For some reason the signal bars on the note 5 is lower than on my note 4.
I usually get 1 bar on the note 5 but in the same location I get 3 bars on the note 4.
Have you guys noticed and signal issues on the note 5?
This. You would need to check the -dBm strength to see if it matches. The Cell Bars on each phone can be calculated differently -- which can make it looks like different signal strengths.
