Okay so my nexus 7 wouldn't turn on so I took off the back off and saw that the battery was a little misplaced so I tried pushing it back were it supposed but then my finger slipped and I broke the 2 Wi-Fi pins so my nexus did turn on but I had bad Wi-Fi signal I heard that I can solder two wires to the back cap but I don't know how to solder can I just use wire glue
