Lock screen gone

Usually after pressing the power button the pink lock screen from tmobile would show up. But today after pressing the button to unlock the phone theres no lock screen, it just goes straight to the homescreeen. I tried putting a password and it still doesnt bring up the lock screen. Has this happened to anyone else?

This is still an issue after a restart?

that would have been normal on CM7 if you disabled lock screen
but on TW... it's rather unusual, specially when we still have no root
can you try installing super user meanwhile you are at it?

Also, theres another problem. When I hold the power button the phone shuts off automatically instead of the menu asking you want to turn of the phone.

This definitely sounds like a faulty phone, I would return it. These options are normally present in a CM7 build like allgamer said.

I don't think that it is a faulty phone. Watch the review by Mobile Syrup and the lock screen on their phone is gone to.

mine is doing the same no lock screen and phone shuts off as soon as I hold the power button
Edit: just tried setting a lock screen with pin and nothing still hmmm

So weird. You could try contacting the guys over at Mobile Syrup that did the review.

So i just did a factory reset and everything is fine now.

No lock screen and when I click on power bottom it just shock down without the 3 choices (power off, airplane mode and silent)

If and when I get this phone you'll have about 9 lockscreens to choose from and a variety of power options (as well as a ton of other mods and hacks).
Just click on a few of the links in my sig.

Yes I can't wait

how do you do a factory reset?
What will a factory reset erase? Will i have to root again?
This is my problem, I have been using my sim card for like 6 years now and today it just stopped working in my phone..
So I took it out and put it back in , still doesnt work, and right after that happend I realized that my lock screen had ceased functioning which i read is a known issue.
So i lost all my contacts, i will go have to get a new sim tomorrow, still don't know if i should trade the phone is for a new one.

this problem had something to do with the *#0*# command, and and testing the camera while in that menu. i just reflashed the deodexed rom and it was fine.

I had this problem too. I had to do a factory reset to fix the problem.
Here's another thread discussing a potential cause of the issue: http://forum.xda-developers.com/showpost.php?p=18702063&postcount=12

There are programs out there to use until then. Right now I'm using Quick Boot and it seems to do the trick just fine.

I'm rooted and used Titanium Backup, and a few other "safe" apps. Then suddenly my screen lock dissapeared. Battery pulls would not restore it and neither would any settings fiddling. When I held the power button down two seconds, it would shut the phone off instead of the usual popup that gives you the option to power down.
The only way I was able to restore it was reset the phone to factory settings. Then I restored via a CW backup (wow CW is awesome)
Anyway is this a common thing? I can't imagine this happening to an iPhone. What could cause this--do I have to erase my phone next time this happens? What a PITA!!!

Did you try the numeric combo which gets you into the phone diagnostics? If so we discovered that the megacam test hoses the lockscreen for some reason.

[Q] My home button has stopped working completely (help!)

When I plugged out the charger this morning and turned off the wifi my phone suddenly crashed and started to reboot. I put the phone in my pocket and didn't think much about it seeing as this is a very common problem for a lot of people and it usually happens to me once or twice a week.
One hour or so later I pick up the phone to check something on the web and then press the home button to get me back to the home screen. Nothing happens. I press it again. Nothing happens. I have to then press the back button a bunch of times in order to get back to the homescreen...
After testing this a bit more I realize that this behavior doesn't go away, it's permanent, the button just doesn't work any more, which in itself is odd for a software button... Not only that but my lockscreen is gone as well even though it's set to "drag" in the settings and the "minimalistic text" widget on my homescreen sometimes have trouble loading up...
Rebooting the phone does not help.
Does anyone know how to fix this or even know why this has happened?
(ps. the phone is a swedish yakjuxw)

Nope, the device is stock.

I saw a dutch user on a dutch forum with the same issue. a Factory reset solved this for him... Not sure what caused it and it's a bummer if it happens to you but at least it worked for him.

Try using an app that puts your device in landscape mode and see if it works then ans when you switch back to portrait.

Thanks for the replies, but I did a factory reset and it solved the problem.

