@Vortrex: Probably not, probably DPI settings - if any, and there is none. There was a coder in this thread before that said, that he could modify system level settings such as LED light temperature and that he'd written apps for that - but as of now this form of customizing your device settings beyond the manufacturers consent is beyond our reach.

@xoanohn: Right - and directly following your favorite app of choice - I'll test the other 120 million available on the Play store - for anyone that just asks, really. I think that its a wonderful use of my time. I'll be so happy, when someone buys something, because I said something. Or not. That stuff really makes my day. And if that means, that I'd have to sign up to a few 100.000 web services, I'd do that as well.

Also - you haven't grasped yet, that "screen flashes" are needed for "better contrast" on eInk devices, right? Those are two sides of the same coin.

With most apps - any options likebook implemented to "enchance contrast" (f.e. raise contrast on image content), do nothing. If you use transition animations, this washes out the image, if you use A2 mode, this washes out the image, if you prevent full screen flashes, this results in frequent afterimages - especially with image handling, or browsing (image/text mixed content).

What the Likebook basically does is, that it only refreshes regions of the screen that change, with A2 mode active it tries to redraw, without refreshing - until, after some time, lets say every minute or two - it does a full screen refresh. They/you can prevent it from occuring often - but it comes at a price. You cant get rid of it, its needed for this technology.

There are other people in this forum, who'd like nothing more that to be able to trigger a full screen refresh on every photo/image change on screen. They want that for a reason.

With A2 even the image in Perfect viewer is pretty washed out - and remember I have "contrast enhancement" settings active in that program (native to that specifics programs options). A2 mode in the end is still usable with perferct viewer - but even when it comes to browsing A2 mode has clear setbacks (washes out the image) - watch some youtube videos. Dont make us explain something to you you didnt bother to look up.

Also - even with A2 mode active, navigation and web browsing on this device is slugish at best. NOTHING that you'll do for prolongued amounts of time. Reading Manga in Perfect viewer (with saturation enhancements actiive) in A2 mode, is feasible, but only just. Its not great.
