It's the best phone I've had until now.
Excellent build quality (considering the price). Very fast and excellent graphics. I think that also has a good camera (when light), because when not using the flash, and when there is low light the pictures leave little to be desired.
love the MIUI rom, I am fan. Everyone should try this rom.
I think it is good value for money.
The Mi2s is the best phone I have ever owned. It runs on MIUI, which is an operating system based on Android 4.1.2. Currently, MIUI is being upgraded to Android 4.2. Unlike most phone companies, MIUI is upgraded WEEKLY... not every six to twelve months like most OS's. The battery life is much better than what is posted here, I charge the phone every other day with moderate use. Under heavy use, the battery will last more than one day. I have the 32 GB version that comes with a 13 MP camera. It supports full 1080p and 30 FPS. Pictures and video are excellent. It has a slo-mo feature that records at 90 FPS. Calls are crisp and clear with AMAZING reception. I had an iPhone before and in places the iPhone had no service, the Mi2s has TWO BARS! As for speed, this phone has a 1.7 Ghz snapdragon 600 quad core processor that blows away the Galaxy S4 with it's octa-core processor. Music is handled via Dolby Digital Plus and, in my opinion, puts Beats Audio to shame. I'm not fond of the keyboard, but it can easily be replaced with a different one from Play. It doesn't have LTE, which is fine with me. I still get 42.2 Mbps down speed through DC-HSPA. LTE is power hungry and eats up the battery, so the trade-off is more than worth it. Other phones that are tied to a charger all the time aren't really so "mobile" if you ask me. MIUI is completely customizable... from the icons, to the top bar, to the notifications... everything can be changed to suit your tastes. The browser isn't top notch, but again, you can get a different one from the Play Store if you want. It has the do not disturb feature, built in antivirus, built in firewall (call and text blocker), built in data usage recorder, root control, and app control which allows you to control each app's access to root, data, wifi, SMS, phone ID, autoloading, etc. Currently it's only available in China, but you can order it online through various "amazon-like" venders in China and have it shipped to your door via DHL (3-5 days) or Fedex International (4-10 days). Only use vendors that accept Pay-Pal and you should be safe. This phone is unlocked from the factory by default and works with any GSM carrier.
