I've been using google navigation for the past six weeks since I got my phone, but the past couple days I've noticed some problems with it. Seems like when I've input a destination for turn-by-turn directions, the current location marker will get stuck (in the middle somewhere of my trip) and won't advance, causing me to miss a turn, and not auto-correct itself. This issue wasn't happening in the past until recently. Anyone else having this issue too?
