If you see an insufficient storage available error, or find that you’re running low on your phone memory (not to be confused with your SD Card memory), then there are a number of ways to fix this.

This error can be very frustrating as it often means you cannot install new Apps, and some Apps may not even function properly because of this. We hope this guide is as comprehensive as possible, but if you find other methods, then please suggest them in the comments below.

The first step is to determine exactly what is eating up your phone’s storage memory. To do this pull down your notifications menu and select Settings and find Storage. It may take a while to calculate so be patient. From here you can see whether it is your Applications, Pictures, Audio or otherwise, that is causing the problem. Obviously, if it is photos or music, then the first step is to remove some of these (ensuring you do actually want them deleted of course!).

If it is your Apps taking up space, then you have a few options, as follows:

Uninstall Apps – Go to Settings – Applications – Application Manager and swipe to the ALL tab at the top. Then look at the bottom of the screen which shows how much free space you have. Often you will have very little Free memory, which is the cause of the error. From here, press your Menu button and select Sort by size. This will show you which Apps take up the most space and which will make the most impact by removing. Obviously don’t delete things like Gallery (which will remove your photos!), Internet (which is your browser), key Google Apps and so on. However if you have Apps you don’t use anymore, then uninstall them to free up space.

Clear App Cache (with an App) – For this method, you will need to download an App called Clear App Cache. However, this will only work if you can uninstalled enough Apps to free up enough space to install the App itself. Once installed however you can quickly clear the cache of all of your Apps, which should free up some space.

Clear App Cache (manually) – Apps such as Gallery, can sometimes generate a large cache (image thumbnails in this case) which can be cleared to free up memory. First, go to Settings – Applications – Application Manager. Then swipe from right to left until you’re on the ALL screen. Then press the Menu key and Sort by size. Then choose the largest App by pressing on it. Then select Clear Cache. Do this until you’ve cleared as much space as you can.

Dump your log files – This will only work on some devices, however it doesn’t cause any data loss. It simply cleans up your App log files. Go to your phone dialler App and press: *#9900# Then Select delete dumpstate/ logcat and hit OK.

Move Apps to SD Card (if you have one) – Settings – Applications – Application Manager. Flick from right to left until you get to SD Card. Then simply tick which Apps you’d like to move from Phone memory to SD Card memory.

Clear Browser Thumbnails – This one seems to be a bug in some versions of Android and/or some phones, but is a very quick and effective fix. Simply open your stock Android Brower, which is usually found by opening the Internet App. Then at the top right check if you have multiple tabs open. If you do, then swipe them off the screen one by one until you have none left. This can clear up hundreds of cached thumbnails which never clear unless this process is carried out. It has been known to clear several gigabytes of space for users that don’t close their tabs often.

Check folder/file sizes – The last method is great and involves installing an App called DiskUsage from the Play store. Once you install this it will show you which folders are the largest. You can then drill down to find out exactly what is consuming your precious space before deciding to remove the files or folders. You can also integrate the App with File Explorer Apps to easily manage your files. When it comes to removing files and folders it’s sometimes easier to do that by plugging your device into a PC and browsing the folders that way.

By default, your phone will recognise swear words, but insert x’s instead of the word. To change this, go to Settings – System – Language and input – Voice input.

Then you may need to select your voice input system. Then toggle the Block offensive words option.

Android has a feature allowing you to update Applications automatically. This is turned off by default, but you can turn it on.

Open the Play Store App and press the Menu icon in the top left of the App. Then select Settings and Auto-update apps.

From here you can chose to do this over WiFi only or using your Data connection.

If you want to move a widget from one homescreen to another, simply press and hold on the widget. Then drag it to the edge of the screen. The next homescreen will appear. Then, just drag the item to where you would like.

To open a web page in a new tab, find a link on a web page. Then press on it and then choose to open the site in a new tab.

Android has improved the facial unlock feature by creating a setting whereby you must blink when unlocking your phone. This prevents fraudsters using a photo of yourself and holding it up to the phone.

To activate this feature go to Settings – Personal – Lock screen and security – Screen lock type – Face unlock. Then setup your facial unlocking.

Then once that is done, go to Face unlock again and tick Presence check.

This may not be available on all devices.

If you tend to run out of battery power quickly, then you can turn on Power saving mode.

Pull down the notification screen by swiping your finger from the top of the phone. Then select Power Saving. You may need to scroll along the available icons.

To change the settings, then pull down the notification screen again, press the Gear icon at the top. Then under System select Battery and then Power saving mode to change the options.

If you call someone regularly this can be useful as you will have a shortcut to them handily placed on your homescreen.

To bookmark a Contact on your Home Screen, then first go into your Contacts App.

Find the Contact you want to add to the Home Screen and press on them.

Then press More or the Menu key and select Add shortcut to home.

Then go to your Home Screens, find the Contact you’ve just added. Press, hold and drag to another position.

There are a number of solutions to this error. Go through the following steps:

Go to Settings – Applications – Application manager. Then swipe right to left to go to All (along the top). Then find the App called Media Storage. Click on that and select Force Close. Then select Clear Data. (warning: this will delete the cache for your media player so you may lose things such as recently played, most played etc. But you will not lose your music).

Next, go back to list of Apps and find Music Player. Again, press Force Close and then Clear Data.

Once that’s done, go to the Play Store and download an App called Re Scan Media and run it. Wait 5 minutes for the device to re-scan your media.

If you still cannot play your music, then try turning your phone off and removing your SDCard / memory card (if you have one). Then turn the phone on without the card. Then turn it off again and reinsert the card. Finally turn it on again with the card back in.

If you still can’t play music, then some users have said that there may be a conflict with the Twitter App. Try uninstalling this and see if the error persists.

Sometimes you will want to prevent your device fro, displaying or indexing folders on your Phone storage or USB storage.

To do this, simply rename the folder and place a . (full top / period) before the file or folder name.

This can be done through the Files App or by plugging your device in to your computer and renaming it there.
