Why would it be better in a week when others are blueish from the beginning... makes no sense to mePhone hot? Let it settle for a few hours
Battery life bad? Give it a few charge cycles
Screen yellow? Give it a week or so to cure
With every new release, update, etc all three of these get posted. What is the common answer.....chill. Have some patience, enjoy your device. These things usually always resolve with a little bit of usage.
