- Device Specific Changes Etude kernel: Op.13 No.2 Linux 4.9.337. The 4.9 kernel reached EOL from upstream stable kernel release. built with the latest LLVM Clang 16 backported configurable per-cgroup PSI tracking guarded a deprecated clang-specific auto zero variable initialization flag a few fixes for compressed apex and encryption picked a few fixes for qcacld and sdcardfs changed f2fs defaults to match the default tuning values in AOSP aligned Clang ThinLTO flags with mainline kernel to take advantage of thinlto-cache link vdso32 with -z noexecstack to avoid warnings in bfd from the latest GNU binutils DO NOT use another kernel. Just don’t. Disabled per-cgroup PSI accounting to avoid performance overhead because android does not need it Enabled compressed apex Fixed carrier video calling by adding the missing [email protected] library Significantly simplified the system-side IMS blobs Overrode Pixel thermal HAL service initialization to fix boot issues after android 13 QPR1 merge - ROM Side Changes January security patch GApps updated from QPR1 and later builds We did several changes to try fixing the screen stutter and battery drain caused by Pixel Launcher. If the issue persists for you, try uninstalling previous updates of Android System Intelligence or even do a clean flash. Disabling search related features in launcher settings may also help. - PE recovery is REQUIRED DO NOT use any other recovery Partition scheme has been switched to retrofit dynamic partitioning because polaris is running out of system partition space. No actual re-partition is involved. Instead, the physical system and vendor partition is mapped together to form a logical “super” partition. The size of super partition equals the sum of the physical system and vendor partitions. After that, logical system and vendor partitions are created on top of this super partition. In this way, we are essentially redistributing space between the physical system and vendor partition to accommodate for the increase in size of system libraries and prebuilt apps. The firmware is included with a different keymaster.img from perseus. DO NOT flash your own firmware. To switch to other ROMs, format data in PE recovery first, and then install another recovery. You may need to re-flash the required firmware, if the ROM you are going to flash does not include one. You can dirty flash from the previous PE 13 builds. You can dirty flash PE 13 Plus on top of the regular PE 13. You cannot upgrade from android 12 builds. Formatting data is required.

- Initial PE 13 stable release. - Device Specific Changes Etude kernel: Op.13 No.2 Linux 4.9.333 built with the latest LLVM Clang 15.0.2 and full LLVM binutils, including the LLVM integrated assembler added time slice duty cycle in wifi_interface_info to address the log spam in android 13’s WiFi HAL added a backport of EROFS from 5.10. Currently nothing is using this filesystem, but we might use it in the future. updated to the latest mainline exFAT driver fixed a mismatched bound in qcacld backported and enabled DWARF5 debug symbol for the kernel build fixed crypto assembly for LLVM IAS DO NOT use another kernel. Just don’t. Enabled zygote critical window More fixes for the new AOSP BT stack Some updates to the USB props and default USB device name Disabled advance network scan because our device is a legacy target Enabled and configured main and telephoto cameras for the Aperture app - ROM Side Changes November security patch Face Unlock is back Translation updates The Plus edition is back. Perhaps not all customization options are here yet. They will be added in future releases. - Known Issues Qualcomm’s WiFi Display (WFD) works fine. However, if you have a saved WFD connection, you may see the screen cast logo appear in statusbar after a reboot. Just press disconnect from the screen cast QS tile if that happens. If you enable bubble for the built-in Message app, the translucent background may flicker when the bubble is activated. Carrier video call may be broken for some carriers. Please disable this feature on your SIM card settings page if your carrier is affected. - PE recovery is REQUIRED DO NOT use any other recovery Partition scheme has been switched to retrofit dynamic partitioning because polaris is running out of system partition space.

This is a maintenance build with November security patch. This build includes a fix for a recently revealed security vulnerability in AOSP's keyguard. PE 12 is deprecated, and there will be no more PE 12 builds in the future.
