Im new here so dont chastise me to much if I post in th wrong area. Background, I have been playing with a few phones the past few months, mostly iphones, changing screens, speakers, ports etc...more of a hobby than anything. A friend ask If i could change one on the lg flex and after a quick look on youtube, I saw that it wasnt going to be that big of a deal so I jumped in. Everything went good, all plugs seem to go back in place with no problems. Powered everything back on and now all of the data works, can send and receive text messages but it will not make or receive a call. It will show 3-4 bars of signal but when you hit the send button the signal bars drop out and it doies nothing. Any ideas? Thanks, Brad
