Huawei MatePad Paper Refresh Mode Switcher (mp2.0)

Long-press the floating button to open a popup that picks the e-ink EPD waveform mode and applies it on the spot, so you can see the difference between waveforms on the Huawei MatePad Paper.

Modes (fastest → clearest)

Mode	Hint
6 ANIM / A2	fastest, most ghost
1 DU	fast, black & white
7 DU4	balanced, 4 greys
5 GLD16 / DU4	balanced grey
4 GLR16	anti-ghost grey
3 GL16 / REAGL	clear grey, anti-ghost
2 GC16	clearest, full 16 greys
0 INIT	full clear / reset
13 MOD32	partial / special
15 AUTO	driver picks

Plus a Clear ghosting action (GC16 full pass).

How it works

On selection it applies the mode three ways by reflection and toasts which the device accepted:
EPDCDevice.setEpdcDefaultMode(int), EPDCDevice.forceRefresh(int), View.setPostMode(int).
A2 ≈ mode 6 (EINK_REFRESH_MODE_A2_1BP = 0x2006 = 1BPP | ANIM): fast but ghosts while scrolling, settles clean on stop.

Install (sideload)

adb install -r AssistiveTouch-matepad-paper-eink-waveform-mp2.0.apk
# optional: flip the global Normal/Smart strategy
adb shell pm grant com.android.mirror.assisttouch android.permission.WRITE_SECURE_SETTINGS

Enable the accessibility service and allow "display over other apps", then long-press the floating button.

Notes

• Tested on MatePad Paper (HMW-W09, Android 10)
• Debug-signed build for sideloading; device/ROM-specific, not for store distribution.
• Gestures: single-tap = Back, double-tap = Home, long-press = refresh mode picker.

Supernote 快刷模式 / fast-refresh v1.0

AssistiveTouch tuned for the Supernote (Nomad / RK3566 e-ink).

A draggable floating button with these gestures:

• Single tap — Back
• Double tap — Home (system default launcher)
• Long press — toggle SPEED (A2) fast-refresh mode

Fast-refresh toggle

Long-press flips the whole e-ink panel into the fastest refresh the system exposes:
EinkManager.setScreenMode(SPEED) plus disabling Regal (the anti-ghost waveform pass). Long-press again restores normal quality and does a full clear to wipe ghosting. It does not alter the device's auto-GC settings — fast mode stays pure and you refresh when you want.

Built from the supernote branch. APK is debug-key signed for sideloading; if upgrading from an official release-signed build, uninstall first.
