Bluetooth

Have you installed a LED light strip/bulb?

If so, you would need to uninstall the related App to disconnect from that apparatus. Of course, doing so, would mean no control of the LED device.

Bluetooth Said:

"There is a random bluetooth device that connects to my phone, I have no option to remove it. Unsure of what it is and what to do to fix this problem"
