iPhone 7 Plus in bootloop and unresponsive after restore!

My phone is pretty much all around malfunctioning and I need help.

The first time problems arised was when I received a call and I could not hear anything and the microphone was not picking up my voice, so I tried resetting but that only caused my phone to enter a bootloop. I’ve dealt with this before so I tried entering DFU mode, letting the battery completely die, restart restart restart, but nothing. Wasn’t until I tried restoring where I realized something must be really wrong with the phone, tried restoring and it would just enter bootloop and never end. However sometimes the phone would actually start up if I updated the carrier settings before the restoring process finished. But even then the phone was acting super weird, the little pop ups asking you simple things like to cancel or allow location would cause the entire phone to become unresponsive, only way to get it back would be to press sleep button. After passing setup screen I started to check around the phone, both cameras did not work, speaker did not work, trying to toggle something in settings would freeze the phone , certain apps would not load up, App Store opened but never loaded anything. Safari did partially work but if I tried scrolling down on some pages it would just freeze again. I can send messages but that’s about it, WiFi and Bluetooth seem to be working as well. If the phone for whatever reason is turned off or has to restart then it will return into the bootloop unless I try to restore it to get it to work. There also haven’t been any screen replacements on the phone I am pretty sure, it just happened randomly about a week ago.

Does anyone have any advice on what might be the problem?
