Android S4 my "Calendar" under "Sync settings" in my Google account disappeared. Under the Google accounts at the bottom it reads "Sync is currently experiencing problems. It will be back shortly" How do I fix?
We had the same problem, and to make a long story short, tried all the answers we found online (clear cache, clear data, reinstall Calendar, delete, then create Google account, but no factory reset).
The problem for this phone (Samsung Galaxy S3) was that we had restricted background data on Google Play Services. Once that was enabled, the calendar synced right away.
Home> Settings> Connections> Data Usage> Scroll down to Google Play Services, and make sure to uncheck "restrict background data".
Not closely related to the issue, but it solved my very similar problem with contacts sync:
Contact option was not listed in Android's (v.6.0.1, Marshmallow) Settings / Accounts / Google sync menu.
The problem was that the Contacts Sync application had no access right to my contacts.
To fix this, I switched the Settings / Apps / Gear icon / App permissions / Contacts / Google Contacts Sync toggle.
After that it started to sync, but I got the same 'Sync is currently experiencing problems'.
It turned out that I exceeded the Google API call limit for the day, so after 24 hours it synced successfully.
To figure out what the problem exactly was I connected my phone through USB to my PC, enabled debugging on the phone, used the
adb logcat command from the Android SDK and examined the errors/exceptions in that log. This way you can get to the bottom of your calendar issue as well.
To sum up my fix. Checked my on-line google calendar settings to ensure mobile syncing was active. It was. On my Samsung S4 I uninstalled google calendar & re-installed a couple of times. Still kept receiving the syncing message. So I removed my google account & reconnected. That's when I received the message "The process android.process.acore has stopped". Based on users comments the best fix would be to reset to factory. Which I did and all is good except for losing SMS history
In my case, the error was with my Samsung account on my GS4. When I pressed 'Profile' underneath the sync option, it prompted me to install an update which may have been the cause. When I pressed 'Yes' it failed to update. However, once I restarted the phone the update successfully installed.
For anyone with this problem, I would advise restarting your phone, then (for Samsung accounts), go to Settings > Accounts > Samsung account > Profile
Install the update if prompted. Lastly make sure Sync is enabled in the notifications bar.
I have just had the same problem after an android upgrade on my sony xperia Z5. And luckily fixed it. I had to delete the account and then re-add it. I think I know why this worked as I have seen a similar problem before (with dropbox about 2 upgrades ago): with this new android version a new security feature was added and exchange couldn't automatically access my calendar/contacts -> it wasn't allowed. When you re-add the account you are asked if exchange is allowed to access contacts and calendar. Once you say "yes" all works. I really think android needs to handle the addition of new security features to existing apps in a more elegant manner.
I had the same problems and finally was able to fix it.
I always try to use my phone on power saving mode to save battery, after the last update I had some troubles with that feature because many apps don't work properly. Well, all I had to do was disable power mode and sync again and voila, everything sync perfectly.
I hope this helps.
If your device is rooted then delete the folder under
/data/data/com.android.providers.calendar and reboot. (I used Total Commander.)
For problems with contacts sync the folder is
In brought back the sync on my device which has been constantly "experiencing problems" for about half a year.
