The docomo NEXT series ARROWS X F-10D is an Android smartphone manufactured and developed by Fujitsu for the NTT Docomo, brand supporting both 3.9G Xi (LTE) and 3G FOMA networks. It is part of the docomo NEXT series.

The ARROWS X F-10D is the successor to the F-05D and was the first smartphone with a quad-core processor released by a Japanese carrier. While sharing fundamental hardware features with the simultaneous au counterpart, the ISW13F, the F-10D additionally incorporates Xi LTE connectivity and Qi wireless charging support, while measuring 1 mm thicker than the ISW13F.

History

The ARROWS X F-10D was officially announced by NTT Docomo on July 18, 2012, followed by a formal market release on July 20, 2012. On May 8, 2013, NTT Docomo selected the F-10D as a target device for an official Android operating system upgrade. The system software update to Android 4.2.2 was released on November 6, 2013. NTT Docomo officially ended repair services and post-warranty technical support for the device on February 28, 2019.

Specifications

Hardware

The device is powered by the NVIDIA Tegra 3 system-on-chip featuring a quad-core Cortex-A9 central processor alongside a 400 MHz "5th companion core" designed to minimize power consumption during low-demand tasks like standby, settings, voice calls, and text entry. The Tegra 3 platform integrates a 12-core NVIDIA GeForce GPU to support 3D gaming graphics, alongside a 1800 mAh removable battery.

The rear-facing camera features a f/2.4 aperture, 13.1-megapixel back-illuminated CMOS sensor (Exmor R for mobile) co-engineered with Fujitsu's Milbeaut Mobile image processing engine, capable of recording Full HD video (1920×1080 resolution). The front-facing camera features a 1.3-megapixel CMOS sensor. The smartphone meets IPX5 and IPX8 water resistance specifications. Unlike its sibling model, the REGZA Phone T-02D, the F-10D omits Mobacas broadcast capability, allowing it to integrate Qi wireless charging, which was excluded from the T-02D to avoid signal interference during wireless power transmission. Physical connectivity options include MHL output over a shared microUSB terminal for HDMI video delivery, standard 1Seg TV tuning, FeliCa mobile payment compatibility, and IrSimple infrared transmission.

Software

The smartphone originally shipped with Android 4.0.3 Ice Cream Sandwich, featuring Fujitsu's proprietary features such as predictive web browsing, a smart fingerprint sensor, Privacy Mode, milock app lock, Super Clear Voice 3, Pittari Voice, Slowly Voice, Awaseru Voice, Super Double Microphone, IntelliColor, Hold-On Display, Awaseru Zoom, Mindful Ringer, and Slide-in Launcher. The pre-installed software suite includes Health Life Diary (Karada Life), Sukkiri Alarm, Temperature and Humidity Checker, @F Mobile Support, Fujitsu Mobile Integrated Dictionary+, Easy Migration, NX! Eco, and the bundled mobile game Sonic the Hedgehog 4: Episode II.

Software updates

The Android 4.2.2 Jelly Bean software upgrade added lock screen camera activation and lock screen widgets, batch deletion in the recent apps menu, enlarged app icons in Palette UI, folder icon customization up to 9 apps in NX! Home, integrated dictionary lookup within the standard browser, customizable keyboard dimensions and backgrounds, improved UI responsiveness, Google Now, status bar action shortcuts, and Daydream screensavers, alongside Docomo's Data Storage BOX support.
