In this thread I'll share with you my personal builds of LineageOS 21, 20, 19.1 and 18.1 for the Essential PH-1 (codename: mata). These builds are unofficial LineageOS builds, customized with my favorite tweaks and features, and with some interesting optimizations.

KERNEL FEATURES
Starting from build 2023-10-25, a new kernel is included in my builds. This is based on the latest CAF tag for the Snapdragon 835, with a few additional improvements, mainly for Energy Aware Scheduling. This means that all the tweaks and improvements I had previously made to my kernel are now gone, and I have to reimplement them from scratch, which I'll be doing over the next few weeks. At the moment, only these additional goodies are implemented:
- lots of bug and security fixes backported by the Civil Infrastructure Project
- memory management improvements
- lots of debugging bloat removed from several drivers
- DDR bandwidth boost when launching apps and in other scenarios
- built with -O3 optimizations
- many small, miscellaneous patches to improve performance and power consumption
- updates for zram/zsmalloc (and for the LZ4 compression backend too)
- power-efficient workqueues are implemented in many drivers
- simple_lmk by kerneltoast replaces standard LMK
- Kcal & Klapse
- maple I/O scheduler as default
- DDR bandwidth boost when launching apps and in other scenarios
- DriveDroid support (not tested)
- Wireguard support (not tested)
- lots of patches to improve memory allocation-related overhead
- hardening against buffer overflows (thanks to the GrapheneOS team)
- USB controller driver updated (MTP speed improvements)
- memory routines optimized for the arm64 architecture
- built with -O3 optimizations
- binder driver backported from Linux 5.4
- lots of drivers and components only useful for debugging are disabled
- many small, miscellaneous patches to improve performance and power consumption
BUGS
Common to official/Nolen's builds as well:
NFC quirks (payments with Google Wallet are working, other usecases might or might not)- fixed in the 2023-03-11 buildUpdater shows wrong percentage during OTA package installation- fixed in the 2023-04-11 build- microphone issues in some scenarios - WIP
- Klik misbehaves when rotating the phone while viewing a previously taken picture (low severity bug)
; Klik sometimes quits when switching to front cam or B&W mode (high severity bug) - under investigation, read more about Klik's status here - updated 2023-04-12 some games do not load- fixed in the 2024-02-27 build and in subsequent official builds[LineageOS 21 only] an exclamation mark is persistently shown on the mobile network signal icon - under investigation: this is just a visual bug, mobile data/VoLTE work fine!- it disappears after the first reboot
Specific of my builds:
the fullscreen dark background in the notification pull-down view is now transparent - notifications are displayed directly on top of the currently active application. This doesn't affect functionality but is indeed unpleasant to the eyefixed in the 2023-03-21 build- SIM hotswapping does not work. Only insert a SIM when the phone is powered off, or reboot it after insertion.
