If you don’t want to hear the shutter sound when you take photos, then there are a few things you can try.

Firstly, some countries have laws to force the phone to play these sounds. Assuming you’re not in one of these countries, then the first thing you can try is to go to the Camera App – Settings – Shutter Sound – Off.

If that doesn’t work, then you can try turning the volume of the phone down or put it in silent mode when taking photos.

The last option is to Root your phone. If you don’t know what that means, then it’s best not to attempt it unless you have thoroughly read about the process. Once Rooted, go to this folder on your phone: /system/media/audio/ui and rename the camerashutter and/or cameraclick OGG files to something else.

Alternatively, on a rooted phone you can use a Root Browser, to edit /system/csc/feature.xml and set the option to TRUE. Then you should be able to go to Camera App – Settings – Shutter Sound – Off.

Sometimes you might want to let someone borrow your phone, but you don’t want them messing with your settings or using some of your Apps.

Fortunately there is now a mode called Guest Mode. It may not be available on all models or phones but it can be accessed by swiping two fingers down from the top of the phone. Then select the User icon at the top right of the phone. Then select Add Guest.

To exit guest mode, just repeat the above steps but select Remove Guest instead.

To add a widget, simply long press on a blank part of one of your homescreens. Then select Widget. Scroll through the list of available widgets and choose one. It will be placed on your homescreen and you can move it around as you desire.

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 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.

Android now comes with some great battery management built into the OS.

Pull down your notifications screen and select Settings. Then go to Battery and you will see some useful stats such as the time remaining. There are also two other options: Power saving mode and Ultra power saving mode. Select one of these to really make your phone last the distance.

Be warned that these can limit your device quite considerably.

Android manages Apps very well and some Apps do not have the option to close them specifically. Normally the App will stay running in the background and only close when many other Apps have been opened.

If you do want to close or terminate an App, then press and hold the Multitasking key on your phone. On some devices you may need to long press the Home key.

Then you can swipe the Apps off the screen to close them.

If you want to resize your homescreen widgets, then press and hold on a widget for 2 seconds. If the widget is resizable, then an outline will appear around the widget. Simply drag the sides to resize the widget.

If the outline doesn’t appear or you can’t drag the lines, then the widget is a fixed sized widget.

To enable / disable your notification light, go to Settings – Device – Sounds and notifications – LED indicator.

From here you can choose various options.

This may not be available on all models. An alternative however is to download NoLED from the Play Store, which has many options for incoming notifications.

When taking photos or videos, tap the screen where you want to focus on. The phone will automatically adjust the settings to improve the image or video
