Mass mailing on OnePlus 7 Pro smartphones

Users of the flagship OnePlus 7 Pro worldwide were worried when incomprehensible Push-notifications with text consisting of a mixture of Latin letters and hieroglyphs began to arrive on their devices. And when you click on this message, nothing happened, and the system informed that "the browser was not found." Numerous subject forums and official company accounts quickly filled with complaints.
To the credit of the manufacturer, he very soon published a statement explaining the reason for the appearance of this mysterious Push-notification. It turns out that in the process of testing OxygenOS, developers inadvertently sent a test message to all users of OnePlus 7 Pro. The company apologized for the inconvenience and promised that the error will be eliminated very soon.
