Smartphone does a restart after clicking next title

[derolli92]

Hello everyone ( I'm German, so I hope you understand my problem),

i have a "Huawei Ascend P2" Smartphone and use Spotify Premium. Evertyhing works well...i can play the music everywhre with the download of the playlists...but sometimes I get the Problem that when i press the button for next title...doesn't matter if i do that on de smartphone media player app or at the spotify app or at my headphones...the phone takes a restart. It's only at the Spotify app. Does anyone know the Problem? If there is someone from Germy or sth you can also write it in german. 
thanks
