How to change the tip size of the iPhone markup tools
Submitted by Marshall Walker on
iOS 12 didn't deliver much on the side of features, but it did add the option to change the opacity and tip size of Apple's markup tools. In case you didn't know, your iPhone allows you to markup photos stored on your device. To do so you just need select a photo from the Photos app, then tap the Edit button, and finally tap the 3 dots in the bottom tool bar to bring up the Markup option.
