Thank you for participating in the One UI Beta Program.
To participate in the One UI Beta program, you need to agree to send diagnostic data at the subscription stage.
However, you can turn this setting off by following the path in Galaxy Wearable app : Watch settings > Watch information > Legal information > Sending diagnostic data to Samsung.
Even with this setting set as OFF, you can still keep and use Beta software, but we highly recommend to set it as ON, because the diagnostic data is only used for finding problem and improvement point of Beta software.
