The first time I saw the “insufficient storage available” message I totally panicked.

I was in the middle of traveling and had taken a lot of photos that day. I was halfway up the top of a mountain in a gondola and needed to take pictures of some once-in-a-lifetime views. I tried to take a picture and saw this terrifying message: “Insufficient Storage Available”.

Immediately, I uninstalled every app I didn’t really need. I deleted old pictures and videos that I had already backed up. It was barely enough to get me through the day.

Anyways, if you want to avoid the insufficient storage available error message, then I’m going to help you out. Here’s a step by step guide to avoid this message and fix your storage space issues.

Why does this Error Occur?

You often see this error when you’re trying to update or install a downloaded app on your Android device.

Obviously, on some devices, this legitimately means you have insufficient storage space available, and that you need to delete stuff to make more room.

In other cases, however, this message will pop up when you know that you have enough storage space. You might have recently moved large amounts of media from the Android device’s physical storage to a microSD card, for example, and the cache wasn’t properly erased.

How to Clear your Cache

If your error is occurring because of a cache issue, then you need to clear your cache.

There are two ways to do this:

1) Install a Cache Cleaning App: If you have more than about 2MB of room, then you should be able to fit a cache cleaning app onto your device.

Clean Cache – Optimize is one popular free cleaner with over 200,000 Google Play Store downloads. App Cache Cleaner is another popular one with 190,000+ downloads. Both do the same basic job and wipe out cache data from your apps.

2) Clear your Cache Manually: If your data storage problem is really bad, then you’ll need to clear your cache manually (you won’t have room to install a cache cleaner).

Fortunately, that’s not really as hard as it sounds. Just open your Application Manager (under Settings) and navigate to each individual app, clearing your cache along the way.

If you feel comfortable clearing all your cached data, then certain devices also allow you to clear all cache data at once.

On the Galaxy S6, for example, you can go to Settings > Storage > Cached data > Delete to wipe out all cached data from all your apps.

If you don’t want to wipe out all app cache data, then you’ll find that some of the bad offenders are Facebook, Chrome, and Google Maps. These can often hide hundreds of megabytes of data in their caches.

Note: Clearing out your cache doesn’t have any noticeable effect on your usage of the app. You don’t even have to login again.

What to Do If You Have No Storage Space

Sometimes, you’ll see the “Insufficient Storage Available” warning because you legitimately have no storage space.

If that’s the case, then there are a number of tips you can do to free up storage space:

-Uninstall old apps

-Clear out old photos and videos and upload them to cloud storage services

-Clear your cache manually

-Perform a factory reset

-Add a microSD card to your device (if it supports microSD) and transfer data to that card

-Root your device to clear blocked data that you cannot normally access on a non-rooted device

Rooting is the best long-term solution, but uninstalling apps and clearing out old photos can work pretty well too.
