This is physics after the x10 periscope zoom is maxed out it uses digital by cropping in and resizing the pixels.
Essentially it is like when you use zoom tool in photoshop on an area until the tiny pixels become larger blocks.
If you use a larger pixels and the same resolution then the results are typically better as, more light us captured on to the sensor.
However all is not lost, you can buy a field scope or telescope with tripod/adapter and use the range of that to enhance what you are viewing and photographing.
Whilst the pixel imaging won't be dramatically fixed, the focal range and use of glass optics will improve overall.
Especially if you like to photograph hard to reach places or small birds. Another thing that reduces detail is the F stop for the lens. It is stated at F4.9 which is an equivalent of well over F22 on a full frame camera. Or lesser when compared to a 1 inch sensor however at just under a 1/3 of that that would be something like 8 times smaller.
Anyway the point is, if Samsung decided to fit a motorised lens with more room to move then you could achieve cleaner shots.
But I know nothing as Manuel from fawlty towers would say.
