Yellowish line on the screen. Review on Google Nexus 6P

I purchased this phone two weeks back. It is very good android mobile, but I am writing this to warn the potential buyers about the yellow line on the screen. I am awarding this mobile three stars only because of the issue and not based on the full review about this mobile. This mobile is very sexy and does every task I throw at it with ease. I purchased this mobile because of it's mind blowing features. It's fingerprint sensor is very good. It registers my fingerprint commands ninety nine percent right.

There is a Yellow line so the white colored app drawer looks yellowish. I assume this is a hardware issue as even factory reset did not help either. I used to be big fan of Flipkart before buying this product from them, the services have been deteriorated very much in these days. Their 30 days money back guarantee program doesn't seem to be real, instead of n replacing they are asking to do factory reset and other tweaks which even a non tech person knows nowadays.(I am consistently in touch with them about the issue)

I assume most of the Nexus 6P, they are delivering are mostly defective units.
