Excellent @anon26953564, you’ve learned quickly to build a GSI eOS ROM that works right out of the box. Thank you for taking the time to do this.
I installed your latest eOS ROM on my treblesized Galaxy A3 2017 ‘a3y17lte’ via TWRP 3.4.0-0, previously running @harvery’s eOS-Q-Full-_arm64_bvS-20201017 ROM, and was only able to briefly test three key features.
On first start-up, the SIM card is immediately recognised and the PIN is requested. Incoming and outgoing calls and text messages work as well as surfing via WLAN.
I am curious to see whether and which COVID-19 Warn app will work.
