[Q] Important Question for the Lock Screen - G3 Q&A, Help & Troubleshooting

Me and my brother both have lg g3s, and recently I have accidentally reset his phone by guessing the knock code too much, thinking that it would only lock his phone for a few minutes. Now I am afraid that he will try to do the same thing to my phone, and I have no idea how to prevent it from happening. At this point, I think it would be safe to not even have an unlock code. So, I am asking if there is any way to remove this heavily flawed feature.

No you'll just have to not have a password or dont let him have your phone... Would be more sensible

[Poll] Do you use face unlock, pattern, etc?

Just curious about what kind of security people use to unlock their phones. I played with the face unlock when I first got the GN but eventually got too impatient. I'm trying to decide if continuing to "Improve face matching" will eventually make it fast almost every time, or if I should just go ahead and switch to pattern or pin.
If you lock your phone, I found face unlock minimize touching the screen and thus less blur on screen
But sometimes I feel face unlock delay my logging into the phone in case I want to do something quick.... I still prefer pattern unlock

I used to have no pin because I like the stock lockscreen and being able to put SMS phone etc in the slide to unlock. Now that aokp has the option for both I use pin and lockscreen. Feels like iPhone lock exactly

I use pattern..but not for security reasons at all. I got tired of pocket dialing people.

Pin. When you think of the personal information on a smartphone it is a little scary. I have droidlost installed for added protection, but I'll only use a pin because anything else is just to insecure. Most pattern locks can be guessed by smudges on the screen in just a few attempts. Face unlock can be cracked with a bad facebook pic.
While face unlock can be hacked with a picture, no one that finds your lost phone is going to know what you look like. I always thought that was an interesting criticism of the face unlock. My friends might be able to hack into my phone, but that's not really who I'm trying to secure it from.
I also used to only use slide, but I have recently become more and more aware of how much information is available to anyone holding my phone. I think identity theft would be pretty easy if I lost it

Yeah, pin and password are the only two that are very secure, but I just use slide. My mentality is, I'd be much more concerned if someone got ahold of my wallet with all my cash, ids, cards, etc, but I don't put a lock on that. I just keep it with me all the time, same as my phone. I've never lost either and don't plan to! But I do have SeekDroid just in case.
Face Unlock, just so that when I get into the homescreen, JuiceDefender has turn on my Data Connection. Oh, and too impress friends too
Face Unlock.
It is much better than nothing and I don't want to key in the PIN every time the screen is locked.
I never carry my own photo with me other than the one on my driver license which I confirmed would not unlock my phone. So I don't see why people say Face Unlock is useless.
I use a pattern, get it wrong and I have a picture of you emailed to me.
I used slide to unlocked before I installed cerberus, might as well use the features.

Actually it would be very easy to find out. Most lockscreens will splash contact information. If you find my phone you will have my name, work phone number, and multiple email addresses. That is at least three ways to google and find pictures for most people. I would argue that this is the most insecure method possible to lock up your device.

how do you get the phone to send you the pic?
I like to use the pattern, but it gets annoying when I'm just sitting at home texting back and forth, as I have to unlock it every single time. I end up turning the security off lol. Sometimes I'm good and turn it back on when I leave the house.

After enabling Face Unlock, when I touch the power button, I can only see the date, time, and the network name. There is no personal information at all.

Under security settings click 'Owner info' to turn it on. Shows whatever message you want to the hopefully honest person who finds your phone. Only hitch is that if the phone is plugged in it just says "charging xx%" rather than the message. Don't know if that is a bug or if Google just figured that if your phone is plugged in it is probably not lost.
I'm using a PIN because I installed unlock with WiFi and it requires it. When I'm on a registered WiFi network I just slide to unlock.

also, i feel that pattern unlock can be easily seen & remembered by people standing behind you even from quite a distance, as compared to pin/password lock
No. I'm ugly enough and don't need to be reminded of it constantly.
Neat trick though.
i wish there is a slide --> pattern unlock. i want the quick camera access and pattern

Unlock screen shifted

Anyone else having this same issue where your unlock screen shifts so that not all the number pad is visible to unlock the phone? I keep having this happen to me.
I'm completely stock

Time to root!
Whoa. I never even knew you could get the number pad to show up on the lock screen. I have had my lock screen sift before. It happened once about 2 weeks ago. I just reset the phone and it hasn't happened since. Is this something that keeps happening to you?
Unfortunately this happens quite often and requires me to reboot the phone to unlock it.
I had this issue once with the pattern lock as well. Shifted up and right leaving only the lower left exposed and had to reboot.

