Samsung Galaxy Note II

In December 2012, Samsung began rolling out an update to Android 4.1.2 "Jelly Bean" for the device.[16] In April 2014, Samsung began rolling out an update to Android 4.4.2 ''KitKat'' for the device.[17] Samsung Nordic has stated several times, including on their official page that both the 3G and 4G versions of the phone will get the Lollipop update.[18][19][20][21]

The Galaxy Note 2 is able to show two applications at the same time with flexible width on the screen with its split-screen feature. However, support of this feature varies per app.[22][23]

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 Cortex-A9 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).[24][25][26] 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.[27]

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.

The smartphone's pressure-sensitive S Pen is slightly thicker than in the original Galaxy Note, and a feature marketed as Air View allows a user to preview content by hovering the pen over the content, similar to the hoverbox feature of a mouse in some desktop computers, such as thumbnails in the gallery and a preview tooltip on the video player's time seek bar, and zooming in the Internet browser (Samsung S Browser)[28][29] and for scrolling.[30] Another feature marketed as Quick Command reveals a list of available commands at the swipe of the S Pen.[24][31][32][33]

The S Pen's 1,024 levels of pen-pressure sensitivity give it significantly more accuracy and precision than the original Note's 256.[34][32][33]

Both front and rear camera use the same hardware as used in the Galaxy S3, with eight megapixels (3264×2448) rear facing camera and 1.9 Megapixels on the front facing camera.[9]

The video resolution of the rear camera is 1080p at 30 frames per second while the front camera films 720p at 30 frames per second.

The Galaxy Note 2 is able to capture 6 megapixel (3264×1836) images during 1080p@30fps video recording, which is the highest 16:9 aspect ratio resolution supported by the 4:3 image sensor, matching the aspect ratio of the video.[9]

While the camera interface resembles that of the Galaxy S3, slow motion mode (720×480 at 120 frames per second) has been added. The slow motion videos lack audio.[35]

The burst shot mode is able to capture up to twenty full-resolution photos per row at around six frames per second.[36]

The Galaxy Note II is available in Titanium Grey, Marble White, Martian Pink, Amber Brown and Ruby Wine case colors. Some features were removed, which vary as customized by carrier, include FM/TV tuner, charging pins, and Multiple-SIM card support. To prevent grey market reselling, models of the Galaxy Note II, and other models (Galaxy S4, Galaxy S4 mini, Galaxy Note III and Galaxy S III) manufactured after July 2013 implement a regional lockout system in certain regions; requiring that the first SIM card used on a European and North American model be from a carrier in that region. Samsung stated that the lock would be removed once a valid SIM card is used.[37]

The baseband chipset of GT-N7100 is Intel Wireless PMB9811X Gold Baseband processor.[38] The baseband chipset of SGH-T889, SHV-E250K, and SHV-E250S is Qualcomm Gobi MDM9215.[27][39][40] SHV-E250L has Qualcomm Gobi MDM9615M for the EVDO revision B connectivity.[41]

• GT-N7108D is a version similar to GT-N7108 but with LTE-TDD support. Also the Qualcomm Snapdragon SoC was used in this version.

Only some Galaxy Note II variants have a built-in FM radio tuner. For example, some US and Canadian variants (SGH-i317,[43] SGH-i317M[44]) and the LTE International version (N7105) lack the FM radio tuner support.[45] SC-02E for Japan market has 1seg digital-TV tuner and antenna.[46] Korean variants have the T-DMB tuner as well as the T-DMB antenna that can be concealed in the phone body.

Korean variants with the T-DMB tuner and the T-DMB antenna are 3 g (0.11 oz) heavier than other variants. SC-02E for NTT DoCoMo with 1seg TV tuner is 5 g (0.18 oz) heavier and 0.3 mm (0.012 in) thicker.[47]

Depending on the model, some Galaxy Note II (GT-N7100) units have the two optional charging pins on the back side of the device, just right of the battery holder, that can be used for wireless charging with the dedicated wireless charging back cover variant. Galaxy Note II displays the notification message built in the firmware when it is charged wirelessly. SCH-L900 does not have the pins. SGH-T889 has the pins, but they are disabled.[48]
