Why does the Honor Hongmeng system vibrate at 12 o'clock every night?

It may be a time reminder for events and memos. Close other applications and give it a try. Just turn off notifications. Then the calendar just vibrated. Huawei phones often have problems after updating the Hongmeng system. Because the Hongmeng system is a new system, there will be many bugs. The official will slowly release new patches to repair it in the future.

Why do I turn off the vibration of app notifications, and turn on silent notifications but don’t know there are notifications? Just don't want it to vibrate.

Although there are Glory, there are not many of them. Therefore, I think it is not entirely correct to attribute the high popularity of Huawei Hongmeng to the young group. It may be more appropriate to attribute the huge fan base of Huawei mobile phones. There is another point that I think is also very important.
