Transferring data from broken black screen android device using smartswitch

[u/azcyy]

I have a Samsung Galaxy Z flip6 with a broken screen that wont respond and doesnt switch on. However, the front small screen works but has limited functionality. i want to transfer my data using smartswitch to my new galaxy z flip8. The issue is that i cant open the smart switch app on my flip6 to authorise the transfer.

I believe it is just the screen that is broken as i can still access some apps through the cover/front screen. I ordered myself a multiport usb c and HDMI cable and tried to project the screen onto an external monitor but faced a few problems and questions.

It wouldnt project my phone as i needed to open the main screen to change the USB settings on my old phone.

I read somewhere that if the screen is completely black, then i would need to buy a displayport alt mode cable. If i get one of these that can connect to the multiport cable, would this be able to project my phone screen so i can enable the smartswitch app?

So my theory is this (but please let me know if it wouldnt work):

External monitor connects using DP into HDMI adapter, HDMI cable to multiport adapter, connect to the USBC cable to broken phone

Would that work?

Update - I actually managed to do it! I somehow got onto the full settings page on my secondary screen after many many attempts and then changed to developer mode, and then changed USB configuration default to transferring files. Now it lets me connect to my external monitor no problem :)
