The question sounds strange I know. For the last few days I have not seen
4G up at the top of the display of my iPhone 6; it's been demoted to
I'm in the same several locations where I have been, and the signal is always 3 or 4 bars out of 4.
I can't imagine that there are separate chips or antennas for 3G and 4G, so this may be related to my carrier in some way, but I thought I would just check here first in case I'm wrong.
Are there any tests I can do to check this myself? Stand under a tower and use the aluminum foil I normally wear under my hat as a reflector for example? ;-)
My iPhone 6's software is
12.4.3 and I have a notification that
12.4.4 is a recommended update.
