Not a recommendation. Just my thoughts, moods, gripes
I’ve mostly really liked the Pixel line of phones. My most recent was a Pixel 3, spouse has a Pixel 5a replacing a 2XL. But they were all 60Hz phones until recently (and then only at the high end) and I do better with a faster refresh rate (and DC dimming) so I bought a used OnePlus 7 Pro on eBay for $370.
The hardware is great, and the battery is phenomenal. The camera hardware is very good, but the default camera software is mediocre. Most photos come out great, but sometimes it handles color poorly. But you can (fairly) easily put Google’s camera on there, or choose another camera app to install. Pixel still takes better low light photos.
The OS is… interesting. Oxygen OS 10.3.8 works really well on it. I haven’t tried the latest updated versions of 11.x.x but the first few were really bad. Some kind of hardware compatibility issue. But… I think the reason is that it may have originally been a “T-Mobile” variant of the phone, but the firmware had been flashed to “international” (aka unlocked). So I was able to use AT&T MVNO SIM cards, not just T-Mobile. But I suspect the minor firmware difference conflicts with the hardware when Oxygen OS 11 is installed. So I’ve been happily sticking to the older OS, which is rock solid, performant, and easy on the battery. Seriously with light use I often get 3+ days - with very heavy use, I still make it through a day. It’s also one of the few phones with a completely unbroken screen (i.e. no notch or pinhole camera, no buttons, the whole front is screen) - it has a motorized selfie camera tucked away. I rarely use it, but it’s a fun feature!
But the phone is really huge! I like that - big hands, and it still fits in my pockets. I do think the OnePlus 8 series is worth looking at, though you likely can no longer get it brand new. The 9 is… OK but they went a little crazy with price. The 10 is out and with a lower starting price, but it’s still “brand new, expensive”. None of those is small. The OnePlus Nord N200 5g is slightly smaller, and very affordable, while still having pretty impressive hardware. It is not a very fast phone, but depending on use case, it should be good.
Edited to add: AllHat reminded me - the fingerprint scanner in the OnePlus is super accurate and fast! To be fair, that’s without a screen protector. I had one for a while, but this has a slightly curved screen, and overall I felt like I was letting an amazing screen go to waste. Gorilla Glass has gotten really tough over the years, and the rubber edge of the case should protect in the case of a normal floor fall. (I’ve dropped it plenty of times.) By the way, I’m a fan of Spigen cases. I used to get the extra thin rubber ones, but on this phone, I got a tougher one that includes a kickstand.
