Sometimes the favourite gears us red and sometimes yellow.
What decided the color?

Red heart means you favorited the cache.
Ah, that makes sense, thanks
A lot of GPS weirdness like this ends up being surprisingly device-specific too. I had one phone that constantly drifted or lost lock while another on the same app worked perfectly. Clearing the AGPS data and forcing a fresh satellite download helped a ton in my case.
