Many years ago, in the days of the mythical iGO 6, there was a phenomenon that personal navigation devices [PND], their GPS would go wrong as a result of magnetic inspiration and just so affected the position of the cursor and navigation. The phenomenon was known mainly in "French vehicles" and because of metallic components that were assembled in the front window and there and of course, the PND was located.

Maybe at intersections, there are traffic lights or microwave systems that are too powerful in their impact and inspiration on your specific and "problematic" device?

Maybe a collection of a bit of all of the above makes you this “salad” and not sure false will be solvable, other than switching to a better or more immune device.

What car do you have?
Is there anything glued to the back of the device that is used to settled on a "magnetic" stand?
Do you have any magnetic component on the roof a/o in the area where your mobile/tablet is located?
Does the phenomenon that occurs to you, also happen in another vehicles?

Almost anything can be the cause and the effect, and the "weird" should not be ruled out either.
