I noticed that my 955 Solar screen shows little "points" like a grid all over the screen. In this photo they are visible only in part cause backlight effect. The points are all aligned like a "grid". Does anyone noticed this thing?

They're on the non-solar version too. Definitely something touchscreen related. Reminds me of old Casio calculators.
If you look at any phone screen at the right angle, you'll see this sort of pattern too. It's the transparent conductive grid for the capacitive sensor.
It's usually made of ITO: en.wikipedia…
