I have recently tried the LC3 codec on my Pixel 7 device with my EarFun Air Pro 3.
After activating the LC3 codec on my phone it worked for a while, but I started experiencing connection dropouts.
Eventually after putting the buds in the case and getting them out they would not play any sound anymore using the LC3 codec.
So I am back on APTX adaptive again and the buds again work as normal.
Also when I used the LC3 codec I don't have any access to the EarFun app.
Can this be solved via a firmware update? Right now I can't really stability use my buds using the LC3 codec.
