Screen Flickering. Is this normal?

[victorvbc]

I think it's more of a redraw problem than the screen itself failing (the LCD passed the test on recovery mode), maybe I used the wrong term. The calculator does seem more unstable since I did the 2018-10-16 firmware update, I saw it crash and clear memory a few times.

Found this thread later here in the forum: http://www.hpmuseum.org/forum/thread-101...l#pid91020

So maybe it is a common issue?

Edit: Another thing that has been happening is the calculator resets itself after coming out of low power mode (hold shift + off) every time, which causes me to lose all my programs. I can see "Your HP Prime had a problem and will reboot in 3 seconds" when it tries to boot, while the backlight is still off.
