How to clear cached data from Android apps
What you'll need: Any Android device. The exact steps may vary slightly by manufacturer, but the general process remains the same.

Each option explains what it does and how it affects your experience. For example, clearing cookies and site data will log you out of many or all websites, while clearing cached images and files might cause Chrome to load images slower next time you visit a site.

3. Optional: A simpler shortcut
On newer versions of Chrome for Android, tapping the menu button displays an option called Clear Browsing Data. When you select this, a pop-up will appear asking you to clear browsing data from a specific period. If you select More Options, you'll be taken to the Browsing Data screen, where you can choose the data to delete and select the time range.

Cache stores temporary files -- like images, scripts, and other resources -- to speed up apps and websites. Clearing it removes these files without affecting personal settings or login credentials.

Will clearing cache delete my app data?

Will clearing cache make my device faster?
Yes. It frees up storage and removes potentially corrupted or outdated files, which can resolve slowdowns and glitches.
How often should I clear cache?
Whenever you notice slowdowns or app glitches. For most users, every three to six months is sufficient.
