Now before you go ahead and lambast Apple and their hardware, apparently it seems that hardware isn’t the issue here, but rather Apple has not allowed that feature on their phones yet. This is thanks to an interesting discovery made by the developers of WALTR, a Mac app that lets users drag and drop video files from their computers onto their iPhone that aren’t supported by iTunes, such as FLAC and MKV-based files for example.
It seems that during the testing of the app, it was discovered that the iPhone is actually able to playback 4K videos on the phone itself, even if Apple might not necessarily have announced it themselves. It is unclear as to why Apple might have disabled the feature, but if you have some 4K videos you’d like to test on your new iPhone 6 or 6 Plus, you should check out the WALTR app although a lifetime license will set you back $29.95.
