G900F Marshmallow no quick params

Hello !
Please excuse my bad english
I'll expose you my problem :
Since I updated my G900F to Android 6 (via OTA), the quick params toolbar have disappeared. I don't know why, and how to put it back, so if you have an idea...
When I reboot I have a pop up "seetings have crashed"
Thank you !
