Iphone12 sudden low signal reception
Two iphone12s are in direct view of a cell tower and have had 4 bars until just recently, now 1 bar. I have looked up the raw signal (rsrp) - it is -117. Poor to no signal. How do we know whether it is cell tower or antennas on our phone antenna or a sw issue? Might it be a sw issue forcing folks to iPhone 14?
