BOOX Palma 2 · Customization
Optimise a single app on the BOOX Palma 2
The Palma 2's per-app optimisation dialog sets refresh mode, contrast, DPI and animation handling. On a 6.13-inch screen, DPI is the one you will change most.
Every Android app on the Palma 2 gets its own optimisation dialog — refresh mode, contrast, DPI and animation handling. On this small a screen, DPI is the setting that fixes the most: nudge it down to make a cramped phone app readable, up to reclaim wasted space, and test after each change.
Before you begin
-
Open the optimisation dialog
Swipe down the status bar and tap the app-optimisation icon while the app is open, or find the app in the BOOX app drawer, long-press it, and choose "Optimise". A panel of sliders and toggles appears.
-
Set the refresh mode
HD or Regal for reading apps. Balanced for apps with light scrolling. Fast or Ultrafast only for video-like content — text ghosts badly in those.
-
Adjust DPI to fit the small screen
This is the key one on the Palma 2. Many apps assume a phone and pack in too much. Lower the DPI a notch or two to make buttons and text bigger; raise it if an app wastes space. Change it in small steps and reopen the app to check.
-
Tune contrast and "bleach"
Use "enhance contrast" or "bleach" to darken faint grey text and clear a dingy background. Push it just far enough — too much crushes thin strokes.
-
Handle animations
Turn on "filter animations" or "flatten" for apps that fade and slide. Fewer animations means fewer half-drawn frames on e-ink.
-
Save and test
Close the dialog, fully reopen the app, and use it for a minute. Re-open the dialog to fine-tune. Settings are remembered per app.
