New 2ch pocket DSO+SG - Zeeweii DSO2512G

can't save XY mode

Neither can its close relative, the Zeeweii DSO3D12.

True.
With an AV capture card you can take a screenshot on the PC.
However, the image is slightly blurred.

I got the same issue but in my case it was my fault. I overloaded by high voltage input 1 of DSO2512. I had to replace GS8091 opamp which I found on aliexpress ($4 for 5 pieces of GS8091 including shipment).
Temporarily you can use 8091 removed from signal generator circuit.

Many thanks to @timschuerewegen and his discord
Now I am happy user of hw ver9.14 and his 1.3.0c mod

Hello, does the subject have a digital zoom function and an external trigger?

digital zoom: Yes
external trigger: No, I think that's rather rare with cheap handheld oscilloscopes.

It seems that at best this scope is just a DSO3D12 without the DMM built in, a smaller screen and missing a few minor features and is yet only about $9 less.

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

The two are very similar, but the DSO2512G has at least two advantages:
- It has a video output, which I find very handy for recording videos without a camera and/or enlarging the small screen with a monitor.
- It has a 10MHz (sine wave) signal generator vs. 2MHz on the DSO3D12.
- It also has a rubbery holster and is a little smaller afaics. You can put it on the air filter of a running car engine without hesitation. It wouldn't fall off.

Maybe there are more differences.

Well that video out is a clear advantage.

The generator on the DSO3D12 will do 5MHz sine, 2MHz everything else.  But, 10MHz is a bit better.

Thanks.

I'm interested in a couple more questions.  First: Is it possible to use xy-mode to determine the in-circuit health of components, as an analog oscilloscope can do with the help of a small add-on?

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

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.
