I am developing an Android app which uses Google Maps Android API v2. While testing the app on several devices, I noticed that one device (Galaxy S4) has started displaying extra copyright information along the bottom right corner of the map (in addition to the usual Google logo displayed in the bottom left corner of the map):
The extra text
© 2015 Google - Map data © 2015 Google
does not appear on other devices. It also does not appear in the stock Google Maps app on the affected phone.
Does anyone know why this information appears, and why it appears only on some devices? Obscuring the copyright info is not permitted by the Google Maps Terms of Service (refer to the answer by @miselking for more information), but I'd like to understand when it will/won't show so that I can accommodate it in my layout in an appropriate way if necessary. For example, I already use padding at the bottom of the map to avoid covering the Google logo with a legend. The padding moves the extra copyright information up too, with the following (awkward-looking) result:
I've noticed that this Google video on map padding displays a variant of the copyright text in the bottom right of the map, and also confirms that the copyright text is supposed to be shifted by the map padding. In this case, the copyright information reads
© 2014 Google - Map data © 2014 GBRMPA, Google, MapIT
There is still no indication given as to when this information may or may not appear, however.
