Is there a screen lock that actually locks the screen? - General Questions and Answers

I have tried lots of different screen lock apps, but none of them does what I want to. Just today I was out checking my lobster pots, and I got a business call on my bluetooth headset. The damned idiotic thing is that when that happens, the screen will actually turn on and show the caller info stuff. And of course in my rain gear pocket it manages to press the buttons, so the call is suddenly on speaker phone instead of BT. Almost lost a contract on that one... Put it back into my pocket, and another call without incident. But when the call is finished, the screen is unlocked, so it starts pressing lots of buttons. I almost sent an SMS to a contractor with "umumumumumumumumum" for four lines! So I need a screen lock that actually locks the screen. Preferably so I have to press for instance power and then a combination of buttons to unlock it. All the apps I have tried have some idiotic slide menu that wants to show me my music player, change theme or something like that. And the built-in screen lock has had me call the Norwegian version of 911 from my pocket several times before I gave that one up. SO can anybody please tell me about a screen lock app that ACTUALLY LOCKS THE BLOODY SCREEN? (Sorry for shouting, I'm quite annoyed...)

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

Problem with hitting screen buttons when pulling phone out of pocket

When my phone rings, the screen turns on. It doesn't matter if I lock ir or not. The Answer and Ignore buttons are still pressable on the screen. Is there any registry setting I can change to make it so the screen stays locked when the phone rings?
I still want to have the option of pressing the Answer and Ignore physical buttons on my phone, but I keep accidently hitting answer or ignore on my screen when pulling the phone out of my pocket.
Thanks
If you install ACs Slide 2 Unlock then you will need to slide to answer or ignore a call. Should stoip the accidental pressing of on screen buttons.
That is not an option. It cuts my standby battery life down to half a day. w/o it I can standby w/o recharging for about a week including phone calls. I probably only talk on the phone a few hours a week though.
BTW I failed to mention that I am on WM6.1
What exactly what you like to do?
If you use a regular dialer the phone will turn on anyways.
If you want something else, like S2U2.. you'll have to accept it's requirements.
Tho, I'm not aware of the battery drain issue. my phone's running S2U2 and it's fine.
try playing with the preferences.

Screen goes crazy during call?

Got a new tp2 from sprint. whenever i make a call it flips to home screen then off then back over and over. Also when I call voicemail, the keypad never comes up until i press keypad and while i am listening it goes back to home screen then turns off. whats going on? dam its annoying!
I'm having a similar issue. When ever I remove the phone from my ear while I'm still on a call it goes to the home screen. Very annoying. It will work as it's suppose to some of the time but I'd say 95% of the time I have this issue. Hopefully someone comes out with a fix for this.
Me too (I'm on TMobile). Also, at the end of the call when it asks if you want to add to contacts, it flips back to home if you don't respond fast enough. But the worst is when I'm dialing in for voice mail and need the touchpad; it flips to home and I have to hit the bottom left hard button to get back to the phone.
I assume it's something to do with the way it turns off the touch screen based on the proximity sensor when it's up by your ear, then turns it back on again as you move away from your ear, so no doubt there's a setting somewhere to adjust that.
same here... during a call the screen goes on and off several times. may be light sensor.... who knows
anything that prompts you to make choices by picking numbers becomes a pain unless you use speakerphone. really hoping for a fix
I have no clue if this will last but I changed the setting to lock the phone if it's unused from 30min to 1hr and that seemed to work for now. Changed it back to 30min to double check, it happened first try during the call but worked properly after.
the way its supposed to work is, when you put the phone to your ear the screen goes out when you pull it away it will come on to the call status screen(not the keypad, unless you push keypad then it should stay on keypad,but if you put it to your ear it will go off, when you pull it away it will come back on to the keypad.)this feature is so you do not push buttons with your face.
Same issue...
Orginally seemed to keep on the call status screnn, but now moves to the home screnn when pulled from head.
Any fix would be apprecaited...

TP2 locks for no apparent reason??

