Iphone 7 won't let me open apps, turn off the phone, or hard reset it?

I was on my phone looking at social media for a bit. Later, I unlocked my phone, tried to open messages and it wasn't working. I tried clicking all the other apps and none of them will open. I can't scroll through my apps. I CAN pull down the notification bar and the control center. I can turn on my flashlight but I can't open camera, alarm, or calculator. I can put the phone to sleep and wake it up, but I can't turn off the phone or hard reset it. I also can't get it to trust my computer when I plug it into it. Can anyone help? (I have iOS 11)

Iphone 6s not turning on?

I recently lost my iphone 6s and got a replacement. It is about a week old and today it stopped charging. I tried different outlets, usb ports, and chargers. I cleaned the charger and port. I turned it on and off again and did a soft reset before it died. I attempted a soft reset again when it went into recovery mode on its own. I then updated Itunes on my pc, but it will not connect to my phone. My phone then told me it was charging but never turned back on. I can't put it back in recovery mode and it will not even display the charging screen.

My iPhone 7 won't turn back on?

So lately my phone has been really slow and keeps saying I have no storage. But I have plenty of storage so then I decided to restart phone (button on side) to see if it will work better and run apps faster but it didn't work. My iPhone keeps showing that it's turning back on with the white Apple screen but then keeps shutting off no matter what I do. What do you think happened to it? I really don't want to pay for a new phone when i don't know what happened

Why is my USB Port in my Pontiac G6 not playing music anymore?

I bought a used Pontiac G6 a few months ago. It's a 2010. It has a USB port on the radio that charges your device while playing music on it. The port will charge my phone and say "usb device connecting" but then after 5 min of waiting with that phrase on the radio screen, it goes away and continues playing the radio and charging my phone. Basically, it won't connect to my phones music. It was working perfectly fine up until two days ago. Already tried using different chords. No luck. If someone could help me that would be magnificent! I have an aux but I have an iPhone 7 and ordered the aux adapter online for it and it has yet to come in so I'm stuck with no music and it sucks.
