Samsung has started the promo campaign for the Galaxy M30s, but the phone isn't quite ready for hands-on videos. But that didn't stop this particular video from hitting YouTube - a quick 5 minute tour through the phone. Interestingly, the redesigned triple camera on the back seems to have an extra sensor - Laser autofocus, perhaps (it's certainly not a 3D ToF sensor like the big Galaxys have). You can see it at around 3:10 in the video (we also have a screenshot below). This triple camera will use a 48MP sensor, quite an improvement over the 13MP sensor in the vanilla Galaxy M30....
