I have a good experience using redmi 3s smary phone. it is tha best budget smart phone introduced by redmi.its camera and battery capicity is its best feature.ih have a bettery capacity of 4100 mah.which last long for more than a day.which not every smart phone have. Also it have a camera quality of 13 mp.which is quite enough to capture beautiful life memories. having 16 gb internal is also a quite feature of it.The most amazing pre installed aaps impressed me alot like DUAL APP N SECOND STORAGE.by using dual app u can manage ur professional n daily life seperately.it is a quite good feature of xiaomi.also second storage, makes ur single smart phone to 2 smarts phone.which is also a good feature.overall I submit 5 stars to mi 3s
