The iPhone 6 and Samsung Galaxy S6 will both shoot 4K video.
If you don’t already have one, you’ll need a very powerful computer and software that can handle 4K video as it’s 4 times the size of regular HD video which means a much bigger strain on your computer.
I have no idea what apps are available nor how much the phones costs.
If it’s the iPhone you’re thinking about, your best bet is to go to an Apple store and talk to a product specialist who can answer your questions.
