Troubleshoot device slowing, freezing, switching off, or power cycling unexpectedly
This article helps troubleshoot your HTC EVO 4G slowing, freezing, locking up, turning off, or power cycling unexpectedly.
You may have performance issues if your device:
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.
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.
Be sure you clear only the application cache and not the application data.
Verify if low storage space is an issue on your HTC EVO 4G.
Performance issues can arise when the device has low internal memory. Troubleshoot low memory issues.
Close applications that may be running in the background.
Some applications continue to run in the background after you exit that application and can cause performance issues.
Sprint recommends that you close background applications when you're not using them.
Verify if your HTC EVO 4G is overloaded with widgets.
Most widgets such as weather or clock widgets on your home screens automatically update.
If you have too many widgets updating and gathering information at the same time, the device's operating system and available memory may not perform at its best.
You can remove some widgets to help improve performance.
Uninstall recently installed applications.
If the performance issues began after you installed a particular application, try uninstalling it. See if the issue is resolved.
Some applications may freeze or slow your device's performance.
The download process may require you to accept a variety of permissions that allow the application to control or modify your operating system.
Note: To optimize device performance, be sure the device is running the most recent device software. Check for software updates.
