Iris scanner broken if lcd density changed - Note 7 Questions & Answers

So, get this - lately my iris scanner unlocked the phone only after two successful scans. This is how it goes down:
- press power button to wake up device
- swipe up to use the iris scanner
- scan eyes - PASS
- The device remains LOCKED and a message appears on top - "Tap to use the iris"
- I tap that message, the iris scanning procedure begins again
- scan eyes - PASS - UNLOCK!
It bothered me so bad for the past few days, I wanted to do a hard reset to see if it was a glitch with the rom, but I had the great idea to revert to stock density (whichever that was) with "wm density reset" in adb shell. Then, BOOM!! It worked with only one try! How can that be? I started playing with densities and the conclusion is that the scanner works with only one attempt if you use the stock density. If any other density value is used, you have to scan your eyes twice (with that tap of the message in between) which makes it sooooooo annoying!
The phone is not rooted, I don't use any exchange/lock widgets, etc that would enforce other security policies.
Anyone can confirm this is happening with other models as well? if not, maybe it's only my setup or some apps I have or just a bad rom and a reset would clear it.
BTW.. I hate the pin enforcement while using 3rd party lock apps.. as far as I know there's no alternative, right? Tried Good lock but 1) I don't like it a bit! and 2) it still requires pin while using nova gestures to lock... so....
Anyway.. lemme know on your thoughts on this situation.

normal Lock Screen vs Locked Lock Screen behavior & trigger

I just want to get this straight because I actually thought the encryption settings on the phone were leading to the wonky behavior I noticed about the standard swipe away lock screen and a protected (PIN or whatever) lock screen... that led me to waste hours while the phone encrypted & then eventually screwed up during the decryption of my memory card.
Basically, the standard unprotected lock screen can just be wiped away - everyone knows that. But on every Android device I've owned up to this one (Hero, EVO, Nexus S, Photon, Evo 3D) when you set up a password lock you can set how long a time period passes before that actually kicks in. It seemed like this phone was no different, at first. I mean, there's a timer setting under the password lock options.
However, what I've been able to figure out is (and mentioned in another thread) the moment you set a password protected lock screen it replaces the standard swipe away lock screen all together. For reference, on other phones even if the password lock is triggered, when you turn on the phone the first thing you see is your standard lock screen and whatever information you have there - if you choose to swipe that away the lock screen you actually have to unlock is there. One of the reasons I don't like the implementation on this GS2 is because I actually like the large easy-to-glance clock and information on the lock screen (and missed call, msgs updates, etc). However, that's besides the point, which is that there's a setting for the password lock Timeout - which is screwy because it only takes effect if your screen turns itself off (on the timer set in the normal display screen timeout settings). If you turn the phone off yourself, the password protected lock screen is activated immediately.
I've found that having a 1-2 minute screen timeout is perfect because it lets me either be distracted for a bit while I do stuff on the phone (watch tv?) or try to show someone something on the phone without having to worry about it turning off on them. Normally it's not a problem because I instinctively turn off the screen myself when I'm done using it. In the few days I've had this phone I don't WANT to turn it off because I know I'll have to unlock it again. I usually love the security of a password lock but this seems inconvenient and, well, stupid.
So no password lock = lockscreen with useful information at a glance.
Set up a password lock = ^^ useful screen gone.
Password lock timeout only applies to the screen auto-shutoff = if you manually shut off your screen you HAVE to unlock it even if you turn it on a moment later.
I haven't really seen anyone say anything about this and I guess I'm a bit surprised by that. Again, one of the first things I did when I got the phone was transfer a larger capacity memory card to it that had a number or picture albums and movie transfers to it - then during the time I set up the phone I chose to set up a password lock, then encrypt it (took about 5 or 6 hours!). Since I did these things back to back I thought the encryption was the reason I had to unlock the phone almost every single time I turned it back on. It was only after I was playing with the settings (and eventually had to hard reset when the decryption process screwed up) that I see it didn't really have to do much with that at all. Well, aside from the fact that encryption requires a password lock, which leads to this whole thing. So anyway, yeah - that's like one of my only complaints about an otherwise killer device.
I'm gonna look into the framework when I get home. I remember seeing a bunch of lockscreen settings and triggers. Maybe its just a matter of changing a "true" to a "false"

