    Any chance you could make a widget that toggles between 0% and 100% in 1 click? The only time I need to switch brightness is while driving in my car and the sun is shining on the screen.

    how can we get it to work with Hero ROM (yes, Autobacklight is disabled)?

    Any idea?

    Thanx for all the great work!

    I can confirm the widget does not work on the Sprint Hero whether I have the backlight disabled or not.

    Hello Marcus

    Probably HTC something changed in hero rom. But it works on other devices and even emulator.

    I also have the Sprint HTC Hero and noticed the same issue where the backlight would change temporarily, but once the widget is exited the backlight would change back. I did notice though, if using the widget and setting the backlight to a level, then going into “settings, sound & display” it will then move to the level that was chosen in the widget. Not sure if that will help troubleshoot and getting this to work on the Hero.

    I can confirm Jon’s post above. The Sprint HTC Hero does register the change to the brightness system setting, but until I go through the usual system menus it won’t stay active.

    Is it possible to add the ability to turn on auto brightness via the widget?

    saltorio Reply:

    I love this widget, but would also like to request an option be added to the brightness selection option to toggle auto-brightness on/off.

    ManiacalV Reply:

    I agree. I’ve seen plenty of widgets and this one is sleek. The only thing that would make it better would be an option to turn auto back on. I’d even be happy with removing one button and allowing: 0%, 33%; 66%; 100%; Auto.

    Hi, everybody!

    I just installed this app on my HTC Tattoo (1.6 firmware – Donut), but it doesn’t work as expected. I touch the widget and select the brightness, but once selected the brightness settings return to original level.

    Does anyone else happens this?

    bomba Reply:

    Yes also for me!…if you open from the settings->display settings->brightness the brightness goes to the right level. May be is it a bug?

    Have noticed an issue on my Xperia X10: I I choose 100% brightness via this widget (either by pressing the 100% button or selecting it via the slider), the brightness reverts to whatever it was set to previously (ie: the 100% brightness doesn’t take). However, selecting 99% via the slider works fine.

    Timo Reply:

    The same behavior at my Sony Xperia X10.
    The click on the 100% Button set the display brightness to 0%. If I set the Display brightness via build in system setting to 100%, in the widget is shown 99%.
    Can you fix this?
    Maybe you can ask the system which device it is and if it is an X10 use 99% instead of 100%.

    Thanks, Timo

    Has a bug on my Xperia X10. 100% brightness sets the phone to its minimum level of brightnes (it is the same as setting it to 0%).
    And I agree with Phogster: It would be nice to be able to set the widged to toggle x% and 100% brightness with one click (20% and 100% for example)

    Hi, I just installed the widget and added it to the home screen. It worked perfectly fine, until I accidentally clicked 0% which turned the whole screen to black. Now, I can’t see anything. Is there any way to change it back to something else? Is this working as designed or some kind of error?

    Thank you so much!

    What with ‘auto’ option? In general I always use ‘auto’, but sometimes i need for a while switch to 100% (very bright environment) or to minimum (reading ebooks at night). Switching back to auto is my main need.

    Thanks for the very useful widget. Would it be possible to have and additional brightness level (15%) as I normally have a dim screen to save battery, and 25% is a little higher than I usually use. (0%, 15%, 25%, 50%, 75%, 100%, Auto).

    Another option would be to set the brightness level using the slider and then pressing and holding on a specific button would transfer the current brightness to that button (with updated percentage display). This would allow specific brightness levels to be set up on a user-by-user basis.

    I love this app!! It’s the best one out there to adjust the brightness. I agree with woofz in that it would be perfect if we could configure our own brightness level buttons. I will definitely purchase/donate if this feature is added. The pre-configured buttons are not what I would like them to be.

    Please consider adding this feature if it’s possible.

    By the way, I have an android tablet, and this afternoon I pushed 0% button by mistake! Everything disappeared and I had no idea how to get back to normal screen that I can see anything. So I had to reinstall the whole firmware again. So can anyone tell me how to recover from 0% please? Thanks.

    12:29 AM on January 20th, 2011

    Great widget. It could be a bit bigger though, compared to e.g. the native Android widgets (Profiles for example), it looks small.

    I think you could remove the 0% option. It’ll only lead to accidents, gotta be careful when using your widget.

    Still, nice work. I hope you’ll keep it updated.

