Lockscreen bug? Doesn't seem to be ROM specific. - Nexus 7 Q&A, Help & Troubleshooting

I have tried over 4 different ROM's trying to get this...bug to stop. A lot of the time when I try to unlock my device, each time I slide to unlock, my screen goes black...and I have to keep unlocking my screen to get it to go to my home screen. This is so frustrating, it can take 20+ unlock attempts to get it to actually unlock. Is anyone else having this issue or does anybody know how I can fix this?

Never seen this... I use a pattern lock, but never seen anything like this on any Android device except once when my Nexus One was swamped with logging from a crappy app on the market, and it just simply wasn't receiving input.

I'm going to try wiping my device out completely and going back to stock to see if that solves it... sigh.

Wiped all data, flashed to stock....nothing. I also tried other lock screen styles like PIN and Password... same thing. Is this something I would be able to RMA for? Do I go through Gamestop or Asus for it?

I've been having this issue as well. I did a little digging, and it looks like it's usually due to the case. For some people, it's static buildup from the case. For me, it's because I have a case with a magnetic closure that turns off the screen when I close it. The magnet is pretty strong, so when I fold the front cover around the back of my Nexus 7, it can still turn off the screen immediately after I unlock it.
Try fiddling with your case when you have this issue. It might resolve the problem.

Locked

Sitting on a train. Started the phone. Can't unlock it. The screen is dead so I can't enter pin. When I push back I come to the locked screen. Can't move. Haven't got pattern on. Wtf. :-(
Ps. I managed right now to unlock it. This is true. I pushed Start button. Then audio down button. Then I could sweep away the "glass".
Now I'm stucked again. And the audiodown trick won't work. I'm going crazy. For real. Any suggestions?
Have you tried removing the battery, it has been known to work with some android handsets

Tried that many times.
Maybe it's the Launcher.
I will try the touchwiz for a while and see if thats helps.
Used the standard launcher. This morning the phone was locked again. Haid to remove battery. Am I doing something wrong?
Start+swipe is all I trying to do.
GONNA RESET THE WHOLE PHONE.
But thats not good for my work-settings and program :-((

Phone worked when I left home. It was charging. Now it's impossible to unlock it again.
I removed the battery 5 times or so. Now it says: Enter Pin. But I can't the screen is dead. When I use the back button I get the background picture and the text who says: Phone Locked. But I can't sweep away the "glassscreen"...
I would (almost) be glad if someone else had this and we could figure out what is failing...
PS. This is my last writing in this matter, until someone else gets it. Now I removed the battery and strted the phone for maybe the 10th time since I started.
This time I didn't touch the phone for 1 minute maybe. And it works. I could enter the pin directly without unlock.
I'm much more near to start cry than laugh right now ;-)

Can't unlock - just relocks and goes black

My rooted 32GB has just started doing this (2nd time this has occurred now). When I try to unlock, it just makes a click sound and relocks and blacks the screen. The first time resolved itself. Not sure if a reboot will help (probably so), but wondering if anyone has seen this or has any suggestions.

Is there any magnet near the N7? (if you have case, maybe the it is not working to well, most of the case is not prepared for daily use )

