Yesterday my phone freaked out and the lock screen turned in to a white screen with no input box only an emergency call button, I was using knock. I ended up clearing the phone out and started from scratch so I wiped data, but now when I select knock and lock the phone, it quickly prompts the type in your pin then opens.
Anyone seen anything like this?
Edit
Actually any lock screen I select does what I described above other than swipe

Did someone try to enter your phone multiple times? Maybe this is how the phone locks them (or you...) out. After a number of unsuccessful attempts, the phone will prompt you for the unlock pin you set as a failsafe.

Well first I noticed the phone wasnt really locking, it would flash to the back up pin lock then flash away, and it did that many times before the screen just went white. I rebooted, cleared cache, I was unable to adb to it. I ended up clearing everything and starting from scratch.
Its really odd, only the swipe lockscreen works.

I was typing out a text today (normal mode, not landscape) and out of nowhere the screen faded out and went to the lock screen. What was even more peculiar was that I had no option to unlock the phone; when I tried to swipe my finger where the unlock button should be, the screen dimmed and the letters for the time turned blue while the other stuff (signal, battery, etc) disappeared from the screen.
When I hit the home button I was able to get back into the phone, however it faded back to whatever mock lock screen was there before. The second time I hit the home button it let me get back to the text and finish it.
Has anyone else had a similar issue? I've unlocked my bootloader, rooted, and have flashed several different radios (currently on ugkl1, stock was xxkk6).

I have not had that happen...I am unlocked, rooted, and running a custom rom and kernel. The only thing i did not switch is the radio...So may be what is causing it?
I reset the radio to XXKK6 just for safe measure.
Anyone else seen this issue?
I had weird problems with typing messages in Handcent with weird lag and even force closes on 4.0.2. Have not had these problems on 4.0.4.
So, as it turns out, this problem was cause by my own stupidity...
What was happening as that, in a very small amount of time, my thumb hit the task manager button, and the Clock app was the one that was right under my thumb, which was subsequently selected. For some reason, if you start Clock and try to swipe your finger, the screen dims.
So, total false alarm. Move along, nothing to see here.
I just received my Z1C and I've been having lots of touch screen problems.
When I get to the unlock screen, a lot of times nothing will register on the touch screen. I have to push the power button to turn the screen on and off to get the touch screen to register, and a lot of the time I have to turn the screen on and off more than once to get it to work.
Another issue I'm having is in the settings menu. The top portion of the screen doesn't register any touches. For example, when I tap on the Wifi settings, nothing happens. I have to pull down the screen like half a centimeter, then tapping Wifi will work. This is so frustrating...
Is there any way to fix this without rooting, unlocking bootloaders, or installing a custom rom?

already tried a hard reset ?
Yes. I've done a factory reset, and nothing has changed. Nothing registers on the unlock screen when I touch it. I have to turn the screen on and off multiple times to get it to work.
I am using the free screen protector that came with the phone. I doubt that's the issue though.
This can't be normal. I'm thinking I just got a lemon...

if youre done a factory reset and the problem persist im pretty much sure its a hardware problem...
anyway, go to about -> diagnostic and make the touchscreen test.
any issues there?
if i were you, i would reinstall the firmware using SUS to be 100% sure its HW problem.
Already you try a hard reset. I think it is your harware problem. If you have a warranty you can go customer care. I am sure they solve your problems.
not working at all
Hi guys, my diplay is also down - broken - and i have a gesture lock on. I can not unlock the screen. How can I perform a hard reset without touching a display? I was searching whole internet for two days and nothing helped.
If I connect phone to the PC, it must be unlocked.
I need some files from internal storage :/
HELP!!!
This is a really weird problem with my non-rooted D850 on an MVNO (H20 Wireless). I have had the phone for several months and other that a battery issue, I'm super happy with it.
I had been using the knock code to lock the phone and my home as a safe place. Never had a problem with the knock code.
Two nights ago, in an attempt to appease a suspicious wife, I decided to change it to a pattern so she can get in, then I got a pair and decided to change it back to the old knock code. I then noticed that the knock, and swipe where grayed out and so did the research and cleared the credentials to bring the knock code option back. Now the knock code does not match and I can't change it to anything else.
When I reboot the phone the knock code request comes up. I start to do the knock code and it turns off the screen at the second "knock". I double tap toward the top of the screen to avoid the knock code area, the screen turns on and it's asking for the knock code, wich doesn't match, but I start the one I knew again and it turns the screen off again and the 2nd knock. After five times the phone asks for the back up pin and I'm in, and the phone immediately asks to change the lock screen. I change the screen lock it to a pattern as the knock and swipe are grayed out again.
I receive confirmation of the lock screen has been changed, but NOPE!!! NOT CHANGED!!!
It's still asking for the knock code, that doesn't match, at reboot, or when I try to change the lock screen. To add insult to injury the phone won't lock, even if I leave it sit for an hour (time out is 2 min and I'm not at my safe place)
Any thoughts other than a factory reset?
Not having any luck with research. I would love someone's input.
Beuller? Beuller? Beuller?
Now I find that I can't reset my phone b/c of the knock code that doesn't match
Factory Reset
You could try powering off the phone, holding the volume down and power button. When the LG logo appears, quickly release the power and volume button and after that hold them again, you will see a white screen with an option to reset the phone. Don´t know if this works with the knock-code, let me know!

