treble_experimentations VS TraditionalT9

Unlock and install LineageOS or one of other alternatives.

Good resource: https://github.com/phhusson/treble_experimentations/wiki

If you go to the GSI Github used in the video, the newest version available is 12.1, and this has not been yet built for a ARM-AONLY build, which is what Dylan suggested. I used the most recent ARM-AONLY build. If someone wants to try building ARM-AONLY for the newest release of GSI Android 12.1, I would love to hear their results. If someone wants to try flashing a different build like ARM64, I would be interested to hear the results of that as well.

Android 12 requires Linux 4.4 for proper networking and cgroup handling, which the Pixel 1 doesn't support. Skipping those requirements isn't a good idea.

p.s. status on this? thanks https://github.com/phhusson/treble_experimentations/issues/1...

Front screen doesn't work with GSI. After installing the Qualcomm IMS apk in the GSI's settings, it shows me a T-mo logo.

You can put a full GSI rom on the Cat S22 like I did! see

There is a reason, why phhusson is putting a lot of work into building their own GSIs even though Google releases official GSI builds. And yet, the list of issues is still long because minor things are broken on different devices.

I want to upgrade my Jelly2 to GSI 12.1. I'm okay with a potential soft-brick. Indeed, I just got this phone and haven't done anything with it yet, so if I have to re-flash it I'm fine with that.

FYI the CAT S22 works now with the Android GSI https://github.com/phhusson/treble_experimentations/issues/2295

Or install Android AOSP from here

Not convenient to type on (again duh), you lose the T9 on the GSI so I actually compiled TraditionalT9 myself for T9. I am about 50/50 using that vs using the tiny on-screen keyboard.

I'm using Traditional T9 - here's a good thread that I picked it up from on this reddit. It's available on the Play Store (or via your favourite APK-obtaining mechanism), but I think I actually used a slightly hacked version that was linked in that thread. If you're interested, that was the one made by Henri Dellal (forked from the original code here). Annoyingly, that hacked source has been moved and the links in the old thread don't word - but I found where it had been moved to! The source is here https://codeberg.org/HenriDellal/TraditionalT9, and you can get the built APK off the old github site using the Wayback machine: https://web.archive.org/web/20200919201626/https://github.com/HenriDellal/TraditionalT9/releases/download/20190315/t9.apk

Not by default but it can be added: https://github.com/Clam-/TraditionalT9/wiki/New-Language-support

This experience matches mine. Never had problems group texting. Also find the predictive text a little frustrating (it's also seemingly impossible to reliably type contractions like "I'm"), but not deal-breaking. I see in another comment here that there's an open source T9 Android keyboard [1] that I may try out...
