Why does my phone automatically connect to Bluetooth devices?
Automatic connections to Bluetooth devices occur due to the phone’s pairing settings. When you connect your phone to a Bluetooth device for the first time, your phone usually remembers that device and will automatically reconnect when it’s in range. This feature is designed for convenience, so you don’t have to go through the pairing process every time you want to use the device.
Another reason could be related to the Bluetooth visibility settings of the devices around you. If a previously paired device is active and discoverable, your phone may connect to it without additional prompts. This can happen with devices like headphones or speakers, which are meant to connect immediately when turned on near a paired phone.
What should I do if my phone keeps connecting to unknown devices?
If your phone is connecting to unknown Bluetooth devices, the first step is to check your Bluetooth settings. You can go into the Bluetooth menu on your phone and view the list of paired devices.
