Hi, thanks for your reply! I tried this Tap Tap App and in my opinion it is not usable. Even you got the red eye monster (proximity sensor still shines).

Little bit better for use, but does not lock the screen as well.

Smart Screen ON
I found really nice app called Smart Screen ON: https://play.google.com/store/apps/details?id=it.android.smartscreenon&hl=en
Paid app.
It works really nice in wave mod and in tap mod on proximity sensor as well. BUT: proximity sensor is shinig for example 5 minutes (minimum) and then app doesnt work!
I think it should be a kernel feature to work without proximity sensor...

No more choices?

lock screen app
I figured it out with app called Lock screen app (https://play.google.com/store/apps/details?id=kennethcheng.com.lockscreen.free).
I have an icon in home screen for turn off the screen and the shortcut on lock screen of this app to turn off the screen after home button is pressed.

You will see when your power button will go wrong... Btw I have hard silicone case on mobile and it is little bit hard to push down power button...

[REQ] Camera hardware wake button

This is a request for any button (trackball would be ideal) to wake the phone, AND launch the camera application. Lets assume it will sleep again after x amount of time, just like normal.
Maybe this could be in cyanogenmod settings ?
Maybe this could be a combination, say TRACKBALLTRACKBALLTRACKBALL or something ?
thank you

I think it will be just as easy as
1. Trackball wake
2. Trackball unlock
3. Press camera shortcut
Just make sure the camera is on the home screen...
Just get Widget Locker. Trackball Wake > Camera.

i'm going to try this now. thanks to both of you. also, would it be possible to keep the phone 'locked' while doing this, so you could have a child/friend use it as a camera, but not have the phone and other applications accesible without entering the unlock pin/pattern ?
thanks again !
Like it! I would love this:
Short press - unlock or screen on
Keep pressed - unlock directly into camera

Different lock screen

Are there any ways to install another lockscreen but not by using apps (making them native, I don't like the way it works in widgetlocker app). I have root, CWM and so on
To be honest I want puzzle lockscreen like it was in Vibrant.
*Ripple lock
it's on the marked and xda .

But unfortunately this is still an app superimposed to the original home screen or lock screen (which sometimes appears...)
Also the notification bar remains visible!
Original lock screen can't be actually replaced, but only hidden.

That's why I dont like those apps.
And why are there tons of lock screen in Vibrant Roms/i9000/Captivate and difficulties with i9100? What is the principal difference?

Besides home button unlocks the screen. Even with enabled and disabled notification bar.

+1 on that!! I hate the lockscreen so much, I'm using AntiLock to disable it. Apps like WidgetLocker or RippleLock are no proper alternatives because they either unlock with the home key, or have 5 seconds limitation, show the Samsung lockscreen underneath and such.
Just like you, I wonder what's taking devs so long to come up with alternatives. Why is it more challenging on this phone than others?
Guys,
I'm using WidgetLocker and enabled the Root Helper option, and also disabled the default Lock Screen. (In Advanced menu) and also checked Disallow WL suspend.
With these setting the defualt screenlock is only displayed for 1-2 sec when I restart the phone. but that's all.
Previously I also encountered the problem that I had to unlock the WL and then the stock one but now only WL is running.
I don't like lock screen in widgetlocker and in gingerbread itself. I like puzzle one or the one from ripple lock, but it doesnt work properly

Tap to unlock in galaxy s2

hi all, as the title tells is there a way to make it possible? a single tap, double tap or as per user choice, or touching specific area in the display to wake the screen.
the display does wakes from sleep mode when receiving mail,calls extra without touching the keys, so can the same mechanism be achieved to unlock the screen?

This thread may be a good start. It's an app that lets you re-map the double tap to launch a certain apk. If you somehow change that to the unlock command or create a very basic app that unlocks once open then it should work.

i think we have to remap the wake event sent by home button or power button to the display unit, lets ask the app dev in your link and see if we can get something fruitful
according to me its a wierd feature..that requires tap to unlock......
always sliding is better nd stylish to use...........
tapping to unlock is a ****ty idea that all nokia symbian based phones exists......
so devs doesnt focussed on this .........
try widget locker or go locker, it provides as many as better nd good screenlocks than u said to make implement by devs.......

