Lockscreen unlock lag - Nexus 4 Q&A, Help & Troubleshooting

Am I the only one who has been having issues with the lock screen locking up on unlock? had this issue before I rooted am still having this issue.
Find i have to relock (power button) a few times before it starts to work!

Haven't had this problem. It has been smooth since stock. I find it weird that you had the issue before rooting.
Do you have any custom kernels? Any homescreen widgets? Does it happen consistently?

Nope, none, no stock widgets or anything like that, about as stock as you can get.
Happens once every 10 unlocks i would say, might have to send it back!

I can confirm this issue
Face unlock is on with pattern unlock as backup
Whenever face unlock fails I try to enter pattern....pattern does not work
Phone doesn't even show pattern(like its not accepting touch input and I do have it set to "show pattern" )
Slide up to Google Now when unlock pattern screen appear and you get new unlock pattern screen.....entering pattern here works
I suspect it is related to face unlock....when face unlock fails it never locks for touch input
This error occurs 70% of the time not always

I have removed root etc done a fresh wipe and still have the unlock lag issue l, i don't use face unlock. going to try and get a swap from o2 today.

Used to have this problem when using autobrightness

Mine has hung a few times on the lockscreen and each and every time it has, Auto brightness has took a dump.
I don't recall it doing it more than one per reboot though, I'll have to monitor that.

Yes I have this exact issue and posted on it about a week ago in the Q&A forum.
I push the power button and I cannot drag the slide unlock. If I wait 10 seconds it sometimes unfreezes and lets me. I have to cycle the power button until it finally lets me slide unlock.
I've completely wiped the device and that has had no benefit.
What apps do you have installed? I've wondered if it's an app.
I use Words with Friends, IMDB, Reddit is Fun, Tapatalk, and Google News & Weather widget. I'm going to try disabling auto brightness to see if that fixes as suggested above.

Ended up getting a new N4 from o2, no longer have the issue, same apps installed must of been some random hardware issue!

Been having this issue, so annoying .

I believe that this is a known very occasional intermittent 4.2/4.2.1 android issue, I have had it a couple of times myself in the last fortnight.

This happens to me all the time. Super annoying! I don't use auto brightness and it happens with any lock I use, slide, pattern, pin. Should I contact Google?
I'm 100% percent stock, not even rooted.

I have also been experiencing this, really is infuriating not being able to unlock your own phone sometimes... Usually cycling the screen on and off a few times seems to work.
I ended up ripping off my brand new BestSkinsEver thinking it might have been the cause!

Same here. In my case, i am using PIN and sometimes it lags out while trying to enter my pin and i have to press power button to lock it and try again.

I have the same problem, and I think i have found a way to replicate the issue.
1. Turn off the screen.
2. Wait around 5 seconds.
3. Put three fingers on the screen at the same time.
4. And without moving the fingers turn on the screen.
At this time the touchscreen doesn't respond or it has some kind of lag and you have to reunlock the screen to make it work again.
Can anyone test this?
Sorry for my english.

This way the lock screen is unresponsive but I feel that it is not the same issue.
The lag I usually experience with the bug is more like the phone doesn't wake up properly and can't handle the input in (real) time
PS. I had this on my 8 GB model (sold) and 16 GB model

Widgetlocker with Launcher Pro on Epic 4g

Hey guys, I'm having a little bit of trouble with Widgetlocker and launcher Pro.
Basically, I'm using widgetlocker as my lock screen. The problem is that when I press the power button to turn on my phone, I see my home screen for a bit, and then widgetlocker kicks in a second or two later. Is there a way to get rid of this little bit of lag?
Thanks!
EDIT: based on what I'm messing around with right now, it seems that this lag exists only when I shut off the screen then turn it back on soon afterwards. Still have no idea how to fix it though
Don't waste ur time just download lock not pro ...its bad ass..B-)

hmm, lockbot pro seems to be kinda laggy too. I have to use no lock or else the original lock screen shows up first, before the custom one pops up. After that, it takes a second or two to load up the background picture

I have that same setup widgetlocker/launcher pro plus and do not have that issue with the delay...have you looked into your locker settings "HomeHelper" and the "5 second root bypass rule"?

Yea, I've tried messing with those settings. No use though :/
Also, just wondering. Is there a small lag from when you hit the power key to when your screen shows up? I tested it, and widgetlocker takes a second or two longer to turn the screen on versus the stock lock screen. I'm currently blocking the stock unlocker with no lock. How are you doing it? (Am I doing it wrong? :c)
Thanks for the help so far
Same here - I've had similar issues and not much seems to fix it. I may try contacting the developer about it.

