Lumia 930 bad reception
My brand new Lumia 930 has really bad reception, I have 4g network and on my previous Lumia 830 it worked fine, but 930 can't even use 4g because it is always on 2 bars maaaybe 3, I can't talk to anyone, constantly loses connection, wifi also isn't as good as it should be. I've tried switching sim cards, put my sim in friends phone signal is good, and his sim in my phone signal remained weak. So I opent the back cover and found one metal line taped to the battery. Does anybody know what this is, or how to fix reception problem?
