Dear @odifoke,

For the growing cyber attacks and hacking behaviors, we have launched the AiShield feature to strengthen the protection of the home network, especially to inform the users of this good news (one month free trial service) by pushing message. If there is any inconvenience, please kindly bear with us.

In addition, the vibration part can be turned off on the setting of your mobile phone (This is depending on the design of the mobile phone). 

Below link is the information of the AiShield feature for more understanding.

If you have any suggestion, please feel free to let us know, thank you.

Have a nice day!
