SD card interface
The SD card connector is mounted on the user interface PWB. The SD card is supplied with 3 V supply voltage.
The detection of the SD card removal/insertion is done by a switch in the card connector. Removing the SD
card while writing to the card may corrupt data in the SD card.
Battery interface
The battery interface supports a 3-pole battery interface. The interface consists of three connectors: VBAT,
BSI and GND.
The BSI line is used to recognize the battery capacity by a battery internal pull down resistor.

Battery temperature is estimated by measuring separate battery temperature NTC via the BTEMP line, which
is located on the transceiver PWB, at a place where the phone temperature is most stable.
For service purposes, the device SW can be forced into local mode by using pull down resistors connected to
the BSI line.
Camera interfaces
Back camera interface
The back camera of the device uses a 3.2 mega pixel camera module with auto-focus, mechanical shutter
and neutral density filter, producing pictures with a resolution of up to 2080x1560.
The regulators N9006, N6518, N6513 and N6517 power the graphics accelerator (D6500) and the camera.
Camera construction
This section describes the mechanical construction of the camera module for getting a better understanding
of the actual mechanical structure of the module.
