Lock Screen random, even while in use??? - Samsung Galaxy S9 Questions & Answers

Why does my Android 10 Galaxy S9 keep going to lock screen randomly, even while I'm actively using it, like when I'm typing in a any like this? In the Settings I've got the Display time out set to 10 min and Lock Automatically is set for 30 min except when Smart Lock (No Body, Trusted Places) keeps it open.

To further clarify,
I'm using the same Otterbox cover that I've been using for over a year, it does not cover the proximity sensor.
This only began a week ago. It happens completely randomly, a few times an hour at least. It has happened while actively pressing app controls, or reading, or just ended a call.

Found the answer on a Reddit post. Settings | Developers Options | Lock screen when trust is lost. < Disabling seems to have fixed the glitch

App to display a black screen/pseudo lock?

Since we need to have the screen turned on to keep wifi/gps etc. running, and there are a few apps that would ideally run in the background with the screen off; to save battery power (and burn in?) it would be nice to have the AMOLED screen display just a black image.
Is there any app out there that just displays a black screen and maybe ignores all but a specific input?
At the moment I just zoom into a black image in the browser, but I can't put the phone in my pocket like that.
(I tried searching for this, but it was beyond my google-fu.)
You dont have to keep the screen on to run either my gps is always on and it neva disconnects also ive spent many nights going to sleep leaving my wifi connected and its neva disconnected either
Yup. If you haven't set WiFi to switch off after 15mins, it should carry on running.
By doing what you proposed, you'll decrease battery life drastically as you'd effectively be disabling the chips sleep mode by keeping it running 100%. With that, only the screen switches off and everything else including Android keeps running. Any application holding a partial awake lock can achieve this.
Lock delay; an app to control the default screen-lock options allows this.
For instance, if you set the initial screen timeout to 2 minutes but standby/lock to 10 minutes in the settings, the screen will switch off after 2mins idling, but the rest of the phone will still be running incl. WiFi/GPS. You can enable a lock/pattern or no lock at all where you press any key including menu/trackpad and it'll come back on in the same place you left it, without any lock. If the phone idles for 10mins, it'll activate the screen lock and place the phone in the standard sleep mode. The max delay you can set the latter to is 24 hours.
I wouldn't advise avoiding the sleep mode unless required in specific circumstances. Battery loss will be drastic; I found out unintentionally when activating this option at the beginning.

Thanks th3, that should do what I want. I don't intend to leave it unattended, it's just for when don't need the screen on while an app is doing something.

[Q] Anyone having issues with the automatic screen shutoff?

I am running CM 6.1 Stable, and have been for a while, yet this issue just popped up a few days ago.
I cannot get the phone to auto shutoff the screen when idle. I have it set to 5sec off and 1 sec lock, (down from 30 sec off, 5 sec lock before).
I have looked at the stock settings and all are in order.
The only thing different is I was trying to play with the setting on my Alarm Clock Plus regarding screen setup, but have reverted to original settings and even rebooted several times with no success.
Anyone else having issues with this? Any way to enable screen off again without having to flash a recovery?
It's really killing my battery fast!
Thanks for you help!

In the android display settings, 15 seconds is the least amount of time to turn off display. how is yours set to 5?
In cyanogenmod settings, theres options to tell the lockscreen to kick in after the screen has automatically turned off and when the user has pushed the power (sleep) button. what is your time set to in the android settings? (settings - display - screen timeout)

Um....finding rock, and hiding underneath it!!!
Turns out I am a moron that can't read.....but I swore that I had the display set to 30 sec....It was disabled. I will test again, over the next few days if for some reason it reverts to disabled.
Thanks!

Screen stay on when viewing?

All,
Coming from Samsung phones, it has this great feature that keeps the screen on if it detects you viewing it. Is there an app or a feature on the HTC 10 that does the same? Kinda annoying with I'm viewing the phone and have to keep tapping the screen to prevent it from closing.
Thanks!

Pretty sure only Samsung have that feature, in settings under "display gestures and buttons" you can adjust screen timeout value, from 45 secs up to 1 hour, you could at least just make screen stay on longer that way.....also in developer options you can make screen stay awake while charging. Not the answer you hopes for but these options should at least help
I had this issue to until I discovered Kinscreen from the play store which keeps screen on with motion or proximity sensor.
Give it a try, working well so far for me ?

