Iphone 7 freezing and lagging almost unusable
I have had an iPhone 7 for a few months now and it has worked perfectly up until a few days ago. It started with the headphone/charger not playing music to the apple headphones. Instead, it plays it through the iPhone speakers. I thought that this might just be my headphones not working but I tried using my friends earpods and still the same result. Then I tried hard resets and every other form of reboot to try and fix the problem but I still can't use headphones. Then yesterday my phone started to lag. Noticeable when scrolling pages on the home screen or turning on and off. Now today I can't even use the phone. Every time I hit the on/off button or the home button nothing happens for over a minute. I can feel the haptics working in the home button so I know something is working. When the screen finally lights up the touch screen is non-responsive for another minute or so. Then whenever thing starts to work, it freezes again and is stuck. The on/off button does not work unless I hard reset and the home button has haptics but also does nothing. Same with volume buttons. I have no idea what is happening.
iPhone 7, iOS 10.2.1
