Samsung is working on a new 150MP photo sensor that will equip the top 2021 phones. Like the current 108MP sensor, Xiaomi will be the first to implement this sensor.
The new sensor will have a size of 1 inch and is the successor of the current 108MP sensor. Use Nanocell technology and use 9 pixels to simulate 1 2.4um pixel. That is, when the light is dim the pixels are combined and you will get a 16MP photo. This translates into a greater absorption of light and automatically a very good photograph in low light conditions.
So, next year we can expect the Galaxy S30 with 150MP sensor.
