KOReader randomly inverts user orientation preference after page turn, and requires the user to re-orient the device 180˚ from the selection appearing in the lower menu.
PB Era 6.7.775: KOReader 2022.07
I've disabled the positional sensor in the Era but it still happens.
Typically this problem occurs one day after launching KOReader.
Re-starting fixes the problem (for about a day)
Note that the Era FW version 6.7.775 has some orientation issues of it's own, for example, when you set the orientation for left handed use (buttons on the left) the home screen and the Logo screens are upside down. If you use the positional G-Sensor", the home page is correctly oriented, but the Logo / Power off screens are still upside down.
