I have been using lyf wind 4 since last 3 mnths. The phone has 5.1 lolipop version 5 inch screen 1 gb ram 8 gb rom( internal memory) and best part 4000 mh battery with a reasonable amt of 6799. But as I purchased it, the handset got out of the stock online as well as offline. Many of my frnds were very much eager for this phone but now its out of stock. Smooth performance solid battery backup reliance jio net is powerful 4g. I would recommend 101% to go for lyf phones n in particular for this model if in stock.
