Purchased used on Mercari in November 2024 and used for about 6 months.
The touch sensor on the right half of the screen in portrait mode stopped responding, making it impossible to even unlock the lock screen.
Although a forced factory reset was possible, the sensor did not improve, and the right screen did not respond even when powered on, making initial setup impossible. When I tried to sell it as a junk item on Mercari, I learned about the existence of FRP lock and the ability to operate with a mouse. After performing a factory reset, not only was the FRP lock removed, but the malfunction of the right screen also recovered. I used it for a while after that, but there are no particular problems, but I have already purchased another device and no longer need this one, so I am listing it for sale.
