The bars are a meaningless.
It's better to compare the actual signal strength in dBm.
Just got the G3 after my 3 week old nexus 5 packed in,
Whats going on with the screen , ebay app only has enough to show 3 things my old z ultra with less pixels used to show 5 or 6 ( my missus's moto g 2nd even shows more ).
Same with other apps like tapatalk and facebook , it shows way less content.
Thought I had mistakenly enabled some accessibility mode for the blind.
The G2 & G3 both drop the signal in weak areas and take ages to recover. I can manually do it by turning on then off flight mode but it drops again after a while and looses signal. The iPhone Keeps a constant signal albeit it fairly weak but it does not drop the signal all the time.
