Hello all. I just finished replacing the battery of my droid 4, but I'm having some issues with my cell signal. LTE and 3g signals are always strong, but as soon as I make a call my signal strength drops to one bar. I can't send text messages either :(
So I figure its got to be an issue with the cdma antenna. Does anyone have any tips to try and fix this issue? Even the location of the antenna would help...I can't seem to find it.
