Hi @sultanks and welcome to our adorable Community 😊 You can easily save your progress by connecting your game with a Facebook or a King account. This way when you download the game on your new phone you can just log in with one of those accounts and your progress will be there.
There is also a way to sync your progress between Facebook and King account. You can see how to do it on the link below.
Please note that the boosters you collect are saved on your device's memory. If you change the device or reinstall the game, you will lose all of them. You can always use them on your old device before installing the game on the one.
Thank you for your understanding. Good luck and keep crushing 🍭
