S60 user interface

S60 (formerly known as Series 60) is one of the major smartphone user interfaces. It is developed mainly by Nokia and uses the Symbian OS as its base. Besides using it in all of its own smartphones, Nokia also licenses S60 to other manufacturers such as Samsung and LG. S60 is capable of running native third-party S60 applications as well as regular Java applications.
There are several releases of the S60 UI and chronologically they include Series 60 (2001), Series 60 Second Edition (2004), Series 60 3rd Edition (2005) and S60 5th edition (2008).
Thrid-party software written for S60 1st Edition (S60v1) or 2nd Edition (S60v2) is not compatible with S60 3rd Edition (S60v3) and later because it uses a new version of the Symbian OS (v9.1).
The latest S60 5th edition was announced in October 2008. Nokia decided to move directly from the 3rd Edition to the 5th Edition "as a polite gesture to Asian customers" since the number four is considered bad luck in some Asian cultures.
The major feature of S60 5th Edition is support for high-resolution 640x360 touchscreens. Before the 5th Edition, all S60 devices had a button-based user interface.
S60 5th edition has some support for third-party software developed for S60 3rd edition but, it's currently limited and somewhat hit-and-miss.


SAP (SIM Access Profile)

SIM Access Profile is a Bluetooth profile allowing a GSM phone to share its SIM card with another device of the same type.


SAR (Specific absorption rate)

Each GSM handset has a radio transmitter and receiver in order to operate in the wireless GSM network. That transceiver is manufactured so that when used next to the ear and when worn on the belt, it won't exceed the limits for exposure to radio frequency energy set by the authorities.
The authorities in question here are the Federal Communications Commission (FCC) of the U.S. Government, Industry Canada of the Canadian Government (IC), and the Council of the European Union. These limits are part of comprehensive guidelines that establish permitted levels of RF energy for the general population. The guidelines are based on standards that have been developed by independent scientific organizations through periodic and thorough evaluation of scientific studies.
The exposure standard for wireless devices employs a unit of measurement known as the Specific Absorption Rate, or SAR. Unfortunately the limits set by the FCC/IC and the Concil of the European Union are measured over different amount of tissue so they are not directly comparable.
• The SAR limit set by the FCC/IC is 1.6W/kg averaged over 1 gram of actual tissue.
• The SAR limit recommended by the Council of the European Union is 2.0W/kg averaged over 10 g of
actual tissue.
Although the SAR is determined at the highest certified power level, the actual SAR level of the device while operating can be well below the maximum value. This is because GSM phones are designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output of the device and vice versa.
As of 2010, we at GSMArena.com have added the officially set SAR values for most models in our database. You will find we list several SAR values. The reason for that is the FCC/IC have stipulated that SAR
should be measured at both hip level (making calls while carrying the phone at the waist) and at head level (making calls with the phone put next to ear). So you are almost certain to see two SAR values for the FCC/IC standard.
The Council of the European Union only requires the measurements at ear level so most manufacturers don't measure SAR at hip level for European models. So in this case you are almost certain to see a
single SAR value only for the EU standard.


Screen protection

As touchscreen displays are growing larger in recent years, the need for enhanced scratch resistance and protection of the screens created the demand for usage of screen covers of increased resistance including chemically hardened glass.
Corning's Gorilla Glass is a popular brand of hardened glass used for high-end handset in the mobile industry.
Additionally, manufacturers has started applying oleophobic coating on top of its screens to make finger smudges less of an issue.


SD (Secure Digital)

Secure Digital or SD is a popular type of memory card. Memory cards are based on Flash memory and are used as solid state storage, their main purpose being an inexpensive way to store or transfer data between computers and other digital products.
The dimensions of an SD card are 24 x 32 x 2.1 mm, which makes it smaller than CompactFlash but larger than miniSD, microSD (TransFlash) and RS-MMC.
SD cards are about the same size as MMC but a bit thicker. They provide a bit more speed than MMC at the expense of higher power consumtion. SD cards also provide a hardware lock that can protect the stored data from being erased.


Secondary camera

This refers to a second, usually lower-resolution camera, typically positioned on a device so as to face the user in applications such as video conferencing.


