The next gen iPhone will have an A7 system-on-chip design with 1GB of LPDDR3 RAM. It is widely believed that Apple Inc.

Apple could also upgrade camera

Apple Inc. (NASDAQ:AAPL) will also make changes in its rear facing camera, iPhone 5S will use a larger F2.0 aperture lens assembly with dual LED flashes while sensor unit will be the same. Kuo maintained his previous forecast on the fingerprint sensor fixed in a sapphire glass home button.
