How To Verify Original iPhone By Checking Built-in Applications
Every iPhone comes with built-in applications like calculator, music, photos, setting etc. If you get any of these applications missing then it may be not genuine. Some merchants sell the iPhone that is jailbroken. Then there will be no built-in applications that comes with original iOS. To be sure you can try to restore the original firmware and if built-in applications are still not appearing then it’s definitely fake.
