android bluetooth problems - avoid interference

The final consideration you’ll want to think about is that Bluetooth radio waves, or wireless waves, can interfere with each other. This means they can bounce off each other or get muddled up and make things confusing from your devices.

With this in mind, you’ll want to make sure you’re limiting the amount of Bluetooth activity in the area where you’re trying to use a device. While uncommon, this could be the problem.

To fix this issue, turn off all the Bluetooth connections in the area. This includes computers, laptops, mobile phones, tablets, and any other Bluetooth devices you may have. Then, try connecting your Nubia Red Magic 9 Pro+ to the Nubia Red Magic 9 Pro+ device you were trying to use. If it works, you know you were experiencing Bluetooth interference.
