In the realm of cutting-edge technology, the Samsung S21 stands out as a flagship smartphone, renowned for its sleek design, stunning display, and powerful performance. However, some users may encounter an unexpected issue — a perplexing black circle appearing on the screen. This article delves deep into understanding this phenomenon, exploring its causes, implications, and potential solutions.
Understanding the Samsung S21’s Display Technology
To comprehend the black circle issue on the Samsung S21, it’s essential to first understand the device’s display technology.
