This is an over ambitious idea that is such a fudge that Samsung are trying to push down our through. Based on incomplete technology the Galaxy Fold is an expensive toy that will brake soon after use if it has not already been delivered broken that ours was. Keep in mind that if you apply any pressure to the hinge mechanism it will break or have a slight play that will break over time. the screen size if out of ratio and will not fit any media size. you cannot put a movie on full screen without cropping half of it or take a photo without cutting the edges. The sound quality is good and the battery is also good but that is now expected from any high end device. The phone is bulky and staff keeps getting stuck on the empty space between the screens when folded. Maybe in 10 years it will be a viable device but today save your £1,800 and go for a nice holiday or buy yourself a second hand BMW Z4 because they cost about the same thing! To sum things up this phone is simply a stupid idea!
