Trusted places on G3 with lollipop not working as expected

I have lollipop and latest google services installed.
In Security I see an option to add smart lock as trusted agents
Then in lock screen options I select 'pattern lock' as my default and set smart lock to disable lock screen when I'm at home.
It works almost as I would expect it would work. At home I still see lock screen but the 'swipe' one with some apps at the bottom. When I try to unlock, it still asks me for the pattern code.
So it looks like at home it adds 'swipe' lock screen on my pattern one.
Edit:
Funny thing but I can click on the bottom icons and it unlocks without pattern and launches the app.
Still, if I want to unlock to home screen, I need to enter code/pattern/password
Is this an expected behaviour?

same issue here
Hello every one,
I tried to sync my G3 Smart Lock with my car using bluetooth. My autoradio has been added in trusted devices but when i try to use my g3 on my car i have a padlocker on my screen and when i click on it i have to do my schema anyway...
Any chance that someone has the solution or is it a LG issue ?
thx for your help
I'm using Lollipop / 5.0 V20A Final KDZ NO BETA Rom

I am having troubles with Trusted places aswell. But, from what I can see in my case, the issue is that it requires the correct location for you to just unlock your phone without entering a code, but fails to aquire your current location. A temporary fix would be an app the fetches your location every time you wake your phone. As far as the bluetooth goes. It sounds like the app is having a conflict with always verifying your connected to the device while using it. Just an idea.

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.

fingerprint not detecting sometimes

OP3 finger print is really fast but sometimes I just can't it to get it work, once it doesn't work it'll not work at all and then I have to unlock using Pattern
Does anyone have this issue?

I found that if on lockscreen there is a lock symbol it won't open by fingerprint. If there is a fingerprint symbol then it works

Not to worry!! While you are registering a finger..... u have to completely register each corner of the finger print.....only then it works from however u put ur finger on it!! I experienced it many times too!!!

Just registry 1 finger 2 times...thats all

But it works always except when there's a lock icon on lock screen.
If there's a fingerprint scanner symbol it works 100%

it wont work with wet finger, wipe your hand

When you register a finger, you have to put all kinds of different parts of the fingertip on different parts of the fingerprint scanner, so that the scanner "knows" your finger in all possible positions. That is what the lenghty procedure is for.

Yeah I've done all kinds of way, rolled it, left, right, top, down.
Does anyone know why there's a lock symbol sometimes on lock screen instead of fingerprint symbol

Fingerprint Problem May Be?
Hi,
Sometimes my fingerprint is not recognized by fingerprint scanner. I have registered two fingerprints for the same finger. Still sometimes it does not recognize.
Is it because still some area is left which is not recognized? When it is not recognized and i put my center of finger on scanner, it recognizes.
Is it fine? Also is it fine if it doesn't recognizes if only a part of sensor is touched by finger. I am using fingerprint sensor first time so little bit skeptical.
I think i am testing it too much just to confirm if it is fine and somehow able to make it fail at some area of my finger. :silly:
Please help.

Please help me guys.

It requires pin after a reboot, then you should be able to use the fingerprint reader until the next reboot.

Its because of security or you can use require pin on boot and it will take bit long for booting

But what about the lock symbol and finger print symbol on the lockscreen, has no one observed this yet?

Been using OP3 FP scanner from last one week. I have 4 Fingers registered it works without any problem. Clean you FPS

I've been having an issue where I would take the phone out of my pocket and the fingerprint scanner wouldn't even vibrate when I touched it. After trying several settings I started putting my phone in my pocket with the screen facing out instead of towards my leg. I think the fingerprint scanner would get activated while rubbing up against my thigh. So far I can tell it's working fine. Everytime I take it out of my pocket it recognizes my finger right away. Also I noticed less battery drain.

I saw it. Often when i unlock using fingerprint the phone gets locked automatically 1 second after unlocking, than the symbol is a lock and i have to use the pattern. Then there is a text something like "For improvement of safety, a pattern is required" really annoying

Is the Fingerprint Scanner perminantly ON?

Hi Guys,
I'm thinking about buying this phone for a friend and need to understand how the fingerprint scanner works.
On my One Plus 3, the scanner is ON all the time which makes it awesome, (but probably eats battery.) :victory:
On my Galaxy Tab S2, you have to press the scanner to turn it on first, which makes the whole process much worse.
Is the scanner on the P2 always ON, (like the One Plus 3,) or does it require a press to wake it up? (like on Samsung devices.)
Thanks in advance. :highfive:

The scanner is always on.. you don't need to wake the phone to use it.. the battery drain is minimal

Thanks Uibon. :highfive:
Is it a physical button? i.e. presses in, or is it just purely capacitive?
My Samsung also has an issue where if you lock the screen using an app, (Power Toggles,) you can't unlock the phone with your fingerprint. Any idea if the P2 suffers the same issue?

