I tried one out for a short time and returned it. If I recall the jelly scroll was due to the way the screen physically refreshed, and unless they changed the hardware completely, it was not solvable. I also had issues with my unit where pressing even slightly on the screen, like normal tap usage, caused some sort of big light distortion. Also not having face unlock is a big deal for me, I love being able to just tap the screen and swipe to unlock. Hoping they stop locking that “pro” feature behind an artificially inflated value.