Put it this way, how about waking the phone from sleep mode using tap instead of pressing power key or home key. Won't that be useful ?

I think if that's the case (waking the phone by just tapping and not through the power button) buddy then the phone should be awake to recognize the tap causing battery drain and prevents the phone from going to deep sleep. On the other hand unlocking the phone by double tap might just be a good idea

I wonder what happened about this? Would really be useful, no progress eh?
Does anyone know if a rom which has options "tap to wake" or "tap to unlock" as in G2 ?
You need modifications in kernel in order to do this, and I doubt it would be battery efficient enough to make it work on this phone.

Double tap to wake/sleep

Does anybody know a way to enable double tape to wake/sleep?
Instead of double tap, long press on the bottom of the screen where the home button would be if the screen were on. There's no built-in double tap to sleep, but some third party launchers (like Nova) have implemented a work around. But it only works on the home screen.
The home button method is lmag, but still not great. It's nice to be able to just tap any part of the display and for it to wake up. That's one thing the iPhone definitely got right this time around compared to S9+

the rating speaks for itself :crying:
Implementing this feature will probably add battery drain as some sensors need to be active all the time also a custom kernel could implement it. Wait and see

It can be an option.
The S9's "always on" home button requires a sensor to be on all the time, too. But the SD 845 has a very low power mode to support these sorts of things. I don't think double tap to wake would use any more power than Samsung's approach. But I'm happy with Samsung's approach, but I wouldn't mind a double tap to sleep, like my old G3 had.
ElementalX has double-tap to wake.

Well, sort of. One, it doesn't really put the phone to sleep instantly. What it does is reset the screen timeout to a very short value, so the screen goes black. Then, after the phone really goes to sleep, it resets the screen timeout in the background. Two, you can only do it from a Nova home screen. In LG's implementation, you could tap on the status bar on any screen to put the phone to sleep. (Or maybe it was the Nav bar. It's been a long time since I had my G3.)

Yeah you are correct on both. LGs way is anywhere half way down the lock screen could be double tapped to go to sleep. That's what I'm looking for. Just grabbed the s9 and I miss the dttS on the ls. The double tap on home button isn't too bad I suppose but still also miss the full screen dttW from LG.
if you have the home button showing on always on display you can double tap it to wake(instead of pressing it hard) just double tap it
If you use Nova Launcher you can use the double tap to turn off gesture.

Thanks... sometimes a long press takes a little while to work; double-tap seems instant!
This douple tap feature was available but it stopped 2 days ago. I don't know why or how to set it again.

Screen off Knock Code! wow

Something interrestung i just found on my G6. My device unlock method is fingerprint + knock code as a backup unlock method. Turns out that Knock code works also when my phone's screen is off. All i need to do is just tap the code anywhere on the turned off screen the same way i do it on the knock code squares when my screen is on ( imagine those 4 tapping squares anywhere on turned off screen and just tap your sequence) and voila.
Don't know if any of you guys know about it, but give it a try if you want and please confirm if it works like that on your devices too

So sad to know that you discovered it now. I'm using it since the day one I unboxed the phone. It's the patented feature of LG.

I always thought that in order to unlock your phone with knock code you first had to double tap the screen to wake it, then swipe it to get to knock code screen, put the sequence in and then you would see your home screen :/
I just checked it and it does work with the screen off ?. Nice feature though
I had this on my G2 soo...

This wasted time.. ?
I use fingerprint when I have the phone in hand, double tap + slide the screen for the house (auto unlock with position) or knock code outside my home when the phone is on the back
Yet the phone explains the operation during the first setting I believe !?
This work only with the Lg Launcher?

If the screen is on, double tap only works on LG launcher. Or doesn't matter what you use when the screen is off. Just tap in your knock code and it will unlock.
Drifting from the topic but actually double tap for screen off works partially for any other launcher as well, you just have to double tap the notification bar on the top. It is sometimes hard to hit especially with big finers as mine but it works.
I forgot to say that this actually works not only on the homescreen but on any screen or app you are.
double tap to sleep work flawlessly in Nova launcher with Tasker.. without any root btw
