If you only want to disable background synchronization for emails (and not for messenger apps or whatever) then I guess system settings are the wrong place.
I would simply disable synchronization in k9. Either globally or per account. Depends on what you want to achieve
From Android, native from Google or costum from LineageOS, I know at least to ways to disable synchronization in a global manner.
Widget for desktop with a cycle symbol (older Android versions).
Cycle symbol, when I pull down the notification bar twice (newer Android versions).
Both ways are missing in FP os (or i am unable to find them) and I really really miss them. To be able to disable/enable synchronization in a global manner is more the comfortable. Is there no such thing in FP OS with similar function?
That is exactly how I proceeded on my Galaxy S3 with the latest LineageOS. It worked out well. Since that day I am a huge fan of the sync icon to enable/disable synchronization in an overall manner.
Since last week I am FP2 user und did I mention: “I really rellay miss that feature”.
Thank you very much anyway.
I am thinking about switching to Fairphone Open. Does anyone know, whether overall synchronization is solved in the Android/CyanogenMod/Lineage manner there?
Dear Ingo,
thank you for the hint. On the first glance I do not get how the Custom Quick Settings application works. When I have a lot of free time, maybe in vacation, I will try it again.
