Screen lock/unlock dodgy

I am either going nuts or this is a common isue:
Normally when you tap "lock" on home screen the brightness diminishes and the phone is locked. To unlock, you have to tap "unlock" on the lower left side of the screen, hen you get a message telling you to tap again unlock in the middle of the screen and its unlocked.
Well, my Polaris only does this sequence sometimes. Especially if I let it go in standby for a couple minutes, as soon as I press any key I get another story:
In lower left corner of screen I have the word" cancel". Tapping it doesn't give me another "unlock" button on screen and the phone remains locked. I have to put it in standby from the power button and then try again to get the normal unlock behaviour.
Anyone else experiences this?

Nobody? So everybody's unlock feature works like it should?
Then I think it's reset time for my Polaris....

I personally don't use, the device lock feature... Just the standby, whith the HW buttons off... and it works just fine for me

I have noticed that when you press the central button in the TC, what you describe is what exactly happens. But this happens to me only when I do that. If a tap the screen without touching the button, I have the normal behaviour.

Yes, exactly.
@gnick: if I use the standby with HW keys lock it works ok for me also.
The issue is only with the HTC Home lock feature and the central key

Yes, but very rarely and even then when I press Cancel the normal lock screen resumes and I unlock in the normal way. I have "Do not lock all buttons" selected in the Key Lock settings. Don’t know if this is significant.

2 stages for screen lock?
I use my TC while riding motorcycle, so I want several apps (TomTom, gps tracking [gps.run]), music [was WMP, but now Coreplayer] and TellmeText) running and the screen off so as to save battery power.
If you press the power button when key lock is on it will turn the display completely off, and *most* programs will keep running. TomTom is a notable exception- it stops working, presumably because it can no longer access the gps?. But better behaved/next generation GPS apps such as run.gps continue to run. WMP, bless its pathetic cotton socks, seems to work sometimes!
Are these inconsistecies uinique to my unit, or known quirks?
Anyone suggest a app that will turn the screen off and allow ALL open apps to run, including TomTom?
Thanks

I don't know how you're operating any of the buttons on the TC with riding gloves on!!

anyone got anything more useful to add to what was a serious comment/Q

Man, the battery life sucks on this device So my quest on how to turn the screen completely off and lock the keys properly while running all software (especially GPS based such as TomTom) continues....
Anyone know of a 3rd party app that will do this?
I have not read all 200 pages, but it seems there are mixed results for running S2U2 on the Touch Cruise (http://forum.xda-developers.com/showthread.php?t=353008) ? Anyone having success?
Thanks

I know its late but I just saw this and thought I would mention that I managed to over come using TomTom without the device being on. However it doesnt save much on power as the GPS device need power to work.
But I using a simple function I wrote in my application to lock the device using the standard device lock API calls and then rather than switchingthe device into sleep mode (off) I switched it into IDLE mode, which is basically just switching the screen off, the device lock prevents any unwanted button presses.
The power button would just return this back to normal.
I have not yet worked out how to stop the device brightness changing when the screen lock is enabled on the device... :/ Which is my next task.

Ramakin...
well that would be great because even saving having the screen dimmed during lock would help battery life. And, pressing the power button to resume would be MUCH easier than stabbing around at in the sun trying to unlock the screen. It would also make TomTom behave like all other 21C GPS applications, i.e. run on idle.
So, can you send details?
During a recent motorbike trip where I just used TomTom and tracking software (even turned the phone off) I was SHOCKED at how crap the battery life was

[Q] Disabling auto lock

Hi,
I'm using a Galaxy S running a froyo custom ROM.
I was wondering whether there is a way to disable the "auto lock" feature of the phone?
The display can still shutdown based on the selected screen time-out time, however, the phone should stay without getting auto locked, unless its explicitly locked.
Ideally, it should be like in the Nokia 5800, where the screen switches off after the given number of seconds, however the phone stays unlocked (unless its locked using the hardware button) and the display comes on when the screen is tapped/touched.....
Is there any way something similar could be done with Android?
Thanks in advance,

Look for an app in the market called No Lock. One click on the app toggles the auto-lock on/off and it's auto-loaded every time the phone boots up. Couldn't be easier simpler.

