A new phone is being developed by Apple; the iPhone X Plus. The iPhone X Plus will have a 6.5 inch screen and will be about the size of the iPhone 8, but with more screen taking up the front. It is likely to cost even more than the iPhone X, but Apple is also working on a cheaper version of the phone. The cheaper version will probably have the same design, but less expensive features.
This relates to engineering because Apple needs to find out a way to increase the size of the phone while keeping all of the previous features and will also have to create a cheaper version and remove some of the expensive features in the phone. Here is a link to the article
