Try restarting the phone: Restart your iPhone, iPad, or iPod touch - Apple Support
Mister Finch, thank you for your response, but if you would read it carefully, you would it saw that I had this future like everyone else for some months now, and obviously I've try restarting it, even put in in dfu mode and give it a restore, and nothing..
I have read your post very carefully again, and I did did not see that you said you tried restarting it. As my mind-reading skills aren't working today, there are probably other things about your situation that I would know if they were (that you haven't said), so I'm throwing in the towel.
BTW, "everyone else" is patently false, as I do not have the problem. And iOS 11.3 has only been out for a few weeks, so it is impossible that everyone else (or anyone else) has been reporting it for some months now.
I don't volunteer here to be abused. Goodbye.
