Problem: Raphael doesn't ask for SIM PIN when turned on

Hello,
my problem is that when I soft reset my device then the SIM PIN screen comes up for a second and then disappears and the phone starts loading TouchFLO. After that it also doesn't come up. I have to open Phone to get to the PIN screen and log me onto network.
Any idea how to fix it so that the phone asks me PIN code every time it boots up?
Thanks.

I've got the same problem.
But it's much easier to turn the phone on. Just press the "green" button on your phone and the screen where to fill in the PIN appears.
I know, it's not a real help, but it makes life more comfortable
Hope I could help you...

Update your rom to another one, some of the original 6.5 builds did this, but most roms have been fixed now.

[Q] Almost giving up on android phone....

Hi there,
Is there anything I can do for a T-Mobile ZTE V768 gingerbread phone that doesn't enter recovery mode(it freezes) or download mode(it reboots),
and can't start because it has a pattern and it is locked for T-Mobile? The phone was sent to a friend here in Honduras from the USA. I have really tried to help this guy but have not met my goal yet.... Any ideas would be totally useful....
Regards and thanks in advance,

Hey dude hope this will help
A couple of weeks ago, the iPhone world discovered an exploit (not fixed) that allowed anyone to bypass the lockscreen and access the phone, messages, and even pictures.
Well, the bug has been caught in the GS3 world now, too. A few days ago, mobile enthusiast Terence Eden discovered a flaw that also allowed limited access to certain features of your Samsung Galaxy S3, and only in very certain circumstances. And it works no matter what protection you have enabled...Pattern Lock, PIN, Password, or Face Unlock.
Steps to Exploit #1
Lock your phone and turn the screen back on.
Go to Emergency Call.
Select the Emergency Contact icon on the bottom left.
When in the Emergency Contact screen, hit the Home button.
You will see a flash of your Home Screen (no matter what launcher you are using).
In that second when the Home Screen flashes, you can select an app/widget to execute.
The limitations with this exploit are that almost anything you select will run in the background, and you will be back at the lock screen. Where this exploit can be effective is if, let's say, you have a Direct Dial widget on your homescreen. In this case, someone can hit this widget, and the call will go through.
While this is something that should be fixed, it doesn't actually allow you to do much, so really, it's not all that scary. Unfortunately, the fun doesn't end there.
Yesterday, Sean McMillan of Full Disclosure opened up the initial exploit and discovered something much scarier. If successful, not only will this exploit open up the full contents and capabilities of your S3, but it will disable the lock screen completely until the phone is rebooted.
Steps to Exploit #2
Lock your phone and turn the screen back on.
Go to Emergency Call.
Select the Emergency Contact icon on the bottom left.
When in the Emergency Contact screen, hit the Home button.
Immediately after hitting Home, press the Power button.
If you did this correctly, the next time you press Power, your device will go directly to your homescreen.
This is obviously not good. Sean does note that you may need to do this multiple times to get it to work. Also, it doesn't matter what launcher you are using, or whether you are using a lockscreen replacement or not.
In the interest of full disclosure, I tried about 30 times, both with my rooted/modded phone, and with a bone-dry stock phone, and I couldn't replicate it.
But, just because I couldn't do it, doesn't mean it isn't real and dangerous. At this point, there has not been any word out of Samsung regarding this exploit, but I imagine a response and a patch will be on their way shortly.

Lock screen pattern changed on its own, possible bug

I unlocked my phone normally several times today using my pattern. Five minutes after I had unlocked it, I picked it back up and drew my pattern and it said it was incorrect. I tried several more times with no change. I was able to unlock the phone using my fingerprint, but I have no idea how my pattern changed without my permission. If my phone dies or restarts for any reason, I will need the pattern to unlock it, as you can't use fingerprint on start up. (I've had the same unlock pattern since my last phone, so I'm sure I am putting it in correctly.)
Has anyone else encountered this bug? Is there any way to create a new pattern using my fingerprint? Finally, how should I go about reporting this to Samsung?
Thanks.

