iPhone 7/Plus Screen went big - How do I fix it?

[jmm55]

I have an iphone 7+. While setting the phone down yesterday I accidentally hit some permutation of buttons that made the screen image giant. Now I can only see the numbers 2 5 8 and 0, on the pad, and have no foggy way how to revert back to normal. Can anyone advise on how to do that?

 

[now i see it]

Quickly tap the screen twice with three fingers together.. It's a magnifier feature.
Tap the screen three times with 3 fingers and it'll bring up the screen zoom settings
When screen zoom is enabled in Accesibility, tapping twice on the screen with 3 fingers will zoom it in to your setting

It worked. Thank you very much.