Had a similar issue when i just got the phone, systemui kept crashing and when i'd reboot none of the soft keys worked - had to wipe and factory reset as well!

Damn. This happened to me too, just spent forever getting stuff on my phone.
Well it looks like I'll be factory resetting...

Phone goes into random boot loops and vibrates? Any help

Okay so ive been running jmt v8 for about a week on my phone and everything was running great. Then yesterday morning my phone became very slow and unusable. Then i started getting the error message acore system has stopped working and the phone would randomly restart and then it would start vibrating then stop then vibrate again and so on. So i insalled a new rom and i stopped getting the core system has stopped error but i am still getting the random reboots. And the screen also wakes up by itself. Please any help or suggestions would be greatly appreciated.

I just had this fixed. There's something wrong with the power sensor, especially if it tries to boot the second you put the battery in without touching the power button.
Unfortunately you've been rooted now and because of the issues, you can't flash stock and reset the root count. So you can't sent to your carrier.
Fortunately, http://www.mobiletechvideos.com fixes EXACTLY this for $35 minus shipping it to them. I got my phone back today and it's just the way it was ROM wise and all my files are there and the issue is fixed.
This is a pretty common T989 issue.

I can boot into recovery but its tricky because I have to press the buttons perfect or it'll just reboot. I believe the problem is with the power button and ill probably get it replaced.

For anyone with key issues and need to get into recovery or download mode there are adb commands that do this. We get too comfortable with apps and forget about the manual way of achieving a lot of the same tasks that apps provide for us.
From a command prompt:
adb reboot recovery
adb reboot download

hey guys. after the ics update my phone started to lock up and its not rooted. now all of a sudden when i put the battery in it it vibrates once then starts to load and gets about half way and stops. then it turns off and just vibrates a few seconds and vibrates but the screen never shows anything. tryed using just a usb with the battery out and it skips the load screen and automatically starts vibrate looping. the power button seems stuck but i dont think i can fix it any ideas?

Hey everyone! I have a similar (but not quite the same) problem. Every now and then my phone "tells" me to restart it for maximum performance. Every time I restart or just turn on my phone it goes through the boot cycle, including a message that says "android is upgrading" (I got the ICS upgrade from Kies prior to rooting my phone). Then, all of a sudden, the phone doesn't work, and it starts the boot cycle all over again. This happens several times in a row, which for me is a safety issue because I'm not able to call Big Jon (my husband) to get me from the train late at night. Any fixes for that? Thanks.

Damn! Just found this thread...sounds like what my phone started doing today!!
I was clicking around on gmail, then back to home screen, the camera FLASHED all by itself without me doing anything, then started the boot loop thing. Clicking the power button only made it worse. Finally was able to get into recovery via TWRP...but that was weird too. I did a factory reset/wipe and was going to reinstall The Sith ROM that I was running, but it just rebooted and loaded up The Sith anyway and it should have been cleared. I then tried to restore back to Beastmade ROM, restore was very quick and said successful but it booted back to Sith.
Now the power button is hyper sensitive! All I have to do is brush the power button and it will light up the screen. Touch it too long and it will bring up the boot menu. I'm afraid to actually CLICK the button as it might go haywire again.
WTF is going on!? This all seems really odd that it's going down with some of these new ROMs being released. I wasn't even touching the power button when all this started. The weird clicks and flashes didn't sound good when it was all going on.
Has anyone tried flashing back to and OLD rom to see if it will fix it?

I took it to a repair shop, where I was told to send it to Samsung to do a heavy-duty root. The power button does need to be replaced because there is no spring when you push down on it. I have no idea if there's a root glitch. Has anyone sent their phone to Samsung? What happened? Are there alternatives?
Thank you!

It was amazing, I had the same problem but all i did was open up the back up undoing all the tiny screws and then took a can on compressed air and sprayed out the power button and its been working for more than a month now with the problem completely gone! try that first before sending to sammy.

