To quickly close Apps, press the Home key

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. Then tap on the Android version option 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.

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.

Android has improved the facial unlock feature by creating a setting whereby you must blink when unlocking your phone. This prevents fraudsters using a photo of yourself and holding it up to the phone.

To activate this feature go to Settings – Personal – Lock screen and security – Screen lock type – Face unlock. Then setup your facial unlocking.

Then once that is done, go to Face unlock again and tick Presence check.

This may not be available on all devices.

Follow this guide if you want to check the data and WiFi usage on your Samsung Galaxy J4.

In this day and age, staying connected is essential. However, whether we like it or not, most mobile data plans put a limit on our data usage each month.

Browsing through Social Media may be fine, but downloading and streaming content can easily eat up on your monthly data allocation.

Reaching your data cap means that you cannot stay online for the rest of the month. Worse, you may be allowed to go online but it also means a huge bill by month’s end.

  1. Go to Settings → Connections → Data Usage
  2. From there, you can set a limit or data cap for a certain time period or billing cycle (a week, month, etc).
  3. You may also press the Menu option and tap “Restrict Background Data Usage.” This option will help you manage your data usage, especially for apps that run in the background (such as Instagram and Messenger). However, this also means that the apps may stop working properly.

To check WiFi usage on the Samsung Galaxy J4, follow these steps:

  1. Go to Settings → Connections → Data Usage
  2. From there, tap on the Menu button (3 vertical dots on the upper-right corner of the screen).
  3. Tap on “Show WiFi” then “Wi-Fi data usage.”

Alternatively, some Android handsets may need to follow these steps below:

  1. Go to Settings → WiFi & Internet → Data Usage
  2. Tap WiFi Data Usage to view WiFi stats.
  3. From this menu, you can also view data/WiFi usage per app.

The methods above generally work for most Android phone devices. Some handsets may have slight variations, you should just look for something similar Connections, Networks, or Data Usage menus.

Huawei users however have to follow a different process. Below is a short guide to check data and WiFi usage for Huawei phone users:

  1. Go to Optimizer → Data Usage
  2. From there, you can view your data usage for the month.
  3. You also have a Smart Data Saver feature. You may turn that on if you want to.
  4. You can also tap on the apps which are shown to be big data consumers and adjust their usage/consumption accordingly.
  5. You may also set a limit by tapping “More Data Settings” then “Monthly Data Limit.”

Normally you can simply insert a SIM card and you will be able to browse the internet using 3G. Sometimes, this must be setup manually however. Before you start, you will need to ask your carrier or Telco for your APN settings.

Once you have those, go to Settings – Connections – Mobile networks – Access Point Names.

From here press the Plus sign at the top right and select New APN. Then fill in the details your carrier gave you. Then press the menu button and press Save.

There is a great app called Moves by a company called Protogeo that makes use of your devices accelerometer to record your movements, whether by walking, cycling or running.

Go to the Play Store and search for Moves.

To change keyboards (if you have additional keyboards installed), you can switch between them by pressing the small keyboard symbol in the top left of your screen. You will need to be in keyboard input mode (i.e. typing something) for this to work.

Alternately you can add and remove key board from settings also.

For that go to Settings – Languages and Input and then tap on Virtual Keyboard.

Now you can add and remove keyboards from this menu.

Note: you need to have more than one keyboard installed for this to work.

If you don’t want to have to unlock your screen every time you take your device out of standby then go to Settings – Personal – Lock screen and security.

Then select Screen lock type and select None.

To soft reset your phone press and hold the Power/Lock button for around 8 to 10 seconds. The phone will restart automatically.

If that doesn’t work, then remove the battery (if it has one). Wait 30 seconds and put the
battery back in. Then press the Power/Lock button to turn the phone on.

Some devices also provide reboot option on pressing Power Button.

While typing emails or notes, you can simply tap the space key twice and the phone will insert a full stop / period.

This option may need to be turned on in the keyboard settings. This can be found in Settings – System – Language and input
