Can't change pin code on Samsung Galaxy S2 - Galaxy S II Q&A, Help & Troubleshooting

Hello! I'm having a pretty annoying issue with my phone that I want sorted so I'll get straight to the point:
My friend gave me my first ever smartphone not too long ago (an old samsung galaxy s2) but I just can't change the pin code on it. It just won't save the changes I make. I can navigate to the options to change it, input a new pin code, lock my phone again to enter the new code only to find that it hasn't changed at all. Neither can I change it to a pattern lock or any other sort of security lock. It just stays stuck at the old pin code.
I've tried reverting it to factory default numerous times but it doesn't do anything.
Since it's my first smartphone, my experience with smartphones is pretty basic and I need this sorted out asap!
So what's going on with this phone? Why can't I change anything? Help!:crying:

[Q]Forgot pincode/ password

I kinda feel that this isn't completely relevant but I'm kind off not doing so good. The other night I changed my phone lock from pattern to pin code (done on the verge of sleeping) and I forgot my pin code. Is there anyway to reset my galaxy player without by passing the lock or something. Its not yet rooted and its a galaxy player 5.0. Any help would be greatly appreciated.
if u mess up on pin more than 5 times, there should be a forgot your password option on the bottom
Did you have android debugging checked in settings? If you did, you can use adb to bypass the lock
I accidentally my Galaxy Player

[Q] [S][Security] How to replace Pin Unlock with normal unlock?

Hello, i think it's not becoming clear from the title, but i don't know how exactly to name it. I have a corporate email set on my Xperia S. Since the email is corporate, i had to set Pin Unlock, which is something i don't like at all - especially when i'm driving. Is there a way to trick the security settings or the android to think that i'm using pin code unlock, but instead to use the normal unlock screen? The only possible unlock solutions which i have now (having in mind that the device security is managed by the exchange service) are pin or password unlock.

Did I get that right? You want Android to think you have a PIN, but don't want to enter the code?
You could make a delay until lock, so if your phone switched off, and you turned it on again after a minute, it's not locked yet.
Actually it's almost as you say - i want to be able to lock it and use the normal unlock slide instead of entering a pin, without having to remove the device security setting - basically trick the phone that a pin unlock is used. I still want to be able to lock the phone, since otherwise it's not sleeping properly and is reducing even more the already short battery life.

I don't think it's possible.

[Q] Samsung Galaxy Centura Lock Screen

My step daughter is a MAJOR kleptomaniac. She loves to steal phones and ipods from friends and family, idk why. Anyway, I had just rooted my phone and ran out of time (prepaid- tracfone) and put it away. She still found it and put a text lock on it, and won't give it to me. I DO NOT want to do a hard reset.
Help me bypass the lock screen or reset the password somehow, please.
The forgot password pop up does not pop up after trying many times with random letters.
I emailed the phone company days ago, and they have still not replied.
I have searched all over for a solution here and google.
I have all the SDK tools if you have a method that requires the tools or command line.
Thanks.

Can't disable screen lock on samsung-stang5litre edition 5.0 password

Hello,
I'm pretty good at computers but when it comes to phones I'm a dummy. I set a password in my Galaxy S5 running samsung-stang5litre edition 5.0 I just bought this phone and it had this ROM installed. I looked up instructions online for this phone to remove it (settings are not working or showing for this ROM) for this phone model and there are no instructions for this ROM. How do I remove the password or do I have to reset this phone ? If I reset the phone will it still ask for the password ? The person who sold me this phone also changed how this ROM looks and deleted almost every program out of it before I bought it. Please help me.
Found help
Since no one answered back I contacted someone to help me. I'd have never figured this out by myself. I'm so glad for his help. This is what worked.
What you have to do to remove that pin, go to Settings>Lock Screen> Screen Lock> Pattern> Setup any pattern, then setup Pin Code with it after you setup the Pattern. (You already have a Pin set in, just use it). It will ask you to type it in twice.
Now Power Off and Power On the phone it will ask for the pattern, do 5 to 6 wrong patterns, it might time you out for 30 seconds after that, on the bottom right of the phone it will say "use your Pin Code", hit that button, type in the Pin which you already setup while you were setting up your pattern, then use that Pin Code to unlock the phone. Now Power Off and Power On the phone, you shouldn't have any pin or pattern code to unlock anymore.
This worked for me.
