Hi, I just got my Nexus 5 from a Koodo retailer. I have problem with maintaining a signal. My other phone gets consistently 2 bars (Samsung Slyde), but the N5 get an empty triangle most of the time, sometimes the placeholders for the 4 bars are indicated, and one time I noticed 1 bar. I have G3 selected, and searching for network is a hit and miss. I have seen Rogers, Telus and Koodo on occasion. I am disappointed about the sensitivity of the phone, but maybe the settings are wrong? Advice appreciated.
