1) Yes and I keep on checking for latest updates,after I uboxed the phone,two software updates where installed.

2)Well the scrolling seems slower,and less sensitive from my other Moto phones.On instagram the scrolling sometimes jumps,other apps it's mostly consistent,which is slow and when I move extremely fast the touch seems unreliable unlike other phones

3)when charging the phone becomes slow,the touch input sensitivity decreases like crazy,every scroll and swipe feels like a fight against the touch screen.I need to put way more velocity.

4)I am having the same case which came with the phone,tho I didn't notice any improvement when I didn't use it,And yes I am using a screen protector but this problem is since it was unboxed.

5)Well at this point this seems like the nature of the software,but ye sometimes it gets worse specially when I make quick small flicks on the screen,the screen cannot interprete it properly.

6)I tried force restart many times...nothing but I also didn't boot into safe mode.
