Small tangential question, but I thought better ask it here than just waste a whole new topic - would the following app work with Fairphone OS? And/or possibly with Jolla?
Edit by @Stefan: This post and the following 2 were moved here from another topic.
@Ed_Bycroft: I’ve tried Airdroid on my FP1 and yes, it works. But I find it easier to shuffle files between phone and PC using a USB cable.
An alternative for FTP transfer over a shared wlan is to use ES File Explorer (on your FP) and a FTP client (e.g. filezilla) on your pc.
Ah, many thanks! I’ve only been curious about it for the connectivity re: remotely controlling the phone, picking up specific notifications etc. Your help is much appreciated.
With MyPhoneExplorer you can browse files, send texts, sync address books and much more. Using it for years now and I’m totally satisfied with it. 
Very similar in functionality is Pushbullet. I’ve never tried it though.
When I was using Airdroid (some years ago), I was not satisfied (for reasons which I don’t remember anymore). It might have changed a lot since then of course.
Huh, that actually looks pretty good! Especially considering its cross-platform applications. My thanks, stranger!
