TL;DR; Is there a working FOSS alternative to the system dialer on FP3? Which Dialer did OpenFP2 OS use? Is it available anywhere?
I noticed - after installing NetGuard, that a lot of the preinstalled system apps on FP3 phone home to big brother google, even those you would not expect to.
I successfully replaced Contacts, SMS/Messenger, Calendar, The Launcher, Keyboard, Gallery and Music player with FOSS variants from F-DROID.
This leaves the system Dialer app, responsible for making outgoing and receiving incoming phone calls. According to NetGuard this app tries to connect to various obscure domain names
fra15s12-in-x0a.1e100.net, fra16s20.in,f10.1e100.net, …)
both domain and resolving IPv4 and IPv6 addresses belong to GOOGLE INC
Naturally I don’t want the system dialer to call home, especially when its in the background and I’m not even WANT to make any calls.
I tried installing the Open Source Emerald Dialer, and replace the default. But with that its not possible to receive any calls. (The phone rings, but there’s no UI element to take the call. It IS possible to make outgoing calls, but only when the screen is rotated landscape, in portrait mode the app crashes)
I couldn’t find any other FOSS dialer apps, is there anything out there that works on FP3?
