The existing Week view in Calendar is too busy and cluttered.
This is in both Desktop and Android Mobile.
An additional Week view layout that shows just 7 days, without the full list of times displayed would be a better user experience.
The Android calendar app "aCalendar" by Tapir Apps has a much nicer layout for the Week view.
See below for example screenshots (fifth screenshot is the Week view):
