The phone hangs frequently out of the box. The clock application freezes the phone as well as random resets to the lock screen saying that Android system has stopped working. This is absolutely atrocious- why market a buggy phone in the first place! I still own a Xiomi Redmi 1S and the phone actually worked right out of the box without any tweaks.
Voice quality was very poor and even on a speaker phone the LETV customer support was barely audible.
Flash sale fraud. Many hapless customers including me brought it in a flash sale because of the hype generated. Also there were many glowing reviews( maybe paid ones ) on this product.
