Lumia 640 XL can capture up to 1080p resolution videos and resulting video samples have good details, punchy colors and look good when you keep your hand steady. The lack of OIS again makes itself felt here. You can check for yourself in the video samples above. Even in low-light it can capture good videos, if you have steady pair of hands even without flash thanks to its F/2.0 aperture. The Lumia 640 XL lacks digital video stabilization but with Windows 10 Mobile that may change.
