If you got a strange OnePlus 7 Pro push notification on Monday, you're not alone. Owners of the Chinese phones rushed to Twitter to express their concerns over a pair of garbled messages -- one of which appeared to be Chinese characters and other in the Latin alphabet.
Trying to follow the link apparently resulted in a "browser not found" message. The issue is seemingly only affecting the OnePlus 7 Pro, which came out in May.
"During an internal test, our OxygenOS team accidentally sent out a global push notification to some OnePlus 7 Pro owners," the company wrote in response.
Its team is investigating what happened and the company promised to share more details "soon."

OxygenOS is a customized version of Android developed by OnePlus and the odd notification caused some people to worry about the security of their data, harking back to a 2017 incident where a security researcher found that personal data was being sent to OnePlus servers.
It responded by explaining how people could opt out of data collection and promised to stop gathering data like "telephone numbers, MAC addresses and Wi-Fi information."
