can you turn the screen on without pushing power button?

title says it all; its a PITA to reach around through the case to turn the screen on all the time, and, even though the screen is supposed to come on when you push the menu key on the hardware keyboard, it doesnt work that way, at least for me..
Can anyone offer any other suggestions?
I know once I root this, there will be other choices, but, I want to learn more about the device before I root it
thanks so much for your help!

no, since xoom doesnt have soft keys so the only way to turn the screen on its to touch the power button. in other terms if you want to wake the xoom up when screen is off you need to press power button.

hopefully, some one will develop a software fix
for this; I cant be the only person that is annoyed by this..
thanks!

What's so hard about pressing the power button?

if you have the motorola folio case on it, its a pain reaching through the cut out every few minutes to turn the screen on..

Idk if it works on the xoom but simply lockscreen on the market has a feature that uses the devices proximity sensor to unlock the phone, it might be just what you are looking for. Like I said, not sure about compatibility but the developer is pretty active here on xda and he might be able to figure something out.

The Xoom does not have a proximity sensor. One developer that frequents the forms and gave us all a screenshot app for the Xoom for free, has an App Killswitch which does the opposite action that you want. When you close the case, the light sensor senses the darkness and turns the screen off. It would take more battery but likewise would be possible to do it the way you wish when opening the cover. Maybe if we ask nicely, he can make it happen

well, I installed nolock, from the market, and it reduces the steps to one to get the screen on; when you push the power button, there is no lock screen to go through, which helps, but I wish there was a way to wake it up with either the keyboard, or just tapping the screen..
I'm sure this will come one of these days..
EDIT: It only works sometimes, not ready for 3.0 I guess....

It is possible but will not work until we have a deodexed ROM. The is a way to remap the volume keys to wake the screen but as soon as the keyguard kicks in the volume keys are disabled. With a deodexed ROM I can disable keyguard. An alterative option I might be able to work out is to wake the screen with a paired keyboard via blurtooth. So far in my testing this is working well.
Basically I have mapped the F1 key on my keyboard to wake/sleep the Xoom.

that would be fantastic!
I bought the moto keyboard, hoping those features might be baked into it, but they arent.
I could have saved 70 bucks, and just used my apple mini BT keyboard...
Keep us informed, and if you need a tester, I will be glad to help out!

Try to push the below file using adb ... you need root for this to work. After rebooting the right ctrl key on the Motorola keyboard should become a power button for you. Let the screen goto sleep for a few minutes and attempt to wake it using the button. Let me know if this works.
Download:

ADB PUSH:
adb remount
adb push Vendor_22b8_Product_093d.kl \system\usr\keylayout\Vendor_22b8_Product_093d.kl
adb reboot
Make sure you unplug the USB cable before testing. I think while it is plugged into USB keyguard is disabled.

I appreciate it man, but I haven't rooted the xoom yet..
I want to wait a bit, and learn it better before I do.
Even when I got my evo last june, I waited a few weeks b4 rooting to learn it beter.
thank you for the file!

This has been discussed many times on this forum.
Long story short, I agree with you, especially since I leave the xoom on a table during a meeting. My solution...I downloaded Widgetsoid2.x. Among other widgets, I have a no turn-off widget on my main page. walking into a meeting, i hit it, forcing the xoom to stay on. obviously kills the battery, but i still get two full days.
not pretty, but it works.

I personally don't like the power button placement myself. It's all personal preference. But that's the benefit of getting and Android platform right? If something doesn't quite fit our preference we can personalize it. I think that's all the OP is asking for.

Ditto. The case I bought till a nice option comes along doesn't have the hole for the power button. That's why I started looking for alternative options.

Posted the how-to in the dev section for Moto/Apple/Generic Bluetooth keyboards for those interested.

What is that you are doing that it is going to sleep? The easiest thing would be not to let it sleep so quick. Set the timeout to 15 minutes or something.

I guess I am still treating this like my EVO, which, doesnt get the best battery life if you leave it on too long..this thing gets awesum battery life, so I think I wll start leaving the screen on longer, until someone comes up with software that will wake it up easily..

Slide to wake or touch to wake?

Anybody have insight if this is possible on n4? Would be a downgrade if not possible. I am surprised touch to wake isn't on every phone by now. Bb10 phones are rumored to have it.

