After booting up the Z8 for the first time everything went smoothly.
All the settings about country, wifi and so on wasn't any problem.
When that was done and the device entered the android OS this screen appeared and the device turned off.
When firing it up again (from standby as it appears to go to) the message did NOT appear.
The error message says,
System shutdown initiated
Reason: Returning to last known power state before AC power loss.
Press BACK or OK to cancel automatic shutdown.
I've tried factory resets, no extension cables and so on without any luck.
Still the same error message.
It's a brand new device so.. most likely a warranty thing.
But. has anyone else seen the problem?
