Double camera is the newest trend among smartphones. Apple, Huawei, Xiaomi and many other companies already use those in their devices. There has been gossip about Samsung testing that technology as well. What is more, we have heard that Samsung has patented a new zoom function that allows the user to zoom the picture in and out with just one finger.
Even if Samsung is preparing new and interesting functions for his Galaxy S8, it is doubtful that the company will hasten its release. Koreans surely have the fiasco of their Note 7 model and its exploding battery on their mind, and will not risk releasing a flawed product.
