Troubleshooting Guide for iPhone 7

iPhone 7 Pro Manual User GuideiPhone 7 Manualtutorials Troubleshooting is a form of problem solving, often applied to repair failed products or processes. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms. Determining the most likely cause is a process of elimination eliminating potential causes of a problem. Finally, troubleshooting requires confirmation that the solution restores the product or process to its working state.

Troubleshooting Guide for iPhone 7

In general, troubleshooting is the identification of diagnosis of “trouble” in the management flow of a corporation or a system caused by a failure of some kind. The problem is initially described as symptoms of malfunction, and troubleshooting is the process of determining and remedying the causes of these symptoms.

A system can be described in terms of its expected, desired or intended behavior (usually, for artificial systems, its purpose). Events or inputs to the system are expected to generate specific results or outputs. (For example selecting the “print” option from various computer applications is intended to result in a hardcopy emerging from some specific device). Any unexpected or undesirable behavior is a symptom. Troubleshooting is the process of isolating the specific cause or causes of the symptom. Frequently the symptom is a failure of the product or process to produce any results. (Nothing was printed, for example). Corrective action can then be taken to prevent further failures of a similar kind.

The methods of forensic engineering are especially useful in tracing problems in products or processes, and a wide range of analytical techniques are available to determine the cause or causes of specific failures. Corrective action can then be taken to prevent further failure of a similar kind. Preventative action is possible using failure mode and effects (FMEA) and fault tree analysis (FTA) before full scale production, and these methods can also be used for failure analysis.

iPhone 7 Specs

Apple may potentially omit the 3.5mm headphone jack, a standard on every preceding iPhone, in favor of an all in one Lightning connector. This would accommodate a thinner chassis  perhaps shaving off as much as one millimeter. And there is fact to support this thesis: Philips showed off Lightning-only headphones earlier in 2015, though they apparently have yet to be released.

According to Barclays analysts, however, as reported by AppleInsider, the iPhone 7 will indeed omit a 3.5mm headphone jack. But, in its traditional place will be a second speaker, powered by an amp manufactured by Cirrus Logic. The analysts also countered recent rumors suggesting that the iPhone 7 would have dynamic noise cancellation, suggesting that it will use a digital codec instead.

iPhone 7 Multiple problems

iPhone 7 Un Official Guide PDFIsolating single component failures which cause reproducible symptoms is relatively straightforward.

However, many problems only occur as a result of multiple failures or errors. This is particularly true of fault tolerant systems, or those with built-in redundancy. Features which add redundancy, fault detection and failover to a system may also be subject to failure, and enough different component failures in any system will “take it down.”

Even in simple systems the troubleshooter must always consider the possibility that there is more than one fault. (Replacing each component, using serial substitution, and then swapping each new component back out for the old one when the symptom is found to persist, can fail to resolve such cases. More importantly the replacement of any component with a defective one can actually increase the number of problems rather than eliminating them).

Note that, while we talk about “replacing components” the resolution of many problems involves adjustments or tuning rather than “replacement.” For example, intermittent breaks in conductors or “dirty or loose contacts” might simply need to be cleaned and/or tightened. All discussion of “replacement” should be taken to mean “replacement or adjustment or other maintenance.”

As far as specification is concern, there is not much news about it however since very new iPhone (except S’s and C’s versions) are launched with latest iOS. So iPhone 7 will going to feature new OS i.e. iOS 10 which possibly be announced latest by September 2016.

If we talk about the screen size, the device is going to feature a little bigger screen than its predecessors i.e. iPhone 6 and 6 Plus which measure screen size of 4.7 and 5.5 respectively. Therefore the new iPhone will probably feature 5.8 screen size with OLED display. As far as camera is concern, iPhone 7 will sport improved 13 megapixel primary iSight camera with 8 megapixel secondary one.
