[APP][ROOT]ScreenToggle - turn off your screen (e.g. while plugged into hdmi)

Wanna turn your Screen off while watching videos over HDMI?
Or need a watchful Xoom but don´t want the screen to be on all the time?
Here´s the app you need!​
Description:
The App adds the posibility to turn off the lcd backlight to your xoom. Its nothing less then a shutdown-button for your display backlight.
The app toggles your lcd backlight to zero and back, said doesn´t just overlay your screen with black, like the other apps inside the market.
it turns off your screen light completly , but the screen stays responsible and the devices stays awake.
Use it instead of locking your xoom, if you need your device itself to be active but dont need the display to be on, e.g. while you´re watching videos over hdmi, use your xoom as a vnc server or something like that.

Use this awesome little App with some "starter app" of your choice.
For example, use the Shaking Shortcurt App, register ToggleScreenXoom.apk and you could turn your screen on/off with just shaking your device.
(tested on xoom [email protected] but should work on every rooted xoom)

DUDE. That's what I've been searching for, don't know how I didn't find it, trying this tonight! Will update back with my results...
Update: Perfect solution. Works great, thanks!

App attached to first post!

does it work on xoom2?
Hello!
Fanstastic app.
Does it work on xoom2? with 3.2.2 rooted?

I used the old method that this thread started as, using market apps. Unfortunately it doesn't work with the Cornerstone version of the Eos roms. What exactly is app? Can you provide more detail? I don't just download apps to try them without some type of info...

I use the current method on cornerstone #16.

"Basically" the same as the old method, right. Just in one app without the need of configuration and with more flexibility to be launched by other apps.
Maybe you´ll try "Shaking Shortcurt". A nice app that lets you launch two other apps by shaking your xoom.

Yeah, think I'll try that instead of SwipePad. Since Swipepad rely's on the borders of the screen and Cornerstone alters the borders, I'm guessing that's the issue. Maybe the Shaking app won't have that issue.
Thanks again for the clarification, and the thread. I really can't believe this thread hasn't blown up!

Please excuse my ignorance but, how would I go about installing this??

i dont understand your question.
just install the app and execute to turn off your screen and again (remember the position) to turn it back on.
or use a starter app like "Shaking Shortcut" to toggle the screen on and off by shaking your xoom.

NO!!! don't flash in recovery, i say that, mainly cause I don't know what it will do... you can install the app while ics is running, I think I used astro but can't remember. What you just asked was the same thing I had wondered.

You´re right. Thanks for the correction.
First post is edited to get it straight.

Does this only work on the xoom? I have an acer 510 and I want something like this. It sounds like this gets launched in conjunction with whatever app you launch. I'd rather that while on hdmi the tablet display is off entirely. Or maybe this does that as well.
So is this specific to the xoom?

According to the readme provided in the zip file this application seems to be specific for the Xoom, or at least a few tegra 2 tablets.

That's disappointing. Why would manufacturer's assume that a user wants the display to stay on while using hdmi?! How about a sane default like leave hdmi output on and turn off tablet display after the normal inactivity duration. But allow a keyboard/mouse not to be recognized as tablet activity.
Could this be modified to work with more devices? Or say newer tegra 3 devices if it's chipset specific. But really, ics should have some application layer to control things like hdmi res, screen active etc...

Nice! Works in AOKP
First of all, this is a great app, and it works well in AOKP (build 37).
To trigger the app, I set my "home" softkey on my xoom (in Rom Control) to trigger the app when the key is held. Even though you can't see the softkeys when on hdmi, after a while, its exact location is easy to recall.
It is really convenient. Thanks for the much needed addition to a great device.

Stop camera from starting on boot?

Anyone know if the Camera app can be prevented from starting on boot? (Perhaps a little contrary to the spirit of the camera, but I use it more for development than for taking pictures, and I don't like the lens motor wasting its time and wearing out its parts). Does it use the "normal" autostart mechanisms that might be disabled by something like Gemini App Manager, or is the camera start up built specially into the guts of the android version on this thing?

Don't know about the details, but enabling the screen lock (swipe to unlock) in settings stops the camera from starting when waking the device with the power button (doesn't stop the start after boot though).

Well, it stops the lens cranking out immediately on power up, but as soon as you do swipe the screen, you are in the camera app and the lens pops out. I'm looking to avoid the camera app completely. I guess if I get up the nerve to root this thing, I can try out an app manager and see if I can disable it on boot, but I'd hate to do unnatural things to the camera and then find out it didn't do any good .

If you are on the home screen when you switch off it will not open into the Camera app.