Ok I am in the same boat. My device does not boot up, it will get to Samsung logo and restart half the time and the other half just vibrates every 2 seconds. I removed the battery while plugged in and it still vibrates. I took it apart and blew the power button with compressed air and nothing. Here is the funny thing if I bang the hell out of it, it almost boots up. Is there something that I can do less than sending it to Sammy ? If not I will sell it on craigslist for parts.

Same thing here. Only way to get it to power on is by hitting it, the harder the better it seems. After it turns on, touching the power button will make it go in to the restart loop 90% of the time. This sucks!
For me this started after I dropped my phone...with the case on and on carpet. I have also opened it up and sprayed with compressed air to no avail.

Hi Folks,
I had the same problem, the problem started when I dropped my fone on carpeted floor, here are symptoms
Fone restarts on its own, start the boot, inbetween the boot starts again, then, keeps vibrating every two seconds, you have to pull the battery out to stop it,
As soon as you put the battery back in, it restarts, again getting stuck, and then vibrating every two secods,
Here is what i did
- Cursed Samsung for making a sh***y phone - Didnt work
- Smacked my phone with whatever I could fine - Didnt work
- Opened all the screws up, took apart phone, pulled out the power button module (pcb), noticed power button was loose,put some glue into it, dried it, put it back, & ITS BEEN WORKING SINCE THEN ! It was a hardware fault, its not software !
Just my two cents, it worked in my case, I cannot guarantee if it will in your case too, try at your own risk !!

Same issue with SGH-M919. I was rooted and the rom I tried to use wouldn't work because the kernel caused some issues so I figured I would go back to stock. The device wouldn't go into recovery mode, so I flashed the stock rom via Odin. After the ROM loaded, the phone reset and I saw the Samsung screen then it rebooted and so on each time. It's not the power button as it works, has the spring feel to it and the phone would come one by itself if it was broken. So what can I do or am I in trouble?
Also, the phone will vibrate every 2 seconds

Sure, the power button will "work", but if it's constantly vibrating and rebooting, it's probably an issue with the power button. Do what it shows in the video I posted, and if you do it right it'll probably fix it. I gad to attempt it twice as it didn't fix it the first time, but it's been like 4 months and I haven't had an issue since.

Thank you but it was the kernel causing problems. Somehow, the new ROM messed up the partitions and subsequently required a full wipe including all data then I flashed the stock ROM back via Odin and it was fine. I rooted it again and flashed Bliss Pop 1.8 and I love that ROM. No issues at all. Thanks for the help. I'm slowly learning about ROMs and Linux etc.. I appreciate the help. Does anyone have any advice as to how I can learn more??? Where do I post to get past this 10 posts rule???

Wow I just realized that post was from a week ago and that was for my girls S4. We got rid of it anyway. My response was regarding my Sprint LG G3 which I am slowly mastering.

Same thing here but here i have a Lenovo …idk what to do

Takes 3 to 4 seconds to sleep after pressing sleep/wake button..

This started happening 4 or 5 days ago and I thought it would just fix itself but nothing yet.. When I press my sleep button most of the time it takes me to my lock screen before the screen going black but showing the clock and then it will cut off. Or sometimes it will just take 3 or 4 seconds before turning the screen off. It doesn't have any trouble waking up though. This afternoon I replied to a text message and then just left the conversation screen open and went to sleep the phone, it went to the lock screen but just stayed there and it was showing the time on the status bar, something it doesn't show when I'm on the lock screen. I pressed the button again and it was like the screen was off because it showed the normal screen. Does anyone know what the problem could be? I'm stock rooted, and it hadn't been doing this a week ago.. Thanks in advance

sounds like sleep lag...you might try to reboot it couple times

When I first noticed it happening I rebooted a few times and now I've rebooted almost once a day. Do I need to do multiple reboots one after the other?

I did the reboot and just left it, it doesn't lag every time I sleep it now, but it still does sometimes.. Haven't tried wiping it yet, would a complete wipe really help?

Yes, it would help. Could have a rouge app somewhere. It socks having to start over, but your not the only one considering it. May have to do so as well as I keep getting wake locks in stand by mode and unless I reset it, I lose mucho battery life.
