What is the Cache System on Android Phone

The Android operating system uses a cache system to speed up its performance? But do you know what is the cache, and how does it works? Here is a little explanation.

For those of you who use an Android phone, you may have noticed the first time you load an app. To open the app the first time usually takes a longer time, compared to the second or third time. Well, this is where the cached data works.

Basically, the cache file on an Android device is a collection of images, videos, text files or others that are needed to display web pages, advertisements and more.

The cache file will store the elements of the image and other features, which should be downloaded from the internet, or extracted from compressed application files or must be generated quickly, such as thumbnails of photos. Then these files are saved into the cache system on android storage.

So when the second or third time you open an app can pull the file from local memory, the app can load faster than when you first time opens the app.

But even though it can speed up application access, the cache system can also make memory run out quickly. Because the more elements stored in memory, the more internal memory of the phone will be burdened.

Therefore the cache system must be periodically cleaned or deleted to restore the internal memory capacity as before. Here's How to Clear Android Cache Quickly Without Any Apps.
