Iphone 11 slow response
I bought a new iphone 11 about a week ago.
Normally it works fine, but sometimes there is a serious delayed response which lasts about one or two minutes.
This never happened when I used my older iphone.
It seems like error happens when I lost my wifi signal but I'm not 100% sure. My cpu and storage usage are fine.
Any suggestion?
iPhone 11, iOS 13
