There should be an option so screen NEVER blanks, even when on a call. Without thinking to hards here's are some reasons why: 1) Often when on a call I am required to use the keypad to enter numbers 2) Often I am using phone one handed while on a call. 3) Often I need to check "info" 4) Often I need to look at photos while talking. 5) etc... Samsung's paranoia on Battery usage is OTT. Because I manage my phone usage I have no trouble getting my S9 though the day, usually at 50 - 60% at end of the day. Summary: Samsung really should add a simple setting to completely override screen blanking, for all use cases, even when on a call. The only override should be a brief push on the power button to blank the screen. Please !
