I have a brand new Samsung Galaxy S8+ (less than two months old) running the latest version of Android 7.0. Here is my problem:
When the screen/phone is lock and I unlock the phone/screen I am unable to use the phone; the phone does not respond to any of the icons that I touch on the phone; it appears that Touchwhiz is unresponsive. To temporary resolve the issue I have to lock the phone by pressing the power button to lock the phone. Then when I unlock the phone I am now able to access the icons, etc and use the phone. This is not an acceptable way for a $900 device that is less than three months old to work.
When I first unlock my phone I expect to use it IMMEDIATELY! I should not have to lock the phone manually then unlock it just to use the phone. In addition, pressing the power button that often will eventually wear out the power button there-by rendering the phone useless.
I have not done a master reset because I suspect if I do and then spend days re-configuring the device only to temporarily solve the issue then VZW might as send me a new device.
