I accidentally found out that on my galaxy s4 I9500 lock screen, I can still press and hold power button and it gives me options to power off/restart my phone. I have pattern lock enabled. I tried and successfully powered off the phone straight from my lock screen, not to mention that it scared me out. What if it gets stolen? Anybody can turn if off and I wont be able to track it down or enable any thing via SMS commands etc.
What's the purpose of lock screen if the phone can be turned off, if not unlocked, and I couldn't do anything about it.
I recently updated android 4.4 and I am not sure whether or not this issue persisted before that. I am attaching a screenshot of it. Looking forward for someone to sort this out for me. Thanks.
