PixelExperience 11.0 20210417-0245 Official Polaris Build

Etude update, 1286MHz frequency lock fix, new thermal configs, new dynamic thermal profiles, sepolicy rework, telephony and secure element blob update, switch to suspend to RAM from s2idle, April security patch, weather widget fix, and improved Face Unlock!

Device Specific Changes:

  • Etude kernel: Op.11 No.4
    • Linux 4.9.267
    • some upstream fixes of cpufreq_stats
    • fixed an issue where the frequency of big CPU cores is locked to a maximum of 1286MHz; the frequency of the big cluster is supposed to be restricted under 1286MHz if you battery is at or below 10%, as part of Qualcomm’s thermal mitigation, but on previous versions, the frequency restriction was not removed after the phone is charged above 10%
    • default to suspend to RAM instead of s2idle (suspend to idle) for around a 25% reduction of idle battery drain
    • DO NOT use a third party kernel without proper support for Pixel thermal hal
  • Adjusted thermal configs to delay CPU frequency drop and smoothen the thermal throttling curve
  • Implemented dynamic thermal profile to work with Pixel thermal engine
    • the option is accessible under Settings/Battery/Optimization profiles (in case you are wondering, they had no effect on PE11 before this change)
    • thermal configs are dynamically loaded on a per-app basis
    • only the gaming profile is available besides the default profile, because other use cases are covered well enough by the default profile
    • the gaming profile maintains CPU frequency at even higher temperature compared the default profile
    • surface temperatures are measured by an infrared thermometer with matching emissivity to ensure they stay below the allowed maximum values of continuously held electronic devices in IEC 60950-1 (2005) standard
    • thermal profile is NOT a replacement for proper cooling. If you want better performance, you should cool your device.
  • Eliminated all SELinux neverallows and cleaned up unneeded or broken sepolicy
    • the latest Riru installation should work now. Note that if you use any mods like this, you will not receive support from me
  • Updated telephony blobs from pyxis 21.3.31 to fix random qtibus crashes in the background
  • Went back to Secure Element 1.0 to work with the updated blobs
  • Stopped enforcing s2idle from userspace init script so the kernel can suspend to RAM for better idle battery drain
  • Cleaned some unused config overlays

Feature Update Highlights:

  • April security update
  • Fixed the issue of weather information not showing up in “At a glance” on the home screen of Pixel Launcher
  • Improved Face Unlock. The issue of front camera being occupied should happen less frequently. Let me know if you still encounter it
  • Devices will only use dark boot animation from now on
  • Translation updates

Gapps are included. Vendor and firmware are included. OTA or dirty flash is fine if you are on my previous PE 11 build.
