Application startup usability

From Nokia Developer Wiki
Jump to: navigation, search

Application startup should follow these usability guidelines

  • Starting an application should not take much time, ideally 4-5 sec should be OK. If the application startup is taking more time, a splash screen with a progress bar should be provided.
  • During startup if any audio/video clip is played, the user should be able to control the sound.
  • High priority system events like incoming call should be given priority.
  • Low memory conditions should be handled properly.
  • By default, application should not start by its own. If the application features auto-start at reboot, users should be given an option to reset this behaviour.
