Are folks saying that once they get a fix and use GPS on the 810, close whatever program and then come back to it after a time, it still takes several minutes to re-acquire? [...] If the GPS in the 810 goes cold when not used but the tablet is still on... then I'd say that was a problem that could be addressed by firmware revisions or even an add-on software solution.
Does it go cold if a program using it is left on in the background?
