[App] Power Switch - turn off your screen by shutting the case!

Hi guys, Im the dev of an app that will allow you to send your Note to sleep when you shut its case. The PR is after the break.
Now that we have three high end tablets with proximity sensors (Note, 7+ and 7.7) its time we did some testing to see what sensitivities we should set in the app by default.
Please help us out with this. Simply download the free app, mess around with proximity settings until they work and report back what lever (in %) you needed.
Note that the current auto-selection prompt will only enable the light sensor if you pick "Tablet" in the first run dialog. You will need to turn the proximity detection on manually in the app's settings, as your tablets actually have this sensor!
Thanks in advance, and i hope you like the app
--------------------------------
Power Switch:
Power Switch is a tool for devices with cases - somewhat like the SmartCover, it will turn off the screen when you shut the case. If you have a device with poor
battery life, Power Switch can save tons of juice by switching it off entirely after a given amount of time asleep.
The app works best on phones using the proximity sensor. On tablets, the light sensor is the most efficient method of knowing that the case has been closed.
Features:
- Sleep seconds after shutting case
- Automatic shutdown (rooted devices only)
- Set up a schedule using Night Mode
- Configure sensor sensitivity
- Facedown to turn screen off
- Persistent notification
- Plays sound to let you know that the screen has turned off
The app has gone through an extensive testing process here at XDA under another name. Thanks to everyone who helped make it happen, you're the best!
Remember to adjust the light sensor sensitivity settings in a light environment for best performance, and use Night Mode if you are on a tablet with a poor ambient light sensor.
If you have any comments or suggestions, please use this thread or the in-app feedback tool. Please be aware that we ignore logs without descriptions.

The Lite version of the app is exactly the same as the Pro, only the timers are restricted to a minimum of twelve seconds.

What the hell is deep sleep friendly?
It works like pressing the power button, except it uses the sensors.
Now, please, lets get back on topic, read the OP!

He means does the app stop the phone from going into deep sleep, therefore using more battery. I've been using it for a few days and i think that it does affect the deep sleep as mine is at 200mhz most of the time now.
I think that the app works well with the original flip cover and the audible notice is a nice touch
Sent from my GT-N7000 using xda premium

No, in android sleep is sleep. All apps will shut down unless they have a push service. The sensors will also shut down.
Basically all the app does is press the power button for you, nothing else.

I'll have to investigate and see what's keeping it awake then

Read your thread.Your findings are absolutely correct.
I have posted same issue somewhere else. But when i have used both sensor Proximity + Light, it was worked for Me.

battery hog?
I am using it, and it seems to work OK apart from some false positives when browsing in landscape. The 'go away until next screen off' is a good option!
I am finding it is taking quite a significant %age of battery, however. Not killing the phone, but 5% when my screen is only at 18% (a light-use day).
Anything that is going to hog 5% of my precious battery is going to be looking nervously at the door. I'll try it some different use scenarios, but I think I'll just settle for the 1 min time-out. Really, if I am not doing anything with my Note for a minute, I've either fallen asleep or put it down!

1.1.4
Added option to disable in landscape
Fixed issue with switching Night mode
Fixed many device specific bugs (Tab 7.7, 8.9, 10.1)

hope it allows deep sleep for android

Yes, this does not affect sleep at all - it only puts to sleep, not wakes.

Hi.
No, there is no such function on the TF700.
The 7" Nexus tablet has it, but not this one.

For the Galaxy Note with a Flip Cover, we can to use the sensor of light and/or sensor of proximity to obtain the same result of Smartcover.
You must install the app Power Switch and it's work.
I think or i hope it's okay with our TF700 ... what do you think about this ?

i actually think thats a really good alternative...gonna look into the lite version when i get home...

This app is VERY impressive, thanks for the suggestion. My friends' jaws dropped when they saw it in action. Silly iOS users. :laugh:

Need some help
I installed Awesome on off ultimate on my Transformer Infinity, but have some problems. The only way to turn screen off is to press the Screen off icon. No gestures or flings will turn it off. Tilting the Tab turns it on ok.
When I pick ut the Infinity to bring it with me in a bag, the screen turns on by accident, draining the battery
What can I do to turn the screen off with gestures, including those needed to turn off the screen more permanently so that I have to turn it on with the physical on/off button?
Thanks

Incorrect.
There IS a magnet sensor on the tablet to turn the screen off when the dock is close to the screen. The magnet is on the right side of the keyboard dock, sort of beside the touchpad and under the menu key.
Problem is that sensor only gets activated when the dock is connected. Maybe there is a way to trick the tablet to think the dock is connected and enable this sensor. Sure would be handy to have a magnetic screen off switch on sleeves.

Could I ask how do you know this? Is there a way to check the presence and state of such extra sensor. In the kernel source there should be something.

I'll be able to confirm if the dock has a magnetic sensor in a few days. I have a magnetic stylus that I just got a few days ago that should be able to trigger the sensor if it's there.
What I can say already is that there is definitely a magnetic spot in the location described, to the right of the trackpad and below the menu key. My stylus holds on very well there. I had the tablet on the entire time though, so no chance of accidentally seeing any sensor behavior. Would check now, but I'm away from home for a few days and I forgot to bring the stylus with me.

To test it, it's simple. Put a magnet on the screen at the position corresponding, on the dock, to the one described by pileot and you ll see that the screen will switch off.
As pileot said, unfortunately, it only works when tablet is docked.

I have Apex Launcher installed.

Also, do you have set for the display to go to sleep? I noticed if I carry my tablet in portrait mode, the screen doesn't turn on. Maybe you can give that a try. Hope that helps.

I'm not understanding how to turn the screen off with ultimate on. What icon do I press. I press the one in the notification bar and it takes me to the ultimate on menu. It doesn't shut the screen off.

