Simulator vs. Real device

In the sim, by default they run in high power mode, but you can switch to low power (and should to test).  There are other things in the sim like turning off activity testing.  And for some things you want to simulate data or play back a fit file.  There are some things you don't see in the time, like notification messages.  On MIP devices colors can look different than on a real device.

What kind of things are you running into?

A simple watch face that only shows the time, for example, with real forerunner 45 or vivoactive 4 devices, nothing appears on the screen but in the simulator, with high or low power mode selected, it works perfectly.

Post your code.  (use a code block in the forum (insert>code)

sounds like 2 bugs:

1. the colors you use in your app

2. (maybe?) a bug in the sim that does display them even though the real device doesn't.

Do you mean that there are colors in some devices that make apps not work?

In FR45, FR55 there are less colors, so a color that you see on another watch might be mapped to the background color

I think that’s the problem I have.

Thanks.

and remember that some devices have different name and they are "the same" like other (e.g. firstavenger is probably v4)

with this devices is another problem they serve onExitSleep in strange way so you have to move some code to onUpdate (of course if you use in onExitSleep sensitive code)

Garmin people make it very difficult for us.
