Carbonrom Build 15 Aug 2018 , knockon does not deactivate. Device unlocks in pocket. - Xperia Z2 General

I installed this rom recently and noticed it was heating up in my pocket. When I looked, the screen was unlocked. I checked why this was happening and by accident, the knockon was activated. I disabled this function and the problem persists. Does anyone know how to solve it?
Obs.: The problem is not warming, but the unlocking of the screen because it has times that it makes calls to some contacts, opens randomly and opens some applications ... causing the device to warm up ...

If you're using Auto Face Unlock along with Smart Lock's On-body detection the phone will sometimes unlock right after you hit the power button without locking, that might be it.

Hello, I do not use Auto Face Unlock. That's why I find it strange. I have to use a password or the unlock pattern so that no bull**** happens.

locking the HD impossible when pin is in place ?

Hi,
I have read several posts of issues where pincodes have been set and then the lock doesn't work anymore.....
But, there must be way of locking your phone, right ? I know that pressing the power-button will put your phone to sleep but that's hardly a lock..
Or is this a bug ?
Anyone ?
Perhaps I should mention that I have installed Pushmail, and that a security policy has been set to autolock after 15 minutes of inactivity....
I use sensorlock. You justspin your phone clockwise to lock and anticlockwise to unlock. It uses the Gsensor functionality to completely disable any screen touches

[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!

when i slide mine open, it shows me the unlock pattern screen in landscape

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 ...

Moto Notify incompatible with smart/face unlock?

OK, so I reach to pick up my phone... Moto notify does it's thing and shows the padlock... I swipe down to unlock, and despite being in a well lit area etc I'm greeted by my unlock pattern.
If I wake the phone with the power button, it sees my face just fine and unlocks, no pattern required.
Same for everyone else?

Yeah, what you do is when you get asked to put in your pin you press the back button, do the face unlock, and swipe up to unlock your phone like usual, sadly there's no other way to get around it.
Works fine with smart unlock with a bluetooth device.
Yeah it's fine for when I have the smart unlock for trusted location and trusted bluetooth device (ie at home and car, in my case), but it's bit of a pain that the trusted face doesn't work with it.
Ah well, maybe it'll be fixed in M... but I won't hold my breath :lol:

Fingerprint sensor glitch?

A couple of times since I've had the 6T, when I tapped the screen to bring up the ambient display or lock screen the fingerprint sensor wouldn't be active. The fingerprint icon would be white and putting a finger on it did nothing. The first time it happened, I was using the single tap to ambient display. When the fingerprint sensor didn't work, I hit the power button to bring up the lock screen and the sensor activated and I was able to unlock using a fingerprint.
I've switched to using double tap to lock screen with both face & fingerprint unlock. Tonight when I tapped the screen the lock screen came up but again the fingerprint icon was white, not active, and face unlock didn't even work. I had to swipe up to unlock with my PIN. After doing so, both fingerprint & face unlock have worked as normal.
Any ideas on why this could be happening? Just a random software glitch? Or does device security require unlocking with a PIN/Password/Pattern after so many fingerprint/face unlocks or after a given amount of time?
yes, it happened to me as well.
but i dont think this is a bug/glitch. This happened to me on other android phones as well.
i think this is a security thing where your fingerprint sensor/ face id is disabled once in a while and you can only sign in with your pin/password.

Oneplus 6t new major fingerprint security flaw

The OnePlus 6T's fingerprint sensor can easily be bypassed with this trick. . We have confirmed it working on two phones so far. Phone Unlocks itself via camera and voice from Lock screen, plz some one report..
Please confirm that the phone cannot see your face when you unlock it, and no Smart Lock trigger was active.
This alleged problem does not exist on my phone.

No i turned off face unlock , it just unlocks itself, just open the camera from lockscreen then close the camera app,
no , i turned off face unlock, it unlocks itself from launching camera from lockscreen thn closing the camera app, it bypasses all security locks " fingerprint , pins and face unlock"
We shall wait for others to check. I couldn't reproduce the error at all.
Do not have this problem with mine, are you sure you don't have your left thumb registered?

Either way if this is true. you should be reporting it to OnePlus. Not telling everyone on XDA how to break into someone elses 6T

So if I'm hearing you right, you're saying that by opening the camera from the lockscreen and then pressing your home button, your phone unlocks? Doesn't do that for me, it prompts me for my PIN or fingerprint when I press the home button. Can't reproduce this either... Might reinstall OOS? I'm at a loss for advice on this one.
I can reproduce this. I use navigation gestures, so opening the camera from the lockscreen and then just close it with the right (or left) swipe gesture to go back and you're in the phone. I don't think it has anything to do with the fingerprint sensor.
Edit: now I can't reproduce it anymore strange.. [emoji848]
I'm not able to reproduce this either. Switched to navigation gestures. Turned off face unlock. Launched camera from lock screen. Swipe from side to go back took me to lock screen with fp prompt only, no keypad for PIN. Tried again, this time swiping from middle to go home. I get fp prompt & keypad for PIN. However, with this screen the camera stays open and viewable through the lockscreen, but phone is still locked.
After a few tries I see my home screen but it's only a flash then it's back to my lock screen. It looks like it may want to but maybe I'm doing it wrong. Either way, this looks important enough to report to OP and see what's what.

Tilted phone so it can't capture my face and tried as you've said - running camera and voice commands from lockscreen and phone is still locked, cannot bypass..
So there are two vartiants.
1) Phone still recognizes your face
2) Enabled smart unlock? so phone knows that you are in home and automatically unlocks device.

Nope, i unlocked my friends mobile @ my home...
You sure you have a pin/fp/pattern set up at all?
I've been trying for 5 minutes with gestures and it always just either asks me for a pin or sends me back to the lock screen.
Seems odd but maybe post it on the OP forums instead of here, won't get them to fix it if they aren't aware of it...
Nope. Unable to reproduce.
