When mine crashes, sometimes I have to remove power, others it reboots.
It’s a memory leak, it gets slower after some time (of use or idle/sleeping) and then it crashes and stays unresponsive… other times it reboots.
I think it reboots to power on, but I can’t remember.
I’m using a remote control to a power on/off switch, so I can use the unit.
In previous FWs, this only happend to me when using apps like youtube leanback.
“3 Hours energy saving auto shut down = on/off”, was also working for me in previous FW.
