Failure Analysis: Samsung Galaxy Note 7 Introduction In August 2016, several Samsung's Galaxy Note 7 Smartphones were reported to explode. The manufacturer called upon its engineers to hurriedly diagnose the source of the problem. The initial report by the engineers pointed to existed of a fault in batteries procured from one of the suppliers. This led to a recall of Smartphones that had the batteries and continued shipping the new Samsung Galaxy Note 7 with batteries from a different supplier. However, the failure surfaced again with reports of the new replacements also exploding, prompting Samsung to halt the entire production of the Galaxy Note 7. The failure, subsequent recall, and the complete halt of the Galaxy Note 7 production have had social and legal ramifications. Background Smartphones have computing capabilities that are very advanced such as high definition cameras, media players, sensors, GPS navigation units, accelerometers, gyroscopes among other futures. For most Smartphones, an Android operating system is used. To operate efficiently, the features need to be supported by stable memory, batteries with the right power output, and an efficient power system, and a good shell. The risk of failure of Smartphones is mainly in the memory access violation and mobile phone hardware such as the batteries and the shell. Overall, studies on the failure of Smartphones have pointed to two major types of failures, i.e. accidental or malfunction of the software or Android. For this report, the focus is on hardware or software malfunction. Failure The explosion of the Samsung Galaxy Note 7 resulted in to recall of the phones. The specific phones that lwere overheating were taken for analysis to establish the causes of the explosion. The techniques emploved weny were overheating were taken for analysis to establish the causes of the explosion. The techniques employed for the analysis were Failure Mode and Effect Analysis (FMEA). This entails a critical analysis of the entire lifecycle of a product. It sanalyses the specifications of the design, operation, and maintenance by establishing the system functions, identification of the failure modes in the system, and functions which then leads to the determination of the effects and possible causes. The analysis covers both the software and hardware functionalities. The FMEA is used by engineers in the design stages of a product or posts analysis in the case of issues arising. The initial FMEA conducted after the failure was hardware FMEA. This is a straightforward analysis guided by the understanding that mechanical, electronic, and electrical failures happen due to some issues such as unanticipated stress, overload, and faulty wiring. The analysis of the engineers concluded that lithium-ion batteries from one of the suppliers had a fault. Part of the battery's inside coiled incorrectly, hence, caused stress to the battery. By performing critical risk analysis, the possible malfunction of software or hardware can be established before the product is launched into the market. The critical failure modes can be ascertained by calculation of the Risk Priority Numbers (RPN) through brainstorming. This helps to establish the potential areas of failure and the possible degree of damage. As a result, before the product is released, mitigation measures are taken to ensure that the risk is contained. It is thus paramount that Samsung should have carried out a thorough risk analysis for all the hardware and software from the suppliers before launching the product. Also, after the recall, the analysis was hurriedly carried out; hence, the conclusion that the failure was from a battery procured from a particular manufacturer was stheorised rather than being scientifically proven with quantifiable data.
