Forward a message
In the name of creating the flattest, most Spartan interface possible, the forward controls are hidden behind a few touch gestures.
Tap and hold the message you'd like to forward; when you do, a pop-up with a few different buttons (such as "Copy" and "Speak") will appear. Tap the More button, then tap the little forward-arrow in the bottom-right corner of the screen.
Find out when a text message was sent or received
Silence an annoying group thread
Open the group thread that's bugging you, tap the Details button in the top corner, scroll down and flip the Do Not Disturb switch.
Ah, the sound of silence.
Delete old text and picture messages automatically
An individual text message takes up a miniscule amount of data on your phone, but eventually, all little messages will start to add up—particularly if there are pictures or video clips attached.Luckily, Messages has a handy setting that'll trash older text and picture messages automatically, perfect for keeping your phone's storage from getting junked up with ancient threads:
Tap Settings > Messages, then scroll down and tap Keep Messages (under the Message History heading). Then just decide how long you'd like to keep old text messages before they're deleted: for 30 days, a whole year, or forever and ever. In case you're wondering, no—there aren't any custom settings.
See all the photos and videos in a message thread
The good news, though, is that the latest version of Messages for iOS 8 lets you view all the photos and video clips in a given message thread all at once.
Open a thread, then tap the Details button in the top corner of the screen. Scroll down to the Attachments section, and there you go: Every picture, video clip, sound file, or any other attachment you've traded with a fellow texter will be right there, ready to be saved, forwarded, printed, or simply opened.
The only thing you can't do with the files in the Attachments section is select them all at once—or batch-delete them (or delete them at all, actually). An annoying omission, no question.
