Turn Automatic Data Sync On or Off auf Realme
Automatic data synchronisation keeps information linked to your Google or Realme account current in the background. Contacts, calendar entries, app data and, depending on the account, photos update without any manual action on your part. When the option is switched off, changes made on other devices or in the cloud stop reaching your phone until you sync it yourself.
Realme UI on Android manages this setting per account from a central accounts screen, not inside each individual app. Turning it off can reduce battery drain and mobile data use, but contacts or calendar changes made elsewhere will not appear on this phone automatically anymore.
How to change the setting
Open Tap on Settings ➔ Tap on Users & accounts ➔ Enable or disable Automatically synchronize personal account data ➔ Tap on OK to confirm your choice.
If only certain data types should stay unsynced, check the account itself, for example Google, for separate toggles for contacts, calendar or photos, instead of turning off sync for the whole account.
