You may have an unstable application if it:
These steps help identify and resolve the underlying cause. After completing each step, test to see if the issue is fixed. If not, continue to the next step.
Perform a soft reset.
A soft reset deletes any temporary files that may be causing the issue.
Identify the applications currently installed on your HTC EVO™ V 4G.
Clear application cache.
Each application has a cache of temporary files that may be taking up memory.
Try clearing the application cache from your larger applications to free up space.
Continue to clear the cache on the rest of your apps.
You may not be able to clear the cache for every application.
Rarely, an application may not function as expected afterward.
Try clearing your application cache first and test to see if that resolves your issue.
Clear application data.
Caution: When you clear application data, you're permanently deleting your user information, settings, high scores, credit card information, and other files that weren't downloaded originally.
When you clear application data, the application resets to look like the first time you opened it.
Uninstall and reinstall the application that isn't working.
A complete application uninstall removes all related files, settings, and data from your HTC EVO V 4G. After the uninstall, reinstall it to try to fix any download errors and to be sure you have the latest software version of the application.
Note: To optimize device performance, be sure your HTC EVO V 4G is running the most recent device software. Check for software updates.
