Hello @Monicuzz A Warm Welcome to our friendly King Community!
I am sorry to hear that you have lost all your boosters in the game
Unfortunately, when we change our device, only the game will be transferred but not the boosters like Lollipops, etc., It is because the Boosters are stored to the Device Memory but not to the game like Gold Bars.
But, if you have not deleted the game from your old phone, then the boosters are still intact on your old phone and you can still play the game use them all
Hope this made sense! Please post back if you have more questions, by tapping on "Type your Comment" box located below.
Thank you for posting in the Community! Have a great rest of the day/evening!
