E-Tube Cyclist mobile app doesn't start on Android phones
When Shimano updated the E-Tube Cyclist mobile app for Android and iOS in 2022, they changed a bunch of things.
As a result, the E-Tube Cyclist app will not start properly on Android phones when USB debugging is enabled. If your E-Tube mobile app doesn't start, double-check to make sure USB debugging is disabled.
For more information, see the Android page on USB debugging.