Does the screen turn on and everything looks fine, but there is no touch response at all? Do the hard buttons prompt the menu's like power down and volume control but there is absolutely no touch input? I am asking these questions because if it is doing this you are having the same issue as me, I had been working on this issue for a solid month with absolutely no luck and the issue kept getting more frequent.I have re-flashed stock Google images both 4.1 and 4.2 with absolutely no luck. After the clean installs I did not root it I left the it completely stock and the issue is still there, also I thought it may have been my Poetic magnet case, well i took it out of the case and it still does it. I even removed my $20.00 dollar Steinheil Ultra Crystal Screen Protector thinking that may have something to do with it but that's not the issue. After every reboot it will work fine, so I was completely frustrated and could not find that many people on line with this issue. I finally had to send mine back to ASUS and they stated it was a screen assembly issue and they could replicate the problem, well I got it back last week and five minutes after booting it up the issue is still there so needless to say I have to RMA it again. What really bugs me is the Nexus 7 worked fine for two months not one problem then, I left it in a cabinet for 2 days without touching it and that's when the issue started and it has just gotten worse.
I apologize for the long story if this is not your issue but I just wanted to save you a lot of hassle if it is.
My issue isn't as complicated, fortunately for me. The screen is black (even though cover, with magnet, is open). I hit the power button once to get the screen to light up and slide the unlock. It looks normal but only flashes for an instant, then makes the click and the screen goes black again.
It self resolved again, so I actually am suspecting that it could be that when the case is folder over, the magnet may possibly be causing this. So thanks for that suggestion. Next time it happens I'll be looking specifically for that to see if I can narrow it down.

[Q] momentarily unresponsive touch screen

Hi guys
I have moved from iPhone to a note 4 and loving it!
I was just wondering if anyone has found the touch screen occasionally doesn't respond to their touch and you have to touch it again. On the iPhone it only ever missed a touch if my finger was in the wrong place, but it never happened on the keyboard. Every so often maybe 5/6 times a day I touch a key on the keyboard and nothing happens, when I try again it's fine. I can't reproduce it, because when I tap anywhere on the keyboard something gets pressed. I was just wondering if this was normal?
Hope you are enjoying your phones!!
Anyone?
It's most likely cause your palm is on the phone. One of the downsides of a slim bezel on a big phone. Also keep in mind if your spen is on the screen, your fingers won't work. A case might help.
I thought about another part of my hand touching the screen, however with half my hand layed across my keyboard I can still type with the other hand. Thanks for the response
I Pele tried factory resetting today and not installed any apps, but it is still happening
I rang Samsung this morning and they advised I return I to the store and get an exchange. Luckily my local store got its first batch of note 4s in this morning and they swapped it out. I restored it all firmware updates put on it and now works fine! The only thing I haven't installed is a Google play system update thing. I was wondering if that was the cause x
Similar issues
I've had similar issues (in fact, that's what brought me here in the first place). Initially, I was able to tap on the screen in the text box and then continue typing (I use Swype). However, now my messaging app (default Messages) just freezes up, forcing me to close the app, clear the memory, and relaunch the app before continuing.
Were you using the default app and/or Swype when you had issues? I'm going to try to factory reset my phone to see if it helps.
It's taken a couple of weeks for this problem to develop, so please keep us posted if this problem arises again on your new phone!
Edit: Also want to point out that when I text, I use one hand to hold the phone and only a finger to swipe my text. As such, only the one finger touches the screen.
unable to use touch screen. only hard key were working >>Note4
Hi everyone,
today i just had the same problem with the touch screen. no response at all .. after i tried and took out the spen .. and surprise it worked with the pen.

Same thing happened to me last night. The touchscreen became unresponsive while using chrome. The phone was a little warm but not bad. I didn't try the pen, sounds like a good idea. I am not certain it was a touch screen issue with mine. Almost more of a processor issue. I got the phone to lock. After pressing the menu or lock button to wake the screen it would take 5-10 seconds to wake. Then I could swipe my unlock pattern. It would not show any lines. I would wait, the screen would turn black after timing out in about 5s. The about 5s after I could hear the speaker make the unlock sound. I ended up doing a battery pull and that fixed the issue. Anyone else have something similar?
Should I try and replace it?

Observe to see if it happens when you're using other apps too. Chrome has been notorious for causing all sorts of problems, like reboots, freezes, etc on some devices.
Also it may be worth installing Chrome Samsung Support Library.

