Hi,
It's not a software issues, your battery is just over discharged, so it needs a longer time to be able to be charged properly. Check your charger with another device and if it works properly, leave your Z1 on charger for about 12 hours.
Nope not that either. It died when it was on about 80% charge (was charged the night before and died about 30 mins into the drive) Then when we got to our destination and I had a play with it I left it on charge over night and it is still having the same issue. NOT a battery discharged issue.
Charger works fine everywhere else.
Noticed this as soon as I setup the phone. I don't think I've ever seen an panel do this. It's almost like it's refreshing each line of pixels too slowly/unevenly during a single frame?
Text and elements on the screen stretches out when scrolling down, and smushes together when scrolling up. Straight lines look wavy when scrolling left or right as well!
