Samsung is investigating Galaxy S9/S9+ "dead" spot touchscreen issues

The majority of complaints about this issue have been submitted by owners of the Galaxy S9+, although reports of the same problem happening on the Galaxy S9 have also been recorded. There is no particular pattern to where dead spots appear on either device, with owners complaining about problematic areas in different parts of the screen, such as the sides and towards the center.
Following a number of reports on Samsung's community forums, the company has now issued a statement to Engadget that it is "looking into a limited number of reports" regarding the issue:
At Samsung, customer satisfaction is core to our business and we aim to deliver the best possible experience. We are looking into a limited number of reports of Galaxy S9/S9+ touchscreen responsiveness issues. We are working with affected customers and investigating.
We encourage any customer with questions to contact us directly at 1-800-SAMSUNG.
