Galaxy S III Lock Screen On Android 4.1.2 Can Be Bypassed Easily
====Title====
Samsung S3 : Full Lock Screen Bypass
========Summary========
It is possible to bypass the lock screen on the S3 allowing an indivdual full access to the phones features
==============Steps to recreate==============
1) On the code entry screen press Emergency Call
2) Then press Emergency Contacts
3) Press the Home button once
4) Just after pressing the Home button press the power button quickly
5) If successful, pressing the power button again will
bring you to the S3's home screen
=====Notes=====
1) It can take quite a few attempts to get this working, sometimes this method works straight away, other times it can
take more than 20 attempts.
2) The method has been tested on 3 S3's
3) The method also seems to work better when the mobile has auto rotation on.

hi,
I have an issue with lock screen on my GT-7510 with stock 3.2. There is no lock screen when I lock the device. I can configure PIN or password and so on in settings but when I wake up the tab the lock screen is still missing.
I've tried factory reset with no effect.
can someone give me an advice how to solve this? I don't want to install any special app or custom rom...
Thanks
I have the same issue since my Gtab came back from being repaired by Samsung.
I have also tried a hard reset.
The only time I see any lock screen is at first start from hard reset.
Have you tried re flashing the stock ROM or maybe a custom one? Can't think of anything else that should work (or not)

I have the same issue with my GT-P7500, it has unlocked padlock on bootup screen, it has a correct IMEI on settings, but has NO SERIAL NUMBER (00000000000), I don't know why.
I tried several stock roms but the only one where lock screen works is with the last 3.1 for UK (PDA: P7500XWKHD CSC: P7500XEUKH3 PHONE: P7500XWKG1).
I have too a "Factory Mode" icon on home screen where I could write samsung codes (like "*#1234#" to see the rom version).
The problem: It doesn't matter the kind of lock you configure, after spending the correct time to lock it or pushing power button to lock it inmediately, there is no lock screen at all, and when you push power button again, it backs to the running program. At the same time, if you push the power button for 1.5~2 seconds, it just power down without the typical selection window (where you could activate silence and flight modes).
Other cons: I tried to install AOKP, and it show me a serial number.
Maybe with those details someone can help us.
in custom roms, like CM9, the lock sreen works, in stock ICS doesn't
I have purchased second hand galaxy S2 I9100.
I am experience LCD problem from the start. First w botton on horizontal arrangment not working.
I tried *#0*# test code for LCD and found one column from top to bottom not working.
Now LCD is behaving strange after i remove the screen protector. It goes to automatic selection in the middle of screen after some time of use e.g it automatically got selecting every thing which is on middle left of screen
I talked to some of my friends and they think it is a software issue.
I have tried flashing it with different ROMs using ODIN but no improvement results
It also go to downloading mode by only selecting volume down during power on.
Please help as I am not getting anything for solution
If that's happening with every rom you've tried (I presume you've gone back to stock firmware to test as well ?), then that's a hardware problem.
Home key Download mode
Yes I have also tried stock firmware of my model.
I have one more question. My Samsung galaxy S2 goes to download mode by pressing power and volume down button only e.g without pressing home key button. My home key button function properly at the android home.
I that also some issue with the hardware?
Try flashing the XWKL1 fw.. It pretty much fixed mine

If its still under warranty get the screen replaced. I did.
I.lost a whole collumn and wasn't too stressed about it but before long another collumn went. I expect more would have followed so better to get it replaced at their cost not ours.

Hi
I have an unlocked samsung galaxy s4 gi-i19505
Recently after i updated to 4.4.2 kitkat i started having problems. After the phone is not being used for a while, when i press the unlock button the unlock screen appears but the circle with the lock inside it is missing and the phone appears to loose touch i can't unlock the phone or pull down the notification panel. When i press the lock button again the screen goes black and the phone just freezes completely. It doesn't react to the unlock button any more or to the home screen button. I have to take out the battery and then everything is normal again until the phone is left unused for a while again.
I tried reinstalling the firmware again but it didn't help. I didn't factory reset the phone as I don't want to be setting it up again as it takes me a while. Does anyone have similar problems knows how to fix it ?
Thanks.
Hi all,
I have a Samsung Galaxy S3 GT-I9305T rooted and running Android 4.3 with Touchwizz.
The problem I am having is that the screen will not turn off and pressing the power button will not lock the phone. Holding the power button will bring up the device options menu (power off, restart etc) indicating that the button itself is still functioning.
Restarting the device will boot to the lock screen, however the screen still wont turn off and after unlocking the phone once, you can no longer lock the phone.
In the phones settings, under battery it shows that it doesn't even register the screen as being on or the phone being awake (see image) however the phone is still completely functional aside from the issues stated above.
This problem occurred after accidentally dialling emergency services from the lock screen while watching a video on my computer and absent mindedly spinning my phone in my fingers. As soon as I saw it was dialling I cancelled the call and took the battery out. When I started the phone I noticed the screen wouldn't turn off and the phone wouldn't lock.
Hoping I wont have to do a factory reset, if anyone has any ideas or suggestions, they'd be greatly appreciated.
Thanks
Have same problem with my Alcatel Onetouch Fierce 2. Fairly certain it's from this Kingroot in my case. However I don't know enough to prove this. I started using apps to lock the screen for me but they started not working as well.
Hi, I noticed that when I log into the S3 everything is fine but when I log into it as the 2nd user the screen goes blank right away. I have to press the power button to get it back and even then as soon as I enter the key code, a black screen comes up and then a moment later the normal screen appears.
Something similar happens when I turn on the S3 and simply pull down the screen to change user right away.
Is there any way to fix this?
