Oh dear, thanks so much for this, actually never noticed it's already present in Huawei, cheers Masteryates!
Xiaomi phones have this to... It's a widget if you have their os.. Miui os not Google one
What's wrong with just pressing the power button? (confused)
To people who have a Huawei/Honor phone, they have included this within the OS so no need to install an app like this. If you look at your Widgets, you will find a blue lock. Big up Huawei for this. For One Plus owners, in the settings you can turn on the ability to double tap the FP scanner to lock the screen.
Well hello there! Heat added for your choice of phone. (highfive)
