    Galaxy s2 and Google nexus has Bluetooth Low Energy modules built in, but BLE is not enabled. For example, Galaxy s2 specs says it has Bluetooth 3.0, not 4.0.

    Is there a reason for this? Is it because android does not support this feature?
    Motorola RAZR does have Bluetooth low energy.

    It would be great if someone can shed some light on why android devices does not have much BLE devices.

    I've moved this to the Android Lounge so it gets some attention. It was being missed in the FAQ section. :)

    The galaxy nexus uses NFC:

    Bluetooth technology (2.45 GHz) and Near Field Communication (NFC 13.56 MHz) may both be used as short-range communication technologies. However, allowed transmission power for NFC 13.56 MHz is strongly limited implying short range, whilst Bluetooth technology has a range that reaches up to 100m, depending on its class. Integration with mobile phones is increasing, where Bluetooth technology is already part of almost all phone types. Bluetooth low energy technology set-up time has been designed to be faster than Classic Bluetooth technology.
    There is no aim to make Bluetooth technology's WPAN implementation compatible with passive RFID. However, Bluetooth technology defines a well standardized new class of active RFID which requires comparably lower power consumption than NFC in passive read mode, due to different physical coupling: far field is used for Bluetooth technology, whilst near field/inductive is used for NFC.

    I hope this helps unless this is one of those