I know what you're talking about, I have it on my sensation but it uses capacitive buttons to work and the nexus 4 uses on screen ones. I don't know if you could get out working without a hw mod

I'm sure there are apps out there that do this. The biggest problem with what you want is that the screen/digitizer has to be active to achieve it. With the current unlock system Android, Apple, and Windows Phones have they save battery by making sure the screen is off. Can you imagine the phone always registering every touch? In my opinion it would be a downgrade to have that feature. But if you really want it then maybe look into this. http://lifehacker.com/5921321/smart...lay-on-or-off-when-you-wave-your-hand-over-it

Not interested in an app like that. Tried it a long time ago and it is terrible in real world use. Pgm nexus works awesome. Haven't seen any noticeable hit in battery life since Ive been using it. There are a few kernel I believe that you can use touch to wake, but nothing to my knowledge that has slide to wake/unlock. I rarely ever use my power button. So then lucky beneficiary of my phone soon will get a pristine nexus. USB ports hardly used also because of car and pogo dock and wireless data transfers.

Double Tap Lock & Wake Feature

Does anyone has any idea regarding how the double tap to lock and wake works?
Need a port to other devices

I highly doubt it works on rom or device other than the g2 stock rom at this point.
Maybe scrosler knows.

I believe it is part of the launcher.... I thought I read some where that if you installed 3rd party launcher you lost that function...

Or download "Lock Screen" from the play store and make a double tap gesture with nova launcher that opens the activity of that app. That's what I did and I have the double tap to lock working. The unlock works regardless of launcher.

I attempted to write an app to do this a long time ago. If its app-based like that, it needs to keep at least a partial wakelock on the phone to "listen" for the knock knock.
My guess is, on a multi-core CPU like the G2 has, they are turning off all but one core and putting that one core in the lowest MHz it will run, just to "listen" for the knock knock. Not app-based, but kernel based (like PGM). Clearly this doesnt use very much battery at all, as judged by the stellar battery life people have been reporting and that Ive seen on my own G2.

hi
I thought it worked off a motion sensor.. unlike the HTC One kernels and franciscofranco's mako kernel, which use the touchscreen. I can't remember where I read it but I think it uses motion sensors for this, gyro or something
I don';t think it uses the main CPU cores, it uses another ultra low power one to work. This is why these features drain so much on the One, because it doesn't have the extra things that the G2 and MotoX have
no idea what I am doing in this forum but I thought I'd answer it
Edit:
The software platform is Android 4.2.2, and atop that is LG’s skin. LG has added a bunch of new features to its skinned Android experience, although its visual themeing remains essentially unchanged. Double tap to turn on and off uses the built in accelerometer to wake the phone up or turn it off – you just double tap quickly on the device when it’s in an off state to turn it on, and double tap quickly on a blank part of the display or status bar to turn it off. I don’t have a problem getting my index finger to the raised power button, but this is obviously an accommodation just in case that’s difficult.

I lose about 1% battery every 3-4 hours when idle the whole time so while it may consume more battery the amount lost doesn't matter to me since idle drain is still hardly anything.

With the screen off and in the right light I can see hundreds of small grid like squares. I always assumed that they had something to do with the knock on feature.

I'm pretty sure it's NOT the accelerometer.
I tried it, and it even works with the slightest touch I can do. I hardly touched it at all. Can't believe, that there was any motion.
Furthermore it doesn't work when knocking with my fingernail or any other thing.
So I think, it really works by touch-recognition by the display.

you are right. it's definitely the touch screen waiting for the touches.
just try it on the edges on the screen - still works. next to the edges - doesn't work.

There's this post that I read somewhere from HardwareZone:
Not too sure if this is a solution, my imagination or simply I have gotten perfect overnight on using the KnockON feature but the insensitivity issue, that many and myself, have been facing is now gone - since last night, after I performed the following tests on my G2. (Yes, thses are merely TESTS, so wasn't expecting much..)
I got my set on the 26/9/13 and until last night this function got rather spot-on accurate and is not behaving in that erratic manner any more - at least for me. Here are the steps :
First Test
- Key in 3845#*802# on your phone dial.
- HW Device Test > Touch Test > Multi Touch Test
At this point, drag your finger across the screen from corner-to-corner and when your done. Press Volume-Up key once to exit.
Second Test
- From the same menu select "Touch Sensing Test 7*12"
- Tap in every box as many times as you want and on the red text as well at the bottom of the screen.
- Press Volume-Up Once to see result
- Press Volume-up again to Exit
- Finally, to exit the whole menu just use "return" soft key.
Once again, I like to highlight as strange as it may sound the above method has worked for me. And if not, then something definitely has. Do take note, Rockwell screen protector is still on and lastly, please do share your findings.

I tried it and strangely this seems to work. I can't tell if it's placebo but now I'm a hell lot more confident that my phone will wake up at the first pair of knocks.
Also, this is definitely true for me:
The knock on is 100% effective the first try when my phone is lying flat on my desk OR vertical on a car mount. In fact, these are the only 2 instances where I actually use KnockON. When I hold my phone, I naturally use the power button. Yes, I still do have probs with knockON when I use my thumb to wake it up while holding the phone.

