When you click somewhere on screen and show point info the screen goes blue or white (or half blue and half white) and you have to click again somewhere to redraw the map
Sorry, but I don't want to mess up my phone now with apk from other sources (have to change security settings, antivirus), but if helps the phone is Samsung s7390 with Android Jelly Bean 4.1.2, single core 1 Ghz, 512 MB ram. The previous version of navigator didn't have this bug.
