I have a Samsung S8+. I used to use a Samsung S10+. I exclusively use the provided cables. They rarely work now, 2 years on. Now, they never ever work. This screen has gotten more and more finicky and less reliable, the longer I've had it. This forum is absolutely lacking in helpful information as well. For the incredible amount of money this device costs, it is incredibly fragile and unreliable. Please provide support for the ports not receiving a signal. Some guidance at all.
