There are a number of ways to speed up your phone. The following list are tried and trusted techniques:

Firstly, uninstall apps that you don’t use. Over time your device can get cluttered as some Apps are designed to always run in the background. If you don’t use an App very often, then uninstall it to free up memory and CPU resource.

Use Static wallpapers instead of Live ones. Live wallpapers often consume processing power and memory. Unless you really need them, uninstall them.

Use home screen widgets sparingly. These often slow down the phone and use up memory and CPU resources. If you don’t really need the widget, then uninstall it.

Install a great App called DU Speed Booster and DU Battery Booster. These Apps are prefect to run when your phone starts to slow down, you’re running out of memory or you want your battery to last for a few more minutes or hours.

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.

To change the backlight screen timeout, drag down your notifications screen and press Settings.

Then select Display.

Then under Screen timeout you can set the screen time out duration.

You can also tell the phone screen to always stay lit when it is plugged in via USB:

Go to Settings – System – Developer Options. Then check Stay Awake.

Note: Developer Options is not always enabled by default. To enable, go to:

Settings – System – About Device – Software info . Then tap on Build number 7 times to enable this secret option.

To enable or disable the vibrate function when you receive text messages, go to the Messaging App and press the Settings icon in the top right.

Then select Notifications – Vibrate when sound plays.

To enable or disable vibration for incoming phone calls, then go to your main Settings, then Sounds and vibrations, then Vibrate when ringing.

If you find you’re forgotten your backup password, try the following using Google’s Android Device Manager:

On a computer or in a mobile browser, go to www.google.com/android/devicemanager.

Sign in to the Google Account that you previously added to your device.

If you have more than one device, select the arrow next to the name of the device you’re locked out of. Android Device Manager will show you the approximate location of your device on a map.

Select Lock.

Enter a temporary password for your device, then click Lock again.

On your device, enter the temporary password on the lock screen.

Drag down your notifications bar and select Settings – Lock screen and security.

Enter your temporary password again, then follow the prompts to reset your device.

If you see the following errors:
Resting robot
Exclamation point (for rooted phones)
No command

This indicates that your phone is in Android Recovery mode and often appear when you try to recover or reboot.

To fix this, follow these steps:

1. Once any of the three appears, press and hold your phone’s volume up button for 10-15 seconds.

2. Next, without letting go of the volume up button, press and release the power button once. It will display a menu.

3. Navigate around the menu using the volume button.

4. Select Reboot System Now and your phone should be rebooting

Alternatively, you can do the following:

1. When any of the three appears, press and hold the power button for 2-3 seconds.

2. Then, without letting go of the power button, press and release the volume up button, once. It will display the same menu.

3. Select Reboot System Now and your phone should reboot.

If Reboot System Now doesn’t work try updating first.

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.

A handy feature of Android is to quickly clear your 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. You can do this with your Apps too – press and hold the multitasking button. Then swipe left or right to close Apps.

To store a phone number that you have received in an email, hold down on the number and you will be given the option to call, send an SMS or add the number to your contacts

If you want to check how much RAM / Memory you have available, drag down your notifications screen and select Settings.

Then under Device Maintenance, select Memory.

From this screen you should also be able to see which Apps are currently running and taking memory.

You can also see which are taking up valuable CPU time. Useful if you think some Apps are draining your battery.

Depending on how your phone is set up, sometimes you will see lag when swiping between home screens or when generally using your phone. There are a number of things you can try to fix this, as follows:

First, try restarting your phone. This will fix many problems.

If that doesn’t work, then remove any Widgets that pull data to the phone, such as Twitter, Weather widgets etc.

If you have Live wallpapers turned on, then try turning them off long pressing on a blank area of the home screens and changing to a different Wallpaper.

Sometimes the problem can be with the phone or operators skin or launcher, so try going to the Play Store and downloading a third party launcher such as Nova launcher or Go LauncherEx. Note: you will need to re-create your home screen shortcuts, but they are both great launchers.

Another tip is to always press the Back key instead of the Home key when leaving Apps. The Back key will often close the App properly, while the Home key can leave it running in the background.

Lastly, there is a great app called DU Speed Booster which can help close Apps that are running in the background and optimise your phone’s memory.
