[Q] Car install - Volume Softkeys ? - Nexus 7 (2013) Q&A

Looking for a way to add volume softkeys. see pic attached.
I have GMD GestureControl and Volume in Notification as a bandaid for the time being.
indash install is 95% complete and will be posting a complete walkthrough of it installed in my 2007 honda element.

you could install a custom rom that allows widgets into the nav bar.
id assume there are other ways to do this too. cool setup. I want to put a tablet in my car like this when I upgrade vehicles.

The screen brightness even at the dimmest stock value was almost the end before the start until I was reccomend to try lux from the play store. It lets you go way under the stock brightness resulting in a perfect night driving whether you want it dim to keep less distracted or dim to play video that's much less noticeable from outside

[HOWTO] Turn off screen (kind of) while recording.

So I know a few people have asked about this around the net and I've yet to find a solution for this so I thought I'd post my little workaround.
Anyone that's tried to create a long timelapse with the GNex will tell you 1) you NEED to be plugged into AC the whole time and 2) Phone gets extremely hot. Since brightness is automatically increased when recording video, and can't be decreased I use the following combo/setup as a workaround.
Download Screen Filter from Market (**** a play store) https://play.google.com/store/apps/details?id=com.haxor&hl=en
This app essentially lets you tint your mobile screen from a percentage range of 2-98% of your current brighthness.
Once the app installed go into drawer and add the apps widget to one of your home screens, and set your desired tint percentage. I'm currently at 2% and that makes my screen look like its completely off (except for softkeys)
The final product ends up looking like this..
lol and for all you pervos out there dont be using this workaround to secretly record down/up women's clothes and such...
there is a spycam app called simple notepad that will give you a complete black screen while recording and lets you take pictures by tapping the screen. it works great with amoled scene since the phone looks like it's off when there is a black background. it'd didn't work so good on my atrix but great on the captivate. It's not in the market so you will have to google it.
thanks for the tip I'll check it out

but how can you do anything after recording has started? my phone stops recording even if i press the home button.
or do you darken it before you start recording, and then navigate blindly? how do you undarken it afterwards?
hmm... the screen filter idea seems kind of good, even though you have to navigate blind through the menu... I wish there was a native way of achieving this, just like a button in the camera to turn the screen off and back on again on a tap somewhere or so... But I think it works for my problem, thank you for your idea.

How to dim the GN screen even more?

I find the dimmest screen toggle still too bright. I find it embarrassing to use in dark public spaces.
Is there a way to dim the screen even more?
Download the screen filter app from the play store. Literally puts a filter effect on the screen to make it appear darker making it much easier to use in the dark.
Yes its possible to take the screen much lower, but we have to edit the framework. Nobody had done this mod yet for some reason.
CM9 has the ability to change the screen lowest settings built in

+1. I use Screen Filter also, it's uber handy for reading at night when the light seems too bright. If you've got hardkeys like I had on my Desire, you can even turn them off.
i wrote a tutorial on how you can mod the frameworks apk. it's very easy and you can change the brightness levels to anything you want. here's the thread
screen filter only puts a transparent layer on the screen and messes with the colors. modding the frameworks will lower default brightness to any level you want. you can raise it too if you like.
Thanks for all the ideas. I went with the easiest one, Screen Filter.
AOKP also has an option to reduce screen brightness...

Great work, I've been wondering why nobody did this mod yet for the nexus. I made that same mod on my atrix, using the sgs2 thread as well. But I've been too lazy to do it for nexus.
The above mod is the best option. Screen filter doesn't achieve the same results. The above mod reduces power draw as well when on the lower brightness setting of 5 or so. Screen filter just hides the higher brightness but has same power draw.

That would be correct for back-lit screens. For the Galaxy Nexus screen, though, Screen Filter does help reducing power draw as a darker screen content = lower brightness.
I used to use SF for quite a while until I got fed up of it causing stutters to most animations. After thorough examination I concluded that the Nexus's GPU is the culprit. For some reason it just doesn't like multiple graphics being updated at once. Modding the overlay XML allows it to run at full speed.
Can anyone confirm the same reduced framerate issue?. It's also the reason why some ROMs include a setting to remove the navigation buttons glow. I tested with CM9 on the SGS2 and experienced none of the stutters in cases where the GN would. Another example: sliding between sections (comments, ralated, etc.) in YouTube is laggy iff the video is playing.

Agreed, GPU just isn't good enough. I hate the lag with the button glow animations on!
I use an app called root dim, it's really useful. Let's you use a brightness level of 1, which is really quite dim. Free, too.

Thanks for the tip, on the Galaxy Nexus it's possible to set the brightness to 0 by writing to /sys/class/backlight/*/brightness but the brightness is checked and reset to the minimum (default 10) every time the screen is turned on. I guess Root Dim works to the same effect so it runs as a system service. Still, it'd be an awesome addition for people who haven't bothered to mod.

Screen filter may reduce power. But amoled screens save power with lower brightness. There is no difference between lcd vs led on this issue. And modifying the framework to bring min brightness down to 5 rather than 15 saves much more power than screen filter. Its no contest. This isn't different from lcd in this case.

Yes we can write to that sysfs file, but it gets reset. The mod to the frameworks incorporates that backlight file so its now able to go down to 1, 2, 5, or whatever you want. It makes it now stock, so you are no longer capped at 10 (actually I think 15 is the cap I see). But that mod is just removing this cap and making it lower to whatever you want. Stock.
So no extra app is needed. No additional tweak. It now makes the stock brightness able to go down to 1 by itself whenever it needs.

