The operating system change to the current /e/ OS ROM e-o.7-o- was done without mistakes. The only thing I noticed is that the link to TWRP on the website /e/ documentation Install /e/ on a Samsung Galaxy A3 (2016 Exynos) - “a3xeltexx”
Installing a custom recovery
- Download a custom recovery - you can download TWRP.
leads to this failure message:

TWRP for Samsung Galaxy A3 2016 (Exynos) Code Name: a3xelte ist verfügbar mit der Version wrp-3.3.0-0-a3xelte vom 2019-04-09 18:10:37 EDT.
But - in the first operation the long known bug appeared → “When I connect to my WLAN at home first time, the phone restarted endlessly, till I shut down wlan on the router.” Read more …
Neither a hardware nor software bug is the missing feature FM Radio RDS, which is known in several Samsung devices of the A-system family.
“The build script for all devices is the same so there is no reason the FM radio should be missing on a particular device.” Read more …
An explanation from @rhunault that I can understand: “Probably a value missing in the device config.”
I hope and wish that the /e/OS Build Team will integrate the FM Radio feature into the build until the relaunch of /e/ OS release v1. My request in this regard will be added to gitlab.e.foundation.

@Manoj’s test build /e/ OS ROM e-0.7-p-2020020439971-test-a3xelte.zip runs smoothly and without the just mentioned “WLAN bootlopp”. The feature anaolges FM Radio with RDS is unfortunately not (yet) integrated.
