On my Ubuntu phone, I have set my screen lock to come on after a minute of none use. This is in the Settings > Security & Privacy > Locking & Unlocking. The lock does come on as requested however, it is instant. One second the screen is on and then the next the screen is locked and black. There is no fade (like on my Ubuntu tablet), which fades out giving me the option to cancel the locking, if you wish to.
Is there a setting that stops my phone from locking so fast and where I can increase the fade?
