As a technical journalist, I researched whether iPhone notifies the sender when you take a screenshot of their messages. After thorough investigation, I can confirm that iPhone does not notify the sender when you screenshot their messages.
This news will be a relief to many iPhone users who may have been concerned about their privacy while sending or receiving messages. Now, iPhone users can comfortably take screenshots of messages without the fear of the other person being notified.
This information will provide peace of mind to iPhone users who value their privacy and may have been hesitant to take screenshots of messages in the past. Knowing that there is no notification sent when screenshots are taken can help users feel more at ease when reading and referencing their messages.
