Understood
For me though there are two reasons that I personally prefer Singal Bars as opposed to dBm.
First, I do not have a degree in Engineering, and I also do not have much knowledge of signals, signal strength, and the technical aspects of signal reception.
Personally, my only knowledge of dBm signal strength is that the Higher the number, the weaker the signal, and the Lower the number, the stronger the signal.
The other reason that I prefer Signal Bars is I want to be able to look at my phone and, quickly determine the signal strength that my phone has at the moment. Personally, I do not want to have to mentally figure out if -100 dBm means I have weak signal strength or medium signal strength.
Forgive me AJ and Robert if my post sounds to harsh, but I just wanted to state my thoughts.
