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.
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 want to conserve battery life, you can turn off the WiFi while the phone is asleep.
Pull down the notifications screen. Then long press on the WiFi icon. Then press the Menu or More button and select Keep WiFi on during sleep.
To change the homescreen or lock screen wallpaper, press on a blank part of the homescreen. Next, choose Wallpapers.
From here you can use any image in your Gallery as your Wallpaper.
If you want to check how much RAM you have available, drag down your notifications screen and select Settings. Then under Device, select Applications and then Application Manager.
Then swipe from right to left so you see the Running Apps.
At the bottom it should say how much is used and how much is free.
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 homescreen, 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.
To save an image in an email or in the browser, long press on the image and a menu will appear allowing you to save it.
For images inside text messages, you might have to press and hold on the message itself, rather than the image.
The Play store contains thousands of great Apps, but there are time that you want to restrict access to these Apps for whatever reasons. This can easily be done.
First, open the Play Store App and swipe from left to right to see the settings. Then press Settings and Content Filtering.
From here you can chose settings for Low/Medium/High maturity levels. Great for preventing access for young people.
If you want to setup new email accounts, like Yahoo or Hotmail, go to your list of Apps.
Find the Email icon and press on it. A setup wizard will then be launched.
Enter you email address and password into the fields. You can also change the settings after this step.
Once you’re happy with the settings, give your account a Name and you’re done.
