8BitDo Ultimate 2.4g/Bluetooth Wireless Controller randomly disconnects
The Problem
While playing games with the 8BitDo Ultimate 2.4g/Bluetooth Wireless Controller, sometimes it randomly disconnects and reconnects, and then you get completely ruined by the Elden Ring boss you were fighting.
The Solution
The little switch on the back that toggles between 2.4g and Bluetooth mode is extremely sensitive, and is prone to getting jiggled in the heat of gaming, causing the controller to try and change connection modes.
Put a piece of tape over it to keep it in place.
