[Q] Where did my lockscreen go?!

When I was using my phone today, I noticed that a long press on the power button was shutting down the phone instead of bringing up the menu. Then, I realized that I had also lost my lock screen, which I really hadn't noticed because I don't use the pattern lock. Turns out, even if I enabled the pattern lock, password, or PIN, using the power button still took the phone straight into the home screen.
I don't know if it was an bug in a random app, malware, or what... I spent a lot of time searching for an answer on what might have caused it, but didn't find anything really helpful. I started deleting all my recent apps, but couldn't get the lock screen back, so I ended up restoring the phone to factory settings and starting from scratch.
The only reason I'm posting about it is that I'm not entirely sure what caused it... I'm debating the possibility that it could it could be a touchwiz bug. Anyone else ever run into this?

Yes, its a known bug. I just ran into the bug today and I refuse to do a factory reset to fix the issue since its just gonna happen again. Samsung should be able to fix it with a simple software update.

Does a reboot fix it?

No, so far the only way known to temporarily fix the issue is to do a master reset.

Ah, that would explain it... I was tearing out my hair trying to figure out what I had done. Funny thing is, I don't even *like* having a lock screen. I was just bothered by the fact something was wrong...
How did you find out that it's a known bug? I must have been phrasing my search poorly, because I couldn't find squat about the issue.
Still, whether I like the screen lock or not, I think this is a pretty decent security bug, considering it removes the ability to lock the phone...

I know because I seen it under "list of known issues". If you scroll down a few post you'll find it. The downside to not having a lockscreen is that if you receive a text message your phone will automatically unlock and you may accidentally dial someone if the phone is in your pocket.

FOR THOSE OF YOU WITH THE LOCKSCREEN ISSUE I ADVISE USING A 3RD PARTY LOCKSCREEN. I AM CURRENTLY USING "AGILE LOCKSCREEN" (WHICH CAN BE FOUND IN THE ANDROID MARKET). I AM USING THE PRO VERSION, BUT THE FREE ONE WILL DO THE JOB ALSO.
Sent from my SGH-T989 using xda premium

Mine's gone too.... Now that we have root I've a nandroid backup which I believe still had the lockscreen and will try restoring from that. If that doesn't work then I guess I'll do a master reset and restore from Titanium Backup. Hopefully Clockwork Recovery will survive the master reset...

I thought that was just me yesterday so I did a master reset

I was thinking the complete opposite. I installed ripple lock and that's when i started having the problem. Uninstalling didn't help. As soon as i uninstalled and a factory reset, haven't had any issues since.
Maybe just coincidence

No, its definitely a software bug. I don't advise doing a master reset because the issue will continue to happen.
Sent from my SGH-T989 using xda premium

For people having issues of making calls/etc. when the screen unlocks:
Just put the phone in your pocket with the screen facing AWAY from your body.

I had this happen immediately after using the *#0*# test screen, I'm blaming that

this sounds like a bug
it shouldn't need that, as in the lock screen shouldn't even dissapear
i'll suggest everyone experiencing this bug to report it directly to samsung, so they can fix it

Download gps test from the market. https://play.google.com/store/search?q=gps+test .. in the app press settings, clear agps, then update agps

Any luck with this? My phone also lost gps function. Im rooted and have been flashing the Jedi roms.

I didnt have any luck....

I guess it's off to the tmobile store after flashing back to stock.

Why not give some useful info at least. .. is it seeing sats but not connecting or nothing at all
Sent from my SGH-T889 using xda app-developers app

Mine is not seeing any satellites. When maps is open my location just jumps around based on cell tower data and eats battery. I'll have to find out how to put it back to stock, and maybe I'll get lucky and it'll work.

Odin'd back to stock. Didn't fix it, but I really didn't expect it to. A new device is coming tomorrow.

They are delivering it Thanksgiving day??

That's what the receipt says anyway.

No data connection after flashing a new ROM? Look here for fix.

I experienced the problem of no data connection after flashing a new rom on my Optimus G. The phone needs to be reprogrammed, updating your PRL and Profile will NOT help. You must dial ##72786# this will start the handsfree activation and your phone will reboot a few times. It may take a few seconds in between steps of the activation and it will seem like nothing is happening. Just be patient and wait for everything to complete. When it is finished your phone's data connection will be working properly.

Sent from my LG-LS970 using xda app-developers app

Some history,
I've been running Imperium and stockishv1 and v2 for a few days. I've made a couple backups along the way. About an hour ago I lost data. The phone works and makes calls, but my data is dead.
I've tried update profile and prl, and all I get is" Network error" I've tried this many times throughout all these steps.
I've restored backups, pre-Imperium and Stockishv1 with the same results.
I tried the procedure in this thread and still nothing.
Anybody have any other ideas? Would LGNPST restore the phones modem?

You guys need to read this. I am going to open an LGOG Issues thread but need to grab some food first.