I have my screen to light up with either pwr/vol or cam keys pressed, most of the I use the vol keys to light up the screen. There is a delay, but I think it is cause by the setcpu set at 200 when screen is off, so things are running alittle slow when I press the buttons to turn on the screen, its not bad enough to drive me crazy.
When I have it plugged in, the cpu runs at 1.2 and the screen turns on quick with little to no delay.
I remember a setting somewhere that changed how long after you turned the screen off until the phone locked. I just did a quick look and I didn't see it in LP or in Spare Parts. Maybe it was in CyanogenMod on my Hero? I wonder if that would help with the problem. One day we'll get CM and all be happy with our phones.

1.8.3. Issues: Screen and Finger Scanner

Since 1.8.3 I have noticed 2 very annoying issues:
1: Several times a day, my Atrix will stop detecting a finger swipe. No error, just no response. I must reboot to regain finger scanning.
1: Screen Timeout: The screen will frequently, but not consistently go off after only a couple seconds of idle time. It doesn't dim first and if you hit the power button it comes back to the screen you were on, not the lock screen.
Both of these issues happened with vanilla 1.8.3 and with Gingerblur and NEVER before the update.
Anyone else?
Fingerpring issue for me as well but also the button sometimes wont put my phone in sleep and ill have to pull battery cause its unresponsive but never the screen issue you're having. This update is full of bugs they need another update fast just to fix what this one broke. Oh and I think about 90% of people that updated have reported an issue with the fingerprint scanner
But thats just my 2 cents
Sent from my Atrix
If both of these issues are known and have been reported, feel free to lock or delete. I searched and didn't find any thread titles about this, but did not read every 1.8.3 thread.
I met the fingerprint issue too after 1.8.3 upgrade

i had fingerprint sensor issues too, when i had stored fingerprints and restored settings for fingerprint sensor using Titanium backup. A wipe data may solve this(int titanium backup).
in 183 there is a new setting in Location And Security!
The phone is not necessary anymore to lock, when the screen goes off.
the screen can go off in 5 mins(in display settings)
and the mobile can locked in 10 mins(in location and security)!
i like this setting!

I don't see it either in 1.8.3. The item "Security lock timer" that would be used for this is disabled (grayed out).
fingerprint issue here too just experienced for the first time yesterday.
i swipe it and there is no response.
good that there is a list of people here with the same issue so motorola can acknowledge it as a legitimate bug and hopefully fix it
Can someone else verify this? When I change the screen timeout from 15 to 30 seconds, then reboot the phone, it switches back to 15 seconds.

this sounds like the GingerBlur 3.0 bug...upgrading to 3.1 fixed this for me
I am having issues with WidgetLocker and the fingerprint recognition, has anyone else experienced this issue with WidgetLocker? I have been having no issues, with the fingerprint scanning, once I turned off WidgetLocker.
Yes.
You are right!
I now recorded again fingprnts and that setting grayed out!!
I didn't used fingerprints cs some probs I had after restoring settings from backups, and waited to have 183 with 3.0 gingerblur..
Sent from my MB860 using XDA App
I found that powering off the device, pulling the battery for a few minutes, re-installing the battery, turning the Atrix back on, then wiping and re-doing the fingerprints permanently fixed my issue.
This issue is not the same issue as when TiBu backs up fingerprint data. This is an issue with the scanner being none responsive. OP this issue has bot be talked about here but on the Moto forums it's been reported by many users.
But thats just my 2 cents
Sent from my Atrix
I also had my first fingerprint issue since owning this phone for the first time yesterday after getting 183. Never had it ever before...somethings wrong with this update if multiple people are getting it for the first time now.

add me to the bad fingerprint group
Same issue with Widget Locker. Sometimes when I hit power, I can swipe finger and all is good. Other times, swipe does nothing - I have to slide the screen lock, then I can swipe (or enter PIN).
Can't seem to find any pattern to when it works or doesn't, but it does do this pretty often. Good thing is, it doesn't completely lock up - if I don't get the double-vibrate for a bad finger swipe, I know that I need to do the screen slider first.
Just to add to the people on the list, I experienced the fingerprint issue once, hasn't happened since though
the best thing to do is actually complain on the motorola support forum ...
i already did
https://supportforums.motorola.com/thread/50138?tstart=0
moto engineers actually look at that forum ...
So I read this thread and thought to myself, "Self, Thank G-d you don't have this problem." And then, of course, I jinxed myself. Add me to the fingerprint issues list!!
I did a power-off, battery remove, battery install, power-on, remove fingerprint data, reboot, then redo fingerprint calibration. If you don't hear back from me, assume it resolved the issue....otherwise, I'll report back....
How absurd?!

