Peterderosser Does anybody know if it's possible to see a message on whatsapp turn unread after it was read before that?
You can mark a conversation as unread in WhatsApp.
- Open the list of your conversations on WhatsApp
- Long press the conversation you want to mark as unread
- Tap the 3 dots in top right corner to open the context menu
- Tap "mark as unread" from the context menu.
Peterderosser And it also turned blue while the person last checked whatsapp before the message was even sent.
If the check marks next to the message have turned blue then the contact has read the message. If the check marks turn blue immediately despite WhatsApp saying that the contact was online only a while ago, I would suspect that the "last seen" time shown next to the contact is not always accurate.
