What happened to my iPhone?

My phone (iPhone 5c) randomly crashed last night, it went black and had a loading symbol like it does when it dies. It came back on a little bit later and half of my photos were completely gone. It happened again about 20 minutes later and this time i had 0 photos and soon I was unable to open the photos app. I took a screenshot of it and it disappeared later on, same thing happened with a photo i took of my bedroom window. This morning I deleted a few apps on my phone thinking maybe i had run out of storage and it was hiding my photos from me. I opened my camera app a few minutes later and all of my photos came back for a few minutes and disappeared again. I saw that i was signed out of my icloud account and my twitter account for some reason as well, I tried to sign back in for nearly two hours (I was in the car this time and had bad service) but i finally got signed back in (icloud made me add my phone number to my account and now i need a pin to sign into my account) and my photos are still gone and i can't open my photos app. I didn't have icloud backup on so i won't get my photos back but as of now my phone has crashed like it did last night a total of three times. Has this happened to anyone else? What should I do? (I tried to upload this to discussions.apple.com but i was not allowed.)

What should I go for iPhone X or 8+?

I'm planning on paying my own phone bill soon. I have a friend told me that iPhone 10 is already out. When I went to the phone store I assume iPhone SE was the 10 bc my friend told me that it a promotions.

I hit up my friend. He told me that the X is the 10. I shouldn't get the x cuz Apple comp. Rush the phone. If I get the X I will have a lot of manfunction errors with the phone. Wait for the 10S or 10+ to be on the safe side.

I can be wrong but I remember seeing X and 8 came out the same date. Like how 5s and 5c are out the same date. I think it the special edition version of the iPhone.

It is better to buy a new phone or repair my phone (Apple 6s)?

So my iPhone s battery just stopped working as well as it was last week. This was suddenly, then my phone fell in the toilet yesterday and now the LED doesn't work. To add to that, the screen edge is broken. (also the phone got slower but probably a reset would solve that) Should i repair my phone or get an iPhone 8? I'm trying to get the best out of my money. (yes i have considered getting an android but once you go black you never go back.

Added (1). I forgot to mention that I have had this phone for 2 years!

How much will I get charged if I over-use data on Wi-Fi instead of mobile?

So, I love to watch youtube on my phone or netflix at night to keep me occupied until I get a little sleepy. Since I know full well that using youtube or netflix on mobile will increase data usage by a large amount especially on cellular/mobile data. But what about on Wi-Fi data? Will my verizon bill still skyrocket from Wi-Fi data usage or is it connected to my internet bill for my home. A little confused on how exactly Wi-Fi usage gets billed on phones like android or Iphone.

Someone stole my phone. What should I do?

I was selling my iphone 8 plus for $800 on the app called Offer Up. When I met the guy who wanted to buy it he just snatched the phone and threw counterfeit money at me. I filed a police report and the officer pretty much told me he couldn t do anything. I found the guys Facebook who stole my phone. What can I do? Can I sue him? I tried reporting it to the detective but they re not doing anything.
