Which is the best smartphone under Rs. 30,000 in India right now?

My friend was asking about a smartphone that he wants to send to his mother. His budget restraints are under Rs. 30,000. He is looking for features with high-quality cameras, a display, and better battery life. Her mother is travel-enthusiast, and she likes to click pictures more often. So, a good-quality camera is a must. Suggest to me the best smartphones under this budget to gift her on her birthday.
