Today, LetsGoDigital discovered such an improvement. The patent for ‘Electronic Devices Including Indicators’ filed in March 2019 shows that Samsung plans to add a series of indicator lights to the hidden hinge of the Samsung Galaxy Z Fold.

In this patent, a LED light is inserted under the translucent cover. These LED lights can combine different colors to achieve visual and decorative effects. We mean these LED lights can be used for new notifications, messages, missed calls, etc.

The patent was filed by Samsung in March 2019 and issued by WIPO (World Intellectual Property Organization) on October 1, 2020. It contains a total of 44 pages of patent documents.

This is because the yield rate is too low. However, this technology is now scheduled to come with Samsung’s next generation foldable phone, the Galaxy Z Fold 3.

So customers are more eagerly waiting for this technology to appear on a more popular brand smartphone. In this sense, Samsung, Xiaomi, and Huawei are the most possible variants. And now, there is every reason to think the Galaxy Z Fold 3 may come with it onboard.
