@harvey186, first of all thank you for your work & time.
Your minimal eOS pie version for the Samsung Galaxy S4 - GT-I9505 “jfltexx” shows that a migration to /e/ OS 9-pie is possible. Especially with more time and some dedication in detail, the one or other hurdle can be mastered for sure. This is proven by very well working LOS 16.0 & 17.1 ROMs from developers I know.
The strongly app reduced “mini” /e/ROM (~ 415 MB) with its eight system apps also offers the chance to design a /e/ phone according to your own wishes. I also liked the fact that I don’t need to uninstall the weather app. I replaced the Che-Peace-Hippy animation with the e-boot animation. I like the original //r logo.
.
The e-0.9-p-20200601-mini-jfltexx also comes without microG components and is not microG ready according to the Signature Spoofing Checker. However, this 9-pie build can be made microG ready with the NanoDroid-patcher according to Signature Spoofing Checker. So nothing stands in the way of the installation of microG.
If you install microG with the NanoDroid-package you have the advantage that microG can be removed completely with the NanoDroid-uninstaller. All zip-files can be easily copied to the “jfltexx” via TWRP > Install.
The mini /e/ROM requires two essential app installations: Phone Dialer and SMS Messenger. Since I’m a fan of SimpleMobilTools anyway, I added these two apps and also the other apps from the same developer via the pre-installed F-Droid Store.
To add some more /e/ feeling, I installed the foundation /e/ apps, browser and camera.
.
The “mini” /e/ROM e-0.9-p- has potential and should be further developed and maintained, not only to stand up to the LineageOS Project with its LOS 17.1 ROM, but to show what /e/ can do.
