There is a type of Bluetooth mouse that automatically connects to devices like the 6125/6225/660 every time the box powers on. However, it does not automatically reconnect on the Android 15-based 6350. The reason is that this mouse does not automatically reconnect to Android devices running Android 15. Connecting it to an Android 15 smartphone yields the same result. This is an issue with the mouse itself, not the product. We recommend replacing the mouse.
