Hi this is kriahankant.todat I’m going to review the another product by xaiomi REDMI 4. BUILT QUALITY: -The built quality of xaiomi REDMI 4 is very good like many high range phones, it has a metallic back with upper and lower side with plastic and it has a 2.5D curved glass and the phone feels very good and solid in hands. SOFTWARE AND HARDWARE: -redmi 4 comes with snapdragon 435 which built on 28 nm technology and have adreno 506 GPU.It comes with Android 6.0 marshmallow and runs on miui 8.It has 13 mp rear camera with aperture f/2.2 and a 5 mp front camera with aperture f/2.4 and another good thing we get all the sensors in this price range. GAMING : - As I tell you it comes with snapdragon 435 and adreno 506 GPU it can run a normal games very well but in very high end games like asphalt 8 and mortal combat I sees it has some ui issue and I think that for heavy gaming it is not good but for normal gaming it is very good and you didn’t have any issue in gaming. SPEAKER AND CELLULAR CALL QUALITY: - the speaker output was that good because sometime it is not audible to me when I travelling somewhere but the headphone output is very good and I run this device on jio network the cellular call quality was very good and I also take many call via speaker it is also very clear and you didn’t have any issue about that. CAMERA AND OVERALL PERFORMANCE: - The overall performance of the device is very good and the only thing I don’t like about phone is it’s camera because in low lighting the photos are not good but in natural light the camera works very well and I recommend you to not buy this phone if you needs only camera. And for those for camera doesn’t matters then it is very good phone at this price range. Thank-you I wish my views will helps you for your best decision.
