>and Android (for example MIUI) is not worse than iOS //

I prefer stock Android but my latest phone has MIUI. It's OK, but I don't want someone else's tailoring I want my own; why can't companies offer their own settings but leave devices open for those who want to change. Yes, "support" but just have a "support and warranty will be limited by changing this setting" with a tick box and an "are you sure?" nag and let me return my device to stock. Grrr. /rant
