Possible Reasons Why iPhone Shows 0 Byte Error

Your iPhone may show 0 byte available storage error due to following reasons:

2. iPhone system is crashing due to some reasons, which lead the iPhone to show 0 byte space. In this situation, you may resolve the problem by restarting the device.
3. iPhone is infected with virus after jailbreak or other reasons.
