Agreed. The touch buttons and GPS are a huge issue.
I thought the touch buttons were fixed with the last OTA update ... I wouldn't know firsthand, because I haven't installed it. I have learned by now where my buttons are and it's not a big deal to me, provided I'm holding the phone right side up!
I noticed something about the GPS. If my GPS is on already for a while, and I load navigation or google maps, my location comes right up and I start navigating right away. If I load maps/nav first, then turn on the GPS, there's that delay. Once the thing connects, it really works well.
I have discovered a way, that at least with my fascinate, works to completely eliminate that delay. Now that delay for me has never been more than 1-2 minutes, and sometimes there's no delay at all. But when there is a delay, and I load that GPS signal strength app (forget the exact name), it instantly connects. I pop back into nav and I know right where I am. This so far has not failed to eliminate any delay whatsoever. And this is a strong indication to me that it's a software thing. It seems almost as if the GPS needs to be "awakened" by something, and for some reason nav and map apps on this phone don't seem to do it quite so successfully.
I've never had GPS issues where it pins me in a different location, as some have reported, so you can add me to the list of folks pretty much satisfied completely by the Fascinate's GPS performance. It always has my location dead on once it's "awake", and has been as trusty as any Garmin I've ever owned. In fact I much prefer it because of the satellite overlay. I have ALWAYS wanted a GPS that does that. Who in the world knew I would end up buying a cellphone for that purpose. I certainly never suspected such a thing.
But when google maps and google earth were back in beta and being tested and added to and improved upon, I always said to myself, "Gosh, I wish someone would just make a GPS that used google maps/earth and would do a satellite overlay. Imagine being able to see a field on your GPS, and then looking out and seeing that actual field right there in front of your eyes!"
