Seriously still NO way to easily lock your blackberry 10 device?
I know we can press and hold the power button on top and then select "Lock" to immediately lock your device. This is very frustrating for many people including me.
Why Blackberry can't include this option like other smartphones do? Many situations that we may want to lock the phone immediately, such as:
1) quickly away from your desk for a while and don't want to carry your phone, but you want to make sure your phone locked before you leave; yes, press and hold the top power button waste too much time.
2) when someone show up unexpectedly, and you want your phone locked immediately so that you don't need to worry your phone still unlock.
3) Just want a quick lock button / shortcut!!!

Wrong. Theoretically it may take 1 or 2 seconds to password lock the device, but in real world it will take over 3 seconds at least...
Try it yourself. You're not always put your finger on the lock button and fully ready to lock your device. Most of the time you are with an app or doing something, you will have to move your hand up from the center of the screen and press and hold it for a while (don't say only hold it 0.5 seconds, in real world you won't try to time that, you will keep holding it until you see the lock icon shown up), then you move your hand back to the screen again and press the lock icon....
The real problem is: it requires your attention to password lock your device instead of just a simple click on the button.
Btw, I am not satisfied with the K key solution as you claimed I do.
Although the K key can lock your device, you need to swipe up / exit from app and return to your home screen first. If not, the K key won't work. Why argue so much on this? A simple option in setting will sure make everyone happy.
