Xiaomi is trying to take low ranged and budget oriented smartphones in India.Xiaomi redmi 4 is one of them just like redmi 4a. All are same. But only finger print sensor is available in redmi 4.Redmi 4 is featured snapdragon 435 octa core processor with 2gb ram, 3gb ram variant with adreno 505 gpu. Which is great in day to day performance and normal to moderate usage.The design and built quality is okay in terms of price point but just like redmi 4a.The rear camera is 13 megapixel and front camera is 5 megapixel which can take good photos in daylight. It can record upto full hd videos.The battery of this phone is 4100 mah which is easily lasts upto 2days and with heavy usage it also can lasts a full day. Battery slightly heat up during heavy usage or graphic intensive game play.Display is 5 ips lcd hd screen with 2.5d curve glass.The sound quality is average. The call quality is good also. Speaker and microphone is good enough.This device is not value for money though big battery and finger print sensor in its price point. All essential sensors are available. Still with more money you can buy redmi note 4. This is not a value for money product.
