Both Samsung Galaxy A52s and S20 FE 5G update of One UI 4 has been fantastic. A52s delivers best battery life after update. Great signal reception on Vi and Airtel after update whereas other phones struggles in my area to give good speeds.
It does support band 1/3/8 for 4G. It does not support 4*4MIMO on band 40. If you are using Jio/Airtel as your primary number stay away from it. Apart from that it's fantastic device at 30999. But again S20 FE 5G is available at 27999 with card offers in all retail shops and Amazon in sales. That is far better choice now after One UI 4 update. Again that has only 4*4MIMO on band 41 as it's just exactly same device as US. So network wise not good. If you are casually using phone,then it's no go. Wait for A73 5G, same device as A52s but better camera and better battery life.
