1. You can access your camera immediately by swiping up on the little camera icon on the lock screen. This is very helpful if you want to take a picture of something happening quickly as it saves you from having to unlock your Iphone or Ipad, input your password, find the camera app and take the picture.
2. If you are at the bottom of a page you can scroll back to the top just by tapping the top of the screen near the digital clock. This is helpful for when you are at the bottom of a long article and want to get back to the top of the page with just one tap.
3. When ending a sentence, instead of typing a period and then a space, just tap the space bar twice. The double tap of the space bar inserts a period, space and automatically capitalizes the next word.