Thanks for the reply.
Actually, I'm using "no lock" at the moment.... What I'm ideally looking for is a way to bring the screen alive just by tapping on the screen. Even eith "no lock" still you need to press one of the hardware buttons to awaken the screen....
Maybe this is not possible in Android ?

I don't think it is...
But even if it was possible, why would you want it? It'd get triggered so often any time you brushed up against it, wasting battery and launching apps while in your pocket or something.

try Extended control

I also need an app or a tweak or something that let me set the screen timeout, withOUT autolocking, but also withOUT disabling the lockscreen, so when I press the side buttons the phone locks.
I've been searching for days with no luck. Any help, please?

App the turn off the screen but not lock

Hello everyone,
I have been searching for an app/widget by which I can turn off the screen but not lock it. This is because my device is under a corporate policy that requires a complex password if it is locked. (the lock is enabled after 20 mins of inactivity). The apps that I have tried have all turned off the screen and locked the phone.
Any suggestions?
Thanks,
Sayantan
PS: Needless to say that all this effort is to save the power button from wearing out!

Sorry, but with a corporate policy, you will not be able to dis-able the lock, on screen turn off, and password on unlock. The only way is to see if your corporate admin is willing to change the policy for you, on your phone, but I would doubt that, considering this is a mobile device connected to a corporate network in some form or fashion.
It is not the apps that do this, but the underlying settings within android that the corporate policy alters.

Thanks Jim.
I actually hooked up to my corporate server only recently, but I've been searching for an app even before that. My screen off timeout is 2 mins and screen lock (pattern & now password) is 20 mins. What I was looking for was to turn off the screen. But every app I found also locked the device and I had to enter the pattern or password. This was even before the policy enforcement.
The app comes in handy when outdoors where you might need to turn screen off immediately after use before pocketing it but not turn on the password.
Thinking of writing one myself now as my power button might already be feeling its age!
Thanks,
Sayantan

Since you want to save your power button, why dont you activate ' volume button wake screen '?
If you're on JB leak the type *#*#6686#*#* in your dialer and it'll take you to a secret laboratory menu. select Volume Wake screen and then you have to press one of the volume buttons to do the same.
Not sure if this works on ICS but you can always try.

Already have the volume rockr wake by editing the build.prop and key layout files. Was not aware of this menu. Thanks for sharing. But what I am really looking out for is an app/widget which just turns the screen off (similar to screen timeout) but not lock the screen (as in security timeout).

Hi @SMONDAL84,
Have you managed to find/program smth that solved your problem? I'm looking for exactly the same thing for months. I've searched the whole Internet (you'll have to trust me on this one) but all apps and widgets always lock the screen while turning the screen off. I'm no programmer, but I'm suspecting Android does not allow this.
Well, if you ever try to program smth, here's a suggestion: configure your power button to don't lock the screen and make some kind of shortcut that simulates the power button press.
I know it's been years... But please someday come back to this thread and let me know if you ever found anything

An app to turn off the screen WITHOUT locking.

Hi All,
I was hoping you guy might be able to help me out.
The LG G3 is awesome, i love being able to turn the screen on and off without using any buttons.
One bit that i think could use some work is that currently, when the screen is on, you can tap the notification bar twice to turn the screen off, however, i find that this doesnt work so well all the time.
I have Nova launcher and i wanted to link a two finger swipe gesture with an app to turn the screen off however...
All the apps on the store only seem to offer you the option to turn the screen off and lock the phone immediately at the same time. Does anyone know of an app that will let me turn the screen off, but NOT lock the phone immediately, and just leave the lock settings to the system defaults.
It seems pretty straight forward but i've tried about 30 apps on the store and all of them only screen off and lock, none allow you to do it without locking the phone immediately.
Any help would be really appreciated!

Thanks for the idea. I just tried and had no joy. It can trigger an action when i turn the screen off myself, but it wont turn the screen off for me.
Any other ideas?
I feel like this is so straight forward and that i'm just being super dense - im hoping someone points something so obvious and straight forward out that i missed!

You could try an app like Button Savior. https://play.google.com/store/apps/details?id=com.smart.swkey.nonroot
It has the option to swipe from the side to bring up the buttons, and from what I understand, the power button on it is exactly the same action as pressing the power button on your phone. You could tweak it to try and get it to the solution you want, but I think at least the button should be what you are looking for.

