How to FIX When Telegram Cannot Scan QR Code

Here are the seven (7) methods you can use to rectify the issue;

---

Method 1: Clear Camera Cache and Re-try

Why Clearing Cache Works

You see, cache is like your device’s short-term memory. It stores data temporarily to make processes quicker.

But sometimes, too much data accumulates, causing things to go awry. In the case of Telegram’s QR code scanner, a cluttered cache could lead to scanning issues.

To clear your camera’s cache:

• Go to Settings on your device.
• Navigate to Apps & Notifications.
• Locate the Camera app.
• Tap on Storage & Cache.
• Hit Clear Cache.

Method 2: Expired QR Code

Let’s talk about the elephant in the room—expired QR codes. Just like that carton of milk in your fridge, QR codes have a shelf life too.

Why QR Codes Expire

QR codes can expire for a bunch of reasons. Maybe it’s a temporary code for a time-sensitive task, or perhaps the server it’s linked to has moved on to greener pastures.

Whatever the reason, an expired QR code is as useful as a screen door on a submarine.

What to Do When Your QR Code Is Expired

So you’ve got an expired code, now what? First, try regenerating the code from the source. Whether it’s linking a device or sharing contact info, go back to square one and create a fresh QR code.

Method 3: Adjust Camera Focus Manually

The problem could be as simple as a blurry focus. Think of your camera like a person squinting to read fine print—sometimes it needs a little help to see clearly.

The Science Behind Camera Focus

When a camera focuses, it’s aligning the lens to make a subject clear. Sometimes, the auto-focus feature gets a bit lazy or distracted. That’s when you have to step in and say, “Hey, focus!”

To manually adjust your camera focus:

• Open your Camera App.
• Tap the screen where the QR code is to force the camera to refocus.
• Hold the phone steady—no one can focus while shaking, not even your camera.

Method 4: Tinker with App Permissions

Safety Concerns When Altering Permissions

First things first: altering app permissions isn’t something to do willy-nilly. You’re basically telling your phone what an app can and can’t access, so tread carefully.

To alter Telegram’s app permissions:

• Go to Settings on your smartphone.
• Scroll down to Apps & Notifications.
• Find Telegram and tap on it.
• Hit Permissions.
• Find the Camera permission and enable it.

Method 5: Use Telegram Web to Scan QR Code

Alright, let’s flip the script here. What if I told you that you could use Telegram’s web version actually to scan that stubborn QR code?

Telegram Web’s Hidden Talent

Most folks use Telegram Web as a fallback for messaging when their mobile app isn’t working. But Telegram Web also has a QR code scanner built right in!

It’s versatile like that Swiss Army knife you keep forgetting you have.

Here’s how you scan a QR code using Telegram Web:

• Open your Telegram Web on a different device.
• Go to settings, and look for the “Devices” or “Active Sessions” option.
• You’ll see a camera icon or a ‘Scan QR Code’ option—click on that.
• Point it at the QR code you want to scan on your original device.

Method 6: Scan Using an External App

The Why and How of External Scanning

Using an external app to scan a QR code is a workaround, but if it gets the job done, why not? You’ll basically scan the QR code with this other app and then manually enter the data into Telegram.

To do this, you’ll need to:

• Download a trusted QR code scanning app from your app store.
• Open the app and scan the QR code.
• Copy the resulting data or link.
• Manually enter this into Telegram.

Method 7: Run a Device Compatibility Test

Sometimes the issue might not be with Telegram or the QR code, but rather with your device.

Understanding Compatibility

Compatibility in tech terms is like a love match. Your device and the Telegram app have to get along well enough for all functionalities to work smoothly.

So, let’s make sure your device isn’t the one causing trouble in this relationship.

Here’s how to run a quick compatibility check:

• Visit Telegram’s official website to see the list of supported devices.
• Check your device’s system settings to see if it meets the minimum requirements.
• Update your device’s software, if necessary.
