Michael Fisher, a videographer of mobile tech, tweeted out his disappointment that a tiny, foreign object had found its way into his review unit, disrupting the screen's function. An escalating list of issues has prompted the world's largest phone maker to.
"Sigh. A little grain of something found its way beneath my Galaxy Fold display," Fisher tweeted Tuesday afternoon. "Sending this back to Samsung hoping they figure out a way to seal up that hinge."
Fisher said he would post a video demonstrating the issue affecting his unit on Wednesday.
Samsung didn't immediately respond to a request for comment.
Samsung's woes began last week when four early production review units. Those screen issues eclipsed other customer worries about long-term wear and tear on the seam or creases where the phone, with its 7.3-inch screen, bends in half.
The incidents with the Fold's plastic screen -- which include a screen bulge and flickering display -- have caused a, casting doubt on the durability of Samsung's $2,000 foldable phone and on the concept of bendable devices in general.
