Apple will be releasing not one, not two, but three new iPhones in 2017. If rumors prove true, Apple will add the iPhone 7s, iPhone 8, and another smartphone to its stable.

The rumor started with KGI Securities analyst Ming-Chi Kuo who believes Apple is planning on releasing three new smartphones with different displays.

"We look for new 2017F iPhones to come in three models: one OLED model, and two TFT-LCD models with 4.7-inch and 5.5-inch display. We believe the OLED and 5.5-inch TFT-LCD iPhones will feature dual-camera. Based on this prediction, our forecast of dual camera adoption rate in new 2017F iPhone models is revised up from 30-40% to 65-75%. We view this increase as favoring Largan's sales and profit momentum as it is the exclusive supplier of wide-angle and telephoto lens. It also bodes well for Apple's dual camera software ecosystem."

It is not clear which is which but another rumor indicates that the iPhone 8 will be a high-end phone that with an OLED display. There are a number of versions of this rumor and most concerns the actual size of the display.

Kuo discussed these rumors saying, "In terms of the display size of the OLED iPhone, current information from the upstream points to 5.8", while that from the downstream points to 5", which does not conflict, in our view."

The iPhone 8 will obviously be Apple's next flagship smartphone and it is safe to consider that it will be the high-end OLED phone that is being talked about in rumors.

Kuo described the OLED phone as having "significant changes in form factor". It will possibly have a dual-camera system including a FaceTime camera, an embedded earpiece, and the Touch ID fingerprint sensor. Other rumors say that the iPhone 8 will be the biggest smartphone yet.

The other two iPhones will have traditional LCD displays and will differ mostly in their sizes, as mentioned earlier. Kuo indicated that the two other iPhone may possibly use glass casings in lieu of metal.

The iPhone 7s will also not have a second camera according to rumors.
