Is there any further testing I could do or any settings/apps that could help me out? I don't have the insurance through Sprint.
I have the Sprint Note 3. I have a 3 high quality bluetooth speakers and they all of a sudden sound ****ty. I tried with my gf's galaxy S4 and they sound perfect like they used to with my phone. With an aux cable the speakers sound good. But via my bluetooth connection they sound like the volume is turned down to about 30% and it's half blown out.