This has never happened to me on the lock screen personally, but my girl had this happen to her phone randomly one day at work and afterwards she found out her IMEI code on the phone had been blocked, had to send it back in for a replacement.
It's possible if you lose your data connection under certain conditions this may happen. I'm assuming this might also occur if the screen turns on while trying to change it's orientation as this has happened to me in certain programs which required a reboot to fix (this occurred while reading during the 5 second period between the screen shutting off automatically and the screen locking therefore the screen had not yet locked before it was turned back on).
Yes, have had it happen to be as well. Am rooted. Reboot seems to be the only solution.

Happened to me once too, and I'm stock, just a glitch

S3 lock screen pin bypass

The bug that affects the s3 and note 2 works on our at&t s3. If you use a pin for security on your lock screen, you can bypass it by hitting...
- Emergency call
- Emergency contacts
- the home button
- the power button
It takes some timing on the power button but if you keep trying you will get it. It makes the lock screen disabled until reboot and also the notification bar doesn't work but is quite a security flaw.
This is verified on my bone stock unrooted s3.
I have seen this posted in the international s3 forum but not for at&t, so I figured I would share

This only affects touchwiz.
Yeah, guess I'll have to move to cm or another aosp based ROM. Security is sort of a big thing for me. This is sad though I would think Samsung would be pushing a fix quickly with the whole safe for enterprise thing.

Lose the phone... first thing to do is change google account password.
Hopefully Samsung patches it soon! (Already posted in the S III General forum.)
Hmmn I am unable to repro I can get close. I can get back to the home screen without actually unlocking but almost instantly the password screen reappears

It takes some timing on the power button. It took me about ten tries but eventually worked.

I've just confirmed that this actually works (unfortunately).
Now that this method has been publicized on the web, Samsung and our carriers WILL have to roll-out an update (such as 4.2.1) with immediate effect to remedy this flaw.
For an apology, they can also add the Premium Suite in the update for the rest of us who have been ignored.
Has anyone tested this after updating Lookout Mobile Security to the latest version? It's supposed to provide a temporary fix.

Nope. An expert thief will bypass everything.
However,
If the person who stole your phone is a regular guy, your best chance is an anti-theft android software. Don't you want to find who stole your phone?
Anti-theft apps like "Lookout", "Cerberus", "Prey" and "Android Lost" offer a wide range of options for finding or protecting your device: taking pictures of the thief, GPS location, sounding an alarm, locking the phone, wiping the data completely, and more.
Press thumps up if you found this suggestion helpful.

LockScreen Issues

Is anybody else having problems with their lock screen? It stopped working on my phone out of the blue. I tried wiping credentials restarting the phone several times setting up other types of security (pin, password, pattern, etc) but nothing works the phone just won't lock itself anymore it stays unlocked. Can someone please help me? Thanks in advance
Update: I forgot I had stay unlocked at location (home) idiot me I know •_•
Wait a minute... I just started having the very same issue 24 hours now, but I don't get what exactly your workaround was. Could you explain a bit? What is that "unlocked on location" thing you're referring to? Is it about "smart lock"?

Yes, I think that's what he means. He had set the phone to remain unlocked while at home.

Alright, I didn't. I've tried to be a little sarcastic, indeed... Yet, I'm facing this flaw of lock screen not showing nor locking nor doing its thing. Smart lock has never been set on this device, BTW; However, often it briefly reappers after shutting down the phone and restarting it, but not by means of rebooting. So far, NONE of the usual, widespread workarounds (clear caches, credentials or device administrator) is working over here, so I've been looking for a different hint on the subject, to no avail. Sadly, it probably could take years to have the right one, as I can see... But, I'm working on my own; if I don't get bored in the process, end up doing a full OS restore or simply get rid of the phone, then I will let the community know...
