The Nexus 5 is a smartphone co-developed by Google and LG Electronics that runs theAndroid operating system. The successor to the Nexus 4, the device is the fifth smartphone in the Google Nexus series, a family of Android consumer devices marketed by Google and built by an original equipment manufacturer partner. The Nexus 5 was unveiled on 31 October 2013, and released the same day for online purchase on Google Play, in selected countries.
The Nexus 5's hardware is similar to that of the LG G2, with a Snapdragon 800 system-on-chip (SoC), and a 4.96-inch 1080p display. The Nexus 5 is also the first device to featureversion 4.4 of Android.
Release
The Nexus 5 was initially released for ordering at Google Play Store on October 31, 2013, in 16 GB and 32 GB versions.[9]
Specifications
Hardware
The exterior of the Nexus 5 is made from a polycarbonate shell with similarities to thenew Nexus 7, unlike its predecessor, which used a glass-based construction.
Its hardware contains similarities to the LG G2; it is powered by a 2.26 GHz quad-coreSnapdragon 800 processor with 2 GB of RAM, either 16 or 32 GB of internal storage, and a 2300 mAh battery. The Nexus 5 uses a 4.96-inch (marketed as 5-inch) 444 PPI 1080pIPS display, and includes an 8-megapixel rear-facing camera with optical image stabilization (OIS). The Nexus 5 supports LTEnetworks where available, unlike the Nexus 4 which unofficially supported LTE on AWSBand 4 only with a hidden software option, but was not formally approved or marketed for any LTE use.[10][11]
There are two variants of the Nexus 5; one is specific to North America (LG-D820), and the other is designed for the rest of the world (LG-D821). The differences between these two variants are in supported cellular frequency bands; see the infobox on the right for more details.[10]
Like its predecessor, the Nexus 5 does not have a microSD card slot,[12] while it features a multi-color LED notification light.[7] Despite the fact there is a pair of speaker grilles present on the lower edge of the Nexus 5, there is only one speaker; one grille is for a speaker, and another is for a microphone.[5][8]
Notable new hardware features also include two new composite sensors: a step detector and a step counter. These new sensors allow applications to easily track steps when the user is walking, running, or climbing stairs. Both sensors are implemented in hardware for low power consumption.[4]
Software
Nexus 5 is the first Android device to ship with Android 4.4 "KitKat", which has a refreshed interface, improved performance, improved NFC support (such as the ability to emulate a smart card), a new "HDR+" camera shooting mode, native printing functionality, ascreen recording utility, and other new and improved functionality.
Nexus 5 ships with Google Experience Launcher (GEL), a redesigned home screen which allows users to access Google Now on a dedicated page, and allows voice search to be activated on the home screen with a voice command. Unlike other features of Android 4.4, GEL is not technically part of Android; it is technically a component of the Google Search application. As of November 2013, GEL is exclusively shipped on Nexus 5, and is not enabled in the Android 4.4 updates for any other Nexus device. However, an update to the Search application containing the launcher's code was distributed for other Android devices – but the launcher itself cannot be enabled without installing a secondshim application.[13][14]
Hangouts, which now supports text messaging, is used as the default text messaging application.[4][15]
Known issues
- After the camera was unfavorably compared with other high-end smartphones, Google said that software is to blame, and has promised a fix in the coming weeks.[16]
- It has been speculated that poor audio quality could also be a fixable software problem. Google is working on fixing this issue.[8][17]
- Some devices show hissing, popping, loud static, and very low volume with the built-in microphone.[18]
- The headset microphone input volume is very low. Google said this is a software issue and they are working on it.[19]
- There is a problem with the camera capturing solid green or black photos, seemingly caused by the face unlock operation. Also may be caused by using Google Goggles. Google said the issue is fixed and pending for a future release.[20]
- The Wi-Fi can crash when trying to automatically connect to a network.[21]
- When calling a busy number, terminating the call is not possible on some carriers.[22]
- The barometer driver hangs and kills accelerometer on its way. A reboot is needed to make them work again. Google is aware of the issue and working on a fix.[23]
- On some units, the buttons audibly jiggle when the phone is shaken.[24]
- While changing the volume using the volume rocker with a headset connected, system notification sound is played through both the speaker and connected headset.[25]
- When using only slide to unlock, a missed call unlocks the phone until the auto-lock timer kicks in.[26]
