I'll just clear up the basics before proceeding as previous comments have just been talking about things that really haven't helped me get any closer to fixing this.
Have I checked out the broken screen tag wiki?
Yes, filled with circumstantial answers that didn't really make any sense to me, every answer required something I couldn't do.
Use a USB-OTG cable?
Unfortunately the screen is untouchable. I can't see what I'm doing so I wouldn't be able to direct a mouse even if I could get one connected.
Basically, I have a Samsung Galaxy with a broken screen, touch screen also broke and USB debugging is disabled, can I still save this?
I just wanna be able to control it for a little before taking it to a store. I need to do some things, is this possible? Every answer I read just talks about circumstancials.
I actually might have USB debugging enabled, although my device isn't showing up when typing
adb devices and simply prints
List of devices attached with 2 blank lines after it.
