All modern touch screen phones are compatible with a stylus. I'm sure it would be harder to find one that isn't. The accuracy may not be the best on budget models.
Unless you mean _is a stylus / pen included with the phone_?
I have a Samsung Note. It has the best stylus on a phone.
(I also find it funny the Apple Fanbois decided to downvote my initial comment, when I was clearly showing that Apple is 'behind the curve' in this respect. Gosh, I used to work at Apple. I find this amusing.)
I didn’t downvote you, but surely your very niche requirement doesn’t add much to the discussion.
Even though, that is very cool line of work and I’m sure I would be similarly biased for the tech I helped form, but it is simply not a general requirement as shown by very very few phones having them.
You won't have much luck trying to combine an official Apple stylus with an iPhone. It's kind of a shame with how big phones have gotten over the years.
Samsung has some phones that have the necessary screen support for their styluses, sometimes even if the phone didn't come with one, but that's only in very few models.
There's the Apple Pencil, currently works on iPadOS but I don't see a reason why apple will not push the features to / it will at least be incorporated within the blend of macOS, iOS, and iPadOS.
I can currently use the Apple Pencil as a _dumb stylus / pen_ on my iPhone 2022 SE (not that it's necessary but just to see if it can be done).
Yes I meant a stylus is not only included, but integrated into the device. I thought that would be obvious, but I was wrong. Thanks for letting me add that important detail.
