If you ever come across a situation where your Moto Z (or Moto Z Force) forgets it’s got super cool 4GB RAM and Snapdragon 820 processor under its skin, and hangs on you, such that screen becomes non-responsive and utterly useless, well you need to restart the device, albeit forcefully because you can’t choose the power off option anymore as usual.
To force your Moto Z to reboot when the screen hangs, do this.
How to Force Reboot Moto Z, Moto Z Force, Moto Z Droid and Moto Z Force Droid
Just press and hold the Power button for 10-20 seconds continuously, until your Moto Z ‘s screen goes off, and when it does, it should restart.
When the device has fully powered on, let it rest for 3-4 minutes before putting it to use. It should work cool now.
→ If you installed an app recently, make sure that it isn’t causing the device to hang. Uninstall it if it does.
