Hello All, Could you help me based on your usage, to help me with buying a new phone. My requirements are: A. Good camera (I am using Pixel 4a which has a great camera. So anything that upgrades it.) B. Good battery ( Again I am using Pixel 4a!!, so iykyk). C. Smooth experience ( Pixel is still smooth). Now Google is offering a cashback in my Pixel 4a, almsot 4.5k. So i am planning to use it. In exchange, I would get around 5k. as well. So overall, I might get around 10k. I am reasy to put another 10k to 12k and get a new one. Non Preferred Brands: Redmi, Poco, Infinix, Realme.
