I know this topic comes up all the time- I have had this issue from time to time on various iphones in the house and have always been able to solve it- but this time I am stumped- My daughter's 4s has over 4 GB of other, which equates to almost 1/3 of her free space. But on her phone, I have not been able to reduce the "other" amount. She even got her phone replaced last week due to a bad lock button- I restored from backup, and the 4GB showed up again, which to me meant that the problem was in the backup we used to restore. So what I did was delete all photos and videos from her camera roll (she had a ton), then removed all apps and music, and unchecked the sync buttons so that I could do a sync and backup and have ZERO photos, apps and music on the phone. Also turned off mail, deleted voice mail, cleared safari cache, deleted all texts, etc, etc. I then did one more sync and backup, and pretty much had nothing on the phone whatsoever. Then I restored from that backup, thinking surely that would at least reduce the other amount. But it didn't- when the restore was complete, the 4 GB of other returned, even though there was no data, no apps, no music, and no photos on the phone. At this point I am stumped- the only thing I have not tried is restore as new phone, which I don't want to do but may have to. I just don't understand why its still there after I took everything off the phone..... Anyone have any ideas?????