Got the same problem after 2 months of normal usage... I initially though I had installed a third party application which was causing the system freeze but this was not the problem.
- tried factory resetting and not installed any apps, but it is still happening
- When this happens if I take out the spen .... surprise it work. The pen allows me to do anything... But the touch screen does not work with fingers...
- I used the pen to reboot the note4... Still the same problem after reboot... I ended up doing a battery pull and that fixed the issue for.... a couple of minutes... Then the problem came back....
The only solution remaining was to return the phone.... They gave me a Note3 while my Note4 is being repaired...
That's a shame for a product of that price!
:crying:
Same thing is happening with my 2 months old note4 since two weeks ago. An horizontal line 1.5cm in width about 1/3 from the bottom of the screen, became unresponsive. At reboot it works sometimes then it becomes unresponsive again. It looks like in the image I attached, the difference is that the area is horizontal, not vertical. I'm taking my note4 to the store today for warranty, hopefully they will replace it. I haven't abused the device in any way, I have a screen protector since its first day.. I really hope this isn't a serious problem that affects many users.
Just like some of you mentioned above, the pen has no issues on any area of the screen.
Cheers!

Only S-pen works, touch screen with fingers wont work. you mentioned you're note4 is getting repaired, did they tell you what may have happened to it so that i'll get an idea of the cause..

Never purchase a device without a return / DOA policy. Not worth the hassle. If it hasn't been 30 days, you should call your credit card company or Paypal and place the amount on dispute, wait, you purchased from another market, please tell you didn't pay by cash.

I have this problem after I flash CWM recovery, before this was flashed with twrp recovery, I reflash stock rom with odin, I flash many times CWM and TWRP and I still have the problem, my warranty it's void now but I think to go at Samsung store to see if they solve my problem. This problem look like a driver for touch corrupted, if somebody find it out how to fix or have any ideea please weritte here, thanks you
I've started to have this problem as well, lower part of the left side of the screen sometimes registers touch instead of scrolling! Very annoying, tried to update recovery, tried tapping screen, doesn't help. The worst thing is I cannot reproduce the issue at will... It seems pretty random.

Unfortunately, if the phone is on Verizon, the dialing codes will be disabled.
Potential fix.
Please excuse the necropost But I came here looking for a solution from google and others may too. I found a way to solve this issue/s.
There appear to be two issues affecting this.
1. Overloading the processor.
2. Static.
If your touch input is lagging or doesn't register at all but then suddenly does a few moments later, its likely a type 1. problem. I fixed this by disabling resource intensive features such as s voice. This also improved battery life and overall performance considerably.
If touch simply doesn't work at all, but s pen works fine then the problem is more likely type 2. That being static buildup in your person. Simply touch something that can ground you and it should fix the issue. A metal tap should work. Be wary, you might even get a little zap as you discharge

Screen just started going crazy

I was just looking through my phone and it randomly started spazzing out. I tried to just lock it and unlock it and see if that would fix it, now it is stuck in a bootloop and the screen looks like an old tv without any signal. Any ideas on what I could do? http://www.youtube.com/watch?v=w7-fStaJkYQ

There's only one thing to do, send it in for a warranty replacement.

Unlock 6P when laying on Desk?

Definitely enjoying the Nexus 6P after getting it yesterday. After bringing it to work that, I have to say that it's a little frustrating having to pick it up to unlock it with the fingerprint reader on the back. Coming from a Galaxy S6 this wasn't an issue since it was on the front. Besides that I'm definitely enjoying this phone more.
I was thinking about getting a dock for it, but realizing it would be the and issue. This is where double tap to wake would really come in handy if a dev ends up figuring out a way to get that to work (if it's even possible).
I was going to try to look into making my fitbit a trusted device if possible which could help the issue. Anyone else struggling a bit with the same thing? I really like having the fingerprint reader on the back otherwise. Or anything else people are using for this? I definitely don't want to set a trusted location at work...
Thanks in advance!

are you to lazy to press the power button on the side and punching in a code?
While the phone is face up on the desk you can still unlock the phone by swiping up from the bottom of the screen and using your normal unlock method. The other option is to lay it face down and touch the sensor before picking it up.
I was thinking about not using Smart Lock because of the finger print sensor. I found it convenient to have it unlock paired to my smart watch because of this reason. I don't have to pick it up to unlock.
I Smart Lock with my Pebble Time, and a 5 second lock delay when not paired. I wear my watch when I'm out of the house but it usually stays within range and unlocked when I'm at home as well. I do find myself still using the fingerprint scanner to wake the device as I take it out of my pocket even when a PIN isn't required.

