So this problem began a few months ago.... It started saying no mobile network available and I wasn't able to call anybody or text anybody then it would go back to normal. Around a month ago it stopped working completely it said that no mobile network was available and I haven't been able to make a call since. Along with a no mobile network available I hear static whenever I swipe across my screen from somewhere near my charging port. I just fixed my charging port and speaker to see if those were the problems and it has not fixed my issue. I have tried all the troubleshooting and I believe that there is something wrong with my antennas or something because I get service like 5% of the time now..... If anyone can tell me what I need to do to fix this problem I would be forever grateful. I have a Samsung Galaxy S4 Verizon version. Thanks!
