The Wall Street Journal released a video that seems to mock Samsung Electronics' Galaxy S10 5G overheats problem. The person who posted the video was a WSJ's IT reporter Joanna Stern who twisted the performance of Samsung's Galaxy fold in a similar way three months ago.
Joanna Stern pointed out that while testing the 5G service in major U.S. cities on July 19, the 5G network was changed to 4G due to overheating of phone. In Atlanta and New York, the product changed to a 4G signal as it got hot, and in Chicago, downloading Netflix files took time until sunset.
In Atlanta, where the temperature was 90 degrees Fahrenheit (32 degrees Celsius) at the time of the shooting, the smartphone instantly changed to a 4G LTE signal as the smartphone got hot, and the download was delayed in Chicago, where the temperature was similar. A similar situation took place in New York, where the temperature was 83 degrees Fahrenheit (28 degrees Celsius), Stern added.
In a video clip that lasted less than five minutes, there was also a scene in which the Galaxy S10 5G was put into an ice box to lower the temperature.
But the problems that Stern point out was revealed to be caused by 5G coverage (serviceable areas) in the U.S. It is known to have nothing to do with defects in the products.
"The overheating issue happens because there is not enough network coverage for the 5G service," Samsung Electronics said. "We saw the same issue when 4G service was launched. When there is not enough network coverage for the latest network service, these kinds of issues always happen."
Currently, base stations are being expanded in South Korea and the U.S. to supply 5G. Regarding WSJ's video, Samsung Electronics explained "processors consume more energy because large amount of data is transmitted at a fast rate when 5G is turned on." It also said, "when temperature reaches certain values, it will convert to 4G in order to minimize energy use and optimize batteries."
Meanwhile, Stern compared Samsung Electronics's Galaxy fold with paper, scarves and folding chairs in the video in April, saying the Galaxy fold should not be folded. Stern was also criticized for acting more like ridicule, not criticism, with scenes such as putting hot dogs in a product.
Much of what she has raised has nothing to do with the flaws in the Galaxy fold, prompting criticism that a professional ICT media reporter is only making too much of a mockery.
