Galaxy S9 touchscreen issues This doesn’t appear to be a widespread problem as only a small group of users have complained about it. The vast majority of customers who picked up Samsung’s new flagship have not experienced any Galaxy S9 touchscreen issues. On a device that’s almost all touchscreen on the front and keeping in mind that it’s the only way to interact with it, you would obviously want the touchscreen to work without any issues whatsoever. Some Galaxy S9 and Galaxy S9+ users have complained about dead spots on their units, the term “dead spots” refers to sections of the display where touch input is either ignored or not registered, to begin with. Most of the reports about these dead spots have been about the Galaxy S9+.
