I need to erase the contents of my phone and restore to factory settings. Does anybody know how to save your texts so you don't lose them? Can I back those up to iCloud? My phone was very likely hacked (Apple's advice was to call the police!)

"I need to erase the contents of my phone and restore to factory settings. Does anybody know how to save your texts so you don't lose them?  Can I back those up to iCloud?  My phone was very likely hacked (Apple's advice was to call the police!)"
That was all I could put in the initial "box."  Then it brought me to this page with instructions on how to write a good sentence.
Proceeding ...
After going back and forth between Apple, AT&T and the police (all telling me to go to the other two) I took AT&Ts suggestion and got a new number. One tech warned against doing a backup, especially on my Mac, saying if my phone had been hacked then whatever bug was there would then invade my computer. But nobody knows how to determine if the phone has been hacked or a virus was planted there. Unfortunately I know who would have reason to do such a thing and all I can say is that he is at the top technologically and could easily do it. Almost impossible to prove, however.
So I need to preserve my text messages and my emails as well. I backed up my photos to that Microsoft product (One-Drive) and it froze (Surprise, Surprise) with four short videos to go, and no way of stopping that (when I tried it crashed repeatedly) so I'm in crisis mode here.

Betty I don't know if you fixed your hacking problem but I feel your pain. I've seen some strange things going on between my iMac and my iPhone and Apple has told me the same thing, call the police which I have done. The hackers have stole 500.00 out of my checking account have access to every internet account I use and no matter how often I change the password their right back on the account. I closed my FB account 3 times only to have someone reopen it. Right now I've got a link in my reading list (Safari) that if I click on it, it allows me to log onto my FB account anonymously.
I've seen a green folder come out of no where while I was trying to delete my passwords out of keychain when that green folder was put into the key chain I was immediately locked out. I than went into system preferences to try to make changes to my security settings, when I clicked on the icon it wouldn't open. I've seen log files of automator receiving commands and sending out my personal information thats on my computer.
I have a legitamate program called iExplorer that allows you to look at the contents of your iPhone back ups and saw a transaction someone made at the Apple store for some full length movies, some albums, ibooks and other apps but when I called the iTunes store and they said none of those items were showing up on my account. If their not on my account how can they be on my iPhone 6? One day someone was using my gmail account and unknowingly used google maps to search for an Italian restaurant, than a Mexican restaurant than a coffee shop and their search showed up on my iPhone but I didn't have my gmail account installed on my iPhone 6. Using my computer I logged onto my gmail account and looked at the maps history and sure enough there were the searches when I'd hover my curser over the link it gave me the longitude and latitude of the where the hacker was when he was using google maps. I know whoever reads this thinks Im crazy but I've documented everything and can prove the things that I have mentioned in this post actually happened.
One day I had my laptop (pc) and my iMac next to each other as I was using both. when I clicked on airport it showed that my laptop and my iMac had made a connection and were actually communicating with each other. I know I didn't do it I don't know how. The iMac was logged into my iCloud account while my laptop wasn't. I have formatted my iPhone at least a dozen times, Apple and an Apple retailer have formatted my hard drive not to mention the numerous times I have formatted it but the hackers keep getting on my devices. Im formatting my lap top at this very second because during the course of the night I left the ethernet cable plugged into it and they locked me out of my c: drive, and configured the system so I can't download any updates from Microsoft, overtime I type in www.microsoft.com it changes to ww38.microsoft.com which takes me to a blank page. I right clicked on the page I was redirected to and read the java script and couldn't believe that someone had actually configured Internet Explorer to redirect me to a blank page when I tried to go to Microsoft. Apples answer to all this is there was nothing wrong with my iPhone or my iMac and if I thought there was a problem to call the police which I have done.
Theres no doubt the hackers are reading this while I type it or will read it and I simply don't care anymore. I no longer email anyone, don't use my iCloud account and have taken precautions to protect my credit but if I ever find out who has invaded my privacy to this extreme the police are going to want to talk to me because Im going to hurt them like they've never been hurt before
