How to Clear the Cache on OPPO F21 Pro 4G

Internal memory of OPPO F21 Pro 4G gradually fills up during usage. Users can clear the cache on the OPPO F21 Pro 4G, after which the memory will become available to its fullest capacity.

What is Cache and What is It Used for?

Cache is an intermediate storage that collects data for its faster access. Let’s look at a web browser for a clear example of the importance of such storage. For example, a OPPO F21 Pro 4G user often visits the same site. On their first visit to the website, opening the page takes 3 seconds, and on the next visit it only takes 1 second. Thus, using cache saves time.

Cache is built up by a variety of applications. These can include browsers, image processing software, video editors, social networks and games. Despite the obvious benefits of using cache, this temporary buffer has a significant drawback. It takes up a lot of free space in the internal storage.

Since important files like account passwords or multimedia do not get stored into the cache, you can get rid of it without any consequences. As such, owners of OPPO F21 Pro 4G will not only get additional space on their internal storage, but also speed up the device.

Ways to Clear Cache on OPPO F21 Pro 4G

OPPO F21 Pro 4G offers its users several ways to remove excess data, including cache. The user can perform the operation both by built-in means (manually or automatically) and through special applications.

Manual Cache Clearing

Since the temporary buffer is formed by applications, this way can be performed by manually clearing the cache of individual apps one by one. You will need to:

Open the phone settings.
Go to the Applications section.
Select the required app.
Open the Storage section.
Press the Clear cache button.

Clearing the temporary buffer should not be confused with flushing application data. Only unnecessary information gets deleted in the first case, while the second clears account settings and other important info.

Automatic Cleaning via Settings

The OPPO F21 Pro 4G phone has a useful feature that allows you save up time by avoiding clearing the cache of individual apps. The system is able to independently determine the list of unnecessary files and delete them. To automatically remove excess data, you will need to:

KeepClean;
Cleaner;
CCleaner.

All apps work on a similar basic principle. Therefore, taking a look at the way such applications function based on the example of CCleaner would be enough. The utility is one of the most popular and is available on both smartphones and PCs.

Excess data cleaning via CCleaner is performed as follows:

Run the application and allow access to device storage.
Press the Quick Clean button.
Wait for the scan to finish and mark the files you want to get rid of.
Press the Finish Clean button.

The screen will display information about the successful completion of the operation after deleting the cache. You can then uninstall CCleaner or leave the application to perform more cleanups in the future.

How Often do Users Need to Clear the Cache?

Cache is not only important data that allows you to launch applications faster, but also excess files that takes up free space in OPPO F21 Pro 4G’s storage. The temporary buffer is replenished daily, and the rate at which new excess data appears depends on how actively the owner uses their smartphone.

As a preventive measure, it is recommended to clean the cache monthly. But in some situations, disposal of such excess data is strongly required. For example, if:

the device is buggy and unstable;
the internal storage has less than 20% free space;
individual applications do not launch.

If none of the conditions are met, you can safely do without clearing the cache. But keep in mind that large amount of excess data may present itself at the most inopportune moment, so you should not forget about preventive measures.