[Q] Disabling ring swipe unlock

Guys, have a new One X. Am gonna leave it on the stock rom for a few weeks.
How in the name of god do you disable the ring swipe unlock screen?
Even when I put in none, it's still there. When I put in PIN unlock, I have to swipe the ring first, then put in my PIN. It's seems pointless
Thanks
just unlock it, you will get much better performance using arhd rom and do things like adfree (remove ads from free aps) and reset minfree values for multi tasking, etc.
let me put it mildly, the stock rom sucks,
You're confusing device lock with screen lock. If you only had a pin (device lock, for security) you would be forever unlocking and entering the wrong pin while in your pocket.
The ring part (screen unlock, to prevent unwanted input) can't be removed without modification.
Thanks. Looks like customised rom it is so!

Right, I unlocked it and stuck Android Rev. HD on it. So far so good. Seem like a nice ROM, even for the lack of bloatware coming from the stock ROM.
I can't find this customization. Does it exist? Am I stuck the ring unlock?
Thanks
I for one would also like to disable the ring lock seems like overkill as you still have to press the volume button to activate the phone
so these are the precautionary steps:
1. Power button
2. Swipe Ring
3. Security feature (Facial Recognition, Pin, Pattern)
I think as @flanobrian stated we want to cut out part 2 of the process
its just abit of overkill that I would like to control
Yes, the problem is, I've the phone set up for Microsoft Exchange for my work emails, which requires me to also put in a 5 digit pin. It's a pain in the ass have to swipe the ring and also do the pin.
Android always has a lockscreen so you will always have to unlock it and then enter your pin, regardless of Android version

My previous Galaxy S didn't have that. All I had to do was hit the home button and the enter the PIN?
i dont know if this is what you want but try this to get rid of (ring unlock) go into settings - personalize - then lock screen styles and go to the last one it is called
No Lock Screen and apply
i did this and now no longer have to use the ring just power button and im in
hopefully i read this right and
hope this is what you wanted

[Q] Widget Locker Help

I have been trying to get Widget Locker working on my One but have hit an issue. I am thinking I may not be able to fix this without Root but I wanted to run it by the community to verify.
I have my phone linked to an Exchange server that forces a 4 digit pass-code onto the device. So from the default lock screen I swipe up and then get the keypad to unlock the device.
Widget Locker replaces the main screen and 60% of the time when I unlock the device it takes me to the keypad directly.
The other 40% of the time is the issue. When I unlock from Widget Locker it takes me to the default screen where I would swipe up. From this point I can ether swipe up and unlock or shut off the screen. When I try again it usually works perfectly.
Is there any way to get consistent behavior from Widget Locker without root? What I would expect would be to unlock and be taken to the keypad 100% of the time.
I would love to use widget locker, but I always get a 3-7 second delay with turning on my phone. Sorry I can't help you.

Go into Settings and set the HTC lockscreen to none. It forces the phone to only use WL, and you never see the stock lockscreen. Works for me,

That kills the security on the phone. We need to have ether a pin or password unlock to secure the device. Even without it I would want a pattern unlock at the least to keep it somewhat safe.
I expanded my search a bit and this seems to be a common problem on phones that have any sort of lockscreen security. What I cant understand is why it does work some times, but not others. It does not appear to be a timing issue but I cannot narrow down what else would randomly (apparently random) trigger the stock lock screen yet work other times.

No, it doesn't. The HTC lockscreen and the Security lockscreen are two different things. You can have the HTC lockscreen set to none, and still have the option to unlock with any of the various lock methods(i.e. PIN, Pattern, Face Unlock, etc...) I know this is true because I use it everyday. I use WL, have my HTC lockscreen set to none, and still have to enter a PIN to unlock my phone. And have no delay when using WL once the phone is booted.