My phone seems to do the same action either way. I think I know what you are talking about. It seems that on previous roms, the screen could go dark, but if I woke the phone back up it wasn't actually locked. What about this app? It seems to distinguish between the two.

I use "No Lock" when I want to switch off the phone but bypass lock settings when I turn it on. Is that what you mean?
https://play.google.com/store/apps/details?id=org.jraf.android.nolock&hl=en

Hi, Thanks for the suggestion... The problem with that app is that the phone won't lock until I go back in and disable it... I want the phone to use the same system timeout so if I do leave my phone lying around it will lock after 3 or 5 minutes on its own.

Take this.
Note: Needs Root

Not sure it it covers your needs, but I'm using SkipLock combined with Gravity Screen
SkipLock let's you bypass the lockscreen (and pincode) when your phone is connected to either a trusted WIFI network or a trusted BT-device (carkit!).
As soon as you get home you'll turn on your screen and you the lockscreen as usual, but from that point on it's lockscreen free until it disconnects with your wifi network.
So when you turn off the screen the screen goes black, but as soon as you turn it on again you'll see either the homescreen or your last opened app.
It works really GREAT!
Gravity screen is not needed but makes it even easier. It automatically turns your screen on when you pick up the phone, and turns it off when you place it down (configurable). It also features Pocket Mode so it will turn the screen off when you put it in your pocket and on again when you take it out. Worst part was getting used to NOT press the power-button anymore

Hi, Thanks for the suggestion - i just tried the app and it has a non-root version, but that just basically turns the screen black, leaves the notification bar and navi buttons and doesnt actuall replicate pressing the power button.
I cant root my phone either as i need to use banking apps and these dont work with root.
Any other ideas?

This sounds like a cool set of apps, but I'm quite pedantic about my phone and the way it uses battery and with all the sensors working. I'm not sure its right for me, but its cool none-the-less.

Skiplock doesn't use up any battery. Gravity MIGHT, but there are options to choose that use up more or less battery.
Don't know about needing root though...

Hi, I have been looking for this too....no solution? I use the trusted places and devices to keep my phone unlocked when i am home, and when in the car (connected to bluetooth) but of course turning off the screen also locks it.

SkipLock isn't compatible with my Lollipop G3 - any solutions that work on Lollipop? I've been using Tasker but somethings it messes up things a bit so I would like to try something else

Dimming and screen shut off when on call

Can't for some reason find an option anywhere on the phone to stop this from happening. Every time I'm on a call after about 10 seconds the screen will dim and a few seconds later goes to black. Can tap on screen 2x to wake it up again but I don't want this to ever happen. Not connected to full device shut down that I have turned up to 5 mins so has nothing to do with that setting. Can anyone assist and help me stop this form happening all the time? Many thanks!

Not sure then because that was the only thing I could find.. Maybe it's a setting that we don't have control over.. I do know that the screen is supposed to shut off when it's close to your face and the reason being is so that your face isn't pressing on stuff and making the phone do things you don't want it to be doing.. My moms face sure does seem to disable a lot of stuff like fast charging and even turning the screen brightness so low that she thought it was broken haha..

HA. No, phone is on a desk, not near my face. But yeah most phones nowadays do that. Thanks for trying tho.
Anyone else with any thoughts?

Tried replicating the problem on my end. I called someone, enabled speakerphone and put the phone on the table.
The screen indeed turned dim after 10 seconds and turned black afterwards. It bypassed my screen timeout setting which is 5 minutes. The phone app is in the foreground. Double tapping the screen wakes it up.
I minimized the phone app; the homescreen is now in the foreground. It adhered to the 5 minutes screen timeout setting.
I guess the temporary workaround is that after you answer the call, exit out of the phone app.

Hi. I had the same problem and found the solution using third party application: Screen On Call from Google Playstore: https://play.google.com/store/apps/details?id=com.vorlan.screenoncall.free
It is compatible with Samsung dialer. On the top later you have small button to prevent screen going dark or to disable it. Proximity sensor is working without problem when you hold the phone to the ear.
