Why game freezes on some devices? [phaser 2]

[arseniy]

Hello,

 

We made some nice game and it works fine on many devices, but as reported by one of sponsor it freezes on Galaxy S4 mini and Nokia Lumia 630

"- Game freezes after a short time. (Random) Happens while one or more projectiles are piercing the blops. (the game freezes the moment they are in the blobs center.)"

What might be the problem?

Here is the game:

Game made in phaser 2. Coder said to mention that objects are taken from pool/cache.

 

Thanks
