Njx30 same exact issue here. When i swipe it leaves marks/ shadows. As an example when i swipe down to open the quick settings menu, the icons for wifi / bluethooth / vibration exc moves down as expected but in their original positions i get a duplicate, like a shadow of them and it looks reaaaally bad. Very bad quality it seems or bad quality control. It’s funny because in a video, the CEO was saying how much it is important to give a good first impression because otherwise the customer will not trust you anymore. These weren’t the exact same words cause i saw this time ago, but this was the concept, you can check it for yourself, and then we get this….. wow, nice. I really wanted to give nothing a try and was very happy to do it, but other than the OS which i really like how it looks and works, the rest is very bad quality, bad display colors very washed out, bad camera, impossible to take a realistic picture. Very sorry to say this. Hope they improve in this areas and then the device will be 100% worth but now it’s just disappointing and below the standard imo.
