Got dust on my G5 16mp camera sensor, anyone ever cleaned camera sensor on phone?

I keep my phone super clean and always protected. Yet, unlucky me, I got dust on the camera sensor. Last week a dark spot started to show on my photos.. it usually shows when the background is something bright like sky.
I guess I need to take it apart and spray some compressed air on the camera but I was wondering if I need to really open the camera module..

:confused:

Thanks
