bridge the antennas
The black line separates the antennas When our hands bridge the antennas (Wi-Fi / GSM )thats when the signal fails , im guessing thats why the stainless steel frame is not one solid piece and thats why apple made the bumpers . try it out by placing your finger only on either side of the black line left side on the and then try it by placing your hand on the black line on the left side bridging the antennas.
