Problems with sync
On most Android devices, the Calendar app is automatically synced with the Google Calendar server, and vice versa. If you experience problems with sync, these troubleshooting steps may help:
Check your network connection
The Calendar app needs an active data connection (mobile network or Wi-Fi) to sustain auto-sync.
- Make sure your device is not in Airplane mode.
- Make sure your device has a working signal.
- Verify that your device can get online (try going to a website in Browser).
Make sure Auto-sync is enabled
- Press your device's < Home > button, then press < Menu >.
- Select Settings.
- Select Accounts & sync.
- Make sure the checkbox for Auto-sync is checked.
Turn sync off and on
- Press your device's < Home > button, then press < Menu >.
- Select Settings.
- Select Accounts & sync.
- Select the account with sync problems.
- Uncheck the box next to Sync Calendar to disable Calendar sync. Then check the box to re-enable Calendar sync.
Note: If the box next to Sync Calendar was unchecked, simply check the box to re-enable Calendar sync.
After completing these steps, wait for auto-sync to resume (this may take several minutes).
