Best phones under 30K

If you have a phone to exchange and an HDFC credit card, try the Pixel 7 Pro during the Big Billion Days sale. Though it's two years old, it will get updates longer than any other phone in this range and has all three types of cameras. The only con is its average battery life.

Even I'm thinking of exchanging my OnePlus 8t as it's almost 4 years old now. Suggestions open.

I would go for these brands only: OnePlus, Motorola, Xiaomi and Samsung. They actually put effort into maintaining software quality for the long run.
