I hate the analog time picker, can I force apps to use something else?
As a developer, I'm not even sure you always get analog/digital time-picker on all apps. If I remember correctly, these time pickers are implemented and used only on Google's apps. The rest of 3rd-party apps will show this type instead:



I'm afraid it's impossible to force using the time picker you want since each app has its freedom to use any picker that the developer want. (As reference, there is a 3rd-party library that implements the digital time picker from previous Google Calendar, but it's only useful for developer).
