Can you target specific iPhone models, like iPhone6 only?
I'm trying to do a splittest for a fixed CTA that will follow when you scroll down on mobile.
The position varies though depending on screen size, so I would like to test it on only one device model like for example iPhone5 or iPhone6, but as far as I can tell you can only target iPhones in general?
Is it possible somehow to target it to a specific model?
I haven't tested this in an actual audience, but I created an illustrative fiddle at https://jsfiddle.net/zy8x94st/. You can use Chrome's device mode to test out this targeting strategy (see attached screenshots). I also tested this on my test iPhone 5c.
Note that an iPhone 6 using the Zoomed display will look like an iPhone 5 for this targeting, and similarly an iPhone 6 Plus using the Zoomed display will look like an iPhone 6. But I think that's fine if you're just trying to ensure your experiment only targets the resolution it was built for.
Hope that helps!
