Apple and Samsung have a tricky relationship. At one end, the pair are competing for the top spot in the flagship smartphone market. At the other, Apple's got to rely on Samsung for components on the iPhone. The pair have been at odds for quite a while, with apple suing Samsung in 2011 for patent infringement. Now, with the iPhone 8, you can expect another major change in the smartphone industry. What is it? Take a look below to find out more.

Apple And Samsung To Mend Ties As Suit Settles In Supreme Court

For the iPhone 7, Samsung supplied only one component to Apple. Only the device's DRAM chips were manufactured by the Korean tech giant. The big loss for Samsung was the A10 Fusion. While the iPhone 6s and iPhone 6s Plus featured processors from both TSMC and Samsung, it was the former which won it out on the iPhone 7. Courtesy of InFO, which results in decreased contact area between the processor and the PCB, TSMC became the sole supplier of processors for Apple.

While trend will also continue in 2017, Samsung will supply Apple more than just DRAM chips next year. The iPhone 8 has been rumored with a lot of upgrades. One of these is the highly anticipated shift to OLED, as Apple finally chooses to abandon age old IPS LCD screens for the iPhone. The supplier for OLEDs will be Samsung, simply due to the fact that there's no other manufacturer out there that can fully supply Apple with the amount of screens that it needs.

In addition to OLED, Samsung will also supply NAND modules to Apple next year. While the company was able to pass up on Apple's orders for the iPhone 7, a new plant that the Korean company recently invested in will only reach full production capacity if it takes on Apple's orders. So the iPhone 8 will feature a lot of Samsung components, just like old times. To sum it up, NAND modules, DRAM chips and OLED screen will be supplied by Samsung for the device.

Of course, when we talk about screens, this relationship won't be permanent. Apple's primary manufacturing partner Foxconn acquired display maker Sharp last year. These efforts will go fully operational in 2018, so Apple will be back toward sourcing the iPhone's screens 'in-house'. Cupertino also intends to move toward Micro-LED screens in the future, so a lot of interesting upgrades are headed our way for the iPhone's display as well. Thoughts?
