    Any fix for this on Cyanogen? Happens to me on two Dincs. I tried this with no luck:


    Menu>Settings>CyanogenMod Settings>Display>Automatic backlight


    Light Sensor filter
    Enable check
    Window length 60s
    Reset threshold 800 lux
    Sample interval 2s

    Light levels
    Use custom check
    Screen dim level 20 (default)

    Edit other levels...
    0 30
    85 45
    160 55
    193 60
    225 75
    273 80
    320 82
    480 84
    640 86
    960 88
    1280 90
    1940 92
    2600 94
    4200 96
    5800 98
    6900 120
    8000 150
    9120 175
    10240 255
    (buttons, the first two are 255, all others are 0)

    Allow light decrease check
    Decrease hysteresis 50%

    FINALLY found settings that work.

    Reduce the number of levels to 16 and use:

    75, Button 255 with the rest 0.
    77
    79
    81
    83
    85
    90
    95
    100
    110
    120
    130
    140
    160
    200
    255

    Set Window Length to 5 secs.
    Sample Interval to 1 sec (optional)

    Edit: Lowered them a bit.

    What light levels did you assign those brightness levels to?

    Left them as they were above but last 3 removed (just change to 16 levels) so last is now 6900 to infinity. Don't know if there are better ones but these work fine. I don't know why on earth they used 60 secs for Windows Lenth. That's far too unreponsive.

    Basically, you'll get 25% at night, 50% indoors and 100% outdoors with a 5 sec response time.

    Some guy on xda posted these. Work great. Just set Window Length to 5 secs. Columns are reversed:


    These are the settings I have been using for CM7. They work well for my 45 year-old eyes. As always YMMV

    Moving average filter enabled
    Window length: 20 s
    Reset threshold: 800 lux
    Sample interval: 2 s

    Use custom light levels

    Edit other levels...

    Number of levels: 23

    50 0
    68 25
    70 37
    72 55
    74 80
    76 115
    78 170
    80 235
    82 330
    84 460
    86 650
    88 930
    90 1290
    92 1860
    94 2610
    98 3440
    106 4200
    120 4800
    140 5350
    160 5810
    180 6300
    210 7000
    255 8010

    Buttons are 255 through 1st 8 levels (backlight ≤ 80)

    Allow light decrease
    Decrease hysteresis: 50%

    The levels corresponding to the raw sensor output (10, 160, 225, 320, 640, 1280, 2600, 5800, and 8000) are all bumped up by 10 (15 for the 10) to force the lower light level. Extra levels help smooth the transitions.

    If you find these to dim, bump the backlight levels below 120 up by 2 or 4. To bright, bump 'em down.

    23 levels can be a PITA to set up, but it's worth it to me.
