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.

If you are running low on phone storage memory, you can look for your largest applications to uninstall.

Go to Settings – Applications – Application manager.

From here you can see which applications are taking up the most memory and uninstall them.

There is no need to be stuck with the standard Android keyboard, which isn’t always great for typing quickly.

Go to the Play Store and search for ‘Keyboard’ to see some great alternatives, many of which are more accurate and make typing much easier.

One of the very best is SwiftKey. They provide a free trial, but once the trial is over it is well worth the small amount of money they charge. It can increase your typing rates massively.

Another good one is GoKeyboard.

If you see a warning saying the keyboard will collect all information (including credit cards) just ignore this. This is just a security feature that Android shows for every third-party keyboard that you install.

If you see the following error:
Unfortunately, the process android.process.acore has stopped

Then follow these steps:
1.First, go to your phone’s main Settings and select App Manager.

2. Then, tap on the menu button usually at the top right left.

3. Select Reset App Preferences.

Alternatively, you can also disable all apps and enable them again one by one until you find the app that has been causing the error.

If none of the above works, you can do a Factory Reset or reboot, instead. Be warned you may lose all of your data when performing a Factory reset.

Normally you can simply insert a SIM card and you will be able to browse the internet using 3G. Sometimes, this must be setup manually however.

Before you start, you will need to ask your carrier or Telco for your APN settings.

Once you have those, go to Settings – Mobile networks – Access Point Names.

From here press Add or the Plus sign at the top right and select New APN.

Then fill in the details your carrier gave you. Then press the menu button and press Save.

Instead of the simple swipe gesture to unlock your phone, you can set a custom one which can be extremely difficult for a thief to guess.

From your home screen, go to Settings – Personal – Lock screen and security – Screen lock type and choose Pattern.

It is also a good idea to untick Use visible pattern. Then if someone is watching over your shoulder while you entering your pattern, it will be harder for them to remember the pattern.

If you have forgotten your unlock pattern, then after 5 unsuccessful tries a button will appear saying ‘Forgot pattern’.

Press this and you will be asked to enter your Gmail username/password. The phone will then ask for a new unlock pattern.

If you don’t have a Gmail account, then you will have to either call your carrier or factory reset your phone.

If you want to find your phone’s WiFi MAC address (for improved WiFi security), then go to Settings – System – About device – Status.

Then scroll down until you see WiFi MAC Address. The address should be a series of Hex numbers and letters.

Android has a way to display your owner info (i.e. name, phone, email or a personalised message) on your lock screen. Perfect if you have lost or misplaced your device.

To enable this go to Settings – Personal – Lock screen and security – Info and app shortcuts – Owner information.

Here you can enter any information you want, such as your name or email address.

Hopefully if your phone is lost, then the finder can use this information to get in contact with you.

If you would like to unmount your SD card for whatever reason, then drag down your notifications menu from the top of the screen and press the Settings icon.

Then find Storage – SD card – Unmount SD card.

The phone has the ability to send quick response text messages if your phone is ringing but you can’t answer it.

To change these, go to your Dialler App and press the Menu or More button.

Then select Settings – Call blocking – Call-reject messages.

From here you can add or edit your reject messages.
