How to Clear App Cache and Data from Android | Clear cache

Once this sorting is done, you can still save storage space by emptying the cache of applications that are essential to you on a daily basis and that you have therefore kept. This is because each app saves a certain amount of data when you launch it to make future uses faster. Over time, this data accumulates and it may become useful to clear this cache.

From this same window, you can also delete additional files, often called application data, which will allow you to recover some more space. To do this, press Empty storage space (or Delete data on the S21).

This will return the affected application to its default settings, without the need to uninstall it. Very practical in the event of a problem encountered with a program that makes your smartphone bug. Starting from scratch can correct malfunctions.

However, be aware that you will lose all your settings and other accounts. Use with discretion if you don’t want to have to re-enter all your passwords!

Optimize smartphone operation

Deleting an application’s data can remedy occasional instability due to a faulty installation, but it is not always enough. Some apps run in the background, sometimes draining your smartphone’s RAM unnecessarily.

To remedy this, go to the settings of the Galaxy S21 smartphone, in Battery and Device maintenance. Then in Memory. To free up your smartphone’s memory, press the Clean button.

Apps running in the background are briefly displayed. If you realize that among these, some are not essential to you, it may be time to part with them.

To complete this action, go to Battery and device maintenance, then to the Battery sub-menu and finally to Background usage limits. Check that the hibernate unused apps option is activated.

From the Application s submenu, you can also authorize or revoke background operation. Select the app of your choice, then in Application information go to the Battery menu. Check or uncheck Allow background activity.

There is no real equivalent on the Pixel, Google believing that Android perfectly manages the memory used by applications for their operation. However, if one of them is causing problems, you can force close it.

Under the Recently opened apps line, select the one you’re looking for (if you can’t find it, a full list is also available). In the App Info window, tap the triangle icon above Force Stop.

Deleting alerts and other notifications that interrupt the consultation of your smartphone will also allow you to find a more comfortable use of your smartphone.

Still in Application, select on the Galaxy S21 the one that disturbs your use. In Information about the application , press Notifications then uncheck the Display notifications line .

Same thing on the Pixel, select the application of your choice, press Notification s then uncheck All notifications from the app in question. 

If it’s an alert from a website, launch your browser – Chrome for example -. Press the three vertical dots to open the main menu. Tap on Settings then Notifications . Under the line Sites that group all those for which you have authorized alerts, deactivate the line Display of Notifications if you no longer want any. Otherwise, uncheck one by one the sites from which you no longer want to receive alerts.   

Finally, take the opportunity to go to the Applications / Permissions menu to revoke those that are not really useful. If you find that an e-commerce app has access to your camera or contacts, it might be time to fix it. The operation of your smartphone will be even more optimal and the security risks reduced.
