i phone

iPhone (/ˈaɪfoʊn/ EYE-fohn) is a line of smartphones designed and marketed by Apple Inc. They run Apple's iOS mobile operating system.^[14] The first generation iPhone was released on June 29, 2007; the most recent iPhone model is the iPhone SE, which was unveiled at a special event on March 21, 2016.^[15][16]
The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPhone has Wi-Fi and can connect to cellular networks. An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send and receive text messages, follow GPS navigation, record notes, perform mathematical calculations, and receive visual voicemail.^[17] Other functions—video games, reference works, social networking, etc.—can be enabled by downloading application programs (‘apps’); as of October 2013, the App Store offered more than one million apps by Apple and third parties^[18] and is ranked as the world's largest mobile software distribution network of its kind (by number of currently available applications).^{[citation needed]}
There are nine generations of iPhone models, each accompanied by one of the nine major releases of iOS. The original 1st-generation iPhone was a GSM phone and established design precedents, such as a button placement that has persisted throughout all releases and a screen size maintained for the next four iterations. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a faster processor and a higher-resolution camera that could record video at 480p. The iPhone 4 featured a higher-resolution 960×640 "Retina Display", a VGA front-facing camera for video calling and other apps, and a 5-megapixel rear-facing camera with 720p video capture.^[19] The iPhone 4S upgrades to an 8-megapixel camera with 1080p video recording, a dual-core A5 processor, and a natural language voice control system called Siri.^[20] iPhone 5 features the dual-core A6 processor, increases the size of the Retina display to 4 inches, introduces LTE support and replaces the 30-pin dock connector with an all-digital Lightning connector. The iPhone 5C features the same A6 chip as the iPhone 5, along with a new backside-illuminated FaceTime camera and a new casing made of polycarbonate. The iPhone 5S features the dual-core 64-bit A7 processor, an updated camera with a larger aperture and dual-LED flash, and the Touch ID fingerprint scanner, integrated into the home button, and fitness tracking facilities. The iPhone 6 and iPhone 6 Plus further increased screen size, measuring at 4.7 inches and 5.5 inches, respectively. In addition, they also feature an A8 chip and M8 motion coprocessor. The iPhone 6S, iPhone 6S Plus, and iPhone SE all feature Apple's new dual-core 64-bit A9 chip, 2GB of RAM, a GT7600 (6-core) GPU, and the 3D Touch feature, which was introduced in the trackpads of the MacBook lineup as Force Touch. As of 2013, the iPhone 3GS had the longest production run, 1,181 days; followed by the iPhone 4, produced for 1,174 days.^[21]
The resounding sales of the iPhone, at the time, have been credited with reshaping the smartphone industry, and helping make Apple one of the world's most valuable publicly traded companies by 2011.^[22] The original iPhone was the first phone to use a design featuring a slate format with a touchscreen interface.^[23] Almost all modern smartphones have replicated this style of design.
In the US, the iPhone reigns supreme by a wide margin in the smartphone market. "According to recent data compiled by comScore, the iPhone’s share of the U.S. smartphone market now checks in at 43.6%. Following not too closely behind is Samsung with a 27.6% share of the market."^[24] In March 2014, sales of the iPhone brand had reached 500 million devices.^[25] In the last quarter of 2014, there were 74.5 million iPhones sold, a record, compared to 51.0 million in the last quarter of 2013.^[26] Tim Cook revealed at the Apple Watch conference on March 9, 2015, that Apple had sold a total of 700 million iPhones to date.

samsung galaxy note 2

The Galaxy Note II features a 5.5-inch HD Super AMOLED S-Stripe RGB (3 subpixels/pixel) (non-PenTile) screen with 1280×720 resolution, a 1.6 GHz quad-core Exynos CPU, 2 GB RAM, an 8 MP rear camera and 1.9 MP front camera, and a 3,100 mAh battery. It is slightly thinner than its predecessor at 9.4 mm (0.37 inches), albeit also being slightly heavier by 2 grams (0.071 oz). Depending on the specific model, the phone features HSPA+ 21 Mbit/s along with 4G LTE (42.2 Mbit/s DC-HSPA+ for LTE Version).^[20][21][22] The Galaxy Note II is equipped with Broadcom BCM4334 chipset for the IEEE 802.11 a/b/g/n Wi-Fi connectivity in 2.4 GHz and 5 GHz dual-band with maximum rate up to 150 Mbit/s, FM radio tuner and Bluetooth 4.0 + HS support.^[23]
The Galaxy Note II was supposed to be available in 16 GB, 32 GB and 64 GB storage capacity variants, each expandable by up to an additional 64 GB with a microSD card. However, as of 8 January 2013, only the 16 GB and 32 GB versions are available and there has been no release date for or any indication of a 64 GB version of the Note II to be offered

