IPhone still says i have 20GB of photos when i deleted everything?

And before you ask, yes i deleted everything from my recently deleted folder and yes i tried the date & time trick, nothing worked. Its frustrating because thats 20GB i could be using for something else. I backed up all my photos and everything is deleted and gone but it still says something is occupying 20 gigs on my phone. Is there a fix for this? Or will i have to call apple or actually go into the store

Recover iPhone photos when all has failed?

My iPhone 8 Plus was water damaged while on vacation and the right side of the screen does not detect any inputs. One digit of my passcode is a 3 and I can't press it to access the phone. When I plug in the iPhone via usb cable it says "unlock iPhone to use accessories" and of course I can't do that due to my inability to press the "3" key on the passcode screen. I've looked for ways to bypass the "unlock iPhone to use accessories" and all the methods involve going into settings, which of course I can't do

Why is the call restricted?

I have been trying to call my friend since last night and whenever I call it says "The service you are attempting to use has been restricted or unavailable…" I have Metro PCS but I'm not sure what service he has. Text messages aren't going through either, and we both have iPhones but it doesn't say "delivered" when I text him. Could his phone possibly be off or am I blocked for whatever reason? It's only happening when I call or text him, everyone else is working fine. What is going on?

IPhone 6s microphone issues?

Having issues with my iPhone 6s microphone. Hey Siri doesn't work, nor does talk to text/dictation. When I try to FaceTime someone they can't hear me BUT when I use Facebook messenger video chat they can hear me. Same with general calls on speaker phone, no issues. If I plug my headphones in I can talk to text and the phone picks up what I say. I've tried about everything I can find online to try and fix it but I can't find any scenario similar to mine. Thought?
