Samsung S21. I buy my 'phones second hand, reset them and hope the storage and bootloader haven't been compromised.

Samsung's T&Cs imply that the company records all location activity whenever GPS is switched on, that's the biggest privacy concern IMO. I still use it for big journeys as most sat-nav apps are good at routing around delays.

I deny camera and mic access to most apps, but again I'm relying on locked-down software to make that work.

On the plus side, it's easy to get spares for flagship 'phones, and videos showing how to fit them. I like the current implementation of Dex (connect a screen and get a not-too-bad desktop) and "Secure Folder" (a sandbox for apps and files, I use it to run a few apps that try to send my address book to their mothership).

Replaced my samsung 10e for a nothing phone 1.

Well, I have a BLU cell phone but my contacts and phone book (and browsers, and games) are about all I keep there. I use the phone for texting, phone calls, playing, browsing, and reading and that is about all. There is a bank app, but the security on that is so strong it is difficult for ME to use and I know all the codes! I have a medical app, but it has similar security and holds no data in the phone (it connects to my medical providers servers. Reluctantly!).

My cell phone had all of the features I needed, made in the USA, and cost me about $200 new. It had extra memory and storage, and a fast processor, because it was designed as an entry level gaming phone. I got it nearly 4 years ago now, and it has not failed me. (The two years and more without an OS uplevel is starting to bug me, so I may get a replacement soon. Still not spending any $300.) No kind of idiot would risk years in jail and a broken neck to get this phone, but it is more than I need.

I once got my wife a $1200 Samsung top of the line. Most worthless waste of electricity and money I ever owned! Never again!

And I had to use on of those little fruit phones for a job for a year. Best music player I ever owned, but a HORRIBLE phone! I will stick with Android or a Linux phone, and not waste the $$$.

Here's an article comparing iOS and Android security. The article gives iOS the edge, but, neither phone is perfectly secure.

Is this about mobile ('capable of motion on its own') devices or telephones? My first mobile device was a four Opteron 880 CPU Tyan K8QSD Pro system-/logic-board full-tower workstation desktop PC on wheels (heavy enough it remained on floor, by some definitions minicomputer rather than microcomputer, and 'mobile' only meaning you had to push it) that was 19.2 GFlops when most high-end desktops were 1 GHz (1 GFlop). I haven't had a mobile device since, though several portable. My main portables are late 2010s to early 2020s Lenovo ThinkPad X1 Yogas (which are phones, but I don't use that part) and a Lenovo ThinkPad T500 that can run LibreBoot. My favourite phone is an American Telegraph & Telephone (AT&T) Trimline, because it gets all electricity from phone wall socket, so in power outage still works unless phone company's lines lose power (sometimes happens after several hours or days).
