I purchased this mobile @13999 from mi.com. I am using this mobile from last two months. There is no problem with this mobile. The rear camera is just awesome in this price range. No hangs, pure android , 13 + 13 mp dual rear camera. I was really shocked when I click a celfie with the front camera. The front camera is of very low quality. No heating problem , no hanging problem, battery backup ij just good( 8-9) hours of normal use. The software was updated to oreo. 4gb of RAM and 64gb of internal memory. Gyroscope sensor , ambient light sensor, compass, magnetometer, type-c usb port. It gets completely charged in just 1hr-25minutes.Plus points : - Dual rear camera, snapdragon processor, android one OS, unlimited storage in google photos, metal body, type-c port, sound quality is good, good battery backup, dual mic with noise cancellation technology, face recognisation unlock, biometric unlock, IR blaster.Negative point: - Bad front camera, low light camera quality is very bad, cannot use 2 simcards + memory card simentaneously.
