I don't bother with Samsung phones after my first, after I found that their custom keyboards started crashing and freezing (Chinese mode), and then started to reappearing over the Google ones I set after each automatic app update. My only regret, is that I didn't pay the Apple tax earlier. (I'm sure there is a more permanent solution to that phone, but why should I sink more time when I'm one update away from fixing some other issue again.)
If it weren't for the manufacturers, I'd like how you can customize an Android phone. Its the best feature of Android vs IOS. However, between the poor quality customizations and the delayed to non-existant updates it leads to, it's also Android's worst feature.
