I've been experiencing a problem with my iPhone storage related to my photos app. How can I fix this?

It's been this way for a while. I only have 29 photos, none of them are high quality, but no matter what I do, my photos app says that the documents & data take up 308.1 MB. Since it says that, I can't fit much on my phone. I'm very low on storage and I'm desperate to fix this problem. I've tried everything you can find with a simple google search and a bit more looking. I downloaded iExplorer, that didn't work. Nothing is working. I don't get why these issues are still a thing, not only that but when I hook my phone up to my PC, iTunes says I have 4 GB free, except I don't, and when I try to sync more to my phone it says I can't fit anything. 4 GB basically means 0 GB, but that's not the problem I'm focusing on at the moment, I just want more storage. Please somebody help, this is really inconvenient and it stresses me out.

Why can't my boyfriend get any of my text messages?

This happens occasionally. Sometimes he gets them but sometimes he doesn't. He has an Samsung android or whatever and I have an iPhone. It's really annoying. He needs a new phone anyways because the battery goes super fast even if he isn't using it. His phone also has been recently just turning off by itself but he thinks it's just because it runs out of battery. He has gotten a new battery several times but it doesn't do anything.

Would you have given him the pretzel?

Walking into the mall i saw a guy panhandling outside so i decide to get the guy a pretzel from this place because it has a lot of carbs which would be good for him. Walking out i saw him looking at something which i thought was a dog but turned out to be a iphone he was hiding behind the sign so i decided not to give him the pretzel cause hes a faker
