Step 1: Open Whats App Messenger then Tap on the three Dot menu(Located in the upper right part).
Step 2: Tap on Settings then Tap on ‘Accounts’ and then on ‘Privacy’.
Step 3: Untick the ‘Read Receipts’ option and its Done
Note: If you Turn off Read receipts, you won’t be able to see read receipts or blue ticks from other people when they read your message.
This is also a simple method. Whenever you receive a whats App message it shows a notification on your notification bar. Simply swipe down the notification area from the top of the screen and you can easily read the complete or partial message of the sender and the best thing is this the sender will never get a blue tick because The blue ticks show only when you open the app to read messages.
After getting the message from the sender, simply turn off the mobile data or the Wifi connection and then open the App, after reading the message close WhatsApp and don’t forget to close it from the recent. The sender will never get a blue tick because you read the message from app cache.
