Extend incorrect PIN lockout? - Android Q&A, Help & Troubleshooting

Hello - on iOS, if you enter the wrong lock screen pass code too many times, the phone progressively takes longer and longer before allowing you to retry entering the pass code, ultimately locking it indefinitely after several increases (30 seconds to 5 minutes, 30 minutes etc) . From what I can tell- Android only locks out for 30 seconds no matter how many attempts it seems. Does anyone know a way to secure it for a longer period of time or auto-wipe after x failed password attempts should it fall in the wrong hands and the password is guessed incorrectly too many times? Thanks!

[Q] Lock screen

Hi,
Not sure if this has been asked before, but If a pin number or password is set up for the lock screen, this can be bypassed by pressing the home button 5 or 6 times and will then open up the phone without the need to enter the password or pin. A work colleague found this out by accident and was able to access the phone uninhibited. Is this a feature in case of forgotten passwords / pins or is it a bug. Or can it be disabled? as it doesn't seem all that secure
Mine doesnt do that, tried it several times
must be a bug on your phone
Yeah I though that but another work colleague has the same phone and his does it as well. You have to press it quite quickly it seems to go into the voice control when it comes on and then goes on to normal phone use. I have found other references to it googling, but seems to be relating to a fix if you have actually forgotten the password.
We've been having a fiddle , and now having powered off the phones cold and restarting after setting the pin numbers it has stopped doing it. Up untill now after setting the pin code we hadn't actually powered off completely just into standby. SO you presumably must have to reboot the phone after setting the pin number.
Anyway both phones are working and cant replicate the issue, so hopefully sorted.
Thanks

[Q] PIN passcode error, data wipe work around

Ok so I have a Galaxy 10.1 wifi tablet. I have it rooted with the AOKP ICS release, and my tab is encrypted. What happened is my little brother was messing around with my tablet and it has a PIN code lock screen, he botched the code too many times and now my tablet is trying to do a data wipe. Is there any kind of work around I can do to keep that from happening?
Some more detail, I tried the lock screen bypass app and it didn't work
Really ?!
I used to know that if u typed in the code wrong several times it locks the screen for 30 seconds than 5 minutes 30 minutes and so on
Can you make a photo of the screen to show me exactlsy what it states

Lock Screen "Try Again In..." countdown even though I never failed

(Sorry for posting this to a general forum, but I figured there's a good chance this issue is not model-specific.)
I noticed some strange behavior (henceforth referred to as "the behavior") on my stock 4.1.2 T-Mobile GN2 lock screen (numeric PIN) recently. Twice, on random occasions, when I pressed the power (right-side edge) button to wake up the phone, before even touching the screen I immediately caught the "Try again in X seconds" in the middle of its countdown on the lock screen, just below the clock. The first time the countdown was at about 1s (almost done), and the second time it was at about 10s. There is no way myself or anyone else had physically tried and failed 5 times. Both times the phone was sitting near me face-up on a table, nothing else touching it, and nobody else around.
The first thing that came to mind was some kind of malware. But if an attacker is already "inside" so to speak, why would they want or need to brute-force the lock screen? And can the lock screen even be seen from "within"? I thought it was only relevant to physical access (on-screen or USB storage).
Does anyone know details about the lock screen mechanism to say what on earth this could be? Google search returns a few similar reports but only in dead-end threads. Even though my device is stock I figured this question may be above and beyond the usual users' forums, so I am hoping the expertise at XDA can help. Thanks in advance.
Here are more details that could be relevant:
- The device works fine otherwise.
- I saw the behavior happen randomly twice in the last 24 hours, and I had rebooted in between. Prior to that I had never seen it. I cannot recreate it at will.
- WiFi and GPS were set to off. The first time the phone was on AC charger (mains, not PC), the second time it was on battery.
- There have been no major changes (that I know of) to my phone. I have not even installed any new apps in the last few weeks.
- When I try failing the lock screen 5 times on purpose, I get the "Try again in X seconds" countdown under the clock AND a popup with OK button saying that I failed. In the behavior, there is no popup, just the "Try again" countdown.
- I do not notice any other suspicious activity like unfamiliar processes or unusual bandwidth usage, although I do not have the tools or know-how to examine individual packets or anything like that.

Bug?

Sometimes when i use the knock on feature several times in a short time period, it starts to ignore my taps.
When i try to unlock my phone again, it barely recognizes my touch events as follows it gets hard to unlock it.
Mostly i have to restart it.
Do you experience the same or a similiar problem?
Regards

Random Restart

So the phone is about three weeks long, and at random times it restarts. It's not like a normal restart it just prompts the Samsung logo, never go completely black and then it goes immediately to write pin screen, without showing the android boot video. I have the auto restart feature on device health off! What may be the problem if there is one, and has anyone else experience something similar???
Same here. First time after patching to april security fix. Just a few hours later a restart. Only needed the pin for the Phone, not the SIM card. Yesterday i installed may patch and a few hours later a random reboot. No reboot between this both.
No never random restarts or any crash here
