Backed up my phone through my mac and now everything from the past year is deleted! My phone is how it was last summer: photos, wallpaper?

I plugged my iphone into my laptop (mac), it asked if I wanted to back up my phone so I did, now my phone is exactly how it was a year ago. It's my old wallpaper, my old apps, and when I go into photos the most recent photo is from 2018. Everything from the past year is gone.

Added (1). Is there any way to reverse what I've just done? This is absolutely horrible, all my pictures from the past year have disappeared, all my notes with important passwords, everything.

How do I get my music back?

I have songs that purchased on my iPod in the iTunes Store and digitally downloaded onto my iPod like… YEARS ago but still using the same account. But at some point I deleted them from my library and whatnot and considering I paid money for them I expected to be able to download later on but now they are nowhere to be found in my purchase history and when I look them up on iTunes Store it shows the 1.29 cents icon as if I never bought it. I'm using an iPod touch 6th gen with the latest iOS if anyone knows how to get my music back that'd be great nothing I find online is helping.

Why does my iPhone say insufficient remaining credit?

I was playing the game of life on my iPhone 7 and I have $21.13 in credit. I was going to buy the season pass for $19.99 so I have more than what I need. But I tried redeeming and it said I had insufficient remaining credit. I tried to restart the phone, log in and out of iTunes, and delete and redownload the game of life. But it still didn't work. And I can't contact hasbro about this. There's no Q&A. Do any of you know how to fix this?

Phone overheating issues?

I have an iPhone 7 Plus and for the most part the temperature is fine.
I sometimes live stream on an app called MeetMe however and my phone just doesn't seem to get along with it well at all, it's not just me either I've heard many other people saying that this one app causes there phone to overheat so much that it'll turn off to cool down.
At the same time I've also heard from many others that they have no issues at all.
I first thought the problems were purely a result of my phone being over a year old now but my best friend has a brand new iPhone and she has the same issues.

I was just wondering if there's anything I can potentially do to limit this because I personally love live streaming and this is one of the best apps for doing so.

IPhone 5S not updating?

My phone does not turn on or charging. I comes up with the iTunes symbol on a black screen. I tried updating it and it comes up with errors 14 and 9006. I tried changing the USB cables, the USB port, restarted the computer and iTunes and turned off the firewall in an attempt to revive my phone but nothing.

I have a lot of important data on my phone, especially my text messages, contacts and recent photos that I can't afford to lose. I have looked in icloud.com and it appears that my text messages, recent photographs have not been backed up. I'm stressing out now because my phone is not turning on and I can't backup the recent data I have.

Can someone help me or advise me what I can do as I do not want to restore my phone because I know once I restore my phone, it will wipe everything - from my text messages to the smallest contents.

Please advise if there's a software that I can download to backup my phone or is there something else I can try before restoring my phone.

Why does my phone turn on when I pick it up?

I got an iphone 7 about 2 weeks ago, and every time I pick it up it turns on. In fact, almost every movement that I make with it it turns on. I've tried looking for an option in settings to make it stop doing that but can't seem to find it. (Or at least I don't know what it's called) Does anyone know how to make it stop doing this?

What does this mean on an iPhone?

The other day my husband was showing me a YouTube video on his phone, when he swiped up to brighten the screen I saw a little circular icon/photo 1 of his best friend and another of a girl he used to date, I've never had this on my phone so I'm not sure what it means, does that mean those same people liked that video or does that mean he has an open text or chat with those people? I'm just a little confused.
