No, and you would not want one anyway.
A hardware wallet should be 100% offline.
No potential for it to send data someplace or for some other way to connect without the user physically doing it.
No potential for someone to install apps that may compromise security no possibility to run something that should not be run and so on.

I see. You make solid points. I take it the main issue with being online is non-consensual touchy touchy from adversaries?
Also, could the phone just have an isolated operating system inside of it that doesn’t actually recognize the exterior operating system of the phone, but can still function to sign transactions? When I say recognize, I more mean each other. They both use the same screen but don’t know each other exist in the same piece of hardware.
Thanks again, Dave.
Phone security is
weak.
And about your initial question, I think hat Samsung had ideas in that direction, but a quick search has only revealed
this topic (2021) and
this one (2019) on the matter.
For sure, phone's security are terrible when they are online. But and intermediate can do things like:
1.) Get a VPN and set it to where it's on as soon as the phone turns on.
2.) Airplane mode and connect to a secure internet connection
3.) Virtual Machines (Although I have read before that there could be malware out there designed to escape virtual machines).
Fillippone comes in hot with validation risks right off the bat in the 2019 thread.Negative because of
1. Security 1. Validation risk: who programmed the wallet? Where is the source code?
2. Security 2. surface of attack. Embedding the wallet directly on the phone greatly improves the surface of attack of potentially malicious attacker.
3. Privacy. Embedding a wallet in a phone link my wallet to my IMEI, that is linked to my identity. That phone comes with an embedded KYC
4. Personal security. Hanging around with such a phone signals you are interested in crypto. So you are exposed to physical attack. Even if you don’t actually hold any crypto in the wallet you are exposed to such a risk. (here an always relevant XKCD strip:
https://xkcd.com/538/)
Instead I cannot think of a single advantage of carrying such a phone, instead of a regular phone with an open source app installed (second best, apple with a well known wallet)
And it's true, open source is the only desirable form of software because you can verify it. Also, there he goes, mentioning that if you have a crypto phone, one can immediately point you out. On the flipside of that, don't we want something that everyone can easily adopt? I think phones might be the answer but they are so shit for crypto right now.
Furthermore, the 2021 thread you linked mostly had people discussing corporations and how their closed source hardware might not appeal to bitcoin holders. And that shit is definitely going to be closed source bet on your mama.
