Cache on a phone is a temporary storage location where frequently used data, app files, copy of web pages, images, and other resources associated with the website are stored on an Android device. Cached data can include downloaded images, audio and video files, website data, and more. The cache allows for quicker access to frequently used data and can improve app performance. For example, if you frequently visit a website, the images and other data from that site may be cached so that they load faster the next time you visit. However, cached data can quickly fill up your phone’s storage, and if it is not cleared periodically, it can start to take up valuable storage space. Clearing the cache on a phone can help free up storage space and improve the phones performance. The steps to clear the cache may vary depending on the device, but it usually involves going to the devices settings and selecting the option to clear the cache.
