Camera crashes on 120fps topic

LG default camera crashes when set on 120fps when I press the REC button it crashes to main screen with a BEEP.
I have the European version (D855 16gb memory 2 gb ram) bought it second hand with MyaROM v5.1 Lollipop and apparently no root access (I checked with Root Checker Basic).

Is the camera broken or could be the software?
