I'm using Papago M9 with Malaysian map updated 6/11/2012. Very accurate and does not use internet data.
Junction view is awesome.

Phone is definitely yellowish.

Same happened with my old note 2. It was very yellowish. Flashing the perseus kernel reduced the yellow tint but still it was there. I am using a calibrated Dell U2412M IPS monitor, so the whites are white and comparing with the phone, the yellow is quite apparent.

The monitor on the screenshot is of a TFT display so it isn't as good as an IPS. Anyways, took a look at my aunt's SGS3 , and surprisingly the whites on the phone is really white and there isn't any hint of yellow on the SGS3. Hopefully my next note2 would be free of this.
