Qualcomm may still be the primary supplier of modems for the iPhone, but the second fiddle position is quite important and is in contention for 2019.

Apple is expected to split display production between Samsung and LG for one of this year's two OLED iPhone models.

The big reason for sticking with legacy display technology over new, exciting, colorful diodes? Pricing, pricing, pricing.

Component suppliers are speculating that Apple will finally ditch the Lightning connector on iPhones, iPads and iPods for a port now on MacBooks.

Samsung may want to follow Huawei's suit and beat Apple to the triple camera punch with a Galaxy S10 supporting "enhanced zoom features" and advanced AR applications.

They're still too expensive to source reliably and, with Apple's margin padding, would likely prove unappetizing for consumers to buy.

It's probably not happening this year, but in 2019, we could see Apple copy Huawei with at least one triple-camera iPhone variant supporting both 3x optical zoom and advanced AR experiences with 3D sensing functionality.

Last year's iPhone X was clearly only the beginning of Apple's transition to OLED display technology, with two 2018 upgrades likely to be followed by three 2019 iPhones snubbing the LCD tradition.

Triple-camera smartphones could soon become a thing, as the Huawei Mate 20 is expected to follow the P20 Pro's suit, with Apple likely to join the club in the fall of 2019 as well.

Taiwanese supply chain sources are calling for an affordable iPhone (at up to $800 starting price) lead the charts this year and a triple-camera iPhone next year.

A foldable iPhone that "could potentially double up as a tablet" is currently eyed for a 2020 launch, according to reputable Bank of America analysts.

While Apple is merely expected to refine and possibly shrink the notch later this year, 2019 iPhones could move away from the controversial design element entirely.

Apple might be more focused than ever on enhancing battery capacity for 2018, then 2019 iPhones in order to improve endurance and keep up with TrueDepth consumption.

To avoid future Face ID production woes, Apple has set aside no less than $390 million for a new Finisar VCSEL manufacturing plant in Sherman, Texas.

The front-facing TrueDepth cam on the iPhone X is responsible for Face ID and Animoji, but a 2019 rear-mounted 3D sensor could take AR to the next level.

Apple's first ever iPhone stylus could see daylight as early as 2019, according to The Investor's "industry sources", despite what Steve Jobs once said.
