Having the same issue.
After a call the screen is turning off , not even having a back light, and can't be turned on.
The screen and the touch are both not working, but the phone is still on.
Can only force reboot it holding both vol down and power buttons.
@Gustav_ASUS can you please move it forward?
The phone can't be used that way...we can't hard-restart our phones every call or two, this is actually the main purpose of a phone - making phone calls
😅Have already tried to wipe the phone and start over with a clean installation, unfortunately it didn't solved the issue.
Looking forward for your response,
Thank you
