Hi folks. On my Vibrant (unrooted), various recent updates to Google Navigation have rendered that app essentially unusable. Basically anything post-ROM has an issue where when I start navigation, even when it does pick up a GPS signal and try to navigate it has a good chance of freezing up completely. It seems to happen unpredictably, but with increasing frequency. It will even happen just driving along doing nothing but letting the app guide me. It will just lock up cold. Sometimes the screen goes blank. The only way to get the device to respond at all is to pop the battery out momentarily. Naturally this renders the GPS all but useless. Has anyone else run into this issue? Anyone found a solution?
