I remember folks even here (before I had an account) saying 'folks don't need skeuomorphism to use a phone' all the time. OF course I didn't need it, I thought it made using the device so much fun (and why I became an Apple fan circa 2010 when I was handed my first iPhone, replacing an old Nokia 5185i) and my device literally became whatever I wanted it to. I went from lugging a CD player, cell phone, and digital camera to having one device. It could literally turn into a radio (via some internet radio app that resembled an old digital FM transistor radio, complete with LCD display and knobs that worked via multi-touch) or a literal notepad (with torn paper animation when you 'delete') and so on. I loved it. It was so much fun and you never knew how far it'd go, so it made me WANT to find even more on the App Store.
Android's implentation was a bit haphazard. Android 2.1-2.3 seemed like they tried to be skeuomorphic, but not as well thought out as Apple. Devices had too little RAM and too little internal storage to really make it work, too. I did appreciate Mass USB Storage which sadly died for no reason, making it much harder to transfer files from a PC, and I resorted to rooting the device to make up for some shortcomings and to customize them farther. But I still preferred Apple, well, until iOS 7 happened. At that time, updates always made things better so I didn't really worry until I woke up that morning and thought both my iPhone and iPad went into 'safe mode' since it looked so wrong.
But the point stands. I can use flat UI apps/OS, I just hate looking at them. So I usually work around it (if it's the only way) by using Siri or my Watch to do a task so I don't have to look at the screen that much. Otherwise I keep to my tablets, or devices supporting themes or which can do Linux. I keep all my old Samsung phones too just in case I get angry enough and just pop my SIM into them. Unfortunately, the threat of requring VoLTE made me pop their SIMs into some newer phones I kept but didn't use (ZTE devices, mainly. They still feel like classic Samsungs) and the newest phone I have now is an LG Stylo 5, which, while having a mostly flat UI, I made it themed to resemble my idea of what a 6.2" pen-capable Galaxy S4 would be. Lockscreen, sound effects, icons, overall home screen UI, weather widget, and some of my older apps. It also included some long-lost features dumped from most modern smartphones such as a notification LED, a headphone jack, and no notch.
So that makes my iPhone 6S frozen with iOS 13 (albeit themed), LG Stylo 5 (themed, mostly older apps), and ZTE Z-five C LTE (very skeuomorphic, apparently ZTE didn't get the memo in 2017!) and my older Samsung tablets, a Galaxy Note 10.1 (2012), Tab 2 7 and 10.1 (2012), and Note 8.0 (8 inches, not related to the Note 8 smartphone. It is a cellular-capable tablet from 2013)
The Samsung UI, TouchWiz Nature UX (2011-2014) is about as skeuomorphic as iOS 6. It ran on Android versions from 2.3-5.0.1 Lollipop, but retained the Android 2.x aesthetic, such as button themes, icons, certain sound effects, colored notification icons, UI elements, and system app theme. S Note on my Note 10.1 has paper textures and cork board. Smart Remote looks like a brushed metal remote. I use my Mail apps mostly on those since they make sense and look good to my eyes. They retain tablet UI, which made the apps follow the aspect ratio of a tablet proper. They have front-firing stereo speakers. Pens. Basically they did then what an iPad Pro does today. Quite ahead of their time.
I have to disagree with your distaste of classic design in vehicles though. I would pay a ton to have a comfortable Buick LeSabre with pillowy plush seats any day vs. dealing with numb butt on a modern 'luxury' car. I hate how homogenized vehicles have become, where I can't tell my Saturn ION from an identically-colored Nissan Sentra. I also hate this obsession with grilles that make front-end collisions pretty much instant-total (huge grill fad) of the vehicle if it so much as bumps a fire plug (there's zero impact protection and the radiator is exposed)
I really do miss the old days of landyacht cars. I loved how each was unique. I was a total fan of the '70s cars with comfy interiors that felt great on a long trip and were well made. I had a 1984 Chrysler Fifth Avenue until 2013 when it suffered the common 'will eat tires every 2,000 miles no matter how aligned it was' issue along with rising gas prices. I miss those tufted seats though.
