Thanks. Yes, i tried all the usual. Upgraded app and fw on the amp. Even used my wifes samsung galaxy S5 to see if it was better on that phone. Forgot the phone and reconnected several times. I do have a watch connected to my phone via bt and a couple other bt connections. When I turn them all off it does better but still very slow loading presets and default tones. I keep the phone right on the amp as if I'm any further away it starts losing connection and has to reload and that takes along time to reload. I like the concept and some of the amps a lot, but if there isn't a plan to update the sw from line 6, I'll sell it. I heard it works better with an IOS devices.
