Hi guys,

Whenever I receive a phone call from anyone, the callers are hearing a noisy echo of their voice as they speak. I tried many things to troubleshoot this issue as below:

- Hard reset the phone.
- Put the phone into the SAFE MODE.
- Check all the call settings searching for any relevant option, like: Noise reduction.

Note that I'm using Samsung S6 Edge+, with Android Marshmallow.

But I noticed something which is very weird, when I'm on an IM call, I don't face this issue, like when I'm calling someone in Facebook Messenger, or Viber. It's happening only in normal phone calls!!

Regards
