Not sure if it fits here, but I found no community that distinctly focuses on phone repair/data extraction. I hope this is fine.

Recently, my phone's display died. I am trying to save the data.

I bought a more advanced OTG hub that should allow connecting the mouse and an external display. It also has a USB-C power input so the phone doesn’t have to power everything itself. The phone is connected to the hub via USB-C as well.

However, I haven’t even managed to get that setup working with my current phone (CMF Phone 2 Pro). I enabled the “Improve OTG Compatibility” option, but the hub still doesn’t appear to work, even though it’s advertised as being compatible with smartphones and other OTG devices: https://www.amazon.com/dp/B0GD7G9HS9

At this point I’m unsure whether the problem is me, the adapter, or possibly an issue with the display I’m trying to use (though the display works fine with other devices).

Any ideas? If OTG is not the right way, I am open for other suggestions. I am not really interested in repairing the phone, I just need the data.

EDIT Why Otg?: I thought of OTG for data extraction, because attaching a display and a mouse should enable me to use the phone again assuming that it is just the display that is broken. In order to verify my correct OTG setup, I attempted it first with my working phone which did not work.
