As of the latest update, Twitter is testing the edge-to-edge view feature of photos for iOS users.
Being a visual network, Twitter pays a lot of attention to visual performance. That’s why Twitter is testing the edge-to-edge view feature, which gives photos a larger and borderless view.
Due to this feature, users will be able to take advantage of full screen. Now you don’t have to click on the photo and from outside the photo looks bigger because of this feature. This helps to focus even more on the content.
It also helps the company compete with other photo apps like Instagram. People will start using Twitter more as more people start watching content.