And I am an idiot. You are completely correct. I am trying it now, thank you.
Edit: Working like a charm. If anybody else is having this issue the setting is under Personalize, lock screen style.
Thanks again!

Screen off and lock - Without button?

I'm used to switch off the phone tap (or swipe) of the screen, without using the power button. But this method for HTC 10 is not working.. I tried to put different applications (for example Screen off and lock), but they are in conflict with the scanner - scanner is not working . Does anyone have any ideas?
Custm rom will give you this feature but you'll have to unlock your BL
The only app that can do this is screen lock pro by Prahallad, but it's a paid app.
It's achieves this via a workaround, which has a side effect that the screen is not actually locked until about 10 seconds after u initiate the lock.
Gestures in Nova Launcher can do this. I have it set to lock when I swipe down on the homescreen. The one catch to this (or any other third party solution) is that fingerprint unlock will be disabled until the device is locked with the power button.

Thanx, u method is working...:good: ( Screen lock pro by Prahallad)
I discovered this behavior with the A9 and 6.0.1. What happens with a lock screen app, most will actually lock the phone, then when you try to use something like a double tap to wake, the phone acts as if it did a reboot, and requires a PIN to unlock. You can't use a fingerprint/face etc..upon a reboot...a PIN is always required. All the apps did this I tried.
The way I use a lock screen/wake is to 1) Root the phone, 2) Install Xposed, 3) install Gravity Box for MM, 4) Navigation buttons, 5) then use the Home button and set the double tap to Sleep.
Have to reboot after activating Gravity etc. You need to be familiar with Xposed and the modules/activating them.
Then if you double tap home to slepp. Then, also put your finger on the Fingerprint for example, and it unlocks and goes right to the screen. You can use the PIN/Face etc as well...but the lock programs always fooled the phone into thinking it rebooted, and only a PIN would unlock it..annoying. This method stops that, so you can still have security, and simply double tap to lock the screen, and easily wake the phone/unlock it with a variety of options.
Not sure if this is how you are using it, but none of the Lock screen apps will work. I've tried them all on the A9 6.0.1 MM. Only Rooting and Gravity Box will give you an ability to do something like a double-tap to sleep, without the reboot PIN always prompting you when you do unlock the phone.

I personally use the double tap home on venom rom.. Works well.
Double tap screen will be kernel based, not sure how efficient it'll be on battery so I'd avoid it and use the double tap home key, not a massive difference.

Bizarre BUG HELP: Suddenly Can't set number/ pattern lock without adding fingerprint

Hi there, Please help me with this weird bug in my MM3's lock function. I haven't read about it anywhere else and I did not update or tweak my rooted system in any way so I'm at a loss as to what caused this probleman d how to fix it.
I am no longer able to employ a simple numerical or pattern screen lock. I go to settings, choose and then confirm the number or pattern, and hit accept -- at which point it asks me for a fingerprint (which I do not want to add) and when I hit cancel, the phone remains unlocked. If I hit add a fingerprint and refuse to present my finger, the phone also remains unlocked. This is so freaking weird!
(MM3 rooted but on stock Android 9 PKQ1.181007.001 -- Miui Global 11.0.6 Stable)
Honestly, I wouldn't give a damn as I never use a screen lock except I am in fact forced to use it every few weeks or whenever I want to review my Brave browser passwords. It forces me to set a lock screen in order to see them. So if there's a workaround just to see passwords, that would do me fine.
Because the basic number and pattern locks aren't functioning properly, I wouldn't even consider adding a fingerprint (and in fact, I have never done so. I have a probably irrational distrust of fingerprint, voice and retina security ... plus I live alone so such measures aren't necessary)
Can anyone give me any clues as to what could be causing this and how to fix it or get around it? Or even if there is a way to see my Brave passwords without employing a lock?
Theoretically, I could try temporarily installing a fingerprint lock which I could then remove after reviewing my Brave passwords. But I have an irrational dislike of fingerprint, voice and retina locks and never use that stuff. Moreover, given the basic number and gesture locks aren't functioning properly, the last thing I want to do is try a fingerprint.
