Samsung Galaxy S10+ issue with double tap to lock - Android Q&A, Help & Troubleshooting

I have both a S10+ as well as a Note 10+. When setting up Nova Launcher I have enabled double tap to lock. Went into the accessibility opens to ensure it is turned on for Nova. Everything works fine on the Note 10+, when double tapping the screen turns off properly. The S10+ screen turns off when double tapping than turns back on to the lock screen. Loving everything about this phone other than this little quirky issue. Not a fan of the Device Admin app method as the facial unlock doesn't work when waking the device the next time. First person that comes to a solution gets a prize.

[Q]TV-Off-Animation with Screen Off and Lock on the S3?

The app Screen Off and Lock offers the option to turn your screen off with just one touch or - if you have a custom launcher - with a specific gestures.
One cool feature is the "TV-Off-Animation" which you can see in this video:
I thought this was cool, so I downloaded the app and made all the settings.
The issue with the S3 is, that when you turn off the screen with a gesture or a widget, the screen turns off for half a second and than the lockscreen pops up...
Do anyone have a solution?
push...
I don't have a permanent solution, but i find turning off S-voice for wake up device helps, the double switch off as i like to call it still happens but not as much.
Another success i had was switching everything off the home screen so its blank, This fixed the issue until i pressed the power button once to switch off the screen then the issue came back.
I used a similar app called lock screen but the issue remains, actually the screen off and lock app seems to be better because of the delay it has with different animations.
It seems to be an issue with ICS 4.0.4.... So we have to wait
Does this work with the physical power button?
Nope...

Gear S messing with Note 4 lock screen

Just got a Verizon Gear S today, paired with my Note 4. I use the fingerprint lock screen on the Note, and noticed that when the Gear is paired with it, I have to go through two lock screens - a simple swipe screen that then leads to the fingerprint lock screen. I have to unlock the phone twice, which I really don't like. As soon as I unpair the two, the lock screen works as normal.
I've searched the Gear for some kind of setting that would cause this, but can't find one. Anyone else seen this or have any ideas?
Thanks.
EDIT: Actually, it's worse than I thought. The top swipe lockscreen totally bypasses the fingerprint lock, so I have no security.
Nevermind. I had set it up as a trusted device. My bad, I'm an idiot.
It took me a while also to figure out the trusted device thing

Lift to wake, double tap, and lock security flaky?

Anyone else notice lift to wake sometimes doesn't work? Sometimes it's fine, other times there's a few second delay, other times I can shake the phone after picking it up and nothing then it finally comes on. Googling shows intermittent reports over the last year or two of similar symptoms on the 2 and 2 XL.
Also, double tap sometimes does nothing. Tapping again usually works. Sometimes it works fine several times in a row, then fails again.
Lastly, I have fingerprint lock enabled. If lift to wake works, and double tap gets me to the lock screen sometimes I can swipe up and get the home screen. Other times it forces me to use my fingerprint.
Quite a bit of flakiness in this whole area. Things appear to be working fine once I'm in, but getting there is quite inconsistent.
I did contact support, tried various things they suggested including booting into safe mode, but didn't fix it. They're supposed to get back to me...

Definitely noticed this on my 3XL. It's like it doze's a little too hard or something. Usually doesn't react properly after long periods of inactivity. Same with FP on my P3. But sometimes the FP is fine, like you say it's flaky and inconsistent. Maybe something that will be tuned a little better in an update or with a custom kernel in the not to distant future....

Couple of things.
I ended up disabling FP and then setting it up again and since then the FP detection has been much more consistent. Maybe sometimes the process for the initial FP scan isn't very good and that might cause the security scans after that to be inconsistent. Just a guess. Anyway, resetting it might help.
Also, the comment I made about sometimes I can just swipe on the lock screen and not have to use FP was due to having "Smart Lock" enabled. It's a bit confusing (at least to me) in the Settings screens. Under Security > Advanced > Trusted Agents > Smart Lock can be turned off. I did that and now it always requires my FP.
One more thing. The swipe on the FP scanner to bring down the notification panel is very flaky for me. Works only about 50% of the time at most. Also went over that with support. Waiting for them to get back to me on that one as well.

Most of the stuff you experienced is standard operation for phone's with Double tap to wake, lift to wake, etc. Those features just kinda go to sleep after a while. And yes, smart lock keeps you logged in during certain situations that you specify. Welcome to Team Pixel!
Don't use a lot of those features, but some OT thoughts..
I think there is some FP lag if you have lift-to-check enabled because it's 'lifting-to-check' while i'm hitting the FP. I disabled lift to check and i'll see if the FP's a little snappier.
Always helps to redo the FP after you change a case too- I usually do 2x on each index finger.

