I definitely enjoy the daily videos as opposed to a video dump.
Many 360p videos have very crisp sound. Is there a way to make the sound less muffled while keeping a low file size?
Also, you might be able to use Wifi to make calls if you enable Wifi calling on the iPhone (it’s disabled by default).
Video and sound quality are likely impacted by how you choose to record and encode it. To keep the size down of a file at a certain format, you lose some of that clarity. I’d be willing to bet the 1080p video will sound just fine once he switches them out.
