Occasionally, one or more apps seem to get hung up re-using old data, i.e., my Weatherbug just stopped updating my location. I know how to go to AppSettings, select the app, wait....wait...wait for my phone to tally the memory, and then tap Clear Cache. Is there a quick way to occasionally clear cache from most if not all apps? I know this will temporarily slow up the apps that get cleared as this data speeds up app restart as well as helps use less data.
