iPhone says 0 bytes available storage? This post from MiniTool will show you how to solve the iPhone 0 bytes available error and how to recover data from your iPhone with the best mobile data recovery software - MiniTool Mobile Recovery for iOS Free. 

iPhone Says 0 Bytes Available

iPhone is one of the most popular smartphones in the world. However, many iPhone fans have encountered the iPhone 0 bytes error when they take photos or install any new app on the device. Here, let’s see a true example:

When I go to my Camera Roll it says that I have 0 photos and it is really weird because when I go to Settings all the files appeared without a problem. And it says "I have 0 bytes available on my iPhone" which is confusing since I deleted almost all my data and I just have one app left. I have tried everything. I have restored all settings. I've seen/read every single tutorial. I just do not know what exactly to do and I don't want to restore my phone and lose all my videos and photos. I will be very happy to hear good news. I hope you can help me with this situation. It's really important for me to hear your opinion about this and how can I save my photos if nothing worked. THANK YOU SO MUCH. Greetings from Colombia.
