Screen turning on randomly at lock screen - Android Q&A, Help & Troubleshooting

Hi,
Hoping someone can help.
I've got a Samsung Galaxy Note 10+.
Since yesterday I've noticed that the screen will randomly turn itself on if I turn it off at the lock screen manually.
For example, the phone is at the home screen - I press the on/off button - the screen stays off.
I press the on/off button (to check the time for example) and I'm presented with the lockscreen (no security) - I then press the on/off button again to turn it off - 1 second later the screen turns on, shows me my home page wallpaper then flicks to my locks reen then turns off.
And it will continue to do this unless I go to my home screen and turn it off from there.
Not sure HOW or WHY its doing this.
Haven't installed anything recently...
One thing I have noticed is that this will only happen if the lockscreen is set to SWIPE (No security) - It doesn't do this if I set a PIN for example.
And suggestions would be appreciated
Cheers people.

Lock screen not turning off unless I do it manually (5.1.1)

I am not sure if this is a bug with 5.1.1 or not. I tried searched before coming here to post, but I haven't come across a solution yet.
Anyways, my phone doesn't have power saver on, smart stay is off, and I have my security set to fingerprint unlock.
To the issue at hand - My screen doesn't automatically time out if I press the home button or the power button to turn on my screen. In order for the screen to turn off, I have to manually press the power button. Otherwise, the screen just stays on and drains my battery. This wouldn't be too much of an issue if my butt didn't always press the home button while the phone was my pocket.
I'd really hate to factory reset or flash another rom, as I just finished installing all of my apps and whatnot after a phone replacement. However if that is the only option to fix this problem, then I'm okay with doing so.
Thanks ahead of time for reading!
**quick edit** - forgot to mention that if I receive a notification, that it turns my screen on and keeps it on until I press the power button.

Galaxy S6 Edge Lock Screen Shut Off When Locked

So all I can find online deals with the normal lock screen timeout. However I'm concerned with when the phone is already locked and you hit either the power button or home button to light up the phone and see notifications. When I do this, the screen does not shut back off, it stays lit up at the lock screen. I found out that is does lock when the normal screen timeout (set in settings) goes off. I would like to have my screen timeout at 5 minutes but I don't want my normal lock screen to light up for a notification and stay on for 5 minutes. On other phones it wasn't connected like this and turned off after 10 seconds or so. Any help is appreciated. Thanks

Turning screen off with an app

I came to Samsung from HTC and one of the inconveniences I am having with the s9+ is turning the screen off. Of course I can turn screen off with the power button, but I prefer to turn off by a double press or a long press. Since I could not find a way of doing those I tried to use an app to turn screen off. The app works well in turning off screen, but the problem is after turning screen off, I cannot unlock the phone with the fingerprint scanner or any of the other unlocking sensors. I can only unlock with PIN if I turn off screen with the app. This is the app that I have been using. https://play.google.com/store/apps/details?id=com.katecca.screenofflock&hl=en
Appreciate if anyone can help me find a way around for this problem of fingerprint and other sensors not working after screen off with an app.
It's a security measure.. I suggest using this:

There's a lock button that won't disable the finger print and stuff. Hope this helps
I use an app named screen off. It puts a button on your home screen to shut it off. Then just double tap the home button to turn it back on.

Thanks. I tried that and it works without disabling the fingerprint and other sensors. Only thing is it takes two touches to turn off the screen.
Take a look at Lock Screen Pro, it has an option in its settings that will allow fingerprint and iris scanner to work after locking with an app symbol you added to your homescreen. If you use bxActions you can also lock your device with the bixby button!
Use Nova Launcher, better than Touchwiz and has a setting built in for double tap screen off, no problems here with finger print sensor. No need for secondary app.
Long-press on home button
Try a long-press on the home button. A long-press turns on and off the Samsung S9+.
I knew of its function to light the screen, but was unaware that it would close the display.
Greenify is installed on my phone, and a message appears, stating that Greenify is still working, and that I can press the power button, if I want to stop it, then the screen is off.

How to disable auto screen turn on when we pick or move realme 1?

When I pick the phone or move it the screen turns on. It is annoying. Is there a way to only turn on screen by pressing power button? Please help.
Go to settings->smart convenience->gesture & motion and turn off Raise to Turn On Screen
I have already done that. But the screen still wakes up without any notification or pressing power button.

Mine too
Disabling Auto Screen-On
Go to Fingerprint Settings under "Fingerprint, Face & Passwords" Section and Turn Off " Display the Fingerprint Icon when Screen is Off" option.
Faced the same issue, switching that off in Settings doesn't help!

Question Last few morning's my screen has been locked and can't swipe open

Hi, not sure if anyone else has had this issue.
It's only really been happening to me the last few mornings when I wake up.
My screen is blank, the top half (no clock showing) the bottom half shows the bottom half with the fingerprint and if I touch anything, it's just frozen.
My alarm has sounded while it's been like this, and it shows the slider to turn it off, but again won't actually slide when I try, so the alarm keeps sounding.
The only way i it responds normally is if I press the off button to turn the screen off, then press it again to turn it back on, and then it seems back to normal.
I can't think of anything I have installed recently that might be causing it?
Anyone got any ideas please?
Regards
James
Do you use goodlock and custom clocks on aod and lock screen?
I do use goodlock yeah, thinking about it, I did recently charge a setting for aod to wake up notifications. It's there a glitch with that do you know?
I have had my screen go black and wont respond to any presses. Then when pressing the powerbutton the screen shows the home and back button only but responds to nothing, except I can use the sidebar, click on calander for example and then it allows me to unlock. Did this a few times but has not done it again after a power off and on.
