Mi is a good brand but this time they not deliver a good product.
Always xiaomi gives us a better phone in low price that why they rule in india
but this time xiaomi change his way they increase his price very high and add only screen finger touch and front camera and price increase 10, 000 compare to mi 7 note pro , vivo oppo gives and real me gives also a better phone compare to xiaomi in this price so I suggest you don't waste your money to purchasing a xiaomi red mi k 20 .
And one more thing that is some time audio jack of this mobile is not working properly so reboot again and again then that will work properly.
