Learn Common Mobile Applications for Everyday Use

This page is created to help you understand and use common mobile applications we rely on every day. Whether it’s scanning QR codes, joining WhatsApp groups, or managing and scheduling Google Meet sessions, this guide will make things simple and easy for you.

QR Codes

Nowadays, QR codes are everywhere! They are widely used for tasks like money transactions, sending invitations, joining WhatsApp groups without needing a direct link, filling out forms, or sharing links with others without saving their contact numbers. QR codes have many applications, but here we will focus on clearing up the common confusions you might face while using them.

Common Mistakes When Using QR Codes

People often get confused about which app or scanner to use for different types of QR codes. For example, someone might try to scan a form’s QR code with a payment app like Google Pay or PhonePe, or use the wrong app to join a WhatsApp group. To avoid such confusion, here’s a simple guide on when to use which scanner:

For Joining WhatsApp Groups: Use the camera icon in your WhatsApp app—you don’t need any additional apps or scanners. Simply open WhatsApp, tap on the camera icon, and scan the QR code. Once scanned, you’ll see a message asking if you want to join the WhatsApp group. Just click "Join," and you’re all set!

• 

  Click on the camera icon in your WhatsApp

• 

  Place the camera towards the QR code & Click on the Join Group option

• 

  You’ll be joined to the group instantly

 Note: If, after placing the camera on the QR code, the "Join Group" option doesn’t pop up, try capturing the photo in WhatsApp itself. This should take you to the group. If it still doesn’t work, check your internet connection and try again.

For Accessing Invitations or Filling Out Forms: By now, we know how to join a WhatsApp group using a QR code invitation. But what about scanning other invitation links or forms? 🤔 The best option is Google Lens 🔍, which can scan and open links from QR codes. Google Lens comes pre-installed on most smartphones, so you don’t need to download any extra apps! Some phones also have a built-in QR scanner in the camera app, making it even easier to scan and access links effortlessly.

Let's see how to use Google Lens 🔍 to scan QR codes!

To open Google Lens, you have two options:

1️⃣ Using Google Search: Google Lens is built into the Google Search app, which comes by default on all Android phones. Simply open Google Search and tap the Lens icon to start scanning.

2️⃣ Using the Camera Shortcut: Many phones (especially those running Android 13 and above) have a Google Lens shortcut in the camera app. However, some Android 13 devices may not have this feature.

You can choose either of these options to scan a QR code. Check out the images below for a step-by-step guide!
