In most cases, you are likely to meet the internal storage full on the Android phone after a long time of use, especially the fast increasing quantity of installed program, user’s files, program caches, system settings, and other data.

Quick ways to free up space on Android phone

When your Android storage is full, you will not be able to store any new data. Thus, it is necessary to learn how to free up space on Android internal memory. Here we share 3 quick ways you can have a try.

1. Clear all cached app data

In the Apps storage setting screen, tap on each app and you will find each one has its own “cached data”, which can be a few kilobytes to hundreds of megs or even more. These caches data are just junk files and you can delete them to free up Android storage space. Just click on the “Clear Cache” button and wait for it to be done.

2. Remove unnecessary apps

If you have downloaded many programs or apps, you can try to uninstall some of them you don’t use usually in weeks or months. Some apps always take up a lot of space and deleting them can help release much storage space. You can sort your apps on your Android phone in size and decide which one to remove.

3. Transfer media/photos to the cloud or a computer

If you have stored a large number of precious videos and photos on your Android phone, you can transfer them to a cloud drive or a computer as a backup, and then delete them from your device permanently to free up space on Android internal storage.

The above quick ways such as deleting unused applications, all the history and caches might be helpful to release Android internal memory. But they cannot solve the problem totally and the internal memory on Android phone will get full soon or later. What is the best solution to getting more space on your phone without deleting anything?

Apart from trying to delete unnecessary data to free up space, you can also attempt to get some extra space from external memory card or SD card. How to make some space on SD card or memory card available and readable on Android phone?
