AT&T’s Captivate and T-Mobile’s Vibrant are among several Samsung Galaxy S-branded smartphones that have been plagued by GPS issues since they launched. While this isn’t the first time the manufacturer has issued a supposed fix, Samsung today announced the availability of a new app called GPS Restore — which has the sole purpose of restoring a device’s GPS settings to their original state. We’re not sure how this would help resolve any issues, unless Samsung is suggesting that some carrier tweaks are responsible for the problems. In any case, owners of with the Captivate or the Vibrant will undoubtedly be happy to give Samsung’s new GPS Restore app a whirl. Simply search the Android Market for “GPSSamsungRestore” to give it a go.
