It figures something would happen to my device after the warranty expired. The touchscreen developed a fault and now has a dead zone on the right side from top to bottom of the screen. This fault affects the ability to unlock the tablet, though if I press down hard enough I can get the tablet unlocked. However, most other functions are affected. I'll be disassembling my device to see if it's something simple on the motherboard, but it's a good bet it won't be something simple, so I'll be in the market for another device, likely a Lenovo A2109, since it's in the same form factor.
