I have a Samsung Galaxy S9 at the moment, but Samsung's typo-filled changelogs don't exactly inspire confidence. It has also been bugging me to accept the new Samsung Account terms, which I don't want to do.
Chinese brands (Huawei, Xiaomi, Motorola, etc.) don't inspire confidence for me either.
Apple had the CSAM scanning controversy. I have an iPad, but a bunch of features I didn't want were turned on by default, and the walled garden approach is obviously a downside.
I would prefer to run a privacy-focused Android distribution, but I have a lot of apps and I don't know how much they depend on Google Play Services, so I don't really want to switch over 'cold turkey'. Also, they're still built on the same AOSP base, so who's to say they don't have the same bugs?
