iPhone 6 Plus screen locks up
I bought a iPhone 6 Plus from Walmart it is a refurbished I also bought a warranty with it, which I’m not sure how that works but my problem is my phone will lock up sometimes when I open it or get a all that I can’t answer , then sometimes it gets really crazy it will start failing crazy numbers and it will jump to web and go back to railing and opening apps wild to watch/ I’ve only had phone 2 months I have done a restore on computer I’ve done a dfu restore I’ve also did a cloud restore my he also done it as new phone. It is a 64 gig I’ve tried taking apps out one at a time but it just goes crazy sometimes but the problem I will face soon is I’m having bypass heart surgery need to see if I can fix this myself I’m sure it will take longer than two weeks to fix I’d like to have it with me so I can contact people so they don’t worry . I probably should call apple store see if there open but with this virus thing I might be out of luck for a while. If any one has had issues like this and got it working again I’d like to hear , I don’t know what the phone had done before I got it but it looks brand new no scratches it’s in good shape . Thank you for looking
