Why doesn't the mobile phone vibrate as soon as it has information?

There may be the following reasons: ① The mobile phone suddenly vibrates but there is no information. It may be that the message notification bar of the mobile phone is closed, and the push message will not be displayed when it comes back, but there will be a prompt tone. ② There is no information when the mobile phone vibrates. It is also possible that the SMS management software intercepted the SMS, so the SMS number was intercepted in the blacklist of this software, so it was not displayed. (3) Cell phone vibration is not caused by SMS. Setting vibration in settings, including software message reminder, system message reminder and many other aspects, will have vibration and breathing light reminder. ④ Sometimes the vibration may be triggered by the system, so it will not be reflected in the form of messages.

(Note: If the mobile phone vibrates frequently, there may be something wrong with it. You can take your mobile phone to the after-sales service center for testing. )