Sensors

Modern mobile phones come with a variety of sensors that automate or easy many of our daily tasks. This field takes into account the presence of an accelerometer, a gyroscope, a compass, and a barometer.
Accelerometer and gyroscope
Accelerometers in mobile phones are used to detect the orientation of the phone. The gyroscope, or gyro for short, adds an additional dimension to the information supplied by the accelerometer by tracking rotation or twist.
An accelerometer measures linear acceleration of movement, while a gyro on the other hand measures the angular rotational velocity. Both sensors measure rate of change; they just measure the rate of change for different things.
In practice, that means that an accelerometer will measure the directional movement of a device but will not be able to resolve its lateral orientation or tilt during that movement accurately unless a gyro is there to fill in that info.
With an accelerometer you can either get a really "noisy" info output that is responsive, or you can get a "clean" output that's sluggish. But when you combine the 3-axis accelerometer with a 3-axis gyro, you get an output that is both clean and responsive in the same time."
Digital compass
The digital compass that's usually based on a sensor called magnetometer provides mobile phones with a simple orientation in relation to the Earth's magnetic field. As a result, your phone always knows which way is North so it can auto rotate your digital maps depending on your physical orientation.
Barometer
And finally, you may see a device sporting a barometer in its specs sheet. Contrary to what you may suggest, it has nothing to do with weather. Instead, the barometer is there to help the GPS chip inside the device get a faster lock by instantly delivering altitude data.


Side Keys

The side keys are the buttons situated on the sides of the phone that you can use while holding the phone in one hand.


SIM

A subscriber identity module is a removable smart card for mobile phones. SIM cards store the required information to identify the mobile device. It also contains data required for voice encryption to make listening in on calls almost impossible (except when the wireless carrier itself is doing the eavesdropping). In this way the customer ID (and personal number) is tied to the SIM card and not to a certain mobile phone. This allows for a seamless interchange of the same SIM card between different GSM mobile phones.
SIM cards also serve as storage for SMS messages and the user's contacts. Current SIM cards can store up to 250 name/number pairs and up to 50 SMS text messages. The SIM card cannot store multiple numbers per contact or other more complex information. This means that if you copy your contacts info from the phone memory to the SIM memory, contacts get broken up into as many entries as there are numbers for each individual contact and discards the other information.
All GSM phones and most iDEN phones require a SIM card to operate. There are certain types of phones (CDMA, TDMA, AMPS) that do not use a SIM. Instead, the required data is programmed directly into the phone.
The SIM cards come in two standard sizes: the first one 85.60 x 53.98 x 0.76 mm and the newer and far more popular version 25 x 15 x 0.76 mm.
There are two numeric passwords associated with a SIM card. One is the Personal Identification Number (PIN) that the user must input each time they start the device (this can be turned off via the phone settings). When entering the PIN number the user has only three input attempts. If all three are incorrect, the card gets locked and a PUK (Personal Unblocking Key) must be entered in order for the card to work again. Only ten attempts to enter the PUK are permitted before the card is permanently locked and made unusable.


SIM lock

GSM phones can be "locked", that is made to accept only SIM cards belonging to a specific network. Typically, this is done so that phones will work only on the network of the carrier.
SIM-locked phones are usually locked to a carrier when the carrier sells the device at a subsidized price in order to attract new subscribers to its services.
Some carriers offer a SIM unlock option to their subscribers after a certain amount of time has passed. Unlocking the phone can be done by entering a special code which is generated based on the phone's unique IMEI number.
Some third-party shops offer unauthorized unlocking of SIM-locked phones, but using their services usually voids the official warranty of the phone.


Single-Band

A single-band phone is one that operates on one frequency only. This makes the phone unable to operate in areas where the service providers do not support its frequency.

Smartphone

A smartphone is a term used to describe a category of mobile devices with computer-like functionality. These
devices sport complete operating system and have a platform for application developers.
Currently, the two major smartphone platforms in use are Android (by Google) and iOS (by Apple). An application written for a specific platform can usually work on any smartphone using the same platform.
Applications for smartphones are also faster and better integrated with the phone's UI than Java applications. Smartphones have larger displays and faster processors than so-called feature phones or dumb phones .


SMIL

Synchronized Multimedia Integration Language is a standard for interactive audiovisual presentations and is commonly used in mobile phones' MMS messaging. These messages integrate text with images and audio/video streaming. The abbreviation SMIL is read as "smile". A typical SMIL presentation consists of multiple "slides" playing in sequence.


