[A3 Nougat] Screen unlock issues - Samsung Galaxy A3, A5, A7 (2017) Questions & Answe

Hi all.
I keep having issues with screen unlock.
First it would only unlock via fingerprint and not using pin.
To test a little i then selected pattern + fingerprint and now it doesn't require either except on first boot up. I can simply swipe to unlock. However, if I scan a non registered finger it says "no match".
I'm not connected to trusted devices...
Any ideas what causes this behaviour? It shouldn't be due to removing stock bloatware, right (Samsung, Google, FB apps)?
Many thanks!

It sounds to me like you have one of the "Smart Lock" settings enabled. These override the pattern and fingerprint settings when specific conditions are met: the device is on your body, the device is at home, or the device is within range of your smartwatch.
They should really be called "Smart Unlock" settings. You can find these settings under "Lock screen > Secure lock settings".

Sort of an old thread, but I'm also facing issues with the unlock screen lag. Somehow it is related to the battery saving: since it slows down the CPU, apparently the system doesn't have time to "process" the unlock pattern (or PIN, same problem; and hang me if that process should take longer than a couple nanoseconds), and the screen goes back to black before the unlock is successful. As a temporary workaround, I've disabled battery saving, and now at least I can unlock with pattern or PIN. But the real problem must reside somewhere else. It's not acceptable that an operating system takes that long in processing the unlock.

[Q] Lock screen and unlock pattern

Hi All!
I found a few threads on the Internet in different forums with no answer so I thought I'll ask the pros:
When I'm using Pin or Password to unlock the phone, I get the standard lockscreen display before I can unlock the phone, so it goes:
On/Off Button -> Lock Screen -> Pin / Password
The problem is when I'm using an unlock pattern, the lock screen gets skipped, so it goes:
On/Off Button -> Unlock Pattern
This is very annoying since I like to use the lockscreens mute function without having to unlock the phone. Apparently there is no way of changing this with settings so I was wondering if anyone know of a patch or another way to have the lockscreen AND the unlock pattern?
I'm using the Oxygen 2.0 RC6 Gingerbread Rom on my Desire but this seems to be a generel "issue" with stock Android Roms (Hero Roms and Froyo Roms is the same) - Sense based Roms behave different.
Thx for any hint!

I am having a similar issue and my searching only found this thread.
While at work (2/3rds of my waking life) I use my phone at work to see where my next appointment is. It's very convenient to just glance down and see what meeting I have next by only hitting the power button. From what I have seen there are a lot of apps which will add this functionality to the lock screen.
The problem is when I add a passcode (required by work) it replaces the unlock screen with the passcode screen. I have seen that other Android phones do not do this, but the Captivate does. I've tried four different roms and all have this same behavior.
Is it possible to have the unlock screen come up, and when the phone is unlocked to prompt the passcode? I can't find a setting anywhere and the third party apps like Flylock have a jarring user experience in this configuration.
Thanks

The purpose of the pattern lock is to prevent unauthorized use of the phone. So it doesn't make sense if you put the lock screen over the pattern lock(or combined them) as you, or any stranger, will be able to issue commands(mute, read messages, weather, music etc. there are lots of widgets running on the lock screen) to the phone BEFORE unlocking it.
The security of the pattern lock will be totally compromised.
So the only choice is pattern lock over lock screen. I don't see how this makes anything easier. And I won't go into how it will create huge security loopholes/bypass the pattern lock completely if widgets or anything is allow to run on/over the lockscreen.
Perhaps I am using the wrong terminology, I should be referring to it as the "Unlock Screen" (Settings -> Display -> Unlock Screen). From this screen it appears that you can:
1) View the time
2) Unlock the phone
3) Mute the phone
4) See the notification bar (Vibrate, Battery, Signal, Pending notifications, etc)
I would actually like to add:
5) Next calendar appointment with location
6) Weather
This is all actions / information I want available at a glance and without unlocking the phone. Once I attempt to unlock I would like to be presented with the pattern / pin security. In this way all my private information remains hidden, but the information I use the most often while walking / driving is readily available.
I am also good with anyone else being able to pick up my phone and perform the actions I listed on the unlock screen. I believe this information is available from the unlock screen on the Windows Phone and iPhone (assuming it's your only notification, their notification system sucks).

