It is best to avoid task killers such as Advanced Task Killer. Android is designed to automatically pre-load certain applications, even if you don’t load them yourself. If it starts to run low on memory, it will smartly unload the oldest running apps automatically.

Manually killing tasks will only mean they get loaded in memory again. Task killers can make the phone slow, laggy, or drain battery life more quickly.

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 press the Menu icon in the top left of the App. Then select Settings and Content Filtering.

From here you can chose settings for Low/Medium/High maturity levels. Great for preventing access for young people.

There are a couple of ways to bring up one of your contacts.

First, while in your Contacts App, simply start typing in the search bar at the top of the screen.

Or else a quicker method is to use the Google Search widget (installed by long pressing on a vacant part of your homescreen and installing the widget) and start typing the name of the contact you want to dial. This will quickly filter the correct contact.

To copy files between your phone and PC, go to the Android Play Market and download an app called Air Droid.

This is an extremely useful App that connects your phone to your PC wirelessly, allowing you to move files and many, many other things.

Here are the top 5 tips to make your phone run faster:

1) Use only essential widgets on your homescreen – each widget consumes memory and processing power which can slow your down your phone.

2) Uninstall apps that you don’t use – after awhile your phone can get cluttered as some Apps are designed to always run in the background. If you rarely use an App, then uninstall it to free up memory and CPU resource.

3) Install Apps to your phone memory – if you have an SDCard, always install Apps to the phone memory, which can be accessed faster. If you have Apps on the SDCard, then move them back to the phone memory with an App called Move2SD available from the Play Market.

4) Use Static rather than Live wallpapers – Live wallpapers consume processing power and memory. Unless you really must have them, uninstall them.

5) Kill tasks occasionally – Some Apps will run in the background indefinitely unless you kill them. Most of them won’t cause a problem, but it pays to check your running tasks from time to time. Hold down your Home key and check the Task Manager.

One last thing: Don’t use Task Killers. Android manages tasks very well and Task Killers just make your phone unstable and can slow it down further.

To add an email or phone number to your contacts from a text message, you can long-press on the email / phone number. Then select Add to contacts

Your phone comes with a handy widget which lets you kill all running tasks. This is great if you want to quickly free up some memory.

To use the widget, press and hold for 2 seconds on a blank part of any homescreen. Then find the Active Apps Manager widget and install it.

Once that is done, press the widget and it will show you all currently running Apps. Press End all to close all running Apps.

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.

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’s 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 – More – 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 – 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 – More – 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 have forgotten your custom unlock pattern, then don’t panic.

After 5 unsuccessful tries a button should 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 might have to either call your carrier or factory reset your phone.
