Android phones and tablets memory can fill up quickly as you download apps, fill them with media files and cache data for use offline.
The less memory space you have, the more time you’ll have to spend micromanaging your internal device storage. If you find yourself regularly running out of space and needing to manage it, here are some tips to clean up your Android smartphone or tablet:
Delete unused apps
First, take an inventory of your app drawer. Sure, there could be several apps that you use every day. But there could also be some other apps you have not touched in weeks or months. Whether it is an abandoned game, an app you reviewed and never used again, or something you downloaded and promptly forgotten. Deleting those apps one by one can be tedious. But they can equally help you gain back a lot of space.
Add an SD Card and move data there

Many Android devices still ship with microSD card slots. Although they are becoming less and less common on newer devices. If your phone or tablet does have a microSD card slot, you can purchase a MicroSD card and insert it into your device to gain more storage space. The storage you gain can’t usually be used for apps and other system files. But you can store music, videos, pictures, and other media files there. Some apps may allow you to move their cache locations to the SD card too. Even if your device already has an MicroSD card, this is a good option if you want more storage. MicroSD cards are fairly cheap. So you can upgrade and get a lot more storage for a fairly low price.
Save data in the cloud
Files stored in the cloud can be accessed from anywhere via Internet connection. Besides helping to free up space for your device, cloud storage can be used as a back‐up files by providing a second copy of important files. These files are stored at a remote location and can be accessed through an Internet connection.
Clear the cache
You can delete cached data with one click if you have a new Android smartphone. By doing that, you will remove data such as app preferences or old searches but you won’t lose important data such as game progress. It is like clearing the cache on your web browser. Depending on how long it’s been since you cleared your device’s cache, this could release a lot of space.
Root your phone
You can consider rooting your smartphone. Rooting usually comes with two immediate benefits: killing bloatware (unwanted software included on a new computer or mobile device by the manufacturer), and getting immediate access to Android OS updates. One thing you need to know about rooting is that once your phone has been rooted, your manufacturer warranty is null in void. This is probably the number one reason for people not rooting their Android devices.
To avoid the storage space issues in the future, it is better you buy a smartphone or tablet with at least 32 GB of storage. Alternatively, you can get a device that does have a card slot, which offers higher memory capacity.
