I bought micromax canvas nitro 2 E311 grey colour phone 1 year before from amazon shop.Phone slim, its back cover nice, very light weight phone.It have separate port for memory card.Sim port micro sim size.Its battery backup very nice loaded with 2400mah battery.It fall down several times but screen not broken because of corning gorilla 3 screen.Its build quality nice.It have decent 2RAM, 13mp good rear cam and 5mp front cam.But its main disadvantage, you cannot use 4g sim.so Your internet speed goes slow.It accept only 2g and 3g sim.If you use wifi its internet speed nice depends on your provider.In my case wifi working perfectly.Its rear camera not waterproof.so care in rainy season.compass/magnetometer sensor not available with this model.Otherwise amaizing phone.Its box doesn’t contain any silicon cover or flip cover .But screen guard with this box
