I have a blue vivo xl2. I replaced the LCD screen. It was my first time replacing a screen. I don't know if I damaged anything I put everything back the same way. But now I can't call or receive calls. Everything else works the messages and internet. Now the signal is weaker I have no service in spots I used to have it in. Everything else works fine. It shows my signal bars high and I still can't make a call its stuck on dialing and it won't dial a thing. I took everything apart again and I still can't find anything wrong.
