Unlock problems after some time of inactivty

[IoanAndrei]

Hello guys,

In the last couple of days I noticed something strange about my Samsung Watch.
After I take it off or after some time of inactivity, the screen won't turn on if I make a wrist move or even if I double tap the screen. The only I can turn it on is by pressing the home button.

This is a normal thing and I didn't noticed it yet ( 6 months...I hope I'm not an ***** :)) ), it came with an update or I have a problem with my watch?
