Once outside when I put the iPhone in my back pocket the RFLK+ head would not transmit/communicate with the iPhone. I called Wahoo several times trying to sort it out with no luck and they offered to take everything back for a refund. Maybe they sorted out that bug.
According to Wahoo, if you put your phone in your jersey pocket, it should be in one of the side pockets and should have something between it and your jersey. This keeps your perspiration from blocking the signal, especially if placed in the center pocket. Putting your phone in a saddlebag or on your handlebars will solve any dropped signal issues.
