I need to detect the devices for IOS devices by JS, for iphone-6 I check it by the ratio and devicePixelRatio, I didn't find any information to check if the device is iPhone 7 plus.
I found information for the older devices,
What are the device-width css viewport sizes of the iPhone6 and iPhone 6 Plus
or this
iPhone 7 has same device width/height as the iPhone 6: 375x667 iPhone 7 plus according the same: 414x736
