My device is stuck on the white restart screen, what do I do?

(I own an iPhone 7)

So around an hour ago I was on apple music playing a song and I went on snapchat and the app would crash and the music would stop playing whenever I tried to take a photo. I kept going back to apple music and trying to play music but all that would happen is an error message would pop up. I tried playing the music on youtube but the video would load and then just not play. After this I tried calling my dad but no sound came out of my phone and the speaker button kept going on and off even though I was not touching it. I finally just decided to plug in my iPhone and power it off. After a couple minutes I powered it on but then it got stuck on the white screen with the black apple logo. I connected it to my computer and have tried connecting it to iTunes with no luck, because iTunes needs me to put in the passcode on my iPhone. I have also tried many different ways of restarting, resetting it, and more. It has probably been more then an hour now and my iPhone is still stuck on the white screen. Any advice?

Apple store.

  • Will my jailbreak on one device transfer to another device via iTunes? So I bought an iPhone 5 today and I'm afraid to sync it to my Apple ID/ iTunes because my 8GB iPod is also synced to that iTunes account and its jailbroken. I don't want my jailbroken iPod to affect my iPhone 5. Will it affect it? I don't think it will but I just want to make sure before I sync it for the first time.

I got the screen replaced yesterday as it was badly smashed, and today when the phone went flat, it then went to the restart screen. The phone keeps blinking off and on every 30 seconds or so, but every time it's on, it's the white apple logo on a Blank black screen
