Chances are that the rumored 150MP sensor will be reserved for the highest-end Galaxy S model. The other models could supposedly get upgraded to a 108MP sensor. And it wouldn’t likely be the 108MP camera seen on the Galaxy S20 Ultra.
Galaxy S21(S30) could come with an upgraded 108MP sensor
The new sensor is seemingly codenamed ISOCELL Bright HM2 and it also has a resolution of 108MP. If you recall, Xiaomi also got to flaunt the co-developed 108MP sensor before Samsung last year and the South Korean giant refined it further before putting it on the Galaxy S20 Ultra.
As for the maxed-out Galaxy S21, it will reportedly boast a 64MP telephoto camera, a 16MP ultra-wide shooter, a 12MP macro sensor, and a VGA-level 3D ToF camera, in addition to the 150MP snapper mentioned before. It is believed that both main and telephoto cameras will offer OIS.
If the bit about the 12MP camera is true, it would be the first time Samsung uses a macro shooter on a Galaxy S phone.
