Features

ProtonAOSP offers many improvements on the stock Android experience:

  • Better performance
  • Clean UI design
  • Improved memory management
  • Under-the-hood tweaks
  • Privacy
  • Convenience
  • Default experience

It also keeps what you’re used to on stock:

  • SafetyNet passing out-of-the-box without root
  • Some Pixel-exclusive features

Better performance#

ProtonAOSP is more smooth (i.e. less jank) and responds faster than stock. The performance improvements can be attributed to:

  • Vulkan UI rendering
  • Reduced APEX overhead
  • Deep, low-level system optimizations throughout the system

The performance improvements have been empirically proven on a Pixel 5:

  • Up to 18% faster app/menu/screen opening
  • 16% faster screenshot capturing
  • Up to 4x faster low-level memory management
  • Faster image loading and saving (JPEG and PNG)

See Performance for technical details.

Clean UI design#

We pay attention to details in the user interface:

  • Easy-to-read typography with Inter, Source Serif Pro, and Fira Code
  • Light and dark colors derived from the Primer Design System and modified in a perceptual color space
  • Frosted glass blur with state-of-the-art rendering techniques
  • Fewer distractions in the system
  • Builtin wallpapers designed by Infinitum

See Theme and Blur for technical details.

Improved memory management#

You can keep more apps in memory, thanks to several memory management tweaks:

  • Optimized memory pinning
  • ART heap compaction
  • Higher background app limit (helps devices with 8+ GB of RAM)

Under-the-hood tweaks#

We’ve fixed some minor bugs from Google’s stock OS:

  • Better 5 GHz Wi-Fi signal retention
  • High-resolution recents overview
  • Fixes for some AOSP bugs
  • Latest Chromium WebView

Privacy#

ProtonAOSP is not dedicated to improving privacy or security, but it still has some features to help keep your data private:

  • Support for microG
  • Secure quick settings
  • Internet & sensor permissions
  • Camera and microphone usage indicators
  • Permission usage dashboard
  • Minor hardening from GrapheneOS

Convenience#

We also have a few assorted features for your convenience:

  • Clear battery usage stats on demand
  • Call recording (where legal with one-party consent)
  • AI-powered back gesture
  • Adaptive brightness toggle in quick settings
  • Memory usage in Settings
  • Advanced settings expanded by default
  • Command-line tools for developers

Default experience#

The out-of-the-box experience is made to fit your needs:

  • Modern default settings
  • Material ringtone, alarm, and notification sounds
  • 2D and photo wallpapers

SafetyNet#

Unlike many custom ROMs, ProtonAOSP passes Google’s SafetyNet attestation checks out-of-the-box, so you don’t need to do anything. However, don’t take it for granted — Google could break it at any time. Unofficial operating systems rely on a variety of workarounds in order to pass SafetyNet, so it should not be expected to work forever.

See Passing SafetyNet for more information, and SafetyNet for technical details.

Easy-to-use guided web installer#

ProtonAOSP is easier to install than most other custom ROMs. It has an easy-to-use guided web installer, so installation is just a few clicks and takes as little as 4 minutes (depending on the speed of your internet connection). You don’t need to worry about using command-line interfaces, downloading tools, or bricking your device.

Pixel-exclusive features#

Not all Pixel-exclusive features are included due to their proprietary nature, but some of them are available:

  • Live Caption
  • Now Playing
  • Screen attention (Pixel 4+)
  • Adaptive 5G connectivity (Pixel 5+)
  • Adaptive Sound (Pixel 5)
