Good Android security update ! ;-)

Not working for Snapdragon version ?

Good work! I tried PE GSI on my S21U Exynos a while ago but it was stuck in 48hz so the experience was not smooth at all and I reverted to One UI stock ROM. 60hz is acceptable.
Which GSI would you say has the best battery life? LineageOS, Pixel Experience or Phh AOSP? Or are they all pretty much the same in this aspect?

are optical zooms used. 100x..

This is by far the most pure experience of android you shall ever see. Unless you use a newer version of AOSP.
I'll give a huge shout out to the makers and maintainers of F-AOSP, for bringing something so quick and bug free!
So without further ado

Bug's
So far I have found, with the help of my brother
1.The video recording doesn't work, as with other versions of custom roms
2.The media volume slider doesn't slide, nor animate when clicking the buttons and playing music. But you can slide the ringer volume.
3.RIL doesn't work yet
You tell me other bugs!
IF SOMEONE CAN HELP ME INSTALL THE RIL I WOULD THANK YOU SO MUCH.

Mod Edit: Quote removed since post removed.
Stop posting the same thing in different threads. THIS IS BASED ON AOSP NOT MIUI so the likelihood is that the camera won't be MIUI.
This ROM is also, as it says in the description, a blend of different ROMS. If the user who has created the ROM feels that it is necessary to put certain applications in their own ROM, moan elsewhere. No one is forcing you to download these ROMS, if you want a STOCK MIUI ROM please download one, or better yet, debloat yourself. It is not hard and you can do it in your own time, do not detract anything from others who are making ROMS for people for free.

Hello,
I have changed the thread from Development to General tag because this thread does not provide kernel source link as request.
If you are sharing other's work, please give the original developer credit by mentioning their IDs, even they are not on XDA.
Thank you.
How use it? Flash or replace stock fastboot firmware? Pls update details. Thanks
That looks cool
What is it..
Size 9GB
No rom
Hi OP,
I think you need to write a guide or something to help others to flash this.
Pls dont flash another bloatware+spyware, there are too many better Open Source ROMs. If you want to flash this, then use MIUI, your stock rom instead.

Question Rom development

When can we expect custom roms and twrp for gt2 ? Bootloader unlock tool has released recently.

Is it? Then please provide the link
Two roms exist:
One based on LinageOS and PixelOS, I can't send link to telegram group here because of XDA rules. But you can find it!

POS
LOS
& Arrow OS
My personal opinion is about custom roms, for now they are good but they have some nasty issues. I tried POS for more than 4 days and now I'm back to RUI with root. Let's see how far this phone goes with custom roms, but for now I'll wait. I don't want to offend the developers, I even thank them for what they do!
