I have been using this device for last 4months now. And I havnt found a single drawback.
Pros:
Good camera
Good battery backup
Charging time is good
Fingerprint scanner is fast
Face unlock is awesome ( better than S9. Based on tests)
Cons:
Camera ( which can be improved with some settings. You can change them watching YouTube videos)
Design
Conclusion:
This is a phone which you can buy under 15k
Go ahead for it
