I’m a Software Instructor and Mac Consultant – not an iPhone expert, so I was pleased to find an answer to a question today.
I have a 16GB iPhone 4, which has quite a lot of apps, music, video, photos and books on it. So, I’d expect to have a lot of space used on my phone. However, even with all this stuff, I was losing storage space to a “little item” called “Other” in my iTunes view of my phone – I was losing 2.6GB of space!!
I knew I could restore from a backup, but I’d just spent quite a bit of time clearing some photos and didn’t really want to spend an hour restoring from backup.
Fortunately, I found a very simple solution that worked perfectly:
On the iPhone, Go To “Settings/General/Usage/Music and then swipe left to right over the “All Music” entry and select Delete, then re-boot the iPhone.” He stated, ” you think it would delete all your music, but id doesn’t” (sic)
