Why is there a 1 in the upper right corner of my iphone photo that hasn't been updated or something?

You need to confirm the version of your mobile phone first! ! Recommended IOS 10.

The message prompt is that there is unread information, so you need to click that information! Entering the information interface is not OK!

Photos are prompted because one of your albums is alive, a photo application has created a new album, or you have opened the location of the photos, and so on!

The APPSTORE specified program has been updated! ! ! Just update!
