There is an old bluetooth headset, that I no longer used, from the list of paired devices on my Nexus7. I have bought a new headset and can't find a way to remove the old one. I have to find the device by turning on/off Bluetooth.
How to Delete paired bluetooth device on Nexus 7
* Go to Settings 》 Wireless & networks 》Bluetooth.
* Press and hold on device you want to unpair/delete. If it promptes, uninstall the device.
* Then scan for devices again. It will automatically disappear from the list eventually.
