How To Use OTG For Data Extraction?

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: 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 i

That is not really „OTG“.

The question here is, does your phone have USB3? Does it have display out over usb? Most phones do not, or they only have usb2. In that case I guess your approach will not work…

Have you tried connecting your phone to a pc to get data off in that way?

Thanks for the ideas!

I have edited in "Why Otg?" now:

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.

I also clarified that the phone is connected to the hub via usb-c in case that lead you down the USB3-USB2 path.

I tried connecting my phone to the PC and tried a software that should stream the screen, but this didn't work because it needs confirmation from the phone through a pop up and this is not possible due to the broken screen. I have not tried other software yet. Just by plugging it in will not work, because I cannot accept the connection for data transfer (also a pop up).

Again: are you positive that your phone is actually capable of display output over usb C? Just because it is USB C does not mean it supports that.

I am not 100% sure. I know that they are OTG compatible, but I am not 100% certain that they allow display output. Quick searches confirm the OTG, but don't mention the display out.

That usual PC to Phone connection is a networking protocol, most likely MTP to be more specific, so OTG won't help.

MPT should by default depend on you having access to your phone display for allowing the connection tho, so that probably won't do.

Your best bet would then be ADB, with which you can access your phone with your computer's terminal thru USB. However, that would need you to enable the setting, which would need your access to your phone's system settings. Not sure if there are other ways to enable this...