I do not have auto lock turned on. I did load the VZW "clean up" cab. I can't figure out why sometime when I pick up the phone the lock is on, and other times the screen is simply turned off. I never hit lock, simply turn off screen or let it go off automatically.
Anyone have an idea?
Thanks.
Are you sure you are not hitting the top button accidentally. That button will turn off the screen.
I do use the top button. It only turns off the screen though, not locks the device. I can use it, then hit it again minutes later and the device is fine. But sometimes I'll put the phone down or aside for a while, and when I pick it up to answer a call or something I'll find it has locked itself and I have to press the soft keys.
hmm... sounds strange, I gotta go with what the 2nd guy said, I will sometimes lock the device myself (the soft key for it is on the home screen after all and it's VERY sensitive). About the screen turning off, you sure it's not just going into it's timed sleep/standby mode?
hopefully this will be of some help...i too had this problem and then i realized what the cause of MY problem was...whenever i would receive a phone call and would let it go to voicemail, when i would wake the phone back up it would be locked...i cant remember if the same thing happened when i answered the call but i know for sure it would do it when i pressed ignore call or mute ringer and let it go to voicemail...SOLUTION:i downloaded a cab called disable auto lock (or sumthing like that) and it fixed the problem...hopefully that helps..

I've been trying to figure this out as well and came to the same conclusion. My screen is off, I answer a call, and when I hangup my screen is locked. I did a quick google search for disable auto lock and didn't have much luck. Can you post the name of the file and where you got it? Thanks
Not sure where I found it, I think PCGeeks, but it was called Disable_Auto_device_lock.cab
HOWEVER...it did not work for me. I may have to cold reboot (from scratch) as I've tried so many different cabs, things are getting messed up. I'm trying to hold off for the ROM update.
The phone will automatically lock if you miss a call. Sometimes if you pick up on the last ring the phone will consider it a missed call and still lock the phone. That has happened on my 6700, my 6800 and now my TP2, but this is the first phone that locks after a missed call. I actually like it becuase since I dont have a S2U2 or 6.5 on the phone it prevents butt dialing if I leave my phone in my pocket or soemthing.
I have noticed the same issue. I also noticed that it did not happen before I had installed the clean up cab. I had thought that the lock button was being hit while the phone was in my pocket.
Although the "Disable auto..." didn't work for me, I down loaded and am trying S2U2. So far, and if I'm not mistake, It did not lock me after a missed call, or answering a call.
I'm going to play with it for a while. Had something similar before on my old Q9c so if it works, great!
I just hope all these friggin cabs work when I update to 6.5, or I may not! The only real pet peeve I have about the TP2 is earpiece volume. If the cab volume booster doesn't work, I won't upgdate!
I have this issue as well. It seems to lock if the person that calls me hangs up before I do. It also locks if I ignore a call. I have had it lock in the middle of a call as well. Really annoying if I need to use the onscreen keyboard to enter information during the call.
I hope someone can find a solution for this. So far, it's my only complaint about this phone.
Well, I've been using S2U2 now for a couple of days. Getting to like it! My screen no longer locks, and I kind of like the Iphone type unlock. When a call comes in 2 nice large buttons for either answer, or end (ignore).
You may want to try it.
Mine does the occasional random lock also and when it does, it wants a password that does not exist. IF anyone knows what the standard password is, please let me know. I don't have one set and need to reboot when this happens. Really my only beef with the phone which hopefully gets fixed in 6.5
I have found that if I receive an SMS the screen will come on on its own. In those circumstances I have seen it lock the screen afterwards.
I am thinking it is a failsafe put into the phone for accidental button hits after the phone wakes up from certain activity but could be in a pocket.

