My Edge 130 Plus causes a bluetooth slowdown on my phone also affecting the Wifi capabilities of my phone. I unpaired my edge 130 and my phone worked fine. After pairing it is back to not working. It's like jamming up my bluetooth (even when the edge 130 is off it seems to be stuck looking for it or something). It's gotten so bad that I turn off bluetooth so that my phone wifi will work. When I turn bluetooth on to sync an activity from my garmin watch it gets stuck spinning until I turn then edge 130 plus on and then suddenly my watch can sync.
