Same plays max at 1080p. Have to install DRM Info and check . I have heard the Mobile has to be registered with Netflix for them to give DRM clearance . I don't know if AmazonPrime video has the same policy
With proper lighting conditions, the pics are more or less the same. But you will find differences in the way colour, patterns, details are shown.
Will try to take some pics with both apps and post later.
Plays fine on phone, codec issue. Gcam saves the videos in H.265 format by default, just saw the setting. OPcam too has it but disabled by default. The videos are 4K 60 fps. Didn't get a Slo-mo sample, may be tomorrow.
