When a single checkmark glows in WhatsApp, it indicates that your message has been successfully sent from your device but has not yet been delivered to the recipient's phone.
When one checkmark glows in WhatsApp, what does it mean - in detail?
When a single checkmark on a message in WhatsApp appears to glow or turn blue, this indicates that the message has been successfully delivered to the recipient's device. This visual cue is designed to provide users with real-time feedback about the status of their messages. It's important to note that while delivery confirmation means the message has reached the recipient's phone, it does not guarantee that the message has been read or seen by the recipient. WhatsApp uses two checkmarks to signify message delivery and a double checkmark (both blue) to confirm that the message has been read by the recipient.