Help! Several major issues on 4.3 (home button, SIM, lock screen)

My N4 was away to repair a broken screen. Got it back on Wednesday and it immediately updated to 4.3. All was well, except for one weird issue where hitting a notification from the pull down would take me to the app via the pattern lock. I put this down to having played with some lock screen settings in Setting Profiles app (trying to disable it in certain settings), but it might not have been.
I've done the first device restart today, and after rebooting there are a few big issues.
1. I don't appear to have any mobile network, though wifi is connected. I had a good signal before the reboot.
2. I'm not getting a lock pattern or any lock screen at all, and it's not asked for the SIM pin
3. Hitting a notification in the pull-down makes the 'lock' clicking sound as it takes me to the app
4. The home button doesn't work. I see a slight dim of the screen and it makes the lock click sound, but nothing happens. Back and multitask work fine
Help! Any ideas? Are they known issues? Can't seem to find any reference online.
I'm on stock, using Nova Launcher

Those are not any known issues or anything I have read since Andrid 4.3 came out. Try a factory reset to see if that solves the problem. If not, maybe the screen wasn´t the only thing broken on your device. Ask for warranty.
Thanks, will see how I get on this evening and try a factory reset if it doesn't fix itself.
Seems to be a weird problem related to the lock screen and when it should/shouldn't kick in...

Glad I could help.
Ok, I've done a factory reset. Not had much chance to play as it took hours to reinstall everything. But I've just had the word issue where selecting something from the notification tray (the setting profiles shortcut) took me to the lock screen to put in my pattern first, then took me to the app.
EDIT no pattern to when it does it, seems random and can be while I'm using the device, so the lock screen shouldn't kick in for any reason
Any ideas? Faulty device?

Imprint bug

Is there a way to unlock the phone right away by using imprint? Mine keeps asking for pin or pattern after it recognizes the fingerprints

Are you using a double tap to turn off app for your screen? They interfere with it.

Is this happening every single time you use your fingerprint or only after a boot/reboot? It should only occur once after each time the phone has booted up.

Same problem here. Sometimes it asks for the passcode after the fingerprint. Sometimes on bottom of the screen the print sensor icon is replaced by a lock. I just had another bug where I was on chrome browsing a website and the lockscreen appeared by itself.
EDIT: I uninstalled this app https://play.google.com/store/apps/details?id=com.qihoo.security&hl=fr and it seems to not happen again for the moment. (I also tried to disable lockscreen security, then enable it again, registering my fingers again but it didn't solved it)
EDIT2: Oops it did it again.
Go to Security-> Device Administrator and untick all the apps. Lock your phone with power button. Now, try fingerprint.
Probably one of the apps there is misbehaving.

Same thing kept happening to me, I realised that its because I used a screen lock widget on my home screen to lock the screen. It didnt work when i did that. But if i use the power button to turn screen off, it goes back to the normal imprint mode.

when i put my finger of the scanner it open the pattern lock

somethimes when I put my finger on the scanner instead of unlock it it ask for the pattern password and sometimes it works well.
(when I try with finger that isn't in the system its vibrate and do nothing so from this I figure that it does recognize my finger when I use the right one and it open the pattern)
what can I do
Edit:i found the problem I was used an app names screen lock that make this problem if someone have the same problem check if u use an app that have connection with the lock screen you can check this is settings security
It asks for the pattern on the first fingerprint unlock after a reboot. Could it be your case?
Inviato dal mio Nexus 6P utilizzando Tapatalk
It will do this when you first restart your phone.
Happens on every reboot, as @lomax79 and @geoff5093 said. I have also had it occasionally ask for my password for "extra protection".
do you have a lock screen replacement or perhaps you are using a launcher that has lockscreen settings enabled?
if so, that is likely the 'issue'. Try disabling it/them.
I occasionally get the password screen after attempting to unlock with a fingerprint. This is not after a reboot, just random times throughout the day. At first I thought it was random reboots while in my pocket, but the uptime clock has not been reset.
I've been getting this from day one and it seems to have good times and bad times regarding g how often it happens I could understand it happening if I was buying something.
Oh and it seems to happen more if I shut the phone down with Tap screen but if I put phone down and let it power down on its own it won't ask for password on next restart, bugs me a bit.hope Google can polish it up a bit.

It's not happen just after reboot it happen sometimes per day
It's possible your phone has been constantly rebooting. The only time it will ask for your pin or password is when you first boot up the device as an extra security layer. I've RMA'd my current device for that reason as well. Expecting a new one Monday. If the problem keeps happening I'd recommend RMA'ing
found the problem
