If you’re like most iPhone users, you probably watch a lot of videos downloaded from the internet. But how do you watch them on your iPhone? There are a few different ways to watch downloaded videos on your iPhone. The easiest way is to open the video in the app that you downloaded it from. For example, if you downloaded the video from YouTube, open YouTube and click on the video. If the video isn’t in an app, you can try watching it online. Open Safari and go to the website where the video was originally uploaded. Click on the link for the video and it will open in a new window or tab on your computer. If neither of those work, you can try using an app called AirPlay Mirroring to watch videos on your iPhone. AirPlay Mirroring lets you wirelessly send videos from your Mac or PC to your TV set or other Apple device like an iPad or iPod Touch. Just make sure that both devices have AirPlay enabled and that the videos are compatible with each other. Then just start playing the video on one device and mirror it to another by pressing and holding down one of the AirPlay buttons on each device until they both turn blue (or press Control-Option-M). ..
