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...

nope its in the kernel, the launcher just allows you to do it anywhere on the homescreen if you are on a 3rd party launcher you just have to tap the status bar

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.

Yup, I'm using the nova launcher, double tap status bar still working
Anyone has any idea how does it work? Is it the digitizer just stay awake and listen for unlock? Won't it consume a lot of battery?

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.

Haven't looked into any code but Brian is knowlegable when it comes to these things
Could be the reason why, *according to reviews* it doesn't work 100% of the time

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.

You know pretty much every super LCD screen has them, it's just to what degree they show

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.

Kitkat impressions?

Hi VZ Moto X folks,
How are you liking Kitkat on the phone? I installed the update on my VZ Moto X this noon and do like the update overall, but I have a few gripes as well.
Likes:
Transparent status bar, white looks good and different as well IMO
New camera allows to adjust focus, exposure (technically this not related to Kitkat I think)
Wallet is working again on VZ with NFC
Lockscreen music album art is very nice! Also works with apps like Pandora and Tunein Radio
New dialer, but no business search
Gripes:
Lost root from 4.2, chances to get it back on 4.4 seem slim. Really hate ads
Some issues with Chrome on 4.4 (lag etc), hopefully will be fixed by an update to Chrome. Chrome never lagged on the Moto X for me on 4.2.
4.4 broke support for battery apps like BetterBatteryStats and Wakelock detector.
Overall, I am really impressed with Motorola and Verizon for giving us this update so soon. But the Moto X was such an awesome phone to start with that I am not totally overawed by the update, I think. What do you guys think about the update?

I'm pretty upset about a really small thing: When I unlock from Active Notifications, there's a tiny delay in which the regular lockscreen appears, and then it unlocks to home/whatever app I had open. That wasn't there before, was it?

I'm happy with the speed of release, but I'm a little disappointed with the crippling of some features. The lack of local search in the dialer and Google Caller ID is very disappointing.
Oh, and this feels like nitpicking. But holy crap:

If you haven't tried yet, switch to ART runtime in the developer options. It speeds up the phone a lot.

Yes, that to me is a actually one of the most important updates because you feel it every time you unlock or every press (if enabled). Much smoother now.
I really don't like the new dialer app. The white/gray looks plain ugly and I don't get what's the obsession with light themes.
Otherwise, I like it all

Yes! The icons are terrible in the status bar. They also used the old Gps icon instead of the new location one.

I like having the option of using art. And will try it for today. But might have to get rid of it until more apps are compatible. Its not horrible but my banking app and PANDORA don't work. The lag is also TERRIBLE when unlocking from active notifications. And disabling slide unlock screen is NOT a fix because the lock screen is how I change my music when listening. Motorola should NOT have skipped the soak test.

Wait... Motorola shouldn't have skipped the soak test because you want to enable an unsupported beta feature that's only accessible by enabling a development settings menu?

Fix unexpected screen sleep!

Are you tired of your Mini/Ultra/Maxx falling asleep at random while using it? Does the phone fall asleep while actively scrolling through your home screens and apps drawer? Well, my mother and I have both had this issue and I found the solution to fix both phones:
INSTALL AND SET ANOTHER LAUNCHER.
And that's it. If you haven't already, use Google Experience Launcher to get some of the KitKat Moto and the Big Red didn't give us!

Yep, the stock launcher watches the proximity sensor (to the left of the earpiece at the top) and if you pass your hand or something a few inches above it will mistake this for putting in a pocket or a bag and will sleep the display. It's a nice feature, actually, unless you regularly pass your hand over that sensor.

I just wanted to put this in the open. The people I know and undoubtedly many others find it annoying, including myself. The screen shuts off on me even in broad daylight.

New OTA Moves features are sweet!!

With phones it is all about those small things that make the experience for you ever more enjoyable. Like everyone else not being able to quickly view notifications while your device was sitting on a desk was kind of annoying. While there were apps that tried to mimic this feature it just quite wasn't there.
Well with the new OTA that I promptly side loaded the Pixel is nearing perfect for me. Coming from the S7 Edge makes it even more enjoyable. Why? Because the S7 Edge always on display was kind of useless. Sure you can see the time and a few notifications but it just did not apply to enough apps which made it more annoying.
Anyone just my 2 cents.

I JUST started using PIE controls by coolace (due to having seen it on this threat). It is working great so far, no slowdown or hangs or anything.

btw my is really slow right ?

i found one funny issue with my pie control, if i open pie control in any screen other than home screen, it work perfectly but in home screen it take few second to load, any one have idea what it cause ?

I am actually taking back my recommendation on this app...
more than once I have had it kind of "take over" my screen.
What I mean is, any touch on my screen is attempting to touch something in PIE control (and not actually graphically showing PIE control, btw).
you effectively can't do anything at that point.
Its been a few days since I stopped using it, but I really did pretty exhaustively try to figure out how to stop this.
I really liked this app's "swipe" method instead of pulling the PIE out and having to like hold on a button for a quick sec, this app lets you do it in a smooth swiping motion.
Anyways, ive given up and gone back to onscreen navigation keys.
Every method I have tried (including XDA's navigation) has had some small hangups that eventually have problems working.
And no I haven't reported errors and such in respective threads, I just give up because my "lots of effort into having a hacky phone" days are behind me
