Game freezing Solution

For nearly one and a half years the game was freezing. Every 10 seconds without exaggeration. Then recently it was every 3 seconds. I was ready to give up. 

I then found a solution. 

Making sure I copied my game ID number and strong connection, game backed up, I deleted the game from my phone. I then reinstalled it. 

The game went from 4 gig to 600 mb.
It amplified even more new storage on my phone.

My game is now playing lightning fast. 

I’ve been playing nearly a decade. It accumulated a lot of files on my phone. I’m not familiar with the technical details. This was the cause. Perhaps it can help you guys too.