Just sent grandmaster an email if he can make a setting for us without a proximity sensor. Use with tablets. We should be able to set the tablet down for a couple of seconds and the screen should shut off. Maybe even give us a choice on how many seconds before the screen shuts off. I would like 3 second delay the off.

Several things. First, i have taken the dock apart (to ad pennies into the front of it to make it heavier so it tips over less) and noticed the magnet. Second because if you take a paperclip or other light, metal object and place it about 1 inch to the right of the touchpad and about 1 inch below the keyboard it will stick. Third, when the tablet is DOCKED you can put a magnet at the right spot in the screen and the screen will turn off.
Problem is it only works when docked.

,has anyone tried to use a magnet to sleep the infinty with the transsleeve locked in instead of the dock? Wonder if it just has to have something in the slots for the magnet to work.

Don't know if someone is interested in this, but due to this thread I was able to locate the hall sensor position of my TF701T. Obviously it is the same as of the TF700T. Without anything docked I am able to put the TF701T to wake and sleep with a little magnet.

Not sure if anyone is still following this thread but there is a solution for Eroc162 turning off the screen with a jester. It's called Screen off and lock. If you have the swipe to search button and don't use it this app will use that jester to turn off the screen. If you are like me and have flashed KatKiss KatshMallow 6.0 (Marshmallow based ROM) you can use the onscreen widget . Works great!

Flip case - screen off - Any sucess ?

One missing feature of our beloved note it the ability to turn the screen off when closing the cover over the screen.
Also proximity sensor is missing too..
However there are apps that make use of the light sensor to turn off the screen...
I have tested various apps including tasker, locale plugin, smart screen off and so on, which can make use of the light sensor to turn the screen off..
But I find that the light sensor itself is not very sensitive in low light conditions..
Even in a dimly lit room the sensor detects only 0 lux and forces the screen off... Bummer..
Anyone here sucessfully using case close screen off ???????

Ipad and few other devices like nexus 7 makes use of the magnet sensor.. THis is the best way to do it as there is no battery consumption.
Samsung may not have included this as the magnet might interfere with the s pen..

Screen turns off while using Papyrus

So I am studying and taking notes on papyrus when all of a sudden screen goes black.
And it's not like it went to sleep mode because if I hit the power button it makes a sound but does not turn the screen back on.
When I click the second time it turns the screen on, as if I turned the screen off and on while it was black screen.
Has anyone experienced this?
So far I have had this only happen while taking notes on Papyrus, I have 30min set to turn of screen and this happens during my note taking...
Also I am using GMOD SPen, to turns of capacitive sensor. -Maybe it could be the problem?

The only input I can provide is that under the same circumstances as you, ( GMD to turn off capacitive touch) and using papyrus, I had no such issues.
Something I feel I should share though, is that the spen latency is greatly decreased in papyrus on a custom ROM such as baked#8 but you lose the Samsung features.
Just my 0.02
Regards
Jack

What about Android Revolution HD 5.1?
I was having serious latency problems earlier but that was due to 2d gpu acceleration.
Once I disabled that I still see some lag, but it's much more tolerable.
Should I try the rom you mentioned, is the latency really that good?
So far, the least latency I've seen was with software called "write" although it has a lot of useful features Papyrus is still my favorite.

Well, if you are comfortable with taking a cwm/twrp backup the you can try it for yourself
I noticed a great deal of difference personally.

I've actually had the exact same issue, although I use LectureNotes: I can be taking notes from anywhere between 2 minutes and 30 when the screen suddenly goes dark (but not off). Pressing the power button turns the screen off and another power button press brings you back to you note-taking app.
I thought this was an issue with LectureNotes' auto-saving feature, but after seeing this thread, I'm thinking it's system-related (software or hardware).
Anyone have any insights into why the screen randomly goes dark while using the S-pen?

Bad Proximity Sensor?

Is anyone else having an issues when on a call to someone you take it away from your ear and look at your phone and the screen doesn't come back on. I have to hit the power button to make the screen wake up. I'm all stock (4.4.2) with unlocked bootloader. I m trying to see if this is a hardware problem where I need to RMA or software problem.

Mine works perfectly well. Are you sure you don't have anything that might be affecting the proximity sensor, like smudges or a screen protector?

No, I don't have any screen protector not any smudges. I saw similar issues on other phones and someone said to clear data and cache on the phone app so I don't know if that will work or not.

What time out do you have your screen set to? Sounds like it's simply locking after the designated time.
I've noticed the screen turning on and off occasionally when talking. Almost like the sensor isn't sure if I'm holding it to my head or not but then I do hold it away from my face.

I have the same issue...
I can't hang a call because the screen simply don't turn on when I remove my phone from the ear.
In add at this issue, seems like the proximity sensor turn off the backlight screen only.
When I finish a call, I found the clock screen opened, in my case the settings screen of advanced clock widget...
It's really annoying...

Do you guys have a screen protector applied by any chance? Everyone had this issue with the nexus 4 because the sensor is really sensitive and picks the protector up, not letting it turn the screen on. Try removing a section of the protector where the sensor sits, this will fix your issue.

Surprisingly, I don't have this problem
Team Nexus 5 sucks. Underpowered battery for a 5inch 1080p screen that is non-removable. Weak generic antenna that drops signal. Worst speaker of any device on the market. Cheap plastic build.

I have it on 15 seconds. Shouldn't that feature be bypassed when a call is in progress so that the proximity sensor is usable. This is the first phone that I've had that has done this to me. On all others the proximity sensor stays live even after the predetermined sleep time.

After 15 seconds you're screen is simply turning off as you have set. Mine does so after 1 minute, which is my screen time out setting.
