Nerd Filled Icon in iPhone Style

This is a Nerd Filled icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,600 icons, all in the same style and quality.
It's a logo to represent a nerd. It is an emoji face with a curved downward mouth to indicate deep thought or sadness. The face has no nose and glasses with only the frames showing.
