Screen lock issue - T-Mobile Samsung Galaxy S7 Edge Questions & Answer

I just noticed that if you hit power or home button, then pull the notification bar down and toggle WiFi on or off. It will unlock the phone without a password or fingerprint. Can others try it and post their results maybe it's just my phone

Lol...

No, it immediately asks for the pin. Something's wrong with your phone.. or maybe it's "smart lock" in action? Are you connected to a trusted device?

It's been fine after reboot but that was weird lol

[Q] Major security flaw with screen lock

I have a SIM unlocked and unbranded Desire Z (not rooted). I've set the screen lock to 5 minutes and to require a pattern to unlock.
I've noticed that if I let the phone go to sleep, and then after 5 minutes flip out the keyboard, it unlocks it without requiring the unlock pattern. Does this happen to anyone else?
Yeah, I think this is by design. On Windows Mobile there was a reg key to enable / disable "unlock on slide" Maybe there is similar for Android.

I can't believe this would be by design, it completely undermines the security on the device. How could these be handed out to corporate customers when they can be unlocked by just flipping out the keyboard?
Also the behaviour is inconsistent. If I unlock using the power button, and then turn off the screen, if I flip out the keyboard to wake up again, I do require a pattern to unlock. But if I leave the device for 5 minutes and try again, it lets me straight in.
Ooops, I completely mis-understood your initial post.. The pattern is a sort of PIN screen isn't it..
Ignore me!

I get mixed results. Sometimes mine asks for the password, sometimes it doesn't. I've tried with a PIN, password and pattern. I seem to get the problem more often when the phone has been asleep for a long time, e.g. if I flip it open in the morning when I wake up.
In a way I am glad no one else has this but it's pretty annoying for me!
I get the same problem.
I've also found it to be sporadic. So far i'm thinking there is a pattern depending on what app you have on the screen when the phone locks or sleeps. For instance if its the home screen then it seems to be ok and on waking it prompts for a password. But on other apps it doesnt....
Do you have the same problem if you set the lock time to immediately? Maybe its some kind of problem with the timer.
With immediate lock time I cannot get into the phone without drawing the pattern, keyboard or no keyboard.

I think you might have nailed it there. If I leave the mail app open and lock the screen or let it go to sleep, after a while I can unlock it by just opening the keyboard.

I am testing this and it seems to work properly so far. I'll keep it on lock immediately and see if it happens again. This is really crap though. Most users are going to keep the default of 5 minutes and be totally insecure ...

Slide to Unlock plus Pin security

I just bought the Droid Turbo and I encrypted my phone with a PIN. Now when my phone is in between the screen off and the 5 minute lock time for the pin access, if you press the power button it automatically goes to the home screen. On my 5 other Android phones in between the screen off and the PIN lock out time if you press the power button you still have to slide to unlock. Is there any way to get this back? Or a 3rd party app that will let me do this without disabling the security PIN? I have tried several KitKat and Lollipop lock screen apps but they all remove the pin lock security. I do have the Tasker app but i am unsure how to set this option up. Thanks for any help. If I need to explain the issue better let me know.

I don't think it is available that way with Moto Display. On my Moto X 2013 it doesn't do that either. Because there is a slide unlock on the Moto/Active Display when there are notifications or when the device moves, you slide there to either get the notification or go to the home screen.

I like that feature however, if I press the power button it goes straight to the home screen without sliding to unlock. I dont like that. I want to have to slide to unlock even if I press the power button.

You would probably need a 3rd party lock screen to do that, but I think you'd then always swipe to PIN, after that 5 minutes passed. You can only select one lock screen type on Moto X, so it is either slide OR PIN/Password, but you can't have both. I know what you're referring to, I had it on my Droid X and Droid Razr Maxx, but the only way to turn those on was with the power button. Because the newer Moto phones have Active/Moto Display, I think it works as the slide unlock.
I can say that over time you will use the power button less and less, because you will get used to the Active Display. It's a hard habit to shake, but you'll actually find yourself turning your phone on less to check notifications. On my Moto X I pick it up and see there is a notification (or see it "breathing" an unread notification) and if I press and hold on the circled notification I can see the details. So I can see what the text is, who the email is from, what the tweet is, etc and if I don't care to unlock and view I can swipe left/right to clear it without every actually turning the screen on or unlocking the phone.
If you control the apps that are able to show on Active Display and only places ones you really care about, you'll turn your phone on even less and only for the things you feel are important.
Tasker to add slide to unlock with PIN
I have this reference to use Tasker to do what I want but, I dont understand it. here is the link to the post.

