I bought the new Redmi 6A one month ago. But this smartphone is built on mediatek processor, and that is why it lags a lot.Simple browsing can also become a pain. The battery in only 3, 000 mAh, it drains really fast. The UI is actually great. If you update the phone, you will experience the new UI.
My overall experience is Somewhat satisfied.
If you do not have a smartphone, and you want to get a taste of it, then this is the perfect smartphone for you. Actually for ₹6, 000 you are getting a smartphone, that in itself is a big deal. The camera quality is below average. I am attaching some photos taken with Redmi 6A.