I did, and responded in your ROM thread. Thanks
edit: Now all of a sudden data is working. BTW when my data wasn't working it still showed a flashing 3G. Sometimes. Both arrows on and off
edit 2: Also when data wasn't working, It kept wanting to roam.

saw the same thing on stock as well

More than likely your area no? Sprints been working on towers

Related:
I killed the connection optimizer while I was at work because I can't use work's wifi and listen to my icecast station I setup.
This killed my data connection and immediately put my phone into roaming. I rebooted like three times and finally my data came back (i also updated the PRL and the Profile, not sure which fixed it but something did)
From the things you guys speak of, I would guess the same issue is at hand.
ALSO: Stock rooted rom (non-deodex pure stock with bloatware frozen with titanium)

I am running CloudyG3 rom on Verizon LGG2 and after flash I have no data connection at all.

Try the G2 thread, I'm sure if you post in the exact same section over there you might have better results. General answer is that it is probably APN settings. Find an app, enter them, set it, and reboot (might not need to reboot).

[*gps fix] alternate gps fix]

**MUST BE ON STOCK TOUCHWIZ TO ACCESS DIALER MENU**
Thought I post this method on a different way to get GPS back from flashing from different ROMs. When I lost it, a fresh Odin install did not fix GPS. Basically nothing worked; clear maps data, Google. Servicesframework, tightening all my screws, gps fix it apps, etc.. Tried them all.
Then I came across a post that was in a att s3 thread started by "egyptshun"
So shout outs to him.
[QUOTE/]if you dont see your gps icon on status bar. there is problem on your gps chip.
becouse that was happend to me my I747. im more confused about it.
i try more things like rom change,, firmware upgrade,, orginal samsung updates,, etc,, no more fix
after i go to the samsung service mode *#197328640#
then go to mainmenu>UMTS>Common>NV REBUILD>NV REBUILD>finish and dont exit menu
wait 30 sec
long press power button and select restart..
thats all
now check your GPS from gps software...
if this is fix your problem dont forget to thanks....[/QUOTE]
so yeah there it is. This method worked lovely for me. I was about to do a warranty exchange till I seen this.. Saved me the hassle

Thanks for the info

This worked great, my gps issues started when I flashed to a 4.2.2 rom and went back to stock 4.1.1. After searching endlessly this is the easiest fix there is out there.

Fast and easy
WOW. This worked so fast and easy! GPS Signal locked on instantly after the reboot and turning on GPS. I lost my GPS going from Cyanogenmod 10.1 to Darthstalker S3 edition Version XI.

Yeah I was so relieved when I did this.. It was such a head ache. Been seeing a lot of people going thru the same thing.
So maybe this could get stickied or something

This should definitely be stickied

I am on LiquidSmooth RC2, when I entered *#197328640# on phone dial pad, nothing happen.

Only works on TouchWiz.

This worked amazingly well! This does need to be stickied like someone mentioned earlier.

Restore a touch wiz nandroid, if u have one. Then use the dialer code. It'll be faster that way, you won't have to Odin, and use a pc

Nice find, will try this later after I back up.
Might want to state in the OP that the Samsung code only works on the Touchwiz dialer just to make it clear. :thumbup:

Just finished restoring and it worked out amazingly! I flashed Wicked and typed in the code, rebooted, turned on GPS and tested on both Google Maps and Navigation, Restored back up, tested again on both apps and it was spot on. Thanks again

WOW! My GPX had broke for the second time and I was about to cry thinking about Odin lmao.
worked perfectly! GREAT FIND!

Since this fix seems to be pretty solid (and becoming a prevalent issue), I've included it in my signature.

This thread makes me a lot less wary about flashing something like Liquidsmooth, when Wicked remains my daily. I'd need to switch back and forth. Good to see there seems to be a practical way of dealing with possible GPS loss, without jumping through hoops to get it back.

GPS issues

Hi! I have 3month old Tmobile Galaxy S4. Everything is great expect for GPS. My GPS wont lock on. When GPS refuse to lock on. I use an app called GPS Status & Toolbox. I use GPS Status to reset my GPS. Then I go back to Google Maps and GPS will lock on. After 3 or few days, GPS will stop working. I go to back to GPS STATUS app to reset the GPS. Then GPS will work again. Then repeat.
Is that software issue or hardware issue? I hate it when GPS stop working and I have to reset it.
And no, I don't have Yahoo Weather. Hope you have any tips or ideas. Thanks

I don't know for sure...but this screams "software issue" to me. Are you rooted?
If so I would suggest trying a different rom to see if the problem goes away
Sent from my SGH-M919 using xda app-developers app

Sounds like a time issue. GPS cannot function correctly without correct time. Maybe you have "network-update time and date" disabled? You maybe can also try a diff radio? Or reflash your existing one.

No. Its stock and never rooted. I was thinking of flashing CM 10.1 RC2.
I also check the time setting. Automatic date and time and Automatic time zone are checked.