    Sent from my Samsung Captivate with Perception 10.4, Firebird2 v0.9 #80 Kernel, Firmware 2.2.1, Modem T9000UGJK4. My brightness keeps creeping up as I use my Captivate. 0 is not black, but that is ok. Also, (maybe not your problem), but after turning off, some widgets and icons disappear off HomeScreen(?). All of your widgets disappear, Smooth Calendar widget, small Twitter widget, Trillian IM icon, Opera Mini icon all disappear after turning off my screen or rebooting

    Hi Vladimir,

    Great work, thanks for all your effort. I would wholeheartedly agree with a couple of other posters in that I’d love a toggle just between 0 and 100% brightness. Might it be possible to include this even as a separate widget in the pack so that people can maintain the customisability of the current version, but also be able to toggle the absolutes if they wish? The simpler the better I think, I wouldn’t want any options at all tbh, just a toggle between 0 and 100, or maybe to be safe, 1 and 100 to prevent the black screen problems some people have? I’d love to know your thoughts.

    Keep up the great work!

    I like this widget and it works great, but can you make the brightness levels configurable please? On my HTC Desire S, 0-25-50 are much bigger jumps in brightness than 50-75-100, so I’d like to be able to configure something like 0, 15, 30, 50, 75, 100.

  44. Lawrence Aubin
    5:18 AM on April 25th, 2011

    Can you make it so we can set our own percentages for presets? This ability would make the app perfect and then it’d qualify for 5 stars in the Android Market. Please let me know if you can do this…

    Hi Vladimir, I sent you an email about this problem, but did not hear back from you, so I am posting here.

    I installed Brightness Level widget on my htc evo, and immediately started having the following problems with the display. The problems continue, even after I un-installed the widget:

    1. The status bar “flickers”, for lack of a better way to describe it…it is as if it is continually being swiped up and down, and at times it moves down completely all by itself with no input. Sometimes items in the status bar list are selected, also without any actual input from me. This “flicker” interferes with attempts to input via swipes, touches, etc, in any other area of the screen, including softkeyboards, etc.

    2. Sometimes the status bar is “frozen” and does not respond to a swipe, even though the rest of the screen responds normally.

    2. The entire display periodically “freezes”, and does not respond to any touch. This has even happened during an incoming call, preventing me from answering the call.

    Please advise me on how to COMPLETELY REMOVE this widget, and/or whatever code installed by your widget is causing this. If you respond here, please also notify me via email of your response. Thanks….

    Does the phone have to have an automatic brightness setting for this to work or will this create one? I am looking for an auto-brightness setting but it doesnt seem that my phone has that. It just has a power saving widget that goes from zero to midlevel to 100% brightness. I was looking for something to auto-bright depending on the surroundings…but from the description, it seems like this will only put a toggle widget on an existing phone function.

    Toggles ftw > more clicks. How about a widget that you are able to define the 3 settings it rotates through when you click it on the home screen. That was I could have 15%, 25% and Auto rotating on a click. I’d be willing to help with whatever basic assistance I could provide.

    Dear Curvefish,

    I have a NATPC M009s 7″ tablet on which I have installed your brightness level app as I did with an android phone, unfortunatly I set it to 0% brightness, whereas with the phone this dims it down but is still readable with the tablet it has blanked the screen completely so I can not see the icon to adjust the brightness up so i can see it!

    The android logo comes up when i power up and down but then the screen goes “blank”

    I have tried reset and have done a lot of blind tapping on the screen to no avail, could anybody suggest how I can get my screen back?

    All help greatfully received!

    Many thanks.

    I have an iRulu Knightpad and used the Brightness Widget. it works great except, when i hit 25% brightness, it made my screen go completely black. I cannot reset it because i can’t see anything. after Model Logo and Android Logo on boot up, screen goes dark. if i hard reset, the screen flickers for just an instant which tells me behind the black screen, my tablet is still operating. I don’t know what to do at this point. since i already rooted my device, my warranty is void. i cannot return it to the manufacturer. is there any advice you can render?

    Is it possible for the Auto setting to use only between A% and B%, where “A%” and “B%” are controlled by sliders? I never use auto, cause it’s always brighter than it needs to be.

    E.g. I would use Auto between 10% and 60%, but between 0% and 100% has the ends on the scale either too dark or too bright.

    Feel free to contact for more info and thanks for an amazing set of apps!

    The widget is great.

    But on my Motorola Atrix 4G I usually set the brightness level to 8%.
    If I change it to 75% because I am outdoor with sunshine I have to use
    the slider to get back to 8%. That’s a little bit complicated.

    A configurable button with a percentage value which I can define by myself
    would be prefect.

    Love your app.
    On some AOSP ICS roms (I had tied) I did encounter the following:
    Initially the app works fine, but after some time (even after several reboots) , it stops chnging the brigtness levels when pressed. The change to brightness only occurs when after one chosses a level, the effect takes place only after the screen is turned off and then on again.

    Please advice

    I find this brightness invaluable. It was the first app that I ever purchased on Android and still the most useful.

    I have one suggestion: On my phone the brightness does not seem to be linearly proportional to the percentage setting. I would find it more useful if the presets were 0%, 12%, 25%, 50% and 100% as I never use 75% and often use the slider to set about 10 to 15%

    Thanks for a great little widget :)
