I've got a RAM Xgrip and now with 2 different phones the micro USB connection is unreliable. On my old phone LG G3 the phone would switch from fast charging to slow charging. On my new phone LG XVenture it will turn the screen on. In both cases it seems that vibration is causing the connector to loose it's connection, and the phone thinks it is unplugging/plugging. I've tried different cables and even duct taping the connection, and they all eventually flake out. Has anybody else had this problem, or any fixes? Right now I'm just keeping the phone unplugged, because I'm worried about damaging the phone port. The XVenture has a big battery so it lasts almost 2 days, but this won't work for longer off the grid rides.
