I have a Samsung Galaxy S7. Using brand new Liberty 2 bluetooth earbuds.
I was sitting still listening to music in my earbuds then suddenly the music started coming out of my phone. This happened 5 times. I have not seen a solution posted.
Liberty 2 Dropping Bluetooth
In the first instance can you try removing the pairing record from your phone and complete a reset of the earbuds using the following method to see if this resolves your issues
you should delete the buds from the bt-list and pair them again.
This is the first idea I got.
