So I've been using my cell phone for strava and it was working like a charm til I got a new update to the OS on the phone. After the update the reception is horrible, I come home and a bunch of segments were not recorded.

I'm using an android now, but I'm contemplating getting something like the Garmin 520. Are the dedicated bike computers' GPS better than what we find in a cell phone? Im guessing my issue will be resolved in a future update, but I guess I could find myself in a similar situation again when I rely on the phone..

Tldr: are bike computer's GPS signal better than that of a cell phone?
