[Beta2][Pinephone] Wake from sleep shows app contents before lock screen
SUMMARY
Waking Pinephone from sleep using the power button shows the previous screen state for a short moment before displaying the lock screen.
DETAILS
Clicking the Pinephone power switch after the phone is put to sleep using the power button with an app open (in my case, the Weather app) will wake the phone, but display the open app for a short duration (about a second) before the lock screen is then displayed.
EXPECTATION
Waking the phone should NEVER show app contents and always present the lock screen in a timely fashion.
REPRODUCTION
- Wake Pinephone and go to home screen
- Open Weather app
- Click power button to sleep Pinephone
- Wait a few seconds
- Click power button to wake Pinephone
- Observe that the Weather app is visible for a moment before the lock screen
SEVERITY
Major: This is a MAJOR privacy issue and potentially a security issue! App states should never be rendered or revealed unless the phone has been unlocked.
