I set up a routine in my samsung phone using modes and routines app . I set a shortcut to start voice recording if I press volume up button twice .The issue is if I accidently press twice to volume up while watching something , it starts recording ....
For yellowish tint , you can try turning off "eye comfort shield " and control screen warmth under display settings . Change it to cool or normal . My s24fe camera works well , just it is not good in night .
