Why does my iPhone keeping saying I have low storage and 0 bytes?

I keep getting a notification on my iPhone 6 saying I have no storage so I click on the settings option it supplies. When I go onto that it said I have 0 bytes left.

I then thought I would delete a couple of bigger apps such as YouTube and a few more. My next step was to delete half of my photos so now I'm only left with 400. I deleted unnessesarry messages and mail I had. But after doing all of this it still says I have 0 BYTES LEFT!

I've only bought a couple of songs off of iTunes.

It's so frustrating because it keeps crashing my apps and causing them to not work properly. I'm having to constantly restart my phone and even after that sometimes it still don't work. When I'm texting someone the messages start scrabbling up and sometimes vanishing. WHAT SHOULD I DO?!

Typically it is because you ran out of iCloud storage, not phone storage. ICloud is a cloud based service that backs up your phone, after time it will hold so many backups that it can't house any more. I don't think that your phone is out of storage, it is most likely your iCloud. If this is the case you don't have many options. You can purchase a larger plan which is only around $12.

Do a hard reboot. To do this hold the power button down and the home button down at the same time until the white apple comes up. After this, check your numbers to see if they have changed. Works on mine.
