Synchronization

Hi, I also have a problem regarding synchronization with devices (mobile phone and tablet).

my situation is as follows:

I don't have Facebook

I used candy crush saga for the first time from my phone.

I created a king account from the game and had to do it again on the site because it told me that the account didn't exist, in fact they have a different avatar image.

Now since I have to change my phone I would like not to lose the progress I have made, what can I do?

Thanks to everyone who will help me.
