Android as an operating system has become quite efficient in recent years. Google has focused a lot on its file management system and apps have gotten a lot cleaner. The engine that drives ads on your Android device has also become a lot faster and more efficient. But this has come at the cost of storage space, your OS files have become larger, apps have become heavier and games have gotten more resource-intensive.

With all this in mind, it is no surprise that your Android device can fill up quickly despite its large storage capacity. While you can quickly identify which photos, videos, files, documents, apps, and games are consuming the storage real estate, some files might be put under the ‘Other’ category by the system.

The system basically puts any unidentified storage files under the ‘Other’ in your Android device’s stock memory analyzer. If you have been looking for a solution to this problem, then you have landed at the right place.

We have compiled this comprehensive guide that will cover all the reasons for your storage filling up, and provide most if not all the solutions that will be applicable to your device. Let’s get started.

What’s in ‘Other’ category in your device storage usage list

Here’s what is filling the storage marked as ‘Other’ on your device.

Private App Data

The most prominent reason for your storage space filling up under the ‘Other’ tag has been identified to be Private app data. This could be additionally downloaded files, failed OTA updates, cloud sync files and much more.

Most apps and games nowadays have smaller installation files but require heavy downloads over the Wi-Fi to be completely operational. Moreover, there are apps that will sync to the cloud and constantly download and upload data depending on your preferences.

Furthermore, streaming services can often glitch out and fail to delete cache files which can also clog up the storage space on your Android device.

Failed Backups

Google gives you the option to backup your mobile data to the cloud in Google drive. There are also other services that allow you to do the same with attractive pricing options.

Keeping your device synced to the cloud has a lot of advantages, you will have a backup of all your data even if you lose it, you can access all your files on the go despite having low space on the local storage of your device.

Cloud services also offer perks like password vaults, game data backups, free storage space, file hosting and much more. But often these services can glitch out due to regular updates and new features.

Even though most of these issues get fixed instantaneously, there can be failed backups on your device locally that might not be recognized by the backup service itself. There can also be duplicate files on your device that might be taking up extra space which will show up under the ‘Other’ category.

Failed OTA Updates

New devices are usually eligible for a few major OS updates in their lifetime and regular security updates as well. Since the past decade, most of these updates have been provided OTA which is easier for the consumer as the device can be updated remotely without the need for a PC.

On the other hand, the drawback of OTA updates is that they can easily fail on a slow network or a network that frequently resets. Higher internet ping can also lead to the failure of OTA updates and not to mention that they are virtually impossible if you are traveling for long hours.

All these half downloaded updates and temporary installer files can also show up as ‘Other’ data in your device and might require you to clean it up manually.

Hidden Cache & Temporary Data

Your browsers, apps, and games constantly connect to the internet and download a lot of data in the form of text, images, and videos. These could be consumer files, ads, content and much more. All of these files are usually programmed to get cleaned upon exit in order to keep your local storage free from clutter.

But there are instances when these files get leftover, this is a common occurrence in the case of mobile browsers. If you fail to clear up your website data then your browser’s local storage could end up taking a significant amount of storage on your device.

All of these temporary files and cache files will show up as ‘Other’ when you analyze your filesystem using Android’s stock settings app.

How to free up storage space and clean ‘Other’ section in storage

Here’s how to clear the files and data in the ‘Other’ category of storage.

Use ‘Clean up’ option on your device

Almost all Android devices these days give you an option to clean up the storage of your device in the Settings app itself. Here’s how to use it:

  3. Under Storage, the UI may be different for different Android phone, but you can tap on any item to find more info about its content, and then can selectively delete stuff.

Use a Storage Analyzer/File manager app

The best way to get a good solution is to understand your problem completely. Having an efficient file manager will help you get a more clear look at the larger files on your local storage.

You would be able to sort them according to their size which will help you identify large files much more easily.

Check data used by proprietary apps

Android’s in-built stock memory scanner can also be a huge help if your app data is clogging up your local storage. To make use of this feature follow this simple guide.

  1. Open your ‘Settings’ app.
  2. Navigate to ‘Storage Options’ and open it.
  3. If your manufacturer allows, then sort the apps according to their size. If not, then manually scan the apps to find the ones with exorbitant data sizes.
  4. Open the app and click on clear cache.
  5. If that does not help, then click on clear all data.

Note: If you click on clear all data, you will have to login again into your app and download the additional data that might have been needed at the time of its initial installation. 

Check Android/obb & Android/data directories

Deleted apps are often leftover in your filesystem due to certain glitches of incompatible updates. These leftover app files are also caused due to third party launchers that have not been optimized for your device.

If you are unable to clear your ‘other’ storage using the above-stated methods then you should resort to this method. There might be leftover app files from your deleted apps in your local storage which you might need to clean manually.

  1. Open your desired File Manager.
  2. Navigate to settings and enable ‘Show System Files & Folders’.
  3. Now Navigate to ‘/Android/obb’ in your file manager.
  4. Most files in this section of your local storage will be named in the following format ‘com.ABC.XYZ’. ABC being the developer name and XYZ being the App name.
  5. Scan this section for names of deleted apps and delete the ones that you find.
  6. Once you are done in ‘/Android/obb’ navigate to ‘/Android/data’.
  7. Follow the same steps as the previous folder to identify left-over data from deleted apps. Delete the ones that you find and then check your ‘Other’ storage.

Move data to SD card & reset your phone

If the above-mentioned methods fail to help clear the ‘Other’ storage section on your local storage then it might be time to adopt severe solutions to solve this problem.

You should start by using the SD card method as it’s faster, easier and does not require a full backup of your device. Follow these steps.

  1. Insert a high capacity SD card into your device. If your device does not have an SD card slot then consider using an OTG card reader.
  2. Now create a manual local backup of all your important data files.
  3. Locally backup your contacts and saved passwords onto the SD card.
  4. Now reset your device to its factory settings.
  5. Set up your device as new and restore your files and local contacts backup from your SD card.

Your ‘Other’ storage should have cleared up and things should be back to normal by now.

Go back to stock ROM if you are using a Custom ROM

If your device is rooted and you have been using a custom ROM then there is a high chance that your custom ROM has glitched out. A few major custom ROMS including the likes of Lineage OS, Pixel OS and more have experienced bugs where the file system ends up duplicating itself numerous times.

This can clog up the memory on your local storage which could end up as unidentified files in the ‘Other’ section of your memory scanner. A good idea to solve this problem if the above-mentioned methods do not work is to revert back to your Stock latest ROM and wait for an update from your Custom ROM’s developer.

Additionally, you could also raise a help request on the developer’s Github account in case he/she is regularly active and responsive to bug reports.

Clear device cache in Recovery mode

Another method to try and clear your ‘Other’ category in your file system is to clear your UI cache in Recovery Mode.

Note: Recovery mode is a sensitive menu with options that could potentially brick your Android device if they are messed around with. Proceed with caution and if you are not confident about your technical prowess then you should try the next solution.
