A few weeks ago I received an email from a hacker?

He stated that a couple months earlier i was on an insecure Wi-Fi network and he hacked into my firmware system to my iphone 8plus. He then told me that if i didn't send him 900 he would lock my device on me.

Well today, i believe that happened. One second I was able to put my password in. The next i couldn t get in with my thumb print nor my password. I tried to hard reset the phone with the up down volume buttons and side, it looks like it is going to reboot, then turns back on and disables me from the phone for another hour. I tried to connect the phone to my computer to factory reset it but, when I plug it in a message pops up saying "unlock to use usb device"

is this even possible for someone to hack my firmware and change the password on my phone.

My mom is dangerously secretive?

My mom has always been a secretive person for as long as I've known her. My siblings have never asked but she's never told us anything about our father. She gets out of work but doesn't come home until 1 or later in the morning and sometimes doesn't come home at all. She tells us absolutely nothing about her life. If we're ask her where she's going she won't tell us and we know there's no point in asking. We also all have a gps locator on our iphones but she turns hers off after she leaves work. I understand that because all my siblings are older (the youngest is 17), she may feel like she's free to do what she wants pero, we worry for her and what couldve happened to her when she doesn't come home. We don't have to know everything pero, a simple name of who she's going out with would be nice. If we were to lose her, i'm sure we'd have almost nothing to give the police except physical traits.

IPhone is at 85 percent battery health?

So I have had an iPhone 7 for close to 19 months now. It has just recently gone down to 85 percent battery health. Is that about normal for an iPhone's battery health? I know that the critical battery health percentage is 80 percent.

How do I ask for my iPhone back?

My mom had recently took my iPhone only because she wanted it. In return I got a android that i do not like. I got that iPhone for my birthday present and I really do want it back.
