First of I want to talk about the stock android, by giving the stock android in MI A1 is wonderful it offers more customization so that the user has the full control over his/her device I been using this device since 6months it is champ till now I am going to divide the best and near best features below
Pros:
1.Dual Rear Cameras to capture in-depth and vivid images
2.Clean and pure Android experience
3.Unlimited photo and video backup via Google cloud
4.Dual pyrolytic graphite sheet to avoid overheating
Cons:
1.Hybrid sim slot
2.Battery capacity would have been better
sound reception of this device is excellent
style is awesome
looks like a premium mobile but the mobile is budget range
more of it is that is value for money
