Hello.
I just bought M7650 last week. For the first few days, everything seems to be working fine. The device has been really smooth and I love it.
Recently, whenever I woke up from bed or went to make myself a cup of coffee (3-5 minutes). Upon returning to my desk, the display screen isn't showing anything after pressing the menu or power button once (waking it up). It was only showing an empty screen with its backlight turned on. The backlight will turn off automatically a few seconds later. I had to reboot my device in order to see my menu again. The device is still working as usual, the internet is still connected. Nothing is wrong with the connection. The only issue is with the empty LCD display screen upon "waking up".
I tried to update the firmware from the cloud, it says: Server error, please try again later.
I have also tried resetting the device twice and the problem is still there.
I'm pretty sure this is a software related problem because the hardware seems to be fine.
Here's my recent debug log:
