GloDroid v0.7.5

  • Generic Power HAL added. Currently it just boosts all available devfreq/cpufreq on any user interaction. It should make UI more smoother and allow DVFS to be enabled on devices that were previously causing UI lags.

  • Initial AVB (Verified Boot) support. Some steps towards DSU (dynamic system updates) support.

  • Fixed missing sensors HAL on PP and PPP.

  • Fixed UI lags / tearing effects on some systems after migrating to non-blocking atomic commit. (Non-blocking commit support upstreamed).

WARNING: This release wasn't tested. Please use v0.7.4 instead.


  1. Use RRO (Runtime Resource Overlays) instead of legacy overlays
  2. Initial asynchronous DRM atomic commit support (should improve performance on devices with multiple displays)
  3. Replace keymaster HIDL v4.1 with keymint AIDL v1.0
  4. Set animator-duration-scale to 0 for low-end devices. (Disables laggy over-scroll effect and other UI animation)


  1. Kernel & firmware was upgraded to v5.15.33
  2. Ship RPI400 and CM4 dtbs. (RPI400 still have some issues due to missing jack audio)
