No matter how much storage we have in mobile phone but every now and then we all face insufficient storage issues. If you will check storage status in your phone, you will see that you have plenty of storage space available… way too much for a small app… but still Android will keep on popping the message Can’t install app: Insufficient storage available.

Can this annoying problem be fixed?  Well, yes! There are a few things that you need to know and then you can try a few methods to fix this problem. Let’s find out how to solve “Cant install app: Insufficient storage available”.

Reason Behind Android Insufficient Storage Issue

Android, the most popular mobile operating system, uses storage in the following ways:

  • Storage required by the system itself (i.e. Android)
  • Storage required for apps
  • Storage required for app data files
  • Storage required for app cache

We all know what Android apps are. These apps store data important for their functioning in files that are called data files.

App cache is created for faster functioning of your apps and to minimize dependence on mobile Internet connection.

Can’t Install App. Insufficient Storage Available in Android

One of the most annoying error messages in Android

The total space occupied by app cache could be really big but the problem with Android is that it does not count app cache size while reporting the storage statistics. Android counts cache storage as free space — but in reality app cache space is not free. Your phone may tell you that you have 10GB free space but still you may not be able to to install a small app as probably 9.99GB of that “free” space would be occupied by app cache! And, as a result, you will get the most irritating Cant install app: Insufficient storage available error message.

How to Fix Cant install app: Insufficient storage available Error?

Method 1

First of all you should clear the app cache of your phone. You can begin with clearing cache of the biggest apps installed on your phone.

  1. Go to Settings > Apps > Applications
  2. Go to the list of downloaded apps
  3. Tap on menu button and select “Sort by size”. This will sort the app list according to the space they are occupying.
  4. Now tap on the first (i.e. biggest) app. You will see the following buttons:
    1. Force stop
    2. Uninstall
    3. Clear data
    4. Clear cache
  5. Tap on Clear cache button. Android may ask you for confirmation. Confirm and clear the cache.

  6. Repeat this process for a few big apps

Method 2

The second thing you can try is to move certain apps from phone’s internal storage to the external storage (like SD card). Please note that not all apps can be moved to external storage. From the sorted app list (as discussed above), open apps one-by-one from top… and see where you get the Move to SD card button enabled. This button will be enabled for the apps that can be moved to SD card.

Usually SD cards have bigger storage than phone’s internal memory. So, it is a good idea to move all the apps that can be moved to SD card. This will save you space in the internal memory.

Method 3

Some people love downloading all sorts of apps from Play Store. We download many apps just to try them but we don’t care to remove them if we don’t find them useful.

We are sure that you have already tried to remove unnecessary apps. In case you haven’t, it is recommended that you take a look at the list of installed apps and see which of those you can live without. Removing unnecessary apps is an obvious way of freeing storage space.

In the same vein, you may also consider removing unwanted videos, audio files and photos.

Avoiding “Cant install app: Insufficient storage available” Android Error

If you often get insufficient space available error, it would be wise to install a cache cleaner app while you can. You can install any of the following apps:

  • App Cache Cleaner – 1Tap Clean
  • Clean Master

These apps can quickly wipe off cache files from your phone. So the next time you will run into insufficient storage problem, you will just need to open the already installed cache cleaner and delete all the cache to free up the space.

    What happens if I tap on 1) Force stop and 2) Clear data buttons of Apps like Google Play services, Google App, Chrome, Google Keyboard, Google Photos etc. which are already factory installed in the mobile phone? Will this action harm my phone in any way?

    • Lalit Kumar says:

      No, in some cases your phone will not allow you to Force Stop and Clear Data of the factory installed apps. But if it allows you to do so, you can go ahead. It does not harm your phone. Clear Data option only clears the data cache — which automatically gets rebuilt after sometime.
