iPhone Storage Problem
I have an iPhone 4s 8gb. Storage available 399mb Capacity 5.4gb Version 8.3 (12f70) I haven 0 songs, 1 video, 71 photos, and 10 applications. My brothers iPhone is a 4 8gb and he has over 350 songs, 50 videos, and over 120 songs but still has over 1gb of storage available. I can't take anymore videos or pictures because of this and probably can't add any songs at all. This all started about 9 months ago. I have had the phone a little over a year now. I can't afford to pay for a replacement through apple support. If someone could please help me, I would be so grateful!!
iPhone 4S, iOS 8.3
