The update determined that my problem was caused by a faulty display. I use it every day for about 3 hours without any problems on the second display. So my phone only works when I plug it into power (for reference I'm using S20+) for screen mirroring, and when I want to use Dex I plug power into the Type-C input, it's the reverse of what is written on the monitor. Hopefully it won't damage anything in the long run. If any manufacturer sees this please let me know. The touchscreen works great so far. I will give all updates
