I have a problem still I intalled the lastest version of open OS (16.10.0).
I had the play store installed on my fairphone, but it is disapeard. I can’t reinstall it. I followed steps from this : ✏ Install OpenGAPPS (Step-by-step guide).
On the lastest version of open OS it was ok, but now, when I start my phone on TWRP mode to reinstall the play store, I can’t find the downloads, so it is impossible to install it.
