Frequently Asked Questions

  1. Failed to pair
    A: 1.If you have installed mobile security APP such as Mobile Manager or Mobile Safe Assistant, this kind of APPs may have prohibited some permissions of Mangotek. Sometimes the system will even prompt security warning, thus it leads to a failed search. To solve it, please access to this kind of App, make Mangotek as your trusted App, enter the permission settings, set all Mangotek permissions to Allowed. 
    Your model is too far away from the router, take it closer and retry. 
    3.Check if the device has auto-exited pairing mode in the pairing process. 
    4.Try to pair with another Wi-Fi network. 
    5.Try to pair with another phone. 
    6.Switch off and on device, then try below:
    ① If your model’s pairing led fast steadily blinks. Please go to Phone Settings-->Wi-Fi, find the Wi-Fi starts with ITEAD ( ITEAD-10000XXXX), enter the password 12345678. If you failed to find ( ITEAD-10000XXXX) or when you enter the password, it says “Wrong Password”, your model has hardware problem, please contact seller for return & exchange. 
    ② If your model’s pairing led fast blinks 3 times and repeats. Please check if you have enabled “Wireless network internal isolation”. Enabling it will cause the App can’t access the device and failed to search the device. Please disable it. If still failed, please contact seller for return & exchange.

    ⑦ Firewall Settings 
    You may have opened firewall or some security software. In this case, please temporarily close them and try to re-add your device. 
    After making all above checks and find no problems but still failed, the possible problem should be DNS error. Please manually change DNS server address to 119.29.29.29. Then try to re-add your device.
