The updated Moto X is an Android phone with a gorgeous display, chic design, solid performance and efficient voice comments, all at an accessible price.
Yes richkar1127 it does work that way, and it actually is able to do that anytime, whether the phone is asleep or in any app, it's actually one of my favorite features honestly.
Will it allow you to write on the screen similar to a Note III.
No, the Note series has syluses that a specifically made for that. Sure, you should be able to get apps that draw, but it will be a far cry of the drawing experience on a Note III.
Why do you need to have a lockscreen button for the camera? Doesnt camera work if you twist the phone like the original moto x?
It's part of Android. Every phone that uses the stock Android lock screen has that, and taking it away would make no sense. Both will work, and you are free to choose whatever is most convenient for you in the moment.