Unfortunately I've never found smartlock with a fitbit reliable. It only senses the fitbit when the fitbit syncs....it's not always connected. But for real....press the side button and punch in your pin. 1st world problems.
I turned off the finger print scanner for this reason alone. Now I'm just waiting for NRT (I'm too lazy to manual root these days) to be updated so i can root it and fix the rotation on the lockscreen and hopefully add double tap to wake as well. I normally have my phone on a cell phone stand when I'm at my desk, so its always in landscape. Not having the lockscreen able to rotate is dumb, especially in the car. I'm also thinking of just putting one of those NFC stickers on that cell phone stand at work. Just need to find the ones i have.
Dt2w is available with flar2's kernel now
Double tap to wake is available with stock kernel, as well. Just need to enable it using the code in flar2's kernel thread. Of course, this requires root.
On topic, I find myself lifting the phone up to use my fingerprint to unlock the device. Sure, I could double tap it and input my pattern, but it seems easier to just pick it up.
Wasn't trying to come across as lazy (although I'm sure I did!) Just adjusting to the fingerprint reader on the back and was trying to get different thoughts. I'm possibly going to give double tap to wake a try, thanks for mentioning that.

Dont worry about it, I don't like it either. A sensor in front is just as easy to use and unlike the rear sensor can be used without picking up the phone. Nor do I want to enter in my very long and complex password every time I want to check my notifications, use the calculator, etc. as the phone sits next to me on the desk. Calling this lazy is baffling to me, I work hard to lay out my phone out and configure it so it can perform with absolute maximum efficiency allowing me to get get to and use any application or the phone itself with the minimum time invested. Of course everyone knows they can enter their password as an alternative, suggesting it is pointless and why anyone would want to I cant guess.
For me in the most part it's a non issue because the majority of times when I have the phone sitting next to me in that scenario it's at work or at home and the phone is already unlocked. Double tap and I'm rolling. Course I knew all this going in but I had hoped I'd make friends with the rear location and that hasn't happened and probably wont. I like this phone, pretty darn solid device but its not perfect.
If the sensor was on the front, people would complain it wasn't on the back. Can't please everyone with that.
In my opinion, it's in the perfect spot. Coming form a Nexus 6 and before that a Moto X 2013, I loved the dimple and always put my finger there naturally. The Nexus Imprint is the same way. Today I forgot my Pebble Time on the charger so Smart Lock isn't active. Using the sensor is working great instead of entering my PIN. I think the placement on the back makes the most sense because there is already a way to unlock from the front (touch screen). Putting both on the front would likely mean a bigger device/smaller screen or very odd placement (off the the side of the speaker or something). The only happy medium would be putting it on the side with the power button, but that could still mean you'd wear out the physical power button using it all the time. The Nexus Imprint has no moving parts and saves your power button for the good stuff like getting into the bootloader.
I use smart lock with locations for my home and office so i don't need to unlock the phone when it's on a desk at work or at home. I also set my phone lock to 20 min after sleep and to not lock instantly when power button is pressed. I don't see the need for your phone to be constantly locked. If I leave it somewhere it will lock in 20 mins but if I'm actively using it then I don't want to to keep locking.

I do the same thing. I made home and work trusted places and use the phone at my desk without having to worry about unlocking it.
I personally use Smart Lock with my Moto 360. Works well for me.

I don't use it, but I've seen people say that it works better if you setup four locations directly around your home instead of just one centered on it. This way they overlap and if you're in any of them, you'll be unlocked. The very center being the most saturated area with all four circles overlapping.