SMS (Short Messaging Service)

SMS or the Short Messaging Service allows users to send and receive personal text messages directly between mobile phones or sometimes to email adresses. Each message can be up to 160 characters long (when using the default character set) and can be sent to and from users of different operator networks. All mobile phones support SMS. Recently mobile manufacturers have started offering special reading layouts for SMS inspired by Instant
Messengers such as ICQ, Skype, and MSN. The so-called threaded message layout or conversation-style layout displays the incoming and outgoing messages between two participants in a single pane ordered chronologically.
This enhancement reflects the recently prevalent use of SMS as a type of instant messaging much like you would chat on a computer. When possible we try to explicitly state that a mobile phone supports this enhanced messaging view.


SNS (Social network service)

A social network service or social networking service, most often called SNS, is a medium for establishing social networks of people who share interests and/or activities. Social networking sites allow users to share ideas, activities, events, and interests within their individual networks. Most social network services are web based and provide means for users to interact in various ways, such as e-mail and instant messaging.
Modern internet-connected always-online phones stake a lot on SNS connectivity and integration with the various services getting more popular than ever.


Soft keys

Soft keys (a.k.a context keys) are keys with varying functionality depending on the context they are used in. These are usually situated right under the display and their current function is shown above it.


Soft Reset

A Soft Reset is the act of rebooting or restarting your device in order to clear its internal (non-storage) memory of running programs. This is a way to start afresh if an application is causing problems and is normally only used on smartphones.
Windows Mobile smartphones usually have a dedicated soft reset pinhole that can only be pressed with a sharp, pointed object such as a stylus. It's designed to perform a soft reset when the device becomes unresponsive.


Speed Dial

A feature present on all mobile phones that allows the user to program a button from the alphanumeric keypad to automatically dial a custom phone number upon a longer press.


Stand-by time (battery life)

Stand-by time is the officially quoted longest time that a single battery charge will last when the phone is
constantly connected to the GSM network but is not in active use.
The stand-by time is highly dependent on the cellular network environment, such as the distance to the closest GSM cell tower (base station). Moving the phone (as in a vehicle) also negatively affects battery life. Manufacturers measure talk time in controlled conditions and the quoted numbers are rarely reached in real-life scenarios. These numbers are best used as reference when comparing phones from the same manufacturer because battery life measurement methodology will probably vary from manufacturer to manufacturer. Quite often you will find the Stand-by time field in the specification pages of new phones empty as the manufacturers sometimes fail to disclose the info at the official announcement. Later on when the handset hits the market, the figures are usually revealed and accordingly, we take the care to add them to the database.


Stereo Speakers

Stereo speakers are two speakers built into a single device. They are usually positioned on the left and right side of the device and each speaker uses the respective channel of stereo sound, thus producing a stereo effect.


Streaming Video

Streaming video is a feature that allows real-time viewing of web video on a mobile device. This allows users to enjoy a video without downloading it prior to watching.


Stylus

A small mechanical tool used to work with touch-screen devices. It is usually a simple stick of plastic or metal in the shape of a thin pen which has a softened tip so that it does not damage the screen.
Because of its familiar shape, handwriting and drawing on the touch-screen is much easier for the user, and it
achieves far greater accuracy than a fingertip.


Sub-QCIF

Sub-quarter common intermediate format is the smallest standard image size. With its resolution of 128 x 96 pixels, it provides low-resolution video clips and streaming video on mobile phones.


SVGA

Super video graphics array is a standard size for images and displays. SVGA indicates a resolution of 800 x 600 pixels.


Symbian

Symbian OS is an operating system designed for mobile devices. The Symbian OS is used as the underlying base for two major smartphone platforms: S60 and UIQ. Generally, applications written for one of these platforms are not compatible with the other but as they use the same underlying OS it is easier for developers to convert applications from one of them to the other. The Symbian OS introduced major changes to version 9 that made all previous software incompatible without updating. The platforms based on Symbian subsequent to version 9 are the UIQ 3.0 and later, as well as S60 3rd edition.


SyncML

SyncML is a standard for personal organizer data synchronization between different devices. This can cover any type of personal organizer data, such as contacts, to-do lists, notes etc.
The devices synchronized can be mobile devices (phones, PDAs) as well as stationary ones (PCs).SyncML even enables synchronization with web sites as it features an XML-based standard that all SyncML-compatible devices can recognize.
