I want to change my smartphone, is there any way to save/restore the Blynk app design or any other trick to move the design from smartphone A to smartphone B?
You have just to connect your new phone to blynk server and use the Auth you have used in your old phone.
The app design isn’t stored on the phone, its stored on the Blynk server.
When you install the Blynk app and log in with your Blynk username and password it will automatically show all of your current projects.
You can use multiple phones at the same time with the same Blynk account if you wish.
Ok thank you for this information
