Frequently Asked Questions (FAQs)

1. Why does the smart bracelet automatically disconnect Bluetooth when the Android screen goes out?
2. Lock the background APP. When the JYouPro process is cleared, the smart bracelet will be disconnected from the mobile phone.
3. Set APP self-startup
4. Unrestricted background operation. The Android mobile phone installed with the APP intelligently restricts the background operation by default, and the App should be set manually without any restriction.
5. Why cannot the smart bracelet receive a message push?
6. Please confirm that you have turned on the switch for message push at the mobile phone client.
7. Please confirm that messages can be displayed normally in the mobile phone notification bar. The message push on the smart bracelet is completed by reading the message from the mobile phone notification bar. The smart bracelet will not receive the message push if there is no message in the mobile phone notification bar. (You need to find notification settings in the mobile phone settings, and turn on the notification switch of We Chat, QQ, call, SMS and mobile phone client).
8. Turn on the mobile phone – Settings. Enter “Notification use right” on the top search box, and re-open JYouPro.
9. Why can’t you take a hot shower or swim with a smart bracelet?
   • Answer: the bath water has a relatively high temperature, and generates a lot of vapour which is in the gas phase with a small molecular radius and can easily infiltrate into the smart bracelet from the shell gap. When the temperature drops down, the vapour will condense into liquid-phase droplets which will easily cause a short circuit inside the smart bracelet and damage the circuit board and then damage the smart bracelet.
10. Why is the Bluetooth connecting icon blinking all the time?
    • Answer: The user may encounter this problem. It mainly can prompt the users that the pushed message is not received if the APP is not connected to the bracelet.
    • Launch the APP to connect to the bracelet, and the Bluetooth icon can be displayed normally.
    • Note: For more frequently asked questions, please refer to the JYouPro APP User Manual
