iPhone-only app layout in iPad with iOS 9

[malih]

I notice that the iPad uses iPhone 4S 4:3 UI when displaying iPhone-only apps.

Is there a non-Jailbreaking way to change that to, for example, use either iPhone 5 or 6 Plus 16:9 UI.

And for those installing Beta 2, has this behaviour changed in iOS 9?

Edit: iPhone 4S display is 3:2 not 4:3, as corrected by blindside217, The Doctor11, okay of course technically it's also 2:3

Unfortunately they are still using the 3:2 UI. They should be using the iPhone 6 Plus apps as those would be the highest res and closest to the screen size of the iPad.

The iPhone 4S was 3:2 ratio. I am not sure about the behavior as I refuse to run iPhone only apps on my iPad.

Thank you for correcting me on that.

I do think there are possible performance issues older iPads, but newer A7 iPads should have no problem.

Thank you for correcting me on that.

It's actually @blindside217 who deserves credit for the correction. In my original post I had wrote 4:3 because I didn't know the ratio and assumed 4:3 was right. Then when I saw @blindside217 post I changed my post to say 3:2. Lol thank you @blindside217.

The thing is I like editing photo with the iPad's big screen, but then I hate that I have to transfer back to my phone to post to Instagram, so I just install Instagram on the iPad instead.

I'm a little surprised they still use the original iPhone dimensions as well.

Possibly when they hit 64 bit that will change?

Most likely Apple doesn't want iPhone-only apps to look good on the iPad. It's probably their "subtle" way of trying to get developers to optimize their apps for the iPad.

If an app is iPhone-only and looks like garbage on the iPad, users will complain; and if enough users complain, the developer will give users what they want. And then Apple has another app to add to its iPad app count.

All iOS devices currently sold by Apple, except iPhone 5c and iPod touch 5th generation, are 64-bit.

I would love to see the 6 Plus dimensions, but the reason that they use the 4S dimensions is because it is capable of filling the iPad's screen. Think about it. (WARNING: some may not be able to understand the following) The iPad has a base resolution of 1024x768. The 4S, 480x320. Double the 4S resolution, and you will get 960x640, which can fit in the iPad's screen. If you did the same thing with the 5, it will end up taller than the iPad. Same with the 6 and 6 Plus.

So you say iPad in fact has this 768 base resolution, even on iPad Air 2. Then iPhone app on taller screen will not be able to display well on iPad because they have different base resolution?

No, on the 1X option (the one where it is about the same size as on the iPhone, any of these will fit, but if you use the 2X option, which most people use, then the size of the image has to double, thus not fitting on the iPad screen if you don't use the iPhone 4S resolution.

Oh. Thanks.

And what you are saying is this. I though what you were saying was split view in iOS 9.

I know this, I meant when iOS is 64-bit only, as it also runs on the 4S, 5, iPad 2, iPad 3, iPad 4, and iPad miniz

Yeah that's right this would result in overscan, the options for non-retina iPads would be to either lock it to 1X or downscale it to something like 1024x576.
Does anyone know of any iPhone apps that have dropped support for the 4S and the 3:2 UI yet?
