The device is less common…
I had bought one by error 2 years ago, but have solded it to a friend with LineageOS because the lack of /e/OS build.
I will rebuy it because she don’t use it.
Right, the i9506 also run’s fine with LOS 20 (T) which performs very well and nearly bugless I tested…

It exists also a LOS 21 build, but the videorecording fails and there are also some more bugs unfortunately…
