Lockscreen unlock lag

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.

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

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?

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

T-Mobile s7 edge: why can't I use ONLY fingerprints to unlock my phone?

OK, I found one issue that might actually make me return the phone if this is the case.
I set my fingerprints to unlock my phone, but it says additional security is needed when I use fingerprints, so it's making me input a pin EVERY time I use my fingerprint to unlock. Wtf? This didn't happen on my s6. I can't figure out how to turn this off.

Mine only makes me put in my pin the first time I unlock after powering on. I don't like it but it's not too much of a bother. Not sure of the reasoning behind it. Yours is every time?

Yep, just did.

Found the problem.
I'm using Nova launcher and I use the double tap screen to lock the device. When I double tap to lock it and then wake it back up, it makes me use my fingerprint and pin. If I lock it with just the power button then it unlocks with just my fingerprint. Didn't have this issue on my s6. Weird.

I have same problem with s6 after update to 6.0.1
it was after reboot not every single time.

That's the change Google made to Android. It's not a Samsung "feature." The Nexus 5X has that too and it bugs me once in a while.

What's the point in having finger print reader for security if you have to enter a pin anyway? Makes no sense to me. It would be much quicker to use pin only! What a useless feature.

As mentioned above, this is a change to Android. When restarting the device, it asks you enter your pin manually. I don't mind it, since I seldom restart my phone anyway.
Sent from my Nexus 6P using Tapatalk

Even iphones make you enter a pin upon restart. But only after a restart.
Don't see a problem with entering a pin once when you restart.

I restart my phone maybe once a week. This is a complete non-issue.

Agreed

Has anyone else noticed how sh*ty the fingerprint scanner is? It only works half of the time for me which is annoying. I have a Nexus 6P so I'm used to it being a seamless transition to unlock the phone. I've resetup my fingers a few times now but it's annoying how it doesn't register sometimes.

Ah, if it's only required every restart, this is not an issue for me

Christ, you really do have a hangup on this thing.
I specifically asked to try out the fingerprint scanner in the Samsung store on Sunday and, once I set it up, I spent a number of minutes locking and unlocking it using the scanner. I did this because my previous experience with Samsung's fingerprint scanner was on the S5 and that was poor. On the S7 I didn't have a single issue, not one unlock failure. Perhaps you have a faulty device?

Don't get me wrong I still like the phone, but there are several rather interesting issues I've noticed. My 6P isn't without issues either, but it happens.
I could have a defective unit; I'll have to use it more before I see if it continues. The S7E usually says place your finger on the scanner and 'wipe' which doesn't make sense because it's a touch sensor not one like the S5 had. Either way Google certainly has the best FP scanner so far until someone else makes one that's as fast and accurate.
Sent from my Nexus 6P using XDA Labs

My S7e fingerprint scanner is working great, no problems.
The device asks for the unlock code only after reboot, as previously stated. Any other time the unlock number pad shows up, my fingerprint bypasses it. Why does the unlock number pad show up sometimes? Because I sometimes turn on the screen with the power button and immediately swipe the screen before I touch the home button sensor. But if I turn the screen on with the home button, and leave my finger on it for a split second, it unlocks flawlessly.

You definitely do not need to swipe on the S7 Edge. That went away with the S5 reader. If you have the phone in a case, then your finger may be hitting the scanner in a way that it can't read it completely. Although I have yet to run into it with the S7 Edge, I had it all the time with my Note 5, and I fixed it by enrolling the same finger twice. Make sure to contact the sensor from all kinds of weird angles on the second run and you'll be fine.

Haven't had it mess up once. Seems a little faster than the s6 even which was pretty much instant for me. On s6 I found adding a second fingerprint of the same finger improved accuracy if I was having problems though.

Screen Lock Problem - Randomly Stops Requiring Passcode/Iris/Fingerprint

After a couple days of using my phone without a reboot I notice that it stops requiring unlock credentials such as my pin, iris or fingerprint. I will be able to swipe to unlock the phone and the security is completely removed.
Has anyone else noticed this? If I reboot the phone the security goes back to normal.
The only app I have that I think could cause this is BxAction to remap my bixby button to google now.

Under settings > security > smart lock there are options for keeping your phone unlocked in certain situations, e.g. in trusted places or when connected to a particular bluetooth, check to see if nothing is enabled there, and usually it locks after a reboot like you listed

Stupid question: have you enabled face recognition?

Did you set your screen lock to happen immediately or is it delayed?

Ok so I uninstalled bxactions to see if it was causing the problem. It appears it was not the culprit.
I currently have my phone setup to use iris, fingerprint and pin. It will work normally for approx one day.
Then all of a sudden it doesn't require my credentials to unlock. I have smart lock setup to not require credentials when connected to BT in my truck and when at the GPS location of my house. I'm currently sitting at work and it's swiping to unlock without reading my iris or fingerprint.
My lock delay is 5 seconds and auto when I press the lock button.
If I reset the phone it starts working normally again.

Now that I think about it I have a feeling its something to do with smart lock thinking I'm either still at home or that I'm still in my truck.

I'm having the same exact problem and I have the same exact setup as you! It started doing this a couple days ago. I have Smart Lock set to keep the phone unlocked when I'm at home (GPS coordinates) and when connected to bluetooth in my car. I got to school yesterday and noticed the phone wasn't requiring my irises or fingerprint anymore. I let it be for a little while to see if it would correct by itself and it didn't. I restarted the phone and that fixed it but it did it again this morning! It seems as though Smart Lock isn't registering I'm not at home or in my car. This is huge security flaw.

I just went home on my lunch break and the screen lock is still working normally. I connected to my truck when I was on my way home. I didnt pay attention if it was requiring any type of unlock when I was home.

I don't have that setting checked either. Just bt for car and gps for house. Not a huge deal for me personally because I'm pretty much always around people I trust but this really is a huge security flaw if it is happening to a lot of people.

Are you looking at the screen when swiping the lock screen? The iris recognition is actually very fast and you only see the alignment screen if it cannot immediately read your iris.

I haven't had it happen since the day after creating this post. I wonder if some Samsung apps were updating over night and causing the issue.

Weird how they would be linked. I did notice that my fingure print gestures stopped working the other day too. I turned the setting off and back on and it started working.

After several days of the phone working properly when I traveled out of town, it is doing this again. I am at school, which is not a location I am using for trust locations, and the phone is staying unlocked. This is honestly pretty ridiculous and needs to be addressed. The only thing I can think is that I am connected to the same wifi network at my apartment (campus housing that is off campus) and while on campus. Maybe the phone is thinking I'm still in the same location since the wifi networks are the same?

I just tried this as my screen lock isn't currently not working.it didn't make a difference having gestures turned on or off. I tried turning wifi and GPS on and off as well. Only way to get it to work again is reboot.
