Just curious because i went on a trip to a area where i had the phone say no service so while i was resting i went to clean my phone so i took the  bumper off and i was surprised to see i had 1 bar of service. I put the bumper  back on and after a few min it went down to no service again, with that i left the bumper off while i was away.
