I prebooked k20pro from flipcart before launch and received it within 2 days after its launch event. I am using this phone from more than a month. It doesn't show any lag at all. Major benifit of this phone is that it can run high graphics games like pubg in ultrahd graphics that too in smoothly without any lag. Battery bacup of the phone is also good. I can play pubg for at least four hours after the full charge. It gives sufficient battery backup for daily use which lasts at least for 12 hours with normal usage. Battery charges only in 90 minutes from 0 to 100% . Phone has attractive glass back which looks great. However I am disappointed with the UI of the phone which is MiUI which shows ads all the time which is quite annoying. This smartphone comes up with snapdragon 855 which is flagship processor available in the market. Best attraction of the phone apart from the processor is its price. I got it at 27999. It is very cheap compared to the features provided by the redmi however I don't know why people are saying that it is overpriced. In my opinion this is the best phone at its price.
