KGI Securities analyst Ming-Chi Kuo currently has a good track record when it comes to speculating what comes next for Apple. Back in late 2015, Kuo predicted that the California-based company will reportedly bring a 4-inch iPhone to the market, and Apple did so with the iPhone SE that it officially announced during its March 21 event. Now, Kuo is at it again, noting that Apple will be revamping its iPhone series in 2017 with an AMOLED display.

9to5Mac reports that, according to Kuo, Apple will be going with glass, plastic, or ceramic for the casing of the iPhone that will come out in 2017. However, it looks like the company could settle on a glass casing, similar to what the iPhone 4 featured back when it was released. Apparently, plastic isn’t capable of offering form factor designs that are thin and light enough. On the other hand, it’s also difficult to control the tolerance of ceramic.

What’s more, it could even sport a curved display along with a glass body. It’s also reported to feature glass panels on the back, and metallic sides similar to the iPhone 4. Moreover, Kuo notes that the upcoming iPhone will have a completely new form factor that comes with narrow bezels as well as a more comfortable grip.

According to Macrumors, Kuo says that there are two possible scenarios that will come out for Apple’s lineup in 2017. Should supplies be enough, the company could release a 4.7-inch LCD based iPhone, with the AMOLED variant reserved for the bigger variant. However, if it turns out that the production for AMOLED displays are not enough to meet the demands for larger screens, the company will still retain LCDs on iPhone with 4.7-inch and 5.5-inch displays. However, the AMOLED variant will be for the 5.8-inch model that will seem to be more expensive than the rest.
