Default wallpaper image is smaller than the device's screen when unlocking it
Summary
If you lock the device (the screen turns off) and then unlock it (the screen turns on), the default wallpaper image is smaller than the device's screen and after the device unlocking process is completed, the image is resized to fill the entire screen.
However, if you use an app to place a wallpaper image, when you unlock the device's screen, that image will be seen correctly (filling the entire screen) throughout the process.
The problem
Steps to reproduce
- lock the device (the screen turns off)
- unlock the device (the screen turns on)
What actually happens
Throughout the process of unlocking the device, the default wallpaper image is smaller than the device's screen and after the device unlocking process is completed, the image is resized to fill the entire screen.
What you should see instead
Throughout the process of unlocking the device, the wallpaper image should fill the entire screen, just as it is when the device is unlocked.
