Qualcomm previously teased the Snapdragon 820 back at Mobile World Congress 2015. The manufacturer switch to Samsung was revealed by personnel familiar with Qualcomm company plans. As reported by Re/code:
The company has relied on Taiwan-based TSMC to produce the majority of Qualcomm chips, but it's believed TSMC will be used as a backup to handle extra capacity required to meet demand. Qualcomm isn't the only major partner for Samsung looking to utilize its advanced chip-making facilities. Apple is also reported to be using Samsung's assets to produce the A9 chip for the next wave of hardware.
