You can buy 4K movies from various online platforms like Amazon, Netflix, or Vudu. Once purchased, you can download the movies for offline viewing. However, due to DRM and copyright policies, you can't save the downloaded files directly to your device and can only watch them within the streaming service's app. To get around this, I've been using StreamFox for video for the past five months, and with its 99% download success rate, I can easily download HD videos, up to 4K, in MP4, MKV, or MOV formats. This allows me to store the files on my device. From there, it's up to me whether I want to transfer them to my SD card or another device, so I can watch them anytime, anywhere, without an internet connection.