3845#*802# did nothing for me. No menu.

There are apk for the knock on feature. But I'm sure there are libs and services involved

Could be the motion sensor. Try doing the double tap while holding the phone in your hand... It become completely unreliable. BUT, it's 100% reliable for me while the phone is laying on a flat surface.

Nice! Love this feature. Always envious of lg for that. How much does it effect battery life

noticed the nexus 9 has it too on a video i saw.

Maybe that's a typo or he got confused with the 9? Strange that nobody else mentioned what would be a pretty big feature...

I hopefully does it, because after getting use to it on my g3, i catch me some times trying to wake my other devices with double tap

I loved that feature on my G2, M8, and now G3...but with my G3 always turning on in my pocket I was ready to be over that feature.

I'm not a fan of bringing back dead posts but double tap to wake does not work on the nexus 6, or at least not on mine.

I'm still hoping they included it, just not yet enabled. Or maybe a dev can activate it, especially since it is on the Nexus 9. Key will be if the digitizer and screen are on different power planes so as not to drain battery.

I hope a Dev can enable it with a new kernel I miss that from my G3

Its only worth enabling if it doesn't completely drain the battery IMO ... and that depends on hardware .. thats the reason why Nexus 5 couldnt really use it ( even after activated by the devs ) because the hardware wasn't right :
It had to keep power to the entire screen rather than just the digitiser, thats why the G3 etc don't drain the battery .. lets hope the Nexus 6 screen is built to supply different power to the digitiser and actual screen

Fingerprint - Unlocking from Always On Screen

Does the fingerprint unlock require that you press the home button? From my understanding, you only needed to place your finger on the home button for it to unlock.

Always on acts as the screen was off, so yes, you have to press the home button first, but you can just leave it on the button after pressing and it will unlock straight away.

Or, you can activate the edge screen by swiping at the edge, when the edge screen comes up (AOD would disappear) , place your finger on the scanner, and the screen would unlock

I really hope samsung brings an update to just unlock the phone by placing the finger on the home button. No pressing and all. It feels so much better like that on iphone and nexus.

Well, if a hardware component is designed to be always-on, it will not drain the battery. For example, the edge swipe will not drain the battery although it keeps the touch controller on. On the LG G5 and Nexus 6P the fingerprint sensor is always-on and does not drain the battery.
However, if Samsung did not design their sensor to be always-on, then there is not much that can be done via a software update.

Well, how about a simple setting to switch between the two modes. If the hardware is designed for always-on, it can surely work when pressing the home button first.

2. Even if bull**** did arise (which it wouldn't) they could just move it to developer options. That **** on there is basically all useless anyways.
And 3. It's not "adding options and toggles all over the place". It's 1. Signle. Toggle. Honestly I couldn't care if they had a toggle for that or not but it just pissed me off that you were so keen on shutting this idea down and op didn't even respond to you. Dickhole.

First, name calling is childish, and often a sign of low intelligence. That might not be true of you, but that is how it comes across in writing.
To comment on your points:
1. Most people on XDA, yes, which is a super small minority of all users. It has been shown many times that average consumers (the overall majority by almost 10:1) want products simpler.
2. I agree that a good way to handle additional options would be to shove them in a separate developer or advanced settings area.
3. Noted. That's your opinion, and you're entitled to it. Just don't assume your opinion matches what the majority of the overall population want.
Sent from my SM-G955U using Tapatalk

That's not an opinion. That's a fact. It's 1 toggle. Just one. It's not like they're opening another section in the settings. Just one toggle. And if they want simpler phones they can go to iPhone. That's what iPhone is for. The technologically uninclined. OP is just talking about one single toggle that will let you choose between one option or another. It's not even that hard to code in. I highly doubt that not almost everyone wants more settings. More settings is great! You can make your phone your phone! You can have it do exactly what you want. Whether it be consuming extra power for a fingerprint scanner or conserving it. Hell put it in the toggles for powersaving so when they turn power saving on the fingerprint turns off until it's clicked. Literally so many ways you could go about this. You could make it so the scanner is on between 8am and 10pm but off at night. You could make it so if the phone hasn't been touched within an hour the scanner turns off. There's no reason not to have extra features. Unless you're super old. Then I think you'd want less features. That's what easy mode is for. (oh and apple is for that too. That's why so many old lady's have iPhones and so many old men have Android's. I would guess at least)
Edit: I also only called you a dickhole because I was pissed that you shot this dude's idea down until he gave up. You were just being a dickhole to him. So that's why I said that.
