The real problem with Samsung is that they build their products with too much future proofing. Their products are designed so that they're still competive and useful for three to four years whereas the competition designs for obsolescence so you have to replace them every year and the OS upgrade purposely enforces this. Take for example the 2012 Note II from 2 years ago that has 2GB DRAM vs the iPhone that continues to be DRAM deficient in 2014 with 1GB even with known browser reload issues and premature background app closure causing data loss. Samsung's business approach is to build industry leading technology (AMOLED) and specs (DRAM) but rely on market growth versus Apple that builds relatively low end LCD and low DRAM to increase profit and rely on loyalty of smaller market share to drive annual upgrade sales. Now you have companies like Xiaomi, Opo/OnePlus, Huawei, etc. that matches Samsung's specs but not necessarily technology and are successful at grabbing market share in the middle ground between Samsung and Apple. One thing that sets Samsung apart though which will help their ability to weather the storm is that they're self sustaining having their own fab and manufacturing their own core components from SoC to display, flash memory, DRAM, baseband, camera sensor, etc. Qualcomm and Apple switching manufacturing of their SoC to Samsung from TSMC just shows how good their quality is.
