settings. It's irrelevant to try to apply any fixes you see here to an iPhone.
Caller can not hear me on whatsapp