samsung galaxy note 3

The Galaxy Note 3's design was intended to carry a more upscale, "premium" look in comparison to previous Samsung devices. Although it carries a similarly polycarbonate-oriented design to other recent Samsung devices, the Galaxy Note 3 has a faux metallic bezel and a rear cover made of plastic leather with faux stitching. With a thickness of 8.3 mm (0.33 in), it is slightly thinner than the Galaxy Note II, and is also slightly lighter. The LTE and China version of the Galaxy Note 3 (N9005) uses a 2.3 GHz quad-core Snapdragon 800 chip, while the international GSM-only model (N9000) uses an octa-core Exynos 5420, consisting of four 1.9 GHz Cortex-A15 cores and four 1.3 GHz Cortex-A7 cores. Testing has shown similar performance for both models."[20]". The device also includes 3 GB of RAM, a 5.7-inch 1080p Super AMOLED display, a 13-megapixel rear-facing camera capable of filming videos in 1080p at 60 fps and 4K resolution at 30 fps (capped at 5 minutes), 16, 32 or 64 GB of internal storage, and a 3200 mAh battery.^[3][6][7]
As with other Galaxy Note series devices, the Galaxy Note 3 ships with an S Pen stylus, which has been updated to use a more symmetrical shape.^[3][6][7] The Galaxy Note 3 is also the first smartphone to include support for USB 3.0, which enables faster data transfers and charging when connected to a compatible port.^[8]
The Galaxy Note 3 was first made available in black, white, and pink. In December 2013, Samsung introduced three new color schemes for select markets; black with gold-colored trim, white with rose gold-colored trim, and red with silver-colored trim.

samsung galaxy note 4

The Samsung Galaxy Note 4 features a 2560×1440 Quad HD (QHD) WQ HD Super AMOLED 5.7-inch display with 2.5D damage-resistant Gorilla Glass 4, and provides a pixel density of 515 ppi (pixels-per-inch). The Note 4 comes in two variants, one powered by a 2.7 GHz quad-core Snapdragon 805 chipset with Adreno 420 GPU, the other powered by Samsung’s ARMv8-A Exynos 7 Octa SoC with two clusters of four cores; four Cortex-A57 cores at 1.9 GHz, and four Cortex-A53 cores at 1.3 GHz, which is the same processor cluster sold for the Samsung Galaxy Note 3 in markets that mostly use or only have 3G (Such as HSUPA and HSPA), and/or '2G', such as unaltered GSM and CDMA networks, similar to how the Galaxy Note 3 is sold. The phone has metal edges with a plastic, faux leather back. The China model is TD-LTE and TD-SCDMA Plus Network.
Both devices that use 4G, LTE/LTE-A and Hybrid 4G-LTE Networks are currently only sold in Canada, Australia, U.S, U.K (for some carriers), Sweden, Norway, Denmark, and South Korea, which have widespread 4G LTE Markets, or are solely 4G/LTE/LTE-A dependant such as Canada and Denmark, which do not use any 3G or older networks, except for HSUPA (Used as a fall back network should the signal strength be weak due to being underground or in the middle of a building), as well as HSPA+, which is a 3G network, though considered by some to be the Original 4G.^[2][3][4] The GPU in charge in the Exynos chipset is the Mali-T760.^[5] Both variants come with 3GB of LPDDR3 RAM and 32GB of internal memory.^[6] Samsung touted new S-Pen features including tilt and rotation recognition^[7] but these features are either not implemented or not supported.^[8] The Note 4's back-cover has a strong resemblance to the Note 3, with a faux leather texture (although without the simulated stitching). Note 4 has a new aluminum frame design, bearing resemblance from the Samsung Galaxy Alpha. Criticism has been aimed at the lack of IP67 certification (water and dust resistance), which is present in Samsung's other flagship, the Galaxy S5.
The Note 4 features a USB 2.0 charging port instead of USB 3.0 (as was in the Note 3 and S5), in favor of a new feature called Fast Charge, which Samsung claims can charge the phone from 0% to 50% in about 30 minutes and from 0% to 100% in less than 100 minutes. It features some unique sensors such as a UV sensor and heart-rate monitor, oximeter, among other, more common sensors.
The Note 4 also includes a stylus pen seamlessly incorporated into the design

samsung galaxy note 5

The Galaxy Note 5 adopts a similar design and construction to the Galaxy S6, featuring a unibody metal frame and glass backing, although unlike the standard S6, the back of the device is curved.^[8] It is offered in dark blue, white, gold, and silver color finishes.^[8] The storage slot for the S Pen stylus uses a spring-loaded mechanism to eject the pen.^[9]
The Note 5 features a 5.7-inch 1440p Super AMOLED display with pixel density of approximately 515 ppi.^[10] It is powered by a 64-bit Exynos 7 Octa 7420 system-on-chip, consisting of four 2.1 GHz Cortex-A57 cores, and four 1.5 GHz Cortex-A53 cores, and 4 GB of LPDDR4 RAM.^[11][12] The Galaxy Note 5 is available with either 32 GB or 64 GB of storage (a special "Winter Edition" exclusive to South Korea offers 128 GB storage),^[13] and utilizes a 3020 mAh battery with wireless and fast charging support.^[8] Similarly to the S6, the Note 5 does not offer expandable storage or the ability to remove the battery, unlike its predecessor.^[8] As with the S6, the fingerprint scanner in the home button now uses a touch-based scanning mechanism rather than swipe-based, and the device also supports Samsung Pay.^[8] The 16-megapixel rear-facing camera is identical to the Galaxy S6, with a f/1.9 aperture, optical image stabilization, object tracking autofocus, and real-time HDR.^[14]
The Galaxy Note 5 shipped with Android 5.1 "Lollipop".^[8] The new "Screen off memo" feature allows the phone to be awoken directly to a note screen when the stylus is removed.^[8] The Camera app on the Note 5 also allows public and private livestreaming directly to YouTube, and supports export of RAW images
