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.

Checking Available RAM and CPU utilization on your Asus Zenfone 4 Pro is very helpful if you are thinking about removing more Apps.

Looking at which Apps drain your RAM, CPU time, and battery will help you decide which of them should be removed from your phone.

To do this, just follow the simple steps below:

  1. Go to your phone settings. You can do this by swiping down the home screen to reveal the notification bar. From there, tap on the gear icon to open Settings.
  2. Look for Device Maintenance → Memory
  3. Alternately, you can also tap on “Data Usage,” then scroll down to see which apps are taking up CPU power.
  4. You may also look for “Smart Manager.” You will see the status of your RAM and Storage in this area. If you tap RAM, you will see a list of apps that are taking up much of your RAM.
  5. For Huawei users, you can look for “Storage” under Settings.

All methods from 2 to 4 can be accessed on the Phone Settings alone. There are certain variations, depending on your phone or unit.

This section should also show what is taking up valuable CPU time. Useful if you think some Apps are draining your battery.

The phone has the ability to send quick response text messages if your phone is ringing but you can’t answer it.

To change these, go to your Text Message (SMS) App and press the Menu or More button.

Then select Settings – Quick responses.

From here you can add or edit your reject messages.

There are a number of ways, as below. The first two of these may be disabled on some networks/carriers or Android versions however.

1) Go to Settings – Apps. Then scroll down to Contacts Storage – Clear Data. This option may not be available on all models.

2) Go to Contacts. Then hold and press on a contact. Then choose the All option at the top of the screen and select Delete. .

3) Go to Settings – Cloud and accounts – Accounts.

Then scroll down and select Google.

Next, change the slider so that Sync Contacts is disabled.

Then go to Gmail and delete all of your Contacts from there. Then re-sync your phone.

4) Download an App called ‘Delete All Contacts’ and use that as a last resort.

The methods above will delete contacts from the Phone only, not the SIM card.

If you are not happy with your notification light, then you can change and tweak it. Go to the Play Store and download an App called Light Flow.

You might need to enable the notification light before the App works. Go to Settings – Display – LED Indicator.

If you have decided to ditch your iPhone in favour of Android, then there is a simple way to take your iTunes music, playlists and album art with you.

Simply go the Android Marketplace and download a Free App called iSyncr.

You will also need the computer version of the software, so go to http://www.jrtstudio.com and download it from there.

Then, when that is done, turn your phone into a USB storage device (this will vary from device to device, but instructions are on the website).

Once your device is connected to your computer, open the computer version of the software and select your device from the Easy Phone Tunes list. Then follow the instructions to Sync your media.

There is a hidden Android Easter egg on the phone that Google has built into your device.

Go to Settings. Then scroll down to About device or About phone.

Then select Software info and find Android version.

Press this 5 times.

Once you see something on the screen, you can then rub the screen with your finger to produce another surprise. If rubbing doesn’t work then try tapping with your finger. A combination of the above should work. If not, then try different things. That’s the fun of the Easter egg.

By the way don’t expect to see an actual Easter Egg. That is just the name given to things hidden inside software or operating systems.

To add a widget, simply long press on a blank part of one of your home screens.

Then select Widget.

Scroll through the list of available widgets and choose one.

It will be placed on your home screen and you can move it around as you desire.

While using the standard Android Video App, you can lock the your screen while watching videos by pressing 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 and using the native Video App. It won’t work for videos played within websites, such as YouTube videos or other Apps such as MX Player, which have their own lock screen settings.

A great new feature is dual shot which lets you take a picture of someone else with the rear camera, while simultaneously taking a picture of yourself with the front facing camera. The problem is this feature isn’t obvious to find as it isn’t included in the list of camera Modes.

To find it open your Camera App and you will see three icons in the top right corner. Dual shot is the middle icon of these. Press that and you both cameras will activate allowing you to shoot away.