Every phone I've had has quirks. It is a bit disappointing a useful feature like lift to wake, especially with no notification LED, has been flaky for so long it's now accepted behavior. I tried a location smart lock feature on my previous Samsung and quickly abandoned it as unreliable as well. What seems odd and a bit confusing is the Smart Lock on/off switch is in a totally different place than where you set up the specific settings, some of which get added by default. Really like the phone, just a bit of acclimation.
Do you have your battery saver on? I found that after I turned off my battery saver it worked

I had battery saver on. I've turned it off for now to see if that helps and how much extra battery gets used. Thanks for the suggestion.
Update: That didn't take long. Lift to wake is still flaky. Works sometimes, other times not.
I've noticed the same. I use smart lock with a Garmin watch. On my Nexus 6 it always worked, and if I didn't have my watch on, when I swiped the screen it would ask for a PIN. Now, I lift or double tap and sometimes it will then let my swipe the screen, but most often I have to hit the power key. This is not an improvement.
Can't believe no one has figured this out. It has to do with the lock to sleep delay. By default it is set to 5 seconds. So, madly tapping won't work. Go into settings and change the timing. Be amazed.

Question Lockscreen is broken on my main profile

I've been documenting my struggles with my lock screen in another thread. But I just had a major breakthrough and didn't want this to get buried.
To recap, my lockscreen has been a buggy mess from day one. The fingerprint sensor barely works, the fingerprint icon randomly disappears, and the gray border that's supposed to appear around the fingerprint icon simply doesn't show up. The lockscreen doesn't light up when I pick up the phone either (it stays dimmed). Also, wallpapers don't show up on the lock screen, and the big ugly clock sometimes disappears or moves itself to the top-left.
I've tried just about everything to fix this. As a last-ditch effort, I added a new user profile only to find that the lockscreen works perfectly well for this new profile (but still not for my main one).
Here's my main profile with the unusable lockscreen:
broken lockscreen of main profile
Watch "broken lockscreen of main profile" on Streamable.
streamable.com
And here's what it looks like when using the other profile:
working lockscreen on new profile
Watch "working lockscreen on new profile" on Streamable.

So there's clearly some obscure bug that most people aren't experiencing here. I'd love to just figure it out so I can move on.
When I didn't have the "always on display" turned on, the phone was very consistant about turning on properly when I picked it up. I ran it this way for 3-4 days without any issues.
After reading some articles on the P6, I realized that it has an AOD and that it was turned off. So I turned the AOD on while leaving all the other settings set the same. At first, the finger print icon wouldn't appear consistantly, but that is because I had adjusted the animation scale settings in the Developer settings. Changing that back to stock fixed the issue with the finger print icon not showing up.
That beings said, I have experienced the same "unresponsive" screen many times over the last couple of days that I have had the AOD turned on. The screen stays dimmed (or even turned off if I pull the phone out of my pocket) and the finger print reader is inactive (even though the icon is displayed). The screen is suppose to turn on when I lift the phone up, but it doesn't always do it. When this happens, I have to either manually turn the screen on using the power button, or double tap the screen to wake it. This is clearly a bug in the system somewhere. I probably need to report it to Google, but hopefully it is fixed soon.
After spending way too long on this, I've determined that the bug occurs consistently with these specific settings (although it may also occur for similar ones):
Lock after screen timeout: 30 minutes (or anything high enough to prevent it from locking between tests)
Power button instantly locks: disabled
Lift to check phone: disabled
Tap to check phone: disabled
Always show time and info: enabled
Replication steps:
1) Enter the above settings
2) Press the Power button to go to the lockscreen
3) Set your phone down for a couple seconds
4) Pick your phone back up and try to use the fingerprint sensor
Result: The fingerprint sensor won't work the first time.
I think all the other issues I had were actually stemming from this one issue.

Question Fingerprint sensor

I don't know anything about how under-screen fp readers work, but... Is there no way to use it when the screen is off?
On previous phones I always used the fingerprint sensor to turn on and unlock with one touch, but this N20 5G seems to only fp-unlock when A) The screen is on, and B) The "fingerprint goes here" icon is visible.
The screen will usually turn on when I pick up the phone ("Somatic Gesture"); the fingerprint icon then appears for a few seconds, then goes away. That seems to be the only window for unlocking without clicking the power button.
Am I missing a trick?
I use double tap to wake and it works great. The sensor stays lit up for about 7 full seconds before going black. YMMV
Good point, double-tap to wake was disabled by default!
Still two more taps than I'd prefer to get to the fingerprint unlock, but I guess that's more a reflection of how incredibly lazy I've become than a problem with the phone.
