Calendars disappear on a Galaxy S7 (Android 6.0.1)



  • Hi

    I used to sync my calendars and contacts from my Owncloud (8.2.5.) on my S4 and everything worked fine.
    Now, on my new S7, I am facing a very weird behavior on the calendar app (primarily S Planner, but I also installed Google agenda for double check) : after some time all my caldav calendars disappear. The automatic and manual sync works fine. After a vanishment of all my calendars, a manual sync make them re-appear again… for some time…

    My info :

    DAVdroid version: 1.0.9.1 (101) Fri May 27 07:58:12 GMT+02:00 2016
    Android version: 6.0.1 (MMB29K.G930FXXU1APD1)
    Device: Samsung SM-G930F (herolte)
    
    I did activate your log and got things like that sometimes

    The time before vanishment is unpredictable but I have the strong feeling that this problem happen much more often with unstable network (from wifi to cellular back and forth) even if it doesn't necessarily correspond to a schedule automatic sync.

    Is that ring a bell for you ?

    Hello,

    Unfortunately, I don't have any idea what the reason for this behaviour may be. Your posted log messages don't indicate any problem.

    To be able to help you, we would need to reproduce the problem. On an S6, everything works (we have one for daily use here).



  • Hi,

    hope it's ok to add to this thread, although in my case a different CalDAV sync-app was involved. However, I experienced the same problem with disappearing calendars (both CalDAV and e.g. Google) on a S7 running a stock 6.0.1 Android.

    As it seems so far, the component causing the problem was the system app "Calendar storage", which was up and running but lacked the permission to access contacts (even though calendar and storage permissions were enabled). About this app, see also this google answer under "Next, try these ..." - Android. Clearing the app's data as suggested was not necessary in my case.

    HTH.



  • Bingo !
    Yes indeed that solved my problem. Thanks
