How do I clear the cache on my device?

Your cache is a temporary data storage area for information that your device may use again in the future. For example, if you visit a web page, the cache may store a copy of the information on the website so that it can load quicker if you visit it again. Your cache may be storing unnecessary data and could be taking up space on your device. If you are running out of storage space on your device or find that it is running slowly, it may help to clear your cache.

Why are some Android apps crashing?
