I guess, I am one of the lucky customers who got the xiaomi redmi 1s phone on the first buy. here are the pros and cons which I felt for this mobile:
Great display, front cam at this range is great. mobile look is OK. good camera and resolution.
But a few turnoffs is that it hangs frequently, say 2-3 times a day. but given the other many benefits it offers, I guess, its OK and a good deal. ya one more thing, it has 8 GB ram, and you can’t install your apps directly to the SD Card, but you have to always install them in the phone memory only.
