Bluetooth technology has become an integral part of everyday use smartphones Samsung Galaxy. From wireless headphones to smartwatches, devices are connected and stored in the phone's memory, but sometimes the list grows to inconvenient proportions. Old or unnecessary gadgets take up space, can cause conflicts when connecting new ones, and sometimes even interfere with correct operation Bluetooth module. In this article you will find not only the standard method of deleting devices, but also alternative methods for difficult cases - when the gadget is stuck in the list or the phone does not respond to commands.

Feature of smartphones Samsung —proprietary shell One UI, which may vary depending on the Android model and version. We took these nuances into account and prepared universal instructions that are relevant for most devices in the series Galaxy (from S21 to S24 Ultra, as well as lines A, M and Fold). If you encounter a problem when the device is not deleted in the standard way or an error appears, the article has solutions for such cases.

Why you need to delete unnecessary Bluetooth devices

At first glance, the gadgets stored in the phone’s memory seem harmless. However, their accumulation can lead to a number of problems:

  • 🔋 Increased battery consumption. The Bluetooth module constantly scans the surrounding area for known devices, even if they are turned off. The more gadgets you have saved, the more often connection attempts occur.
  • 🔄 Connection conflicts. If there is a device with the same name in the list (for example, two sets of headphones Galaxy Buds), the phone may be trying to connect to the wrong gadget.
  • 🛡️ Security vulnerabilities. Old devices with outdated connection protocols can become a “loophole” for potential attacks (for example, through vulnerabilities in the protocol BLE).
  • 📱 Slowdown of the interface. On devices with limited resources (for example, Galaxy A10 or A20), a large list of associated gadgets can slow down the opening of the menu Bluetooth.

In addition, some devices (for example, fitness bracelets or smart speakers) may automatically connect to the phone when you turn it on, even if you have not used them for a long time. This not only drains the battery, but can also interrupt music playback through others. speakers.
