This issue can occur if you do not activate the Screen lock function (the function is set to NONE).
To avoid this, set the Screen lock function to SWIPE, or to use a PIN, Password, or Pattern as the unlock code.
Don't forget, similar to your phone, if you decide to use the Screen lock feature with something other than SWIPE (a PIN, Password, or Pattern), be very careful not to forget your unlock code. If you have forgotten the unlock code, you will not be able to unlock the screen by yourself. You will need to contact the nearest Sony dealer or Sony Service Center in order to get the device unlocked.
More information about the Screen lock feature is available in the Help Guide of your device, available on your product page on this support website.
