Extended feature overlay for the Mudita Kompakt
Restore the missing pieces of stock Android — built for the Mudita Kompakt.
KompaktX adds a notification tray, heads-up popups, shortcut remapping, brightness control, eink mode switching, and custom tones.
If KompaktX makes your Mudita Kompakt more usable as a daily driver, consider supporting development:
The Mudita Kompakt is a minimalist eink Android phone, but it ships without a notification shade, heads-up notifications, and several features many Android users expect.
KompaktX fills in those gaps with an overlay layer designed specifically for the Kompakt.
KompaktX adds a practical, eink-friendly feature layer on top of the stock Mudita Kompakt experience.
