LineageOS 19.1 (April 2023) for G920F/G925F
You must perform a clean flash. Backup your data using your preferred method, or else you wont be able to unlock your device.
Major changes from last release include:
- Synced with LineageOS source (April 2023 security)
- Reworked the HWC implementation - noticeable improvement to smoothness
- All 7 layers are now working
- More HWC components built from BSP source + extra flags
- Using A810F Gatekeeper blobs - MDFPP implementation from software
- Less random errors in logcat
- Build fingerprints overridden to latest stock nougat ones
- L3 widevine DRM support, some DRM content should work now
- Zswap no longer built in the kernel. We don't need it.
- In kernel low memory killer is no longer built
- Fixed FIPS compilation
- Default voltage offset of -37.5mV on the CPU
- Upped sustained clock speeds hint in powerhints.json
Untested:
- Dual sim support for duo models
- Speaker audio coming from earpiece while headphones plugged in
If you are able to test these issues to see if they have gone away, post in the XDA thread. Sources will be uploaded once I clean it up.
Extra Notes:
I have recreated the stock HWC for our device. We don't need to patch slsi_exynos anymore for our needs. 7 working layers as a bonus. The only component I can't build successfully is libvirtualdisplay, but it isn't a huge deal breaker. We could maybe move to the slsi-linaro sources at a later date, who knows. But as a result of all of the improvements, apps like Twitter, the main android UI and other UI elements should feel better for us.
r22p driver is still exhibiting issues from my testing, so unfortunately we will remain on the r15p driver until I diagnose what the issue is.
