@Kelvin228 Hi and welcome,
Your Boosters are stored on the device itself, so if you format your phone you will lose any boosters you have collected in the game. you could check google to see if there any known ways, like iphone you can back up to the cloud and restore you game from that and it can keep your boosters
I use mobile and the Windows 10 version. I had to reinstall the Win 10 version and lost everything. I contacted support. I had taken a screenshot of all my boosters before reinstalling. They asked me to send them the screenshot of my booster count and they did give me back the boosters I lost from reinstalling. Maybe they can do the same for you on mobile if you take a screenshot. It can't hurt to contact support and ask them. They were really nice and helpful when I contacted them or well, at least the person I spoke to. Good luck! So you might get your boosters back but your lives and stuff from the inbox will be gone so you would definitely have to start over with that.
