Messenger Telegram automatically synchronizes phone contacts, filling the list of chats with numbers that are no longer relevant. On smartphones Samsung Galaxy (series A54, S23, Z Flip5 and others), this function works especially aggressively - the messenger can even add random numbers from the history of calls or SMS. As a result, the contact list swells to hundreds of entries, among which it is difficult to find the right people.

The problem is complicated by the fact that Telegram does not provide a direct function for bulk deleting contacts each number has to be cleaned manually. In addition, after synchronization with the phone book Android contacts may be duplicated or displayed with incorrect names. In this article we will analyze 5 working ways to delete unnecessary contacts from Telegram on Samsungincluding hidden settings and workarounds for devices with shell One UI.

Why Telegram saves unnecessary contacts on Samsung

The main reason for filling out the contact list in Telegram on Samsung —aggressive synchronization with the phone book Android. The messenger scans:

  • 📱 Local contacts (saved in the phone memory)
  • ☁️ Cloud contacts (Google, Samsung Account)
  • 📞 Journal calls (last 30–90 days, depending on the version One UI)
  • 💬 SMS messages (sender numbers)

On devices Samsung this function works differently than on “pure” Android:

  • 🔄 Automatic synchronization is enabled when you first start Telegram and does not turn off even after manually deleting contacts.
  • 📲 The shell One UI transmits to Telegram not only names, but also contact labels (for example, “Work”, “Home”), which creates duplicates.
  • 🔒 After the update One UI 5.0+ Telegram can restore deleted contacts from backups Samsung Cloud.

Another feature - Telegram does not delete contacts from the Android phone bookIf you erase the number in messenger, it remains in the system and may appear again during the next synchronization. Therefore, to completely clear it, you need to work simultaneously with Telegram and settings Samsung.
