I need a FOSS contact apps and only condition is, it should integrate with my system contacts so that I can use it with my dialer,messenger,etc. (Tried Connect you but too buggy)
It is not saving them to local contact storage.
It works fine for me, perhaps you didn’t grant the app Contacts permissions?
I tried saving to “Device”. That seems to work.
I second that. Fossify also has a whole suite of other apps. It’s a fork from Simple Tools which sold out. Fossify Gallery is awesome and also available on Play Store. Other apps are making their way there. NB! Not connected to Fossify, just a fan of what they’re doing.
I use Connect You (FDroid) which also creates a local backup that I use with SyncThing to create a backup on several other devices.
Losing your contacts suuuuuucks and I only did it once.
Never experienced any bugs
