Compliant product. Please note, the manual is in Chinese and approximate English, with very few details. For experienced tamperers.

I bought it because it's cost-effective and can be connected to TVs or monitors that don't support mirroring.
For the S20+ and S24 Plus, it connects just by plugging in the cable, but it doesn't charge in the middle and it's very inconvenient to keep the screen on and not be able to do anything else.
This product is plugged into the HDMI port of the monitor or TV, connected the included cable or the micro 5-pin used for older smartphones, checked the power supply, and pressed the button. The screen immediately displayed.
When I turned on Smart View on the unused A32 in that state, it immediately mirrored.
And it's good that the output is proper even when the smartphone screen is off.
The downside is that the video looks like a frame-dropping screen, but considering the price, it's understandable.

It should be good

For photos, it's okay, but for streaming services like Netflix, Disney, Videoland, NPO, etc., it doesn't work. This does not provide an image due to decryption. I returned it. Unfortunately

Top for Samsung DEX.
