I totally agree, 100%.
This is, in fact, my biggest and only problem with this phone. I use my phone on my desk throughout my entire work day, and most of my time at home as well (coffee table, etc).
I've heard all of the alternative solutions, but I don't like them.
- Use face lock. No. It can be fooled by a photo of me, not secure.
-Iris scanner. Sure, but then I need to pick up/position my phone each time, really not ideal.
-Smart unlock to my WiFi or watch. Still not good enough, it needs to be locked. I have a 2 year old, I rest my case. (no, I don't intentionally leave it where he can reach it, but life happens).
-PIN/password. Perhaps, but an extra step that was simplified by the invention of fingerprint reader, haha.
The one saving grace is that, coming from the S6, I'll now have the always-on screen to show any notifications.
I may invest in a wireless charging stand, rather than the current wireless charger I use that's flat on desk. That way, perhaps I can angle the phone at my face for Iris scanning while at work.
