Here are 7 useful hidden features in WhatsApp that can seriously level up your chatting experience:

💡 1. Hide "Last Seen" from Specific People

Tap "My Contacts Except..." and select who you want to hide from

🕵��♂️ 2. View Message Details (When Delivered & Read)

Tap info (i) on top (iPhone) or three dots > Info (Android)

🎧 3. Listen to Voice Notes Privately
Why it's useful: Listen to voice messages discreetly even in public.

How to do it:

Play the voice note and quickly put the phone to your ear – the proximity sensor will switch audio to the earpiece.

Why it's useful: Keep essential chats (like work or family) always at the top.

How to do it:

Long-press the chat > Tap the pin icon (📌)

Close WhatsApp before turning off Airplane Mode

OR, disable read receipts via Settings > Privacy > Read Receipts (note: this disables it both ways)
