Android devices are known for their user-friendly interface and customizability, backed by a hefty storage capacity. No matter which Android device you get, storage is rarely a problem. However, if you do run out of storage, it can be a frustrating experience as it hinders the performance levels of the device. 

“Storage Space Running Out Some System Functions May Not Work” is a typical Android error that pops up whenever the device has reached a point where its apps cannot function properly due to a lack of free storage space. This article will cover everything you need to know about the error and ways to fix it. 


What causes “Storage Space Running Out Some System Functions May Not Work” to appear?

“Storage Space Running Out Some System Functions May Not Work” is pretty self-explanatory as an error. It appears whenever your Android device fills its storage to the point where it cannot function properly. Here are some reasons why your storage might be filling: 

1. Cache data

Each Android app saves cache data to run seamlessly during multitasking. In this data, the operating system keeps app content that can be preloaded whenever a user opens the app again. While this data is beneficial for the most part, it can pile up over time. 

Cache data can take more storage than the storage taken by the app itself during the download. Now think of each app doing this. Unsurprisingly, cache data could cause storage issues on your device. 

2. Media

Android phones come filled with high-quality screens and cameras. While this is useful to work with, it does compromise device storage as each video or photo you take or download takes more than usual space due to quality. 

If you store a lot of media content on your device, such as movies, music, etc., your phone’s storage will likely fill up much faster than if you don’t. 

3. Large system files 

Android has many system apps that take up more storage space than you would like. Some manufacturers ship their devices with a ton of bloatware as part of loyalty programs and brand deals. Sometimes updating your phone or apps can also create many large system files. 

4. Malware or viruses

Android users are prone to malware or viruses, considering how easy it is to install content on the platform. These malicious files operate like a parasite on your devices, interrupting storage space while causing other apps to work improperly. 

If you downloaded a file from a third-party website or application, check for its legitimacy and see whether the file you downloaded was safe using an anti-virus or searching online.


How to fix: Storage Space Running Out Some System Functions May Not Work

Storage on your device can be filled for various reasons. Therefore, you can take several approaches to fix “Storage Space Running Out Some System Functions May Not Work.” Here are some of them: 

1. Clear cache data

To clear cache data from your Android device, follow these steps below: 

  • Step 1: Open the Settings app on your Android device.
  • Step 2: Go to Apps/App Management. 
  • Step 3: Toggle apps by storage consumed.
  • Step 4: Run through all the apps that consume a lot of data through the cache and clear the cache individually. Consider clearing the cache using third-party apps during desperate situations. 

2. Delete media 

Media can take up a lot of space on Android devices, resulting in errors like “Storage Space Running Out Some System Functions May Not Work” to appear. You can consider deleting unwanted files to clear storage from your device. 

If you wish to keep the media content on the device, you can move it to a cloud storage or hard drive. You can then view it whenever you want from there. 

3. Uninstall apps

Uninstalling apps is a great way to clear Android storage. With so many apps on the store, we tend to install and forget about them afterward. This can build up over time, filling your device storage. 

Browse through all the apps on your device and uninstall any unwanted ones. Some of these apps might be bloatware that came preinstalled with the device. Uninstall these if you can. 

4. Use a Micro SD Card

Most Android devices come with an SD card slot to extend device storage. If the internal storage is insufficient, consider installing an SD card to move all media content and other data to it. 

Some devices come with a hybrid SD card slot, allowing users to add an extra SIM or an SD card. If you are clutching at straws with storage and can sacrifice the additional SIM card, go for the SD card. Buy one that provides enough storage for all your needs. 

5. Factory Reset

When nothing seems to work, factory resetting Android devices is always an option. Doing so deletes all user data and loads up the device as it comes out of the box. If you will do this, create a backup that you can use later. Here is how to do it: 

  • Step 1: Open the Settings app on your Android device.
  • Step 2: Go to About Phone 
  • Step 3: Find Factory Reset/Erase all data
  • Step 4: Perform the Factory Reset and let your device reboot. 

Note; The Factory Reset option is placed differently on some Android devices. If you can’t find it on About phone, search for “Factory Reset” or “Erase all data” on the Settings app, and it should appear.