I have Tasker and secure settings just dont understand how to input the code in. Thanks for any help.

I use Tasker and Secure Settings to set/remove my PIN based on my home WIFI connection (it turns PIN off when I'm at home).
Setup your profile with Tasker first, then create an action and select Plugins (or 3rd party, I forget), and select Secure Settings. You'll have a big list of options, Keyguard is under Actions and Password/PIN is under Dev Admin actions. You'll need to enable Secure Settings as a device administrator in your phone settings.
You will probably need to have a profile that sets keyguard when the screen shuts off and waits 5 minutes, then disables keyguard and turns on PIN/Password lock. Then another profile that resets the status to recycle it once you unlock the phone.
Can you post the step by step instructions. I have never used Tasker before and I am completely lost.

There's an option to Lock Immediately on Power or something. In security settings. Or just reduce your time out.

Pin/pattern often needed to unlock?

EDIT: dkotoric has realised this is due to using the double tap to sleep function on some launchers. Locking your device with that prevents the fingerprint scanner from allowing access for some reason.
So today was my first full day with the 6P. It's a truly great device.
A whole bunch of times though when I've come to unlock the device I've had to put in my pattern because it won't accept the fingerprint scanner.
The icon at the bottom of the lock screen that should be a fingerprint is just a lock symbol. If I then lock the phone again and reunlock it works as expected.
Not sure if this is a software bug or some setting I've got wrong. Can't see a pattern for when it does it though. I've switched 'require pattern on restart' off which has made no difference.

I've experienced that on one occasion today. That was after no occurrence in a full day's use yesterday. I put it down to slightly incorrect/incomplete/inaccurate finger print scans when it's set up.
Had no issues yet, used it for 2 days.
I have a pin set for after a reboot and it will ask for pin if I accidentally use pthe power button to switch on.
So far my finger print has not failed once o. My two index fingers.
I set up my finger print with a central / top end / bottom end / left edge / right edge and its worked fine
Been super accurate for me

I recommend using your main finger on different angles rather than using 5 different fingers when setting it up. ?
Sent from my HTC One_M8 using Tapatalk
I've setup each index finger once and it hasn't skippes a beat. I'd setup your finger again and this time move your finger around after every press to get different angles.
Sent from my Nexus 6P using Tapatalk
I haven't had any issues whatsoever. You could setup each index finger as 2-3 different fingers if you want to improve accuracy too.
Still waiting on my 6P, but I do have the 5X. Installed all of my usual apps when I received the phone. Set up fingerprint scanner. For the life of me couldn't figure out what the heck was going on. Every time I would unlock the phone it would go to PIN screen. I had read all of the reviews on how fantastic the FPS was. Started to get really annoyed. In fact I did a factory reset to see if this would help. This time I didnt install apps just set up FPS. Worked flawlessly. Installed apps again and what do you know stopped working again. Then it hit me, I have an app called ScreenOFF. Basically I could touch the screen and it would turn the screen off without hitting the power button. Uninstalled app and FPS worked perfectly. SO, be careful if you have any of these types of app as it seems it screws up the ability to bypass lock screen
It seems to have sorted itself over night. Hasn't done it so far today. Thanks guys.

what I notice is I use lock app and apex launcher so I have it set up to double tap on screen to lock the device. If I lock the device using this method I can no longer unlock the device with my fingerprint. I have to use the lock pattern. Then I have to lock the phone again via power button in order to use fingerprint scanner?

Holy **** you're right yeah that's been my issue the whole time doing the same with Action Launcher. Been so used to using it it didn't occur to me that's the cause. That's annoying.

