Who else noticed the problem with hands-free calls? When I switch to loudspeaker, the caller hears only me, as if "muting" the child's voice. Only when screaming directly into the microphone is it barely audible by the recipient. The problem appeared both during a standard phone call and through the application, e.g. Whats App. Weird - sometimes it works, sometimes it doesn't. Any ideas, tips? Maybe someone from Asus officials will refer directly?
The noise cancelling on this phone is definitely faulty. On-ear the noise cancelling is almost not existing like the other person hears everything that's going on around me but on speakerphone it's way to strong like you described! It would urgently need an update but this has been discussed here several times - ASUS doesn't care anymore.
