Budget 30-40k A good Smart phone under 40000

I have a Oneplus 3 and I am thinking of upgrading now. Can someone suggest a good phone under 40000. I like tinkering with my phone and hence I like Oneplus as their warranty remains intact even if we root the phone. Open to suggestions.

Why not get OP8 putting 4k more? YOu will have get your old brand and best bang for the buck!
