iPhone 7 Plus 256gb and I was just normally doing tasks by clicking on the calendar event on the widget page. It brought me to the calendar and then everything stopped functioning. Touch screen unresponsive, I can't force restart, home button unresponsive and it just stuck there for 2-3 minutes. Then screen started spazzing and then just froze again. I then pressed the lock buttton and everything back to normal. But seriously ? What's with the lagging and freezing? Even with all the technology in here??
