Stucked on SAMSUNG logo = brick ?

Hello, I received a new telephone two days ago, so I turned off my galaxy core and removed the sim card. For some reasons I had to use it back again, so I tried to turn it on, but surprise, now the Galaxy Core Prime is stucked on that SAMSUNG logo...

I precise that my phone is unflashed, and unrooted. Is that possible it got bricked... By itself ?

Thank you all in advance !
