I have a problem whit my Epix 2 the white spots appear yellow


My point is, if your pics are showing the color of your hand incorrectly (I assume your hand is not the color of a steamed lobster), then they are also showing the colors on your display incorrectly.
To demonstrate my point, here is your last pic with the overall color balance to show your skin tone more realistically and your floor color as brown wood:

And voila! The images on your screen are white!
HTH
The whites on my Epix screen are very white. Clearly you have tried restarting since the startup screen is one of the photos. Therefore, if yours has a yellow tint I would suggest you reach out to your local Garmin support for a replacement. Has it always been this way since you bought it or did something change?
