[HowTO] Treble for S9

[Paradoxxx]

Hello everyone,

After seeing the news that Treble images were properly working on the S9, I decided to give it a go and see for myself how good/bad was it working.

The from my findings, the only thing that is NOT working is the auto-brightness.

Here are the installation steps :

Make sure you got TWRP installed properly, with DM-Verity and Encryption disabled.

Download this : https://www.androidfilehost.com/?fid=817906626617958348

Place it in the root of your device, then navigate to TWRP, click install, click install Image, select the transfered system.img, and select system image.

Make sure to full wipe after that, and reboot, and you are good to go.

This is awesome. As soon as I'm able to get my hands on an Exynos variant S9, I'm buying one for Treble support alone.

Auto-brightness doesn't work because the framework doesn't define any brightness levels for each lux level. You can make an overlay to fix that or modify the framework at source.

I'll pass onto phh, see if he can include a fix in his builds.

Any idea how to build a treble image?
I know how to build for a specific device but treble... bohh. Maybe you can help me.

phh is sharing his build script : https://github.com/phhusson/treble_experimentations/blob/master/build.sh

That should get you started

It's also framework related so very much unlikely to happen.

 

[YaoSta]

have you guys also tested if the telephoto lens activates when you zoom in?

It's also framework related so very much unlikely to happen.

Porting the frameworks has recently happened for Huawei and Sony. Unless Samsung are deliberately obfuscating things, it should be possible to do the same for the Exynos versions of the S9 and S9+.

 

[Bangbang_cannon]

Can someone post screenshots

 

[Griffiths_Anna]

Im so excited .. this is one of the biggest reasons why I will switch to s9+

Yes

 

[pavneet10174]

Yes

Hey thanks a lot for helping,

I have one more question, when I flashed aosp ROM it worked fine but with the brightness glitch, however when I flashed lineage os it just bootlooped so any suggestions ?

Thanks

26th builds of 8.1 are okay for brightness but fingerprint is broken for some and causes touch to stop but reboot, unlock then a few lock/unlock cycles it's good temp fix til next reboot
