Ask about DSO1202B

CYH2018

Hi,
I have two of his hand measurament instruments.
I am happy with both of them, DSO1202B and 2D72
Now I have a question about DSO1202B, it is one of the first units that
went on sale.
I had never updated to the latest version and recently did so.
I thought maybe I would find some improvement, but I found a problem.
It is possible to select three colors, blue, purple or green for the
multimeter (DMM) interface.
After the update, dso1kb_2.01.1_DSO1202B(190806.0)
It does not save the choice of DMM interface color when I turn it off
the device and when I turn it on starts in purple.
How do I ensure that the selected color, for example blue, is remembered
when the device is turned on again?
Photos and video are attached.

Dear Sir,

Greeting from Hantek.

The color of the multimeter function of this device cannot be recorded, and it is the default setting after startup

Have a nice day.

Jose

I think that what you say is not entirely true.
Before the update I don't remember that you could select another color for the DMM display and it was always light blue.
Now when turned on it appears a very unpleasant purple color.I find the light blue color more friendly.
How can I reload the previous version?
Thank you
