You probably use WhatsApp more than any other app on your phone. Chatting, calling, sending photos — it's how Pakistan stays connected. But even after using it for years, most people have no idea about some incredibly useful features hiding right inside the app. No extra apps needed. Let's go through them.
1. How to Lock Private Chats With Fingerprint
Got chats you don't want anyone to see when they borrow your phone? WhatsApp lets you lock specific conversations behind your fingerprint or face unlock.
How to do it:
- Open the chat you want to lock
- Tap the contact name at the top
- Tap Chat Lock → Turn it ON
Your locked chats disappear from the main chat list. To find them, swipe down on the Chats screen — you'll see a "Locked chats" folder.
Bonus trick: You can set a Secret Code (different from your phone password) to open locked chats. Go to Locked chats → Settings → Secret Code. Now, even if someone knows your phone password, they still can't open your private chats. You can learn more about this feature on WhatsApp's official help center.
2. How to Send HD Photos Without Losing Quality
Normally, WhatsApp compresses your photos,s and they look blurry on the other end. Most people don't know you can now send full HD photos — and even set it as the default permanently.
How to do it:
- Open a chat → Tap the attachment (📎) icon → Select a photo
- Before sending, tap "HD" at the top of the screen
- Choose HD Quality → Send
| Quality | File Size | When to Use |
|---|---|---|
| Standard (default) | ~100 KB | Quick sharing saves data |
| HD Quality | ~1–3 MB | Important photos, documents, memories |
Want to set HD as the default permanently? We wrote a full step-by-step guide on this — check out How to Send Quality Photos on WhatsApp (2026 Update) for the complete method, including the document trick for zero compression.
3. How to Edit a Message After Sending It
Sent a message with a typo or wrong info? You don't need to delete it anymore — WhatsApp now lets you edit sent messages.
How to do it:
- Long-press the message you want to edit
- Tap Edit (pencil icon)
- Make your changes → Tap the green checkmark
| Rule | Detail |
|---|---|
| Time limit | 15 minutes after sending |
| Visibility | Shows "Edited" label to the receiver |
| Works in | Individual chats and group chats |
4. How to Stop WhatsApp From Filling Your Storage
WhatsApp automatically downloads every photo, video, and GIF sent to you — including all those "Good Morning" images from family groups. This is the #1 reason your phone storage fills up.
How to stop it:
- Open WhatsApp → Settings → Storage and Data
- Under Media auto-download, change each option:
| Setting | Change To |
|---|---|
| When using mobile data | ❌ Uncheck all |
| When connected to Wi-Fi | ✅ Photos only (optional) |
| When roaming | ❌ Uncheck all |
Now, the media only downloads when you tap on it manually. No more auto-junk filling your phone.
Already full? Go to Settings → Storage and Data → Manage Storage to find and delete the biggest files and forwarded messages.
5. How to Message Yourself on WhatsApp
Need to save a quick note, link, or file? You don't need a separate app — just message yourself.
How to do it: Open WhatsApp → Tap new chat icon → You'll see "You" at the top → Tap it.
Now you have a personal chat for saving links, forwarding important messages, sending files to your laptop via WhatsApp Web, or keeping quick reminders.
6. How to Silence Unknown and Spam Callers
Getting random WhatsApp calls from unknown numbers? Spam calls are a huge problem in Pakistan. WhatsApp can silence all of them automatically.
How to do it: Settings → Privacy → Calls → Turn ON "Silence unknown callers"
| What Happens | Detail |
|---|---|
| Unknown callers | Silenced — your phone won't ring |
| Saved contacts | Ring normally as usual |
| Missed calls | Still shows in your call log |
This doesn't block anyone — it just stops your phone from ringing for unknown numbers. If you're also getting spam on your regular phone line, read our guide on How to Block Spam Calls in Pakistan Using Free PTA Codes for more protection.
7. How to Hide "Last Seen" and "Online" Status
Don't want people knowing when you were last online? You can hide both.
How to do it: Settings → Privacy → Last Seen and Online
| Setting | Options |
|---|---|
| Last Seen | Everyone / My Contacts / My Contacts Except... / Nobody |
| Online status | Everyone / Same as Last Seen |
Keep in mind: If you hide your Last Seen from someone, you also can't see theirs. It works both ways.
8. How to Use Two WhatsApp Accounts on One Phone
If you have two SIM cards — very common in Pakistan (Jazz + Zong, for example) — you can now use both numbers on WhatsApp without any cloning app.
How to do it:
- Open WhatsApp → Settings (⋮ top-right)
- Tap your profile name at the top
- Tap Add Account → Set up with your second number
Both accounts work independently with separate chats and contacts. This feature works on most Android phones running the latest WhatsApp version from Google Play.
9. How to Format Text in WhatsApp (Bold, Italic, Strikethrough)
You can style your WhatsApp text without any extra app — just wrap your words in simple symbols:
| What You Want | Type This | Result |
|---|---|---|
| Bold | *your text* | your text |
| Italic | _your text_ | your text |
| ~your text~ | ||
Monospace |
``` your text``` | your text |
Great for making important points stand out in busy group chats.
10. How to Create Polls in WhatsApp
Need a group decision? Instead of everyone replying separately, create a poll. It works in both individual and group chats.
How to do it:
- Open a chat → Tap attachment (📎) icon
- Select Poll
- Type your question + add up to 12 options → Send
Everyone votes, and you see results in real time. Perfect for picking restaurants, meeting times, or trip plans. Meta announced this feature along with several other updates on the official WhatsApp blog.

WhatsApp keeps adding features, but most of them are buried in settings menus nobody opens. Now you know 10things that can make your daily chats safer, cleaner, and more useful. Start with Chat Lock and turning off auto-download — those two alone make a big difference.
