Lenovo vike k4 note is best phone I have ever used. I saw this phone on amezon, it looks cool and awesome, then I saw the discription then I decided to buy this phone.
It has 3GB of RAM which helps the phone to work smoothly. Internal storage is also nice. You can insert external storage also. It has long lasting and non removable battery. Phone charger is also very fast, within 90 minutes phone will be completely charged. Phone has dolby atmos system which helps to listen music in high volume. This phone supports VR , because it has theater max screen which is very good experiance.
The only drawback of this phone is it gets heated after some time use.
So if you want a phone under 15000 then it is best phone, you can buy it
