Released on September 20, 2020.

This is the initial version of ProtonAOSP that started the project, before it had an official name. It was a small collection of improvements on Android 11 back when it was first released.


  • Better performance than stock
  • Enhanced typography (harmonious font selection)
  • iOS blue accent color & dark theme colors
  • New open-source Active Edge implementation written from scratch (currently force-enabled at medium sensitivity to take a screenshot on squeeze; settings will be added soon)
  • UI tweaks from the Pixel stock ROM
  • 3-row quick settings when no media is playing
  • Glass blur in the notification shade and recents overview (with performance & quality tweaks)
  • Up to 40x faster shared internal storage (emulated SD card) than stock Android 11, same as Android 10
  • Instant screenshots with key combination
  • Improved UI performance using Vulkan rendering backend
  • Signature spoofing support for microG
  • Internet & sensor permission controls from GrapheneOS
  • Minor security hardening from GrapheneOS (nothing that hurts performance much)
  • Screenshot preview dismisses faster and is cleared before taking a new screenshot
