If you have problems with Bluetooth, which disconnects all the time, or sometimes does not even respond, you can try some of these tips.
Starting with the simplest method, clear the Bluetooth cache . To do this, go to Settings >> Applications >> Bluetooth >> Clear Cache >> Clear data. Once you do these steps, restart the Samsung A10.
Now the second step is to delete all the devices that you have connected with Bluetooth and start from scratch to pair them. Try one of the devices first to see if the Bluetooth is working properly, and then add new ones.
Also, make sure that you do not have any power saving settings activated that could disable Bluetooth operation.
