Why users turn off Google contacts synchronization

On At first glance, automatic synchronization seems like a harmless function, but it has several significant drawbacks that force users to look for ways to disable it.

If you fundamentally do not want to share this information, it is better to disable synchronization. Secondly, Duplicate contacts is a common problem when the same number is saved several times due to synchronization failures between devices. Finally, many users simply prefer to store contacts locallyin order not to depend on an Internet connection.

• 🔒 Privacy: Google can use contact data to analyze the social graph (who is with whom communicates as often).
• 📱 Duplicates: When synchronizing with multiple accounts (for example, Google + Samsung), contacts can multiply.
• 🌐 Offline access: Local contacts are always at hand, even without the Internet.
• 🔄 Changing a service: When switching to iCloud, Yandex or another synchronization service.

Another good reason - saving battery power. Constantly synchronizing in the background consumes energy, albeit only slightly. On weak devices or during active use, this may be noticeable.
