That was my first and last Android phone however. If you think Android is a decent OS try removing Google from it.
If you are ok with Android, Sony hardware is good. Was my second favorite phone vs my X. The screen was 4K and the audio was great for a phone. It was on the heavy side but well built. Lots of battery.
Actually that was one of my favorite things about my Xperia XZ1 Compact: running LineageOS without Google services. The battery life was insane, like 10-12 hours of screen-on time. I simply did not have to think about charging the thing; I'd charge it every 2-3 days.
Having a device that I could readily bootloader unlock that also has official AOSP support complete with device trees direct from Sony was such a refreshing change for me after years of hacking together homemade device trees for various LG devices.
I regret trading that phone for an LG G7, with its mediocre battery life, heavily bloated, laggy software, and precarious glass build -- also cannot ever be bootloader unlocked, and even if it could you'd have to rely on some community approximation for the device trees, forfeiting fully-functional camera support.
