Behind the glass: a detailed tour inside the Motorola Droid RAZR

At a thickness of 7.1mm, the Motorola RAZR's so thin that you wouldn't think that anything could actually fit in there, but there's indeed plenty of circuitry and silicon crammed into that teeny space. As always, our curiosity was aroused with such a high-profile device, so we once again called upon the talents of Francois Simond (Supercurio) to do some eForensics and clear up some of the mysteries lying between that gorgeous display and tough Kevlar backing. Join us below, won't you?

Note: The list you see below is non-extensive and may grow as we hunt down additional details.

Here are a few of the nuggets we found buried inside the Droid RAZR:


  • CPU: TI OMAP 4430 at 1.2GHz, 2x 2395 BogoMIPS

  • GPU: PowerVR SGX540 (Frequencies not specified)

  • Baseband: CDMA Qualcomm MDM6600 (Same as Droid Bionic, Verizon iPhone 4)

  • LTE: Motorola Wrigley (Same as Droid Bionic)

  • NFC controller: NXP PN544 (Note: the Linux driver is present, but hardware appears to be missing or misconfigured)

  • HDMI: OMAP4 HDMI output with HDCP support

  • RAM: 1GB included, 919MB available to the OS


  • Accelerometer: STMicroelectronics LIS3DH 3-axis

  • Magnetic Field sensor: Asahi Kasei AK8975 3-axis

  • Orientation sensor: Asahi Kasei AK8975

  • Proximity and light sensors: TAOS CT405

  • Gyroscope: STMicroelectronics L3G4200D

  • Barometric pressure sensor: Bosch Sensortec BMP180

  • Temperature sensor: TI TMP105

  • Directional tap / double-tap sensor: Kionix KXTF9 (May be related to the Webtop / LapDock)

Misc. internals

  • Frequency scaler: mot_hotplug (OMAP-optimized)

  • Android: 2.3.5

  • LCD density for Android UI scaling: 240dpi

  • Refresh rate: 60Hz (Maximum window manager events value set to 55fps only; in theory, this could make finger scrolling less smooth)

  • Linux kernel:

  • Screen controller supports CABC (Content Adaptive Brightness / Backlight Control)