I ended up doing a factory reset a couple weeks ago. I couldn't find ANY support information about this. The phone had the knock code locked in, and since it "magically" changed (or fat-fingered when trying to change originally) it rejected the only knock code I ever used. The LG volume/power reset is difficult for me (as are screenshots) to perform as I have fairly large hands and the buttons are right next to eachother.
Either-way, i ended up resetting the phone and now only use a PIN or pattern to lock it. Pitty many apps seem to not like the knock code as a secure locking method.
my oneplus 3 (rooted) is not accepting my swipe pattern and does not give me the option to enter a pin code after a forgotten swipe pattern. i called oneplus but the person i spoke to said the only option was to wipe the phone. she would not allow me to talk directly to anyone with any technical expertise.
when i power on the phone everything seems normal until i get to the swipe pattern screen. first ,the bootloader screen (i think, the screen where you either press the start button to start the phone, or use the volume buttons to select options like poweroff/restart/recovery etc) shows up and then the oneplus logo comes up with the 'powered by android' at the bottom. then it shows the two white dots orbiting the red circle and then the screen to enter the swipe pattern appears with 'to start android, draw your pattern' at the top. i have made a few failed attempts, but it is now counting down, saying you have 6 attempts before the phone is wiped.
about two weeks ago i began having an issue that occurred maybe 2 or 3 times since. i would pull my phone out of my pocket and it would be powered off. after i turned it on, the initial swipe pattern would not be accepted, but the second swipe was always accepted.
i have tried entering recovery mode (teamwin), but the swipe pattern fails here also.
is there any way to get the phone started without losing my data?

Don't think you can do anything. Haven't encountered this what did you do with your phone? Are you on the latest TWRP? Latest OOS?

i had not changed anything on the phone recently. the swipe pattern has been the same since i got the phone over 2 years ago. i believe i was on the latest twrp, and i had a notification for about a week or two that there was an update available, but did not get around to downloading and installing it yet.
Okay, so suddenly when I use my finger print it is asking for my PIN. When I input the PIN the screen turns black and my lock screen simply reappears. So I use my PIN or finger print again and it turns black again and brings me back to my lock screen again.
Now and again previously to today after using my fingerprint it would ask me for my PIN occasionally That's not unusual. This time however it just goes black and kicks me back to my lockscreen. I proceed to repeat the process and same issue.
I can't access my phone via PC either since I can't change the settings for file transfer on the lock screen. Just wants my credentials again.
I forget which rom I am on since I can't get into download mode or recovery.
Any ideas? This may sound like a dumb question, but since this is never happened before, is there another way to reboot my phone without having the ability to access my reboot options? Holding down on power does nothing.
Okay, so on a hunch I long pressed the power button for two minutes. It ended up rebooting and when it loaded some of my app icons were grayed out and I got the message "App Not Installed" when I tried to open any of the grayed apps up. I rebooted again and everything is back to normal.
Also, when I plugged my phone back into my PC I got the authorization prompt again to allow connections and it fixed my device not showing in ADB. Does this key expire sometimes?
Just wanted to let everyone know the issue seems to be fixed. Well, for now.
