What phone should i get for 20k?

Hey guys, I’m looking to buy a new phone during the Big Billion Days sale and my budget is around ₹20,000. I just want to know the best bang-for-buck option right now in this price range. Longevity is important for me (planning to keep it 2-3 years), so any suggestions with good performance + decent cameras + software support would be great.

What’s the best bet under 20k right now?

Thanks in advance!
