I'd love to see someone crack the partial fast update modes of the Boox tablets.

They run Android apps, but only the included, closed-source apps like the note-taking app and browser get fast screen updates at high quality. If you try to install a third-party note-taking app the experience is crap.

Check out what Zubersoft has done with their sheet music app, in a special edition for e-ink.

The kicker is this: “- Freeform annotations with the stylus utilize special rendering on Boox devices allowing the drawings to show up in real time. This makes it much easier to write and draw.”

I use this app on a Boox Max Lumi and the effect is very pronounced. It really doesn’t have any noticeable delay, just like the “native” Boox apps.

So, I think someone did indeed crack the code for fast updating.

Oh damn! Thanks!

Can you not use ADB to download the APK off the app and reverse engineer anything anomalous?

Maybe the apps are completely normal, but whitelisted somewhere in the system for different behaviour. Like some phone manufacturers cheat at benchmarks...

I don't think that's it. The issue is how to tell the screen to do a fast partial refresh at the expense of not refreshing anything else, which is what you want for handwriting. The app would need a way to tell the system what to partially refresh, i.e. some sort of nonstandard Android API.

The Boox tablets are touted for their ability to run third-party Android apps, so I highly doubt they would deliberately cripple them.
