An almost essential setting is the ability to lock your screen by pressing the power key once. It will save plenty of time in the long run.

If this isn’t enabled, then go to Settings – Accessibility – Answering and ending calls.

Then select Pressing the power key.

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.

You can also increase Battery Life by minimizing the numbers of Apps running in the background.

Recent Android versions use a special mode that hides all Android related visuals. The mode is called immersive mode and it essentially means certain Apps have the whole screen available.

Sometimes this can be annoying however and you want to see the time, signal strength or batter indicator.

To temporarily leave immersive mode, simply drag down your notifications screen and the phone will exit immersive mode so you can see other features.

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.

Alternatively if you just want to copy using USB then simply plug a micro USB cable into your phone and it should appear as another drive on your PC.

Some phones do not allow data transfer to PC, to enable this feature go to Settings – Developer Options – Networking, and then tap on USB configuration and change it from ‘Charging’ to ‘MTP’.

Note: Developer Options is not always enabled by default. To enable, go to Settings – System – About Device. Then tap on Build number 7 times to enable this secret option.

Type a word that is not in the dictionary. The word will show up in the suggestion box to the left. Long press on the word and it will save to the dictionary.

When using your Calendar App, you will normally be in Month view. To quickly switch to Year view, you can pinch the screen to zoom out.

This is useful if you want to quickly jump backwards or forwards through a few months at a time.

To go from Year to Month, you can do a reverse pinch.

A useful feature of Android Lollipop is what’s called Screen Pinning. This allows you to lock your phone to one App. Perfect if you have a young child that you don’t want messing with your phone. Or if you want to lend your phone to someone to make a call, but make the call only.

To enable this go to Settings – Security – Screen pinning. Then go to the App you want to Pin and press the Multitask key. Then look at the most recent app and press the blue thumb tack icon in the bottom right corner.

To un-pin an App just press the Multitask key and the back key together.

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.

While in the Camera App, there are two ways to zoom in or out.

First, you can use Volume Up and Down keys.

Secondly, you can pinch your fingers on the screen to zoom in and out.

Android cleverly uses Picasa to sync photos between your account and your phone. Sometimes however, this means that you will get duplicates appearing in your Gallery when they’re not actually on your phone.

To stop this from happening, and so you only see photos on the Phone or SD card, then follow these steps:

Drag down your notification menu from the top and click on the Gear icon to bring up your Settings. Then select Accounts and Google. Then select your Gmail account.

You should see a list of options that are ticked. Scroll down to the one that refers to Picasa and untick that.

Now that’s done we want to remove the thumbnails from your Gallery, so we need to refresh the Gallery. To do that, swipe down and go to Settings again. Then select More – Application Manager. Swipe across to show ALL Apps. Then find the Gallery App and press Clear Data.

This will erase the thumbnails in your Gallery, so don’t panic that your photos have disappeared. Just wait for the Gallery to re-build its index which could take awhile.

But the good news is that your Picasa Albums shouldn’t be there anymore.