Display Brightness App

I posted this before when all the SGS3 variants were under one forum. Now that they're locked, I just wanted to post this here as I know a lot of people liked the app. I use it everyday.
One thing I definitely miss on SGS3 coming from SGS1 and SGS2 was the ability to change the brightness setting from from the top of the notification bar. You were able to slide your finger left to right and be able to change the screen brightness.
Display brightness can do something similar and thought I'd share as I am sure a few of you might also miss the old feature. You can set a screen brightness slider anywhere on the screen and change its transparency. It works a treat to be able to change brightness quickly and efficiently. I set mine to be on the left side of the screen horizontally, and set transparency to 0 so it cannot be seen. Then when I need to change brightness quickly, I just slide the bar up or down. There are quite a few options and different sizes you can choose. Also, you can set it so that there is a one second delay. This helps to avoid touching the bar by accident and changing brightness on you.

Have it installed and really like it.
One problem I'm having is that I set it to Enable the Indicator on my screen, and it periodically turns off. A bit frustrating. But other than that, it's great.

I get the error trying to install apps every time I flash cm10 and then go back to stock. If that's the case youd notice it trying to install other apps on the market. Either case it's a market problem or the rom you're on. I normally fix by clearing market data as well as google framework data too. Then reboot and I can install apps again. It doesn't sound like an app problem though
Also the indicator shutting off I have not seen before. That could be a result of task manager app or something shutting it off somehow

I thought about that. If so, it is the system manager, because I do not run task managers.
I do have System Tuner...have nothing set in it's killer. I did set this app as excluded (which my understanding is that excludes apps from availability to kill). I think maybe it did help, but did not cure the issue.
Ultimatum rom lets you change brightness from the top. However the min brightness doesn't go low enough on this phone. Too bright in dark rooms

I use another app called screen filter for the darkness issue. Check it out! You can then make the screen MUCH darker depending on preference. I agree, the screen does not go low enough on this phone especially at night when in a dark environment.

[Q] Set Default Dim to 50%

I have the opposite issue from most users that want the screen to dim very low. I am using the Galaxy Tab S as a kiosk and would like the default dim level to only go to 50 or 60%.
This seems like it should be a simple change of a file but I can't find anything that will help (No app or Google search). I looked in the Build.prop this was not in the file ro.lcd_min_brightness so I added it but it did not help.
I have not found a app that will help me set the minimum dim level they all need to be done by a button push I need this to be automatic.
As a kiosk the display will dim to 50% then when a user touches the screen the screen will go to 100% after 10 minutes it will dim back down again to 50%.
Thank you
Raymond

Samsung Galaxy Tab S
CyanogenMod 11-2015101-Unoffical-nvertigo-changallwifi

Would the Xposed Module work to dim the screen to 50%?
I found this module Sense 6 Lockscreen Mods [KK] which talks about "Adjust Background Dimming"
Thanks
You might be better off with an lcd display, an oled display is not really suited to 100% brightness for 10 minutes numerous times a day, even if the rest of the time it is at 50%, you card just asking for burn-in damage.

These are the unites we have on hand. I also have an attract screen so burn-in should not be too bad we had to deal with burn-in for years with the old style monitors. I need to lower the display screen to 50% because if it stays at 100% the unit gets too hot and the battery does not charges because heat is causing higher resistance.
Is there any way to set the minimum dim level? would Xposed work using the module Sense 6 Lockscreen Mod? I have been looking and can't seem to find the file(s) that set the minimum dim level.
Thank you
It`s a pity somebody could not make an app for you, try some android app write software, with millions of android apps out there it must be relatively easy to make them.
But keeping the tablet awake and the brightness at 50% until somebody touches the screen then boosting the brightness to 100% and keep the screen on till, no touches have been reported for the next 10 minutes and then reduce the screen brightness back to 50% and wait for the next input.

The brightness issue is the last thing I need to get working. I have an app that puts the tablet at fullscreen with no access to the systems nav and I have an app that will keep the screen on and will allow the system to go to sleep (set time in the sytems settings) but when it goes to sleep the dim is too dark and the tablet looks like it is off. All apps that I have found do not adjust the tablet minimum setting, thel y are all activated by some type of manual input.
Again any help or pointing me in the right direction would be greatly appreciated.
Sorry but i am a bit brainless when it comes to things like that.
But i do have some advice, ask for an generic android app that will do what you want, not in the Samsung section, but in the general xda software/app development section wherever that is but their must be one, have a look though the xda main forum section, pm a mod and ask for directions.
The more specific to an brand and model the less help you will get, you want an general android app, that works on anything, not something that only works on the Samsung Tab S
Good Luck

Control watch brightness by swipe gesture from every screen

Check out this demo video:

For me one of the most useful apps since the huawei watch has no sensors.
Its a little bit tricky at first, but with a little bit of practice, this will work fine. Dont forget to set the correct possition fields in the smartphone app.
Works like a charm.

Thanks, what an awesome little app! Since you've played with it more, what are the smaller boxes at the top and bottom of the position screen are for? Ideally I'd like the slider to work across the top of the watchface, but I haven't been able to figure that out yet.
Also, in your video, you say you can customize it to show the percentage or not. The percentage shows for me, but I don't see any options to customize it at all.
No go here, installed and I can turn the brightness down but not up again. To make things worse, a cold reboot is needed to get viewable brightness (aw 1.5 stock)

It's cool but I feel it's just faster to press the button 3 times to temporary increase the brightness. Hopefully there's a light sensor on the HW2..

Not that i know of. Mine's completely stock, btw (v1.5).
EDIT: just so we're clear, you're not tapping on the screen, are you? I was referring to the metal button on the side. Press that quickly 3x and it'll increase the brightness.

Thanks, it does work after all. There just wasn't much difference with my watchface to notice the difference.
this was a good app recommendation ...
great app, and it goes darker then brightness 1 so already removed the other app I used for bedroom use
