I really, really appreciate everything you guys do, I really do. The MIUI is a great piece of software but you made a big mistake here. I don't know if this is because you did not use the official ICS S2 ROM or something else but this has way too many bugs. We really could wait another few weeks to get a software that is just as brilliant as the one before but this is almost useless.
I'll name just a few bugs, maybe it will help you. You probably know them already.
1. Lockscreen is in Chinese. I know that you know about this but it just doesn't make sense. But this is not a problem really.
2. For me, the gallery works but I did take a few photos from the start. What doesn't work is auto-rotate in gallery.
3. The phone is way slower then before. For example, auto-rotate when in browser or menus is really, really slow, it takes about 3-4 seconds.
4. When I go into Security and enable Access Control, if I try to select apps to protect it crashes.
5. Some menus are still black.
6. Can't change font. It says that it needs to restart and it does but when it reboots old font is still there.
7. Samsung keyboard is there which is great because it is much more precise then the old MIUI keyboard but there is no Swipe. It would be great to include that.
8. There are two Calendar apps.
9. When I try to add a Facebook account, when I choose Facebook from the list it does nothing. When I reinstall Facebook app it doesn't give me the option to Sync with my existing contacts.
10. In toggles, it says W-Fi instead of Wi-Fi.
11. When you long-press home screen you get a active apps menu. On bottom left corner there is a broom icon. I guess this is equivalent to App Killer in previous version but I don't know if this one really works. On the old one, when I click on "App Killer" it notifies me how much memory it freed, this one just closes the window.
12. The ROM is pretty unstable, I've never had a reboot but the applications would crash.
You have all my support and I know you will fix these things. I just think that we could've waited a week or more to get a proper, stable app. This is now bad for us but specially for you since now you have to fix these things quickly.
Anyway, best of luck!
