I have used lyf wind 4 , it is a stylish looking phone with a good back camera & a everage front camera , its battery is very powerful 4500mah so it can be use hassle free for hours, wind 4 comes with dts sound quality its good but not as dolby , it has 1gb ram that is very less then others, it dosent have hybrid sim slot so its a plus point , now you can buy many nice phones by adding 2-4000 in this phones budget , why what r u waiting for, .
