post-safemodecheck: clarify that just the camera app needs to work

[lifehackerhansol]

• It is not uncommon for users to have a broken camera
• In this case, camera app will try to load and then crash, which implies that shoulder buttons do work
• Let's make life easier for these users

Couldn't we just word this as "If the screen changes" or something? I feel like people will see the but crashed thing and then think that implies that it won't work
