Okay, so before we get started, I need to explain what I mean. Let me start off by saying that I have an iPhone 7 Plus and ever since iOS 10.2 was released, certain wallpapers actually make my iPhone drop frames when opening and closing SOME apps (Safari and Mail in 10.2.x and now even Messages in iOS 10.3). I think this bug ONLY affects the iPhone 7 PLUS models and not other iOS devices. So if you don't have an iPhone 7 Plus to test these with, then please do not contribute to the thread. I'm posting here today to offer up iPhone 7 Plus wallpapers that DO NOT make Mail, Safari and Messages stutter when opening and closing them. These wallpapers will help to make your iPhone 7 Plus smoother. If you're using a "good" wallpaper now, then you probably won't notice a difference, but if you're using a "bad" one, some of these could be really great for you. I'm not trying to start an argument and I already know some of you are going to be like "Dude, your iPhone is messed up, mine is perfect, there's no lag ever... yours is defective and you need to return it." my response to that is: This is my second iPhone 7 Plus and it does the same thing as my first. It only started with iOS 10.2. Yes I've restored. It only happens with most wallpapers, but others are perfectly fine. I know what I see with my eyes, so I know when I'm using a wallpaper that "works" and when I'm using one that doesn't work. These wallpapers could also help eliminate stuttering when opening folders as well. I think it has something to do with the iPhone 7 Plus resolution downsampling. Certain wallpapers might put too much strain on the downsampling process (or the blurring effect). The attached files are examples of wallpapers that make my iPhone stutter-free. If anyone has any they'd like to contribute, go ahead. I can test them for you.