That depnds on how "off" is is. Once the suspend or hibernate or whatever it is expires and it goes "fully" off, it always starts in the camera.

Are you sure you really turned it off when it went to your homescreen without starting the camera app?
When starting from fast-startup or on a clean boot it will always start the camera app.
The only time it doesn't is if you had it in standby.

A work around is to use this app.
https://play.google.com/store/apps/details?id=de.j4velin.notificationToggle
Use it to set links to your favorite applications.
When you boot to the lock screen pull down the notification bar, select the app you want, then swipe to unlock and it will open in the app you selected.
Of course it would be much easier if Samsung had simply enabled lock screen shortcuts

It would be really nice to disable the camera on boot. It would also be nice to get rid of this stupid mesage:
"SD card inserted. Change storage location to SD card?"
I thought there was a thread for that, but can't find it now.

I only started to get this message since the new update, it appears as though the SD card doesn't get initiated before the camera app loads and in turn thinks you've inserted a new card, when it finally does get loaded. Either they need to put a delay in place or somehow not load the camera app until it's established whether there is a card installed or not.

Disable the BOOT_COMPLETE permission in the camera app but make sure something else has it or you boot to a blank screen.

how can we disable a permission ?
is there a simple app for that ?
Thanks.

The developer of Capacitive Button Brightness recently made a version of his app that turns the capacitive buttons on with the screen, regardless of lighting. Idk if he implemented those changes in the Play Store version, but I'm linking his post below.

Turned out using SuperSU rather than superuser seemed to fix the problem. Getting back on topic I suppose, this version of the brightness app solves the issue of the capacitive buttons! They now illuminate when the screen is on, turn off when the screen is off! you're a lifesaver.

Tips for coping with an un-rooted device

There are a lot of threads here and in the VZW forum about how terrible this device is, etc, without root. I'm a former flash-a-holic and my last several devices have all been Samsung on stock, albeit rooted, firmware. those of us preferring touchwiz have our reasons, and those who prefer aosp have theirs, but this isn't a "why we can't have aosp" thread, this is about making lemonade with what we have.
so, my reasons for wanting root, and how I worked around them:
1. ad blocking. I LOVE adaway, its seriously the first app I'd install on a new device after rooting. without root, give adblock plus a try. you can turn off the status bar notifications in the app and by ticking the box in the app manager.
its simple enough to disable apps on WiFi, just input the proxy host name and port and you're done. I hadn't ever found a clear and concise instruction on how to do this with mobile data, so here it is- create a NEW APN and copy all of the info from the stock APN, and add the proxy host name and port. done, you now have ad blocking on WiFi and mobile data, without root, and without persistent notifications.
2. de-bloating. first, the s5 has less bloat than the s3 or s4, but its still there. it is INCREADIBLY easy to disable or uninstall on this device. go to the app drawer and press the settings icon (or long press the app switcher button) and select uninstall/disable apps. if its ATT or Samsung, and you don't want it, odds are you can either uninstall or disable it. just make sure that in Samsung Apps you disable automatic updates over WiFi. you can also hide them.
myth busting time: IF you were rooted, and IF you manually removed bloat apps, you do NOT gain ANY additional usable space in device storage.
3. tether bypass. there are multiple threads here on how to do this. I have a 10gb plan so its a non issue here.
4. Writing to extSDcard. most built in apps like the browser, email, and camera will save to the ext SD card. so will my files, which is actually a LOT better than on the s3 or s4.
5. removing bloat bookmarks from the stock browser. I prefer the stock browser over chrome, call me crazy. I also don't like the 4 pre-loaded bookmarks being in my list. I saw a tip here to just create a folder called My Bookmarks or whatever you like and put your bookmarks there. the bloat is still there but its not staring you in the face.
so what else have you guys been doing to get functionality that was easy and convenient with root, but still attainable without?

Speed- I find that a lot of people nag about speed, my phone is fluid in all ways. Three factors play into this, using the TW launcher, animation speed, one last tricky one-- S-Voice has a delay on the home button waiting for the possible hook in for user prompting it. My standpoint is you can get from a TW rom the kind of speed or more that you can with a rom somebody else pre-tweaked for you.
Remedies below.
1. Get Nova Launcher (you can look into others if you like, if you want an experienced users perspective on speed, use Nova it flies)
2. Enable Developer Options(click About Device, click build number until it says Dev mode is enabled), Turn OFF animations for Transition window animation scale, transition animation scale and animator duration scale.
3. Open up S Voice (through the double-tap shortcut or in the app drawer). Tap the menu button in the top right corner (three dots) and find the "Open via home key" option under "Wake-up." Disable for slightly faster home button response.
Some people may find this abrupt transition between applications off putting at first but once you give it an hour the phone is flying so fast I could never go back. Enjoy!

