Xiaomi Mi A1 is really good in this price.Rear Camera is too good but in low light performance not good as compare to daylight performance.Rear Camera is giving very smooth blur effect. Sound Quality is too rich we can hear the sound clearly and loudly. Design of this phone is too impressive.I have not face any in built problem till now like heating, hanging etc.But only the problem is that this phone is leading to loss of too much data comparing to other phone.which I have used till now.This phone is not giving you inbuilt gallery and file explorer.This phone don’t give us fast charging like other xiaomi device.As other Xiaomi device are having SECONDE SPACE, QUICK BALL, ETC.But as this phone is stock android this does not have this feature.Lastly I conclude that if you need a best camera this phone is best.
