My daughter has a Moto Z2 Play and it will randomly shut itself off. It's not a battery issue because when you get it powered back on it will have anywhere from 40% up. It's an instant shutdown. To get the phone started again I had to hold the power button for about 10 seconds. This just started within the past week or so.
I checked to see if it needed an update but it showed current.
It happens both Wifi and network.
It has happened in multiple activities...listening to music, VOIP phone, regular phone, no clear pattern.
Has anyone had any odd issues with random power downs like this?
