🔹 Automatic connections to irrelevant devices, such as a phone trying to connect to a neighbor's speaker or old headphones that have been in the drawer for a long time, resulting in delays when connecting to the desired gadget.

🔹 Bluetooth profile conflicts: Some devices (such as Wireless Earbuds or Smart Watch) use multiple profiles simultaneously for audio, data, call management. If there are scraps of past connections left on the list, new devices may not work correctly.

🔹 Security leaks: Stored devices may contain past connections to public speakers (in cafes, vehicles) or other people's gadgets, and in rare cases, this is used for Bluetooth attacks (e.g. BlueBorne).

🔹 Slowing down the search for new devices: The more entries in the memory of a Bluetooth module, the longer the phone scans the airwaves when searching for new gadgets. 5A) It can take up to 30 seconds instead of the usual 5-10.

🔹 Errors in updating MIUI. When switching to a new version of the firmware (for example, with the MIUI 12 on HyperOS) old Bluetooth settings may conflict with new drivers, resulting in loss of sound or inability to connect to devices.
