[SOUND] iOS 9 has plenty of surprises up its sleeve.
Here are some hidden features you can find.
Selecting multiple photos used to be tedious by tapping each one separately.
iOS 9 now lets you select lots of photos with one action.
Go to your Camera Roll and press Select at the top right.
Now touch, hold, and drag to choose as many as you like.
While we're talking photos and video, iOS9 lets you change recording resolution.
Go to Settings, Photos and Camera, then choose between 720p video at 30 frames per second or 1080p at 30 or 60 frames per second.
Same old selections apply to the slo-mo video where you can choose a frame rate of 120 or 240 frames per second.
Also new in video play back is the ability to pinch zoom in or out.
When you're typing out messages, you might notice that the keyboard switches between upper and lower case letters.
To keep it all upper case, head to settings.
General, accessibility, keyboard, and toggle off show lowercase keys.
Also in the settings app is a search bar at the top.
Quickly find a feature you wanna change by typing in something like keyboard.
IOS 9 now has a back button.
When you're following links between apps or checking your notification, a back button appears at the top left.
Tap it and you return to the previous app.
No need to press the home button to open the multitasking menu.
Add drawings or markups to image attachments sent over email.
Just open the message, tap and hold on the attachment, and select Markup and Reply.
Draw a text or even insert your signature.
Those are just some of the secrets inside iOS 9.
