I have issues with my s8 Bluetooth. Whilst it will connect to my speaker and headphones with no real issues it has some serious issues connecting to my Marshall code 25 guitar amplifier. The amplifier has been tested with other products as ok, but the s8 connection is awful. It appears the Bluetooth range is very limited and the problem is exacerbated when anything else is used, even unlocking the phone. Surely this problem is a software one, but is a fix on it's way?
