I’ve tested Magic earth on e0.1-201811081858 last week and e0.1-201811212056 yestersday
and it’s very impressive !
It works fine on my a5y17lte.
If it could become open-source, (like Openstreet Map is 
) it would be perfect.
Hope /e/ project could helps achieve this !
Thank you to the /e/ and Magic Earth teams for those quality alternatives projects !
