Only flagship S22 series phones got Lockscreen AOD transition effect but not for the S21 FE model. Why samsung doing this differentiation as its not a very very imp feature to be implemented only for S22 series. It should be given in One ui 5 to S21 FE model also.
Another feature which is absent in S21 FE is Voice Focus mode for calls. Ehile its present in some models of A and M series phones with One ui 5 update.
Transition effect dont require necessarily the ultrasonic fingerprint sensor. Its a software related feature and its possible to implement it in any amoled display. Samsung discriminates FE series with the flagships.