That PERMISSION to allow you do issue commands to your phone will compromise the security of the pattern/pin lock screen. You need to understand the core concept of the pattern lock screen is to be secure - no unauthorized use of the phone, whether it's as small as viewing notifications to fullon running widgets/apps.
Plus your definition of being secure doesn't equate to everyone's definition of security. It fine for you to display messages on the securely locked phone but it's definitely not for some of my friends who have really sensitive data on their phone.
I was not trying to advocate this behavior to everyone, just wondering if it was possible to set this up myself. One of the things I like about this phone is that everyone can customize it to fit their own tastes.
Actually, I think I found my solution. Flashed to CM7 last night. The pattern screen still had the behavior as the 2.2 roms but the passcode had the behavior I was looking for.
Well the thing is: When using PIN or Password to unlock, you can actually use the lockscreen to mute etc. before unlocking. And using the original HTC Rom, this is possible using unlock pattern, too. Everyone will have to decide for themself if he cosiders this function a thread to security, its just really annoying that I have to decide between unlock pattern and unlock screen even tho it should not be a problem technicaly. Cyanogen guys apparently have this on their list, but with minor priority. I'm really close to moving back to a HTC rom actually...
this bugs me too.. I like the PATTERN cause it's kind of unique and cool plus when you enter your pattern there is no "OK" key you have to press like you do when using PIN/PASSWORD which for some reason annoys me.. I suppose it's another line of defense against prying eyes that make it that much more work to try different pin options.. I don't know maybe it's to annoy them into giving up?.. Anyways, I've opted to use the PIN option because I too like seeing the Lock Screen and any info it has and I really don't see it as that big a security hole seeing the small amount of info on the lock screen.. unless you're running a ROM or app that has popups for messages and such.. and if it really is then Google should make the behavior that you do pattern then to the lock screen. of course I'm sure their reasoning for this is the pattern is a more difficult form of security to breach so there is benefit and no harm from taking you straight into the unlocked phone once the correct pattern has been entered. that doesn't mean we have to agree with the mighty G on this and I'm sure either Devs cooking in the ROM kitchen could change the behavior if they saw the want in the community, maybe a patch could be made or an app that changes the behavior. anyways, that's my $.02
If any of you guys find a solution around this issue please let us know!
Haven't seen any solution yet, how about you guys?

[Q] My screen locks too often (requiring pattern or pin very often). Why?

I'm curious if anyone else has had this issue. I have to enable a PIN or pattern lock to allow a corporate secure wifi network setting to be saved and for something else (I think for my bank app). From the G4 settings it seems like you can set it to NOT lock when turning off with power button (last option), and a 30 minute timeout before it auto-locks. Yet despite that, mine still seems to lock requiring a pattern input and not just a swipe if I leave it on the table for just a minute. What am I missing?
Thanks all!

These settings are under Lockscreen. Right at the end. It should work, unless you have another app controlling locking.
Exactly.. it "should work"... but it isn't. It insist on locking all the time.. Could the fact that I"m connected to said secure WIFI cause that?? (vs just having an entry for it)
You could try going under the setting for Security - Phone administrators. Look if there is something that is controlling phone lock.
I know for my example, I must enable PIN locking, but my phone administrator for that account enables up to 30 minutes before forcing lock. So as long as I uncheck the setting for "Lock phone immediately on power button," my phone will immediately be unlocked within a 30 minute window where I don't need to enter my PIN.

Right, that's what I'm going for / expecting. I have 3 in there, Android Device Manager, Support & Protection (Verizon thing it looks like) and AirDroid. Only Android Device Managers is checked ON. ADM can obviously affect the lock screen and can change the lock password, but I don't see anything else which would affect this timeout being ignored. hmmmm
(Thanks, BTW!)
I was looking at my Smart Lock section and read the blurb about On-body detection, which was the only Smart Lock I had enabled. It says "Just unlock once and your device stays unlocked as long as you keep holding your device or carry it on you." .... "Your device will lock when it detects that it's been set down"..!! So, I've now turned on-body detection OFF as, in this case, it's working against me. Seems it's not too well integrated with the other options (ignores the Security Lock Timer).
If I don't post back, it's probably working as hoped.
Disabling on-body detection has definitely solved my issue with the G4 locking shortly after setting it down on the desk.

Lollipop Quick settings

This has been annoying me lately but I don't know when it started. I'm running 5.1.1, using fingerprint lock (tried also with pin lock, same thing), with a 10 minute delay of locking after screen off. For some reason, in the lock screen I no longer have access to quick settings, even when the screen isn't pin/fingerprint locked (within the 10 minutes). Was this changed on purpose for "security purposes" and now even when you don't want the lock screen protected, you have no access to quick settings?
Is it just me? Or is that the way it's meant to be/has always been?

Fingerprint app lock only

Hello all,
I'd like to use the fingerprint to lock only specific apps without having a lock screen active.
With other smartphones I can do it, with the P2 seems to be impossible.
In order to activate the fingerprint security, I have to record some fingerprints and that's ok. Then I select the single apps I want to lock.
But, if I disable a lock screen the digits scans are deleted, therefore the fingerprint app lock feature stops working.
In other phones when I disable the lock screen, the app lock function keeps working (fingerprints scans are not deleted).
Is there any workaround ?
I only manager to get partial workaround - I set option that the phone will lock itself after 30 min and I used simple PIN to use it quickly if needed and also I use smart lock so it will not lock that often...

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.
