By turning off your phone then press volume + and power at the same time without releasing until phone boots up and wait for the recovery screen to show.
Then scroll down with your volume - key until you select clear cache then press the power button to do it.
When done just to be sure repeat clear cache.
After that in the same menu scroll down again o fix apps (I think is at the very bottom then let it do it's thing and it should reboot .
After that go in the galaxy store and download Good Guardians