As mentioned above:
Nova Launcher
Transitions at .5 or OFF
De-bloating (see this thread)
And - tasker, tasker, tasker!

My tip.. simple but I'm a customize nerd.
iFont available for free from the Play store allows you to add hundreds of fonts to your phone right from the app, and is compatible with the font selection from settings - display.You can also load fonts from the internet or your computer and use that as your default font.
The one lag, I still can't stand... despite all the animations being off is the lag between camera and gallery... like I take a photo, click the little image to view it and it sits there for at least 15 seconds before the gallery opens up. Anyone else have this issue?? I'm so used to CM based roms and still try to swipe to view the gallery LOL

This could be due to your SD card. If you are saving pics to external SD and your card is a lower class it will read and write data in a longer time frame. If you are using internal memory and not the SD card slot then I'm not sure. Backup everything and try a factory reset. I personally don't have an SD card, I don't see the need without root. Also it takes about 3 seconds for me to do what takes you 15. That's why I think an SD might be the Culprit here

There is 1 thing you can not do without root that is needed for me. I own a Pioneer Appradio and use ARUnchained which requires root. If you don't know what it is then look it up. It basically mirrors your phone and lets you use touch on Pioneers Appradio. I used this with my GS3 and if I would have known we wouldn't have root after this long I would have kept it and not bought the GS5. There is no getting around root for this. Pioneer's stock app has restrictions and doesn't let you mirror everything where as ARUnchained solves this problem.

I would like to find a way to save stuff from Dropbox to the external memory.

The menu button function is still there ... just long-press the recent apps button. If you've got a specific app that doesn't display the 3-dots menu somewhere on the screen, you might want to reach out to the developer. That's part of modern Android UX standards. I recently reached out to Untappd and they updated their app to include it pretty quickly.

Ah, gotcha. Unfortunately, short of root reassigning buttons, I don't think that's a desire that will see much traction in the future now that the UX standards require on-screen menus and more devices are coming out without any soft buttons at all. When you get down to it though, you're either tapping the bottom-left of your device or you're tapping the three dots on the screen.

Awesome app called quick click,let's you map your volume buttons for flashlight and a lot of others actions,just throwing it out there missed using xposed,mods with that.

Unfortunately Huawei removed it. Coming from LG G3 it took some time to get used to it. But the placement of the fingerprint sensor is very good indeed. I do prefer the back of the phone to the front.

If you have root try this:

I've checked the files though (you can read them without root, but not modify) and all the entries are there, so it's supported just not enabled. Seems Huawei disables DT2W by default on devices with fingerprint scanners even though support is there. Makes no sense to me, but it is what it is.

dt2w setting appears but after enabling it does not work.

This is bad news but I'm pretty sure there must be a way to enable it somehow Since support is clearly there.

There must a be reason why Huawei is disabling DT2W feature..

Probably DTW has been disabled in all their new smartphones with a fingerprint sensor (ex. Mate 8): is it not compatible with lock/unlock security?
AFAIK the Honor 6 Plus which has recently been updated to Android 6 keeps the DTW function, so apparently it's not related to Marshmallow.

The finger print sensor is actually fast and good.
And it is actually placed beautifully. Easy to use

True, but when the device is placed on a table and you want to check time there is only the power button.
In 80% of cases the FP sensor is fine. For the other 20% it would be nice to have the option.

Hai dear friend if you are ready to use third party apps then we can have a solution.
Try this app it just works fine in unlocking the screen by double tap.

On my H7 with B330 Digirom 4.2 I have dt2w.
Go to Settings -> Smart assistance -> Motion Control -> Double touch (at the bottom)
Edit: Sry guys, not sure how I came upon the P9 forum, thought I was in H7

This kind of apps not need a rooted device or something?

Missing dt2w is the only flaw of this phone... Really hope they do something about it with nougat.

If fingerprint is enabled then dt2w is irrelevant anyway

Kinda. In most cases it's fine. It would still be nice to have the option. You know when the phone is laying flat on the table and you want to check time or notifications...

Hello,
I found onthe Google play store the app "Always On" from developper DUFRELLER, and it works very well on my Huawei P 9.

If your screen is always on, your Huawei P9's battery will die really, really fast. You don't want your screen to be always on because it is a non-IPS display panel.

i told you guys use application like wave to unlock and lock

How to turn on double tap feature in this phone

I played with a P9 on display in a store last week, it did have double tap to wake.