Question S22 Ultra keeps dialing emergency number

I got the Galaxy S22 Ultra in July of this year and since then, it has dialed emergency number more than 5 times. I have no idea how to stop it. I have:
a) Removed the phone dialer icon from lock screen.
b) Unchecked the Emergency SOS option.
c) Unchecked the "Wake Screen on double tap".
But, for some reason, the screen still keeps waking up when the phone is in my pocket and particularly when I am going up/down the stairs or on a treadmill. The second observation is that it does not dial 911 but dials 112. Then I get a call from the emergency responders and I have to explain to them about the phone.
Phone is non-rooted, Android 12 and upgraded to Android 13. Problem happens on both.
I have searched on Google but cannot find anything relevant. I have no idea how to stop the phone from dialing emergency number. Please help...
Prior to S22 Ultra, I has S20+ and it never dialed emergency number.
Thanks,
Arun
check whether the power button have issues. check by dialing *#0*# and tap on SUB KEY.

What is supposed to happen? When I pressed the SUB KEY, the phone screen turned a bright grey. Pressing the back button, the screen turned bright purple. Pressing the back button second time brought back to the original screen.
If I dial *#0*# and press the power button, the screen turns bright red. Then pressing back button turns the screen bright purple and pressing back button second time takes me back to the original menu screen.
Thanks...
Does it turn red without pressing the power key, just wait few seconds to check whether its happening, because if there is a problem with the key then definitely the screen changes to red by itself.

It does not turn red by itself. I waited couple of minutes.

Type in settings SOS, under Safety and you will find an option to press power button to call 911, you can turn it off there.
It is already off but the phone still dials emergency number. It did so again yesterday. I was just standing and watching TV and phone was in my pocket. On closer inspection, I am seeing that the phone dials 112 and NOT 911. 112 is also considered an emergency number.
This has been happening once/twice a month ever since I got this phone. I have turned off every possible emergency dialing but it still does so.
Someone told me that these phones have a feature that when they detect certain type of movement, they assume that the person is in an accident or has fallen down and they will dial emergency number and there is no way to stop it. This is super dumb IMHO.
From what you're describing it seems that the screen gets turned on randomly and it also accepts interaction even though the phone is in the pocket.
I have no idea why would the screen turn on (and allow touch interactions) when it's in the pocket.
Do you have a screen protector/cover or similar that might "simulate"touches ? or maybe a case that pushes some of the buttons on the side ?
You are absolutely correct about screen turning on randomly. Many times, when I pull the phone out of pocket, I see that its screen is on and dialer is on emergency call screen. It would only take one touch to dial the emergency number.
I do not have any screen protector, only cover. The cover is Spigen and I cannot see a way that it would simulate screen touch. The power key on the cover is recessed to prevent accidental press.
I have another theory. I have configured Samsung wallet and this wallet can be activated by screen swipe from bottom to top. Even when screen is totally off, a swipe from bottom to top activates the wallet and card shows up. This wakes up the screen and brings up all the menus etc. including provision to dial emergency number. I am not sure if friction between pocket and phone screen is causing to launch this screen.
The only problem with this theory is that I had the same setup on S20 without any issues. But on S20, I always used screen protector which might have reduced the touch sensitivity. On the S22, I have tried couple of screen protectors including many brand names and they just do not stay.
Go ahead and test your theory by switching off your swipe gesture for your samsung wallet and see if that'll do it.
I had this exact same problem several times on my Samsung Galaxy S21 5G. Has absolutely nothing to do with the Emergency SOS feature. Mine would call 911 with my phone in my pocket while mowing my lawn...very embarrassing to tell an LEO at high alert barging into your backyard that yeah, you really are okay...maybe hot and in need of a beer, but essentially okay.
What's happening is you have Double Tap to Turn On Screen enabled. A double tap in your pocket or bag will open the lock screen, expose the soft key for making an Emergency Call, and ultimately a couple more unfortunately well placed taps will place the call to 911. Apparently this has become a huge problem nationwide since the Android 13 update late last year. To disable it, in the phone Settings, go to Advanced Features, Motions and Gestures, and turn off Double Tap to Turn On Screen.

I had already disabled double tap before posting here, but it was still dialing 911. Finally, I have put a screen protector film on and did NOT increase the screen touch sensitivity. Normally protective film manufacturers recommend increasing screen touch sensitivity after installing the film. Since then, it has not dialed 911 (knock on wood).
