We sincerely apologize for the two accidental notification push messages that some OnePlus 7 Pro users received 2 hours ago.
As soon as we noticed the mistake, we performed a round of in-depth investigations with the related teams to identify the cause. The push messages occurred while the OxygenOS team was conducting a software test for the upcoming Android Q system update. Due to an error during the testing process, we accidentally pushed a routine test message to some of our OnePlus 7 Pro OxygenOS users.
The notification push function is designed mainly as a survey tool to help us better understand our users’ feedback and to further improve the user experience, and is based on the Google FCM (Firebase Cloud Messaging) Protocol. Therefore, we want to reassure that this incident does not indicate any risks for your personal data.
We are immediately implementing new processes to ensure this cannot happen again.
Never Settle
