How do I disable the lock screen on Windows Phone?

By | March 24, 2017

My mother has a Windows phone that she claims never used to have a lock screen (the slide up to open). Hitting the power button would just go directly to the tiles (or last open app I presume). However, she says that after taking a picture one day, the default screen turned into that photo + needing to slide up to unlock. How can I revert this to the old behavior? I don't see any way to do this in the settings.

Information

  • Microsoft Lumia 640 XL LTE
  • Windows Phone 8.1 Update 2

Please do not suggest the following as I've read it elsewhere and does not answer the question:

  • Set timeout to Never (this phone has this setting, but not every phone does and the behavior is not ideal for her usage).
  • Disable the password. I've already looked and there is no password set, so clearly this isn't the answer.