It's both. The fingerprint sensor is capacitive and works by just placing one's finger on it. There are also many gestures that work on the capacitive sensor like tap to go back long press to view recent apps. The button is also physical pressing it brings you to home screen and long press brings up Google assistant

Ok Uibon,
So to unlock the phone, do you just place your finger on the sensor (without pressing it down,) or do you have to press it down as well? I ask this as on my Tab S2, having to press down also results in many incorrect reads.
Its a pity Lenovo didn't put a lock screen gesture in the fingerprint scanner like One Plus. It by far the best system I've ever used. :angel:

It works like the fingerprint on the OnePlus.. just place the finger to make it work no pressing the button necessary.

Excellent Uibon, :victory:
Just need to sort out now the issue of using an app to lock the screen and understand if this takes away the ability to unlock next time with the fingerprint.

Just tried screen lock widget and it requires pin to unlock after using it. Finger does not work.

I am using nova prime and double tap to sleep and i can wake from finger print sensor iff you use timeout lockscreen method which means after you double tap the screen to lock the it screen goes black instantlly but the actual full screen lock engages after 30sec allowing the phone to screen to be locked through its own system hence the fingerprint wake works normal. I am not aware of other launchers that have this but nova prime has it.

That's an Android security limitation and all phones do that I believe. I think some apps can "trick" the phone by turning the screen off and let the timeout do the locking but I'm not sure.

If you have root access then they'll work. Else they won't. It's a security feature and uses device admin rights to lock the phone. Which means the device admin should unlock it by the most secure way. That's​ pin password or pattern.
It's not device specific and hence it's nothing to blame Lenovo

You are correct dannejanne. Some OEM's have realised how stupid it is and have sorted it out.
On the One Plus 3, you can securely unlock the phone and relock all with one finger while your phone is on your desk. You can do this better and faster than any other phone. As it's something you do so many times a day, it's time for the other OEM's to blatantly copy this.

Using Gravity Screen to wake phone when you pick it up

I was searching for a way to make Tasker wake phone when I pick it up, so I just have to at it to unlock it. In looking into this, I discovered Gravity Screen, which amongst other things, can wake your phone when you pick it up, straight to Face Unlock. It seems to work well but I'm not sure of the impact on battery. I'm not using it to lock the screen... Really only using it for the one thing.

I've been using this app on my last two phones in order to be able to double tap the home screen on my launcher (Action Launcher) to turn off the screen, WITHOUT locking the phone. For some reason though, this no longer works on the OP5T, double tapping just simply won't trigger the screen off shortcut. Really disappointed in this, are you able to get this to work on yours?
I do also use its proximity sensor feature so that it automatically turns the screen on upon removal from my pocket, and it turns the screen back off once I put the phone back into my pocket, which triggers the angle needed to turn the screen off. That feature still works as intended, and better yet, preps the screen for the face unlock. And as far as I can tell, hardly uses any extra battery.

Hmmm... I use Nova Launcher and I use the double tap to lock the phone. I've never wanted it to not lock. I wasn't aware that there is a double tap action in Gravity Screen? I'll have a look.

It's not really within Gravity Screen itself, you'd have to use the launcher to set up the double tap on home screen to a shortcut. From there, you can pick one of Gravity Screen's shortcuts that allow you to either just turn off the screen, or do a persistent off screen, where you have to use the power button to bring it back on. I believe the problem I had with using the double tap to lock screen feature built into the launchers is that it forces you to have to enter in a password afterwards...face unlock or fingerprint do not work.

Hmmm. Not true with Nova. I double tap to lock and I can use fingerprint to unlock. However, I believe that I requires root for this lock method. Do you have root?

Nope, I don't have root. I did try the same shortcuts with Nova, and it didn't work there either.

have used the app on my old OPO.. now on 5T it's just perfect.. just pick up the phone.. and prepare for landing on homescreen without any tap or button press
does not consume a lot of battery

I've used this in the past as a way to turn on the screen when it comes out of my pocket

This application wakes up your phone, and it works well on my OP5T, it's called "Always on AMOLED"you can download it from F-Droid open source apps, Yalp Store and Google Play. I like that it is low on resources, double tap wake up screen option, lock screen clock, date, battery, custom message and notifications.