Yes!
Same thing happened to me... S7 working great for first few days when suddenly it didn't accept my unlock pattern. I've been using the same pattern for awhile and unlocked the phone a few times that morning. After a few reboots it finally accepted my pattern again. Immediately disabled it and now using pin instead.

Did you just restart again and again until it worked? If it worked for you I might try it instead of the factory reset.

I've had lock screen issues with my LG V10, but not quite like yours. I use a pattern, not a password or fingerprint. Sometimes the screen is locked and I fail the pattern and the phone gets unlocked anyway. Usually, this is associated with having first touched a notification with the screen locked. What happens after the pattern fails (trace shows in red), is that the screen appears as it does when it's not locked and I just swipe and I'm in the application whose notification I touched. The LG V10 has a fingerprint reader on the power button, but I haven't programmed it since I heard it's not that great. This is a major security issue in my opinion, and I haven't read any other posts anywhere about it. So I don't know if it's specific to LG, the V10 or Marshmallow (it started with Marshmallow).
I can start a new thread if you believe our lock screen problems are unrelated (enough). Just let me know.

Same thing happened to me. I'm THE ONLY one to ever use my phone and I went to open it and it was saying my pattern was invalid. I was able to use the thumb print pattern still though. However when I went to change the pattern in my settings I entered what used to be my pattern and it locked me out of my phone for an hour. I don't know how to change it.

Saw you had the same issue, so wanted to let you know. I restarted the phone and the old pattern started working again. Another person with this issue said that they had to restart several times, but it did work. So I'd give that a try, worked for me. Good luck!

It just happed to me. I restarted it and it accepted my pattern. I now have it set with pin instead.

Had the same issue as well! Samsung Galaxy S7, suddenly stopped recognizing my screen unlock pattern. Same solution as well; Restarted my phone and the problem went away.

Is there a way to disable the pattern feature if you are able to navigate the phone? Got locked out of Marshmallow on my MOTO G 3rd gen. phone after a pattern change; I was surprisingly able to just reboot into an unlocked phone. I've turned on adb debug access while I still have the opportunity.

I just had that issue. I was able to unlock with the pin, and reset the pattern and it now works again but it was freaky.

Same happened here. This morning the lock pattern on my S7 edge is forgotten by the phone.. Reboot doesn't help.

have the same problem today. i didn't change my pattern and it happened again. before i was using a PIN and I ended up factory reset and by this time I wouldn't want to do the reset factory settings as the last option.

The pin was also randomly stop working, I have mine set to pin and it did the same thing.

Me too!!!! Wtf!!
Mine has locked as well and I swipe the wrong pattern until it gives me the option to put in the back up pin but when I go to correct the swipe it wont let me in. I have tried everything all of you have suggested except the factory reset, I just can't believe that Samsung hasn't put out a fix for this yet.

Here is how you fix it
Method 1. Use 'Find My Mobile' feature on Samsung Phone
All Samsung devices come with "Find My Mobile" feature. In order to bypass Samsung lock screen pattern, PIN, password and fingerprint, you can just follow the below steps to get it done.
• First of all, set up your Samsung account and log in.
• Click "Lock My Screen" button.
• Enter new PIN in the first field
• Click "Lock" button at the bottom
• Within few minutes, it will change lock screen password to the PIN so that you can unlock your device.
tell me it work ??

Just an update to help out someone who might be going through this. This recently happened to me on my s6 edge.
Like the above comment suggests, go to "Find My Mobile". Once signed in, select the "UNLOCK MY DEVICE" option , (selecting the "Lock My Screen" option does not allow you to change the lock screen type afterwards).
Selecting Unlock my device will immediately unlock the phone and erase any lock screen patterns, fingerprints or pins that you might not remember, thus allowing you to set them up again!
Hope this helps!!

Also, one more thing. Doing the above ^ seemed to have solved a problem I was having with "Smart Lock" not working. So just as an FYI, going through that process might help you with that.

This just happend to my gf's s4 also she sent a text and then went to reply again a few moments later and her pin was invalid and it locked her out of her phone for 30 seconds, she just had to restart it once and it worked with the old pin again.

same issues here, pattern just stopped working. im positive im using the correct pattern.
i can login with my pin, but i cant reset the pattern as it keeps asking for the current pattern.
how can i reset the pattern or change to pin / fingerprint?
ive restartted 2x and trying a 3rd now....

