This new . 142 update that's has come through
I don't know what you have done but now the phone is loosing reception regularly.
It literally looses the reception for a minute and then finds it again. At one point it even rebooted it self
I'm on the telstra network in Australia.
Also VoLte seems to have stopped working now too.
OK it looks like the WiFi calling option is causing an issue in this update. When I enable it I experience reception issue. Also VoLte icon disappears etc. As soon as I disable wifi calling everything seems to be ok
Same issue here, the latest update seemed to enable vowifi, but it doesn't work. Every time I connect to a wifi my mobile connection drops and reconnects constantly, draining the battery in the process.
I've turned the wifi calling feature off and it seems to be working fine.
I called Telstra and we tested it on another device, wifi calling is working fine on my old device.
Also called Asus support, they were pretty useless and just recommended to do a factory reset.