I have your issue but I am not using any sort of double tap to lock apps. also I am using google now launcher.
Yea this happens when you use a third party app or launcher to lock the device via a double tap on the home screen. I set up a gesture in Nova Launcher to lock the device via a double tap on the homescreen and when I do I cannot unlock the phone via Imprint. There is just a lock symbol instead of the Imprint symbol and the only way to unlock it is using the pin. It seems that right now the only way to use Imprint to unlock the device is when you lock the device using the power/sleep button. Using any 3rd party software without root access to lock the device will only let you unlock the device via the pin instead of Imprint.
EDIT: Everything works fine with root access. If you grant the app performing the screen lock root access then you will be able to lock the screen with say a gesture like double tapping the home screen and then you will still be able to unlock the device via Imprint.
I had this issue as well where my 6P would ask for my pin after using the fingerprint scanner. It would do this many times per day.
What I have found to stop this from happening is removing the administrator rights from all the apps that uses it to lock the screen. It seems that the phone will ask for a pin when a 3rd party app locks the screen.
So I'll just rely on Android locking the screen on its own vs entering the pin so many times a day along with the fingerprint scanner.

Are you just using nova as far as root access? I'm so used to just having greenify lock the screen, but I'm having this issue

I'm actually using loads of root apps including Greenify. (Though I'm not using greenify anymore) Everything is working fine. Are you having the issue when locking via a greenify gesture? I didn't even know Greenify had a screen locking gesture lol. Or do you mean the Imprint issue occurs after Greenify puts the device to sleep automatically?

Greenify has a widget that will hibernate and shut the screen off. I ended up finding this app that will shut the screen off and allow me to use the fingerprint to wake/unlock the device. :good:
So far, the only 3rd party app that I've found that can shut the screen off without root and without needing the pin again is Gravity Screen https://play.google.com/store/apps/details?id=com.plexnor.gravityscreenofffree&hl=en
It has a few widgets that you can link your double tap homescreen gesture to. Specifically, I'm using Lightning Launcher and link the double tap to the "Off" shortcut. The other shortcuts will lock the phone and then you'll need the pin again instead of just the fingerprint.
However, I think the way this app accomplishes this is to first blank the screen off with just a black overlay and then set the screen timeout to around 10seconds (it sets it right back to whatever you had before by the time you wake the screen again). So far, I haven't had a problem with this since the app also has "in pocket protection" in which it will keep the screen from turning back on if the proximity sensor is covered. So if you double tap to sleep but then put it in your pocket before the 10 seconds is up, it won't turn it back on. If you have it sitting on your desk, you can double tap to sleep, but then tap again on the black screen within the first 10 seconds to see the navigation keys again. This also has the weird side effect of not being able to use the fingerprint reader during those 10 seconds, because technically the screen is still on. This was a little unsettling at first since I couldn't figure out why the fingerprint reader wasn't vibrating when I thought the screen was "off". To me, it's not that big of a deal so it's fine with me.

Lock/Unlock Issue

Anyone experienced this? I'm using the imprint to unlock my 6P. Then after some time while pressing the power button, it supposedly locks the phone. Yes the screen turns black as it should be, but I was expecting that after I unlock it, with the power button, the password does not prompt. Anyone?

Check under lock settings whether, "lock screen immediately" (on press of the power button) option has been selected. If it is set to lock after some time, the phone will be unlocked and hence it will open up if you press the power button without a password prompt.
Here's my current settings. Will try the one you gave.

Ok, seems like your lock immediately option is selected. Do you have the smart lock feature turned on? otherwise, you shouldn't be having this issue.

Fingerprint security problem

Has anyone else had a problem with the fingerprint security. When my phone is locked and on lock screen I have phone and camera app in the corners. If I open the phone app it doesn't ask for a fingerprint scan and I can make calls then if I back out of it the phone is unlocked never asking for a fingerprint or password. Why have the fingerprint for security if all you have to do is open the hone and then hit home button or back button.

I think your settings might be off.
On mines it askes for fingerprint. If not thena patten is needed.
If i swipe up the camera or double click home button. It loads camera and i can take pictures. When i back out it goes to lock screen asking for FP.
On the dailer tho.
It will not open until i do my FP or lock patten.
If i do 911 call it will, load the dailler then hitting the back button brings me back to the lock screen
Mine doesn't do this.
