There are a few ways to determine the Bluetooth version in Android. The easiest way is to open the Settings app and look for the Bluetooth icon. If the icon is not present, then you can check if Bluetooth is enabled by going to Menu > System > Bluetooth and checking the box next to “On.” If Bluetooth is enabled, then you can see a list of devices that are connected to it by looking at the list of devices that appears when you press and hold on one of those devices. If there are no devices listed, then Bluetooth is not enabled.
