I use Spotify for all my musical needs. I have a small shop that I use my phone to connect to a Bluetooth speaker and play music so it's not uncomfortably silent for the shoppers. Randomly, and often, and for annoyingly LONG periods of time, the sound will fade as if I'm getting a notification, except I'm NOT getting a notification. This happens on three different Bluetooth speakers, and even when I'm just playing the music out loud when I'm doing chores. Sometimes, it just pauses on it's own too. I've reset the phone multiple times, and each device, disabled Audio Effects, turned on Do Not Disturb mode, silenced all notifications, and nothing works. Nothing helps with the random muffling. Location is not an issue, as my dad uses the same phone as me and does not have this problem. Please help before I throw my phone off a bridge.
