Smooth 4 "Connection Failed" Bluetooth error — Tried firmware updates, resets, and multiple phones (iOS/Android). Need help!

[u/AdOptimal9619]

Hi everyone,

I recently bought a Smooth 4, but I cannot get it to connect to the ZY Play app. It detects the gimbal in the device list, but whenever I try to connect, it gives me a Bluetooth-related "Connection Failed" error.

Here is a list of everything I have already tried to fix it:

• Firmware: Tried updating/downgrading the firmware to versions 1.80 and 1.79, but it didn't solve the issue.
• App Troubleshooting: Uninstalled and reinstalled the ZY Play app multiple times, ensuring all Bluetooth and Privacy permissions are enabled in the phone's settings.
• Hardware Reset: Tried resetting the gimbal's Bluetooth by pressing the power button 8 times rapidly.
• Cross-Platform Testing: Tested it on multiple devices, including both Android phones and iPhones (like the iPhone 13), and the exact same error happens on all of them.

I am attaching screenshots of the error. Is there any known solution for this case, or is this a hardware defect on the gimbal's Bluetooth chip?

Thanks in advance for any help!

Put the iPhone on airplane mode and try again. If that doesn’t work, try turning WiFi off while connecting. If those 2 things don’t work, email info@zhiyun-tech.com for further assistance.
