Micromax A70 has a MAGNETOMETER AND AMBIENT LIGHT SENSOR FOR SURE!!

    Actually we found this in the engineer mode
    U can get into engineer mode by dialing *#*#8888#*#*
    In Engineer mode mastermind found some mysterious things

    Screenshots
    [​IMG]


    See this screenshot
    It shows magnetic sensor is enabled
    But i guess it is disabled originally in the kernel(we will need kernel source to enable it)
    Also the Light sensor is disabled and word 'not work' is written.
    So we will need kernel source to enable that also.
    [​IMG]

    Also see the first option
    This also proves presence of ambient light sensor

    Second mystery
    [​IMG]

    Now see this image
    In this image u see 'Touch panel' as disabled but as we all know that touch is working
    This means that there is something in our stock ROM that need touch panel to be disabled and then only our stock ROM gives us touch and that's why i guess other ported ROMs won't give touch because they need it to be enabled.
    So mastermind tried to enable it and rebooted but after rebooting it was still disabled that means kernel has it disabled and thats why it gets disabled.
    So we will need kernel source to enable it

    So friends conclusion is that we cannot proceed with further development until and unless we get the source.

    Credits go to mastermind because he discovered the engineer mode and all above things

    Hi
    1.) there that is pretty interesting though what exactly does a tick mean ?
    2.) i think we must run the same thing in A75 and see ... as the device has magnetometer enabled
    3.)more over plz try this stuff :
    change property "ro.build.CONFIG_BUILDTYPE_SHIP" in /system/build.prop from 1 to 0
    in build.prop
    then try Type these codes in phone dialer:

    *#*#307#*#* Enable engineering apps in launcher
    *#*#308#*#* Disable engineering apps in launcher

    like :

    Calibrator
    CDMA NAM Programming
    Dev Tools
    EMList
    Log Master
    Neocore
    OOD_OOM
    Qualcomm Settings
    QVTester-04
    Spare Parts
    VerificationSuite

    This enables engineering apps in Launcher !
    change the prop then restart and confirm then dial the code
    try on Default launcher btw

    Not tested in A70 -- just try may be it works for a70 also
    4.)Just found this one try these if they work - just try the ending codes
    lik bluetooth test etc
    5.)

    Friends!!
    Do u want one more proof for the presence of Ambient light sensor
    Then open root explorer and go to
    system/etc/permisions and open 'android.hardware.sensor.light.xml' file now u will see the permissions are given there for the ambient light sensor
    Then why this file is here? That means that we have at least ambient light sensor 101% and it is locked in the kernel
    We have to get kernel source any how to enable theses sensors.
    Friends its hopeless to fight with mmx now bcoz what they are gonna do if they don't have it.
    Now we should start spamming the BYD Fb wall.
    Come on friends gather and lets start the campaign once again

    @gouthamb
    Now i wanna tell u that consumer forums cannot do anything bcoz i think mmx don't have sources.
    Now we hould start posting on BYD wall

    wow ! if that is the case it is surely a gr8 case . though we cannot locate any specific sensor for the ambient light may be camera on top may be used for the same ... just guess but source code is surely needed now !
    and ya +1 for the BYD thing.

    @ninad
    The light sensor is not located inside camera
    just see these pics
    [​IMG]

    Friends u cannot see the light sensor and other on ur phone directly.
    to see it, go under bright sunlight u will see 3 more circles.

    Will try to find the proofs for the locked RAM now!

    Locked RAM i bet it...!! but u9 s320 users even they weren't able to unlock or find it...!! they also have 190mb RAM usable we gotta do something with this fellas

    If anyone wants to read officially all about u9 s320 here it is.... They have mentioned of RAM and they too are confused why it shows only 190mb RAM.....!!

    Yeah but they don't know its power to full potential it has got. Eg : They still don't have working flash in their phones and we have got 10.3 working..!! well thats a cool one no?

    @varun thanks for those pics i never had that closer look at those !!
    yup got the location of Proximity sensor any ways !! and ya one more thing as far as other droid devices are concerned the magnetometer is located at the side of the device ( left or right ) and in the middle down !
    Hey but what if the device had a LED also ! ;) just kidding !

    I believe this phone doest have the Light sensor hardware ! The 2 dots are infact Proximity Sensors! you see these settings possibly because android has it! The phone doesnt !

    Not in all android..i told my frnd 2 try it n it dint wrk ..so v hav hope for having des sensors..

    hmm its very inersting !
    The first 2 dots from right side ( on varun's pic are both proximity sensors ) and the big one is ambient sensors ...
    I think this coz in nokia 5233 proximity sensors have two holes !

    i think the ram left free is 190mb ... Butnot sure.

    @all
    Open this xml 'handheld_core_hardware.xml' using notepad++ or wordpad. It is located in system/etc/permissions
    In this let me point out some lines
    Code:
    <permissions>
        <feature name="android.hardware.camera" />
        <feature name="android.hardware.location" />
        <feature name="android.hardware.location.network" />
        <feature name="android.hardware.sensor.compass" />
        <feature name="android.hardware.sensor.accelerometer" />
        <feature name="android.hardware.bluetooth" />
        <feature name="android.hardware.touchscreen" />
        <feature name="android.hardware.microphone" />
        <!-- devices with GPS must include android.hardware.location.gps.xml -->
        <!-- devices with an autofocus camera and/or flash must include either
             android.hardware.camera.autofocus.xml or 
             android.hardware.camera.autofocus-flash.xml -->
        <!-- devices with WiFi must also include android.hardware.wifi.xml -->
        <!-- devices with limited/gestural multitouch must also include
             android.hardware.touchscreen.multitouch.xml -->
        <!-- devices with full multitouch must also include
             android.hardware.touchscreen.multitouch.distinct.xml -->
        [B][COLOR=Red]<!-- devices with an ambient light sensor must also include
             android.hardware.sensor.light.xml -->[/COLOR][/B]
        <!-- devices with a proximity sensor must also include
             android.hardware.sensor.proximity.xml -->
        <!-- GSM phones must also include android.hardware.telephony.gsm.xml -->
        <!-- CDMA phones must also include android.hardware.telephony.cdma.xml -->
    And we have that light sensor xml in the permissions directory
    So if the device wont have the sensor then that xml should not be present, isn't it?
    So
    @insane_subro and sunil
    Do u have any objection on this?

    yes, the original U9 S320 might have an ambient light sensor and which may have been discarded for our mmx a70.. remember u9 also has 3.2 MP camera but ours doesnt

    It would have thrown error in compilation perhaps if any unsupported xml is added but it didn't..

    So, I'm with varun on this...
  18. samrox144

    samrox144 Disabled

    +1

    it is not working because it not configured in the kernel
  19. samrox144

    samrox144 Disabled

    JUST TO PROVE THAT IT HAS LIGHT SENSOR

    here is the config.gz of kernel

    CONFIG_LIGHTSENSOR is not set
    CONFIG_SENS CONFIG_SENSORS_PCA963X is not set
    # CONFIG_SENSORS_MT9T013 is not setORS_AKM8976 is not set

    Hey and have a look at this :
    http://www.droid-developers.org/images/b/b2/AK8973.pdf



    More over it is 3- axis magnetic compass !!

    that does mean that it can surely perform as a gryo (3d) sensor. ....
    It is the official data sheet :p of the same
    lol, that is like 101% proof !!!
    mmx is gonna get kicks when they release K.source
