I'm upgrading because my phone is losing (lost?) support. I use a OnePlus 7 Pro and love it and wouldn't bother upgrading otherwise. I'd appreciate some recommendations of android phones you like, please.
I've never been an Apple guy and I stopped finding Samsung acceptable after the S10. My answer has been to go to Sony's Xperia 1 line. I have a 1 IV and, honestly, I'm pretty happy with it. Point and shoot photos aren't great on it, it really is meant for manual photography, but it's not bad, either. The reasons I went for it were the form factor, the lack of a notch or punch-hole, the external SD card support, the physical 3.5mm jack and the front firing stereo speakers. It's nuts what you can get when you don't obsess with not having zero bezels.
The downside is... well, I don't trust Sony for long term support, either. It helps that their phones are very similar outside of updating to the latest processors, but they clearly aren't super focused on software updates, if that's your priority.
But yeah, hey, screw Samsung, Google, Apple and their dumb ecosystems and actively removed basic features. This thing is easy to use one-handed, has very solid hardware and is not a clone of those three despite having flagship internals. It's expensive, but I'm also gonna use it for multiple years, so I have no regrets about it at the moment.
I get you don't like Samsung, Apple, or Google, but man... Sony? They are the original electronics company bad actors. That's like saying "I don't like Dahmer, but this guy Manson is cool" what the hell?
I don't dislike the big three's phones because I have a moral stance about them. I dislike them because they've removed features I want and added features I don't want.
Sony makes a flagship with a headphone jack, front firing speakers, a hole-less screen, hotswappable removable storage and dual sim support? Cool, got my money the old-school capitalist way.
They start messing around with that stuff or enforcing crap I don't want, they'll lose my money the old-school capitalist way.
For the big bad stuff all of those companies do I don't vote with my wallet, I vote with my vote. Regulation and policy are the answers to those.
