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.
Unlocking can bring many important benefits and can save you a considerable amount of money.

To enable Face Unlock, go into Settings – Security.
Then select Screen lock.
If you use the Face Unlock feature but you’re in a dark room or wearing a hat and scarf, you can bypass the unlock just once.
Simply press the Lock icon on your screen and you can then enter your PIN instead.
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.
Face Unlock allows you to unlock your phone by holding it up to your face. It is highly recommended to use the Improve Face Unlock feature to make the recognition faster and more accurate.
First, ensure you have Face Unlock enabled. Go to Settings – Security – Screen lock. Then choose Face Unlock.
Once that is done go to Settings – Security – Improve face matching. You might have to do this a few times to improve the speed of recognition. It is also a good idea to position the phone at different angles to your head to improve the accuracy.
Note: this may not work on all phones. Check for a software update if it doesn’t work on yours.
To silence the phone when ringing there are two methods:
Either press the Volume Down (or Up) button or if the phone is on a surface facing up, simply flip it over so it is facing down.
To change the screen brightness, start from the Homescreen and press Menu – Settings – Display – Brightness.
Then choose the desired brightness setting. You can also select Automatic brightness to let the phone decide for you.
If you have auto-brightness enabled, you can also press, hold and slide the top notification bar left and right. The brightness will increase and decrease accordingly.
To lock your screen while you are watching videos, simply press the power button.
This will disable the touchscreen buttons while the video is playing, but it won’t turn the screen off like the lock key normally does.
Note, this will only work on video files that you are playing that are stored on your phone. It won’t work for videos played within websites, such as Youtube videos.
If you have Android 4.0, then one neat feature is the ability to clear single notifications.
Simply pull down your notifications bar by swiping your finger from the top of your phone downwards. Then when you see each individual notification, swipe your finger left or right to clear each one.
