How does Android confirm that he has read the text message?

Confirm whether the short message has been read by the other party on the Android phone by the following methods:

1. View the read/unread indicator: Most communication applications will display the read indicator when the message has been read, such as the "opposite party has read" sign next to the message or the outline of the opposite party's avatar becomes solid.

2. Check the timestamp: By checking the timestamp of the message, if it is displayed within a short time after you send the message, it may indicate that the other party has read your message.

3. Ask for reading confirmation: Some applications allow you to ask the other party to send a receipt to confirm that they have actually read your information. When the other party reads the message, you will receive a notice or receipt.

4. Open the delivery report: enter the SMS settings and open the "delivery report" option. When the other party receives a short message, it will receive a prompt and display whether the other party has received the message on the short message details page. If the other party has read the short message, the page may pop up a prompt that "so-and-so has received the message".
