I have the same issue, but the issue was caused by me dropping the phone. I dropped it on concrete, the back cover popped open in some places, of course I was furious for me being so clumsy , i closed the back cover and put the phone back in pocket... 2-3 hours later I was on but, took the phone out to surf the web or whatever, noticed EDGE indicator, I was confused cuz I was in a H+ area and this shouldn't have been happening. Got home I have a 3G zone there, but nothing. I downgraded to 4.4.4 from lollipop, didn't help, reflashed to 5.0.1 didn't help, I couldn't fix it. Sometimes in some places it gives me 3G or H+ but the coverage indicator is half greyed out, on EDGE it's always full. So I don't know what to do. I don't have warranty any more, I can't even RMA the device. Can anyone help? Will it be a good idea to replace coax antenna cables?
