Android 16 QPR1 in Evolution X, FOSDEM release

My first Android 16 QPR1 official release is finally here : introducing Evolution X 11.5.2 !

I touched on the QPR1 situation to explain why this first Quarterly Platform Release took so long to be integrated in custom ROMs - Evolution X not being at fault here - and I am pleased to get it out at long last.

I haven't been sitting idle until now though.

Since my first Android 16 release, 11.4.1, I have been trying to improve the performance of my devices after getting feedback from users about lag and general UI responsiveness.

The situation was serious enough to took it upon myself and search for a solution. Thanks to fellow maintainers and fruitful discussions, I spent some time reading code and sweeping through the changes of a QuinceROMs repository, the developer is providing unofficial Evolution X builds for Snapdragon 855 SoC (SM8150 platform) and OnePlus devices in particular, with a special focus on performance improvements. This is exactly what I needed, having all my Pixel devices based on Snapdragon SoCs while being quite older and less powerful than the SM8150.

By filtering the git history on the changes done in the vendor.prop file in the Android 16 branch, I got a list of commits addressing performance issues.

Then it was "just" a matter of :

  • reading through all those changes,
  • exercising some common sense with regard to my own issues,
  • manually cherry-picking some of those,
  • building and testing them to include or reject.

Simple and straightforward, right ? :-)

I ended up with a few commits providing significant improvements : check them out here.

I also kept rebasing my device tree on the work of LineageOS for Android 16 QPR1, just to make sure I get any upstream fix and improvement that may benefit my users.

Long story short, after a few weeks of patience and multiple testing rounds, we finally have my first official Android 16 QPR1 release : Evolution X 11.5.2 for the Pixel 4a, Pixel 4a 5G and Pixel 5 with decent UI responsiveness !

By the way, I am currently at FOSDEM'26, where I will be presenting on Pixel on life-support, upgrading from Android 12 to Android 16.

More on that topic later.

In the meantime, enjoy Evolution 11.5.2 "FOSDEM 26" release and #KeepEvolving.
