I attended a seminar yesterday and a fellow participant takes photo of presenters from where we were sitting and his phone has the ability to bring the image closer, resize it and capture great quality picture and I was amaze at what I saw.

When I asked him the camera apk he is using, he said is not an apk but Samsung Note 5.

So, which of the Android Note that have this feature, please.
Or is there any camera apk that can do that

Android Note users input is needed, thanks

I'm using Samsung note 4 edge & I have Samsung K zoom which I rarely use it..they have almost same like applications.
