Say, by sending some value to something inside /sys/.../cpu or the likes. I have already aggressively debloated the tablet, but I like to experiment and I am not afraid to destroy the tablet since I bought it for 150 bucks at sale. Or pehaps there is some Magisk module that can do this?
The tablet is a Samsung Galaxy A9+.
Yeah, most just run a Android with reader-centric launcher and some of the Kobo devices have even LineageOS support. But like stated; they are barely powerful enough to run the launcher fluidly. And battery life sucks for a E-reader. Honestly, nowadays i would go with a Tablet and/or a PocketBook; they at least run a optimized Linux.
About my setup: all animations disabled in developer options, launcher inkOS, apps like Kotatau, Myne, Librery and Book Reader from F-Droid Classic. And Cromite with the setting to display a context menu on link, for those old.reddit stories.
I’ve gone with “Performancr Tweaker” from apkmirror now, this helps a bit, have Magisk anyway.
Cool! I had little to now knowledge on e-readers… Wanting to buy one, and realizing how expensive they are, is what made me go for the Galaxy Tab A9+. It was about 150 bucks, on sale. I don’t regret it.
I hope tweaking the scaling governor helps you some, but as I have stated in the various updates in the OP, it has its quirks…
