What to do when Bluetooth or Wi-Fi connection is unstable on my Galaxy Z Flip?

Last Update Date : Feb 25. 2020

Unlike ordinary smartphones, your Galaxy Z Flip is specially designed to fold downward. Based on this new feature of the Samsung foldable device, you can hold the entire folded device which can affect radio waves such as Bluetooth, Wi-Fi, and other networks. 

Check the following situations first

It is recommended that the user uses the device with the product cover supplied to avoid direct hand contact with the antenna.