Screen turns on itself randomly?!?!

Hi all, I started using my Pixel 2 XL yesterday and I got the first issue!
I set every settings into ambient display to off, anyway my pixel 2 xl yesterday decided to turns on the screen itself randomly for 4 times. Every time the screen turned on itself I could see the numeric pad of the lockscreen, the same use case you get when you have the fp scanner set and you just try to unlock the phone just swiping up on the lockscreen. The second and the third times were almost consecutive, while the first and the fourth times were quite far from the others.
As I wrote....I set the ambient display to off when I set up the phone the first time. I don't have any particular app installed dealing with screen nor battery management.
Today (second day of usage) I haven't got any spontaneous screen turned on yet...
Anyone else had a similar issue?
Thanks in advance

Nope....it's just done it again!
The screen has just turned on itself few seconds ago...I had a Netatmo notification in the notification bar....but checking it I saw it was 6 minutes old....then I think it's not the cause of this issue! :/

Always on display "flickering" when activated (on tap)

Hey everyone!
As the title say i'm facing a issue with my always on display.
I'll try to make it as simple as possible:
When I set the always on display to be always active it works flawlessly.
When I set the always on display to activate on tap (and last for 10 seconds according to the settings) it appears for roughly 3 seconds and then disappears for 3-4 and reappears flickering for 2-3 times sometimes showing the desktop wallpaper between each flicker.
Did anyone experience the same issue?
What I did to try and fix it was:
- tested both on battery and while charging
- factory reseted and then restored backup (which was stupid, that lead me to the second point)
- start in safe mode (to check whether it was an app causing troubles) but no such luck, problem still occurs.
- uninstalled "nice lock" apps
- changed some settings under the always on display tab
- cleared cache of the always on app
What you should know:
- I'm running android 9, not rooted and have nova launcher as default home
- After I factory reseted the phone I wanted to stop always on display from updating to test whether it was a new version issue but I forgot and didn't make it in time so I'm currently running the latest version
Does anyone have any idea as of why it's behaving like this?
edit: just wanna be a little more clear, flickering is not meant like a lightbulb it's more something like it turns off and back on after a delay (I'm sorry english is not my native language I can't really explain it any better)

i also experience the same.
this phone has many strange bugs.
when i restart my A70, tap to show always on display works for me for 2-3 times.
after 2-3 times working correctly, the bug starts.
after i tap the screen, it shows AOD for 2 seconds. then turns the screen off and then at the end of the 10th second, screen just flashes itself for the last time and turns off completely.
i think it is related to the fingerprint scanner.
because after i registered my fingerprints and turned on unlocking the screen by the FP reader, this bug ends.
after i tap the screen it shows both the clock and fingerprint icon at the bottom of the screen.
after 2 seconds fingerprint icon disappears. and the clock is continued to be shown until the end of 10th second.
but there is a minor issue, when the fingerprint icon disappears, the AOD screen brightness changes. dims or brighter slightly.
can you please try tap to show AOD, by enabling the fingerprint unlocking?
samsung ?

Hey! Thanks for the answer, I can confirm we have the exact same issue. I also have the same brightness issue you described
Anyway, I have always used fingerprint unlock though so I don't know what to answer you.. I only recently noticed the weird behavior. I did a couple things to test and I found out that enabling the "fingerprint" icon showing in the always on display seems to "fix" the issue of the flicker but not the one of the brightness change (after enabling it i've yet to see the problem occur), you should try it and let me know if you see any improvement. It's probably on samsung's end though and hopefully we get it fixed with android 10 or earlier
I'll take this chance to ask you another question; two weeks ago I received a software update and ever since that day I noticed my battery to be lasting waaaay less than it used to, did you update your phone as well? Did you notice a battery drain?
I have the issue both of you talking about.
hello, I had this same issue and what I did was turn the phone off, and booting it up while pressing "Volume Up", after entering a black screen with many options, I selected wipe cache. It has worked without a flaw since then. There's lots of bugs with this phone. I recently had a problem where the USB port will detect a device and "plugged and unplugged" it, making my phone unable to dim. Thankfully I was helpful.
