Hi, I unfortunately do not have a means to contact the current developer to fix your issues, I've merely kept this project up for archival purposes. I also unfortunately can't tell you which version will run the best as I don't possess an Onn tablet, and my devices are running Android 11, which makes it harder to test. There looks to be a contact form on their website, and I'd suggest going there to see if you'll get a response, especially since they seemed to have removed the issues tracker from...