> Use 'Find My Mobile' feature on Samsung Phone
No this didn't work. It still requires my pattern, and tells me I'm doing it wrong...
It DID let me into the phone, which was nice. But the pattern problem persists...
...Update: I restarted the phone, and it came up and accepted my pattern.

This just happened to me on my phone and my tablet. I wound up having to do a factory reset on both! Way to go Samsung. These are the last Samsung devices I'll ever buy.

Black screen but phone boots, Z3.

Hello All,
Basically what happened is this:
I got phone D6603 with "Vodafone protect" lock on and owner gave me a possible code for phone. I replaced screen and then found that lock requires only numeric pin, not what I was given. So, he then reset pin and deactivated lock, but I still had it on no matter what. So, I tried to flash new firmware into it for same phone and got it done, but now phone screen stays black all the time with only backlight on. Phone seemingly loads something (probably the new phone welcome screen after flash), which I cannot see, but when connected to computer from fastboot or something then all system files are visible.
When I boot phone from off position, it boots to a point where I can use side button to switch on and off the screen but touch does not respond because nowhere it reacts to touch or maybe I do not know where and what to click on screen.
What could be the likely solution? I do not think that phone is bricked, but something is wrong with system as it does not light up the screen properly. I tired flashing 2 times successfully with same result.
Any advice would e appreciated.

Hi, can this thread be deleted because I am getting phone swapped and thread no longer relevant? Thanks.

[SOLVED] Half of the screen flickers black between unlock and home screen

Couldn't find any similar topic except in forums for s10+, OnePlus and other phones. Sorry if I missed anything.
As in the subject, after unlocking, approximately half of the screen flickers black and goes to the home screen. It takes less than a second. Always top half, bottom half shows home screen right after unlock. This does not happen on each unlock, but also, there is no pattern - it can be after 5 or 30 unlocks, it can be after 5 minutes or 10 hours of not using the phone. It started mid-July and not only annoys but is starting to worry me. Solutions from other threads didn't help. For example:
Fingerprint sensor problem - I don't use it, I have pin lock.
Samsung Pay issue - I don't even have it available, so, don't use it either .
Animations - setting them off did not help.
I cannot guess anymore what would be the cause, if it's some app which wakes up after unlock or what else. The only thing I've changed (except updating apps) was adding another sim card, but my tiny little brain cannot find connection. I didn't test removing it as I need this sim active and don't have backup phone right now. Also, I would really like to avoid resetting the phone...
Did you experienced anything similar?
Thanks a lot for any help or suggestion.

are using Samsung or some third party launcher. Did you wipe cache? Latest firmware updates?

Yes, I did both, firmware update and cache wiping, no change. I'm using stock launcher.

did you try in safe mode to exclude some app causing it

Yes, I tried safe mode without success.

i would take it to Samsung repair centre if pos

Thanks for trying and all the steps. There's nothing like that where I live, neither any advisory place except for hotline. I can drop it at their service but will need to wipe it down before, which I keep as the last resort. I'll keep waiting for another firmware update and if nothing changes then I'm willing to do the hard reset. I just hope it's not a symptom of some virus - I'm trying to be most careful, scanning device periodically, didn't root, so I naively count on being safe...

i don't think it's virus. fingers crossed it's just software issue

hi again, just to let you know, I think I know what was causing this flickering and now I feel silly . Home screen rotation. I had this option turned on, and it's possible that sometimes, when I put my phone on the table, home screen rotates to horizontal position. Of course it locks after few seconds. I've noticed it completely accidentally, because one time, when screen flickered black there was slow-motion rotation animation in the background (which I've never seen before). That's why flickering was completely random to me, not connected to any type of notification whatsoever. Well, it's not, it has a pattern . I've checked it plenty of times and each time I lock my phone with home screen in horizontal view, but unlock in vertical, half of the screen is flickering black. That's it, at least I believe it must be this, because it happens each time and never when I lock my screen in vertical position.
Once again thanks for all the help!
