This app worked perfectly on my old S6 and locked the screen without wearing out the power button. However on my new S9 it wouldn't activate the intelligent lock feature (facial+iris), and everytime I locked the screen using this app it would ask me for the pin instead when I try to unlock my phone. Hopefully there will be an update soon that fixes this.

this was my favorite app on my older Droid phone. But on the new pixel 3 it does not work as well. The animations do not work, with the exception of TV static. and the phone will often wake right after sleeping, even though I have selected delay in the preferences. if this app can be restored to full functionality on the new Google pixel 3, I would even be willing to pay for it.

In 2014 my Samsung Galaxy S4 developed an intermittent power button fault. Faced with a hefty repair bill, I tried this app. It has worked flawlessly, to the extent that I never even think about it, let alone rating it. The phone has not been repaired, and is still going strong! When I do replace it, I will install this app immediately on the new phone. RECOMMENDED. UPDATE: A clear indication these guys are on the right track; my S4 finally died... My new phone (Oppo Reno Z) has this built in!
