Google maps with ng-map sometimes has problems on Android

Hey guys,

using ng-map which is basically a wrapper for the Google maps Javascript API v3, I get wonderful results on both Android and iOS using ionic.
However, at times in the Android version, the maps pane stops working properly and I could not yet correlate it with any user action. Also, there are no console errors or such.
Maybe you have an idea why this problem arises, looking at the screenshots before and after working properly on Android:

Notice that the Terms of Use are somehow displaced and the upper switch for Tarrain/Sattelite looks different.
Cheers.
