I don't know about "in-circuit", but this video shows how to use the XY mode of the Zeeweii to test components:

Given that, what is the compelling reason to buy this over the DSO3D12?

For my the major reason to buy it vs the DSO3D12 was the form factor, I already have a better oscilloscope and a better DMM so I just wanted an small and portable oscilloscope. In your case if you are not concerned about it's bigger size it may be a better option.

Thanks for the link. I watched this video. True, the serviceability of the parts is not determined in-circuit. There are several Russian videos about in-circuit determination of the serviceability of parts for the XY mode using a homemade attachment. But everywhere we talk about analog oscilloscopes. I wanted to find out whether it is possible to determine details using such a digital 2-channel device or not.

I'm not an expert, but I don't see why there should be a difference between digital and analog in this case. They just measure voltages.
The problem is probably more with the "stimulus" and the probes.
Perhaps an SMD tester like the Mastech MS8911 would be suitable?

I also think that there should be no difference between analog and two-channel digital in this regard. As for the Mastech MS8911, it is an ordinary multimeter made in a pliers form factor, and therefore it will not be able to determine parts in-circuit.
In a word, I purchased Zeeweii DSO2512G (V9.15). I liked it - a fairly high-quality device. But I had a couple of questions: 1) What does “RTAuto” mean in the upper right corner of the screen, which appears when you long press the Auto button.
P.S. I wanted to send images of my board and "RTAuto", but I couldn't. How can I send an image here when replying to a post?
