Nexus 5X (codenamed bullhead) is an Android smartphone manufactured by LG Electronics, co-developed with and marketed by Google Inc. as part of its Nexus line of flagship devices. Unveiled on September 29, 2015, it is a successor to the Nexus 5. Nexus 5X along with Nexus 6P served as launch devices for Android 6.0 Marshmallow, which introduced a refreshed interface, performance improvements, increased Google Now integration, and other new features. It is currently one of the few phones that can connect to Project Fi, along with the Nexus 6, Nexus 6P, and the Pixel.
In order to save power, Google has introduced what it calls an 'Android Sensor Hub'. It is a secondary low-power processor whose purpose is to run activity-recognition algorithms by directly monitoring the device's accelerometer, gyroscope, fingerprint reader, and camera sensors, allowing the main CPU to remain inactive until something requires its attention. The Sensor Hub recognizes when the device has been picked up and will automatically display notifications in a low-power white-on-black text until the screen has been properly activated. Additionally, the Sensor Hub stack also supports hardware sensor batching, a feature introduced in KitKat that permits sensors to delay for a short period of time the handoff of non-critical data to the operating system – as opposed to sending a constant stream of data to the CPU, which results in the use of more power. Sensor batching has been used in step counters to avoid requiring the main processor to constantly remain awake for each step to be measured.
The Nexus 5X houses a 12.3 megapixel (1.55 μm pixels) f/2.0 aperture Sony IMX377EQH5 rear camera which is assisted by laser autofocus and dual LED flash. It can record 4K UHD videos at 30 FPS and slow motion videos at 120 FPS. It also has a 5 megapixel front camera.
The Nexus 5X and 6P were among the first phones to use a USB Type-C connector instead of the hitherto standard Micro-USB connector Unfortunately, despite the Type-C connector, the USB port will only transfer at USB 2.0 speeds (480 Mb/s), and not USB 3.0 speeds (5.0 Gb/s). Also, video is not available on this port, so Type-C-to-HDMI adapters will not work. However, USB On-The-Go is supported. Google and LG also made USB Type-C 'Rapid Charging' compatible with the device, claiming up to 4 hours of use in 10 minutes.
The phone originally came with Android 6.0 Marshmallow, which includes "Now On Tap", "Doze" battery saving feature, detailed control of app permissions, and support for Google "Imprint" fingerprint sensor.
In December 2015, Google released Android 6.0.1 Marshmallow for the Nexus 5X, among other devices.
On December 6, 2016, Google released Android 7.1.1 Nougat for the Nexus 5X, as well as several other devices.
Color choices include Carbon, Quartz, and Ice. The body is a hard polymer plastic with the proximity sensor, light sensor, voice speaker on top of display and audio speaker below display, RGB LED notification light under audio speaker, and front facing camera on front of device. The back of the device includes a 12.3 megapixel camera, Google "Imprint" finger print sensor, dual tone flash, and LGE's laser auto focus. One side of the device contains the nano SIM slot and the other includes the power button, and volume buttons. Microphones are on top and bottom of device.
Some Nexus 5Xs in early batches had yellow-tinted screens, which Google replaced.
Some users have reported that the display has touch-sensitivity problems when the charger is connected.
Some users have reported spontaneous unrecoverable boot loops. The issue seems more prominent following the update to Android 7.0. As of November 24, 2016, LG no longer manufactures Nexus 5X motherboards and are offering full refunds for devices experiencing bootloops. As of the same date, no clear pattern among affected units has emerged and no statement identifying affected models has been made by LG.
