Random Padlock icon while on DEX Mode - Samsung Galaxy Note 8 Questions and Answers

Hello everyone, there is a random Unlocked Padlock icon with a color circle rotating around it (its the same padlock icon and rotating circle around it as when i restart my phone and its asking me to enter my pin number because my phone is encrypted) showing up on my TV screen while i am using the phone on DEX mode. When it shows up, its there for a couple of seconds, then it goes away and my phone's lock screen shows up in "screen mirroring" and then DEX mode starts again and the phone functions completely normally until it does it again which might not be for hours.
I have cleared system cache like 5 times. No change.
Unlocked Note 8 U950N on Verizon
Not Modified in any way, Android 8.0, Latest security patch (same issue with previous security patches)
OEM Samsung DEX Station
Bluetooth Keyboard/Mouse
1080 resolution
OEM Charger
Things to consider: 1- My S pen sandomly stops working. Tried a new Spen and it still work work, no hover circle or any input from the pen. restarting the phone fixes that issue.
2- Phone will randomly show "slow charging" when first plugged in to the OEM charger and wire (have 3 different set and it does it will all of them). Unplugging it from the phone side and plugging it back in fixes it.
Please let me know what you think for all 3 issues before i contact samsung for a warranty repair/replacement.
Thank you

Touch problems while charging

Hello all,
I have strange problems while charging (wall charging only) my NOOKcolor: the touch screen is not responsive (either at all or very sluggish). On home screen I could launch programs, but not rearrange (drag), have to type very slow in order to get input, on lock screen cannot even unlock
If disconnecting the charger (from wall or cable from nook) it starts to work perfect.
My NOOKcolor is fully rooted, but the problem remains after un-root/factory rest.
Anyone else seen this behavior?
Any solution/suggestion?
Thanks,
Darky
Your problem is not unique and has been noted by many others. No fix was discussed yet though.
Mine doesn't do it. I saw on google it's one of the possible problems with a new unit. You might want to reflash to stock and exchange it.
I've noticed mine does it while playing Pocket Legends. If I have it on the charger, it will automatically tap-click on the screen when I'm using the joystick, so it starts to open all sorts of menus. So I pretty much can't play the game when charging.

Galaxy Note 2 - Snowy Screen when launching Android Auto

Figured I would post about my issue. I just bought a 2017 Hyundai Elantra. I tried connecting my Galaxy Note 2 to it using the USB cable provided with my phone. Once I run the App, the screen of the car shows nothing but fuzzy white snow (like the old analog TVs showed when there was no reception from the antenna), and then the snow pauses after a second. If I touch the car's screen, it reacts to my input by the snow moving again until I stop touching it.
I was first trying to connect with a CM12 Tesla build (Lollipop). I then flashed my phone with Resurrection Remix 5.6.4 (Marshmallow) and got the same thing. I've tried many tricks I've read from others who had blank screens (not snow, haven't seen anyone report that). I've also played with the Developer options, debug, HDCP and nothing made a difference. I did read that the phone has to be on MTP, but every time I plug it in it switches to USB Charge. If I select MTP after being connected, the screen on my phone refreshes itself (goes totally black for a half second) and goes back to USB charge and the car's stereo goes back to the home screen.
Anyone have any ideas on how to get it to work? Or do I need a new phone?
Same here, have you found any solutions?

Floating Icon For S-Pen Randomly Showing Up

I have this setting turned off. It's been off since the day I got the phone in the mail but suddenly I'm starting to see the floating icon pop up. It's random. It doesn't happen when I pull the S-Pen out but I'll just have my S-Pen sitting next to my phone (outside the phone) on my office desk like I usually do, then I'll start using an app and suddenly I see the floating icon pop its head. I'll touch it then touch away from it on the screen and it disappears.
But it's randomly reappearing. Different apps, different times during the day. I've restarted the phone and clean cache here and there and it still doing it. So weird. Has anyone else seen this on their phone?
EDIT: I attached a pic I just now took with my S8 Plus to show you what I'm talking about. I'm in the S-Pen settings and you can clearly see the option for the floating icon is set to OFF yet it's still there on the side and you can see my S-Pen chilling next to the phone on my desk. I touched the icon, then touched away from the screen and it disappeared. I locked the screen, waited a few seconds, turned the screen back on and the floating icon reappeared.
Something is funky. I have no idea what's causing this.
I have a cheap Chinese-made leather case with poorly placed magnets that causes this behavior. It became so annoying that I stopped using the case (and the problem went away). Perhaps your problem may be a nearby magnetic field too.
I think the Note 8 is having some teething problems. I want that icon on my front page and have it turned on in the settings but it only shows when it feels like it? I suspect Samsung will address this situation when it updates the Note 8?

Weirdest black screen issue, tried everything ....

Non rooted, T mobile branded 3 month old note 8. No water damange, no drops etc.
Using chrome one miniute, set the phone down to watch a movie on my tablet, picked up the phone to check messages and boom. Screen is off. The phone works, I can even answer calls because I know where the answer button is on the screen, haptic feedback works, all indicator lights work. The phone screen remains off.
Tried a soft reset (tried hard reset too the best I could being I cant see the screen) and the phone seems to reset based on the vibration and indicator light patters but the screen remains off. It's as if a physical connection between the screen and the brains of the phone has been severed. Literaraly the weirdest thing that has happened to me in a decade of Android phone ownership.
Googled all the black screen issues with these phones and most of them are resolved with just a soft reset... some said that the phone is in it's lowest dimmed state and go to a dark room and i'll see it faintly and then can increase brightness... no luck...
Has anyone experienced this?
I would say it's a warranty job, just tried turning my brightness to zero and you can still see the screen.
I did have a similar problem on an old note that had root and custom rom though but I had somehow set the volume rocker to control brightness and it had lowered itself to minimum in my pocket

Try pressing and holding Volume down and power button for 5 to 7 seconds to force power off, then try to boot to download mode Volume Down + Bixby + Power button and see if the download mode screen shows......if not then probably a bad screen.

Tried it......nothing.....warranty job it is.... Bummed to have some refurnished phone in exchange for a Brand new 900 dollar phone just a few months back?

Yeah that sucks, i can imagine..... i too hate the idea of refurbished units being swapped for warranty....bs, should be brand new unit!

so I had it replaced under warranty through T mobile. Refurb phone will come in today. One quesion. Should I let the Tmobile techs do the data/settings transfer from old phone to new one or just do everything myself from scratch (which will obviously take longer).
This happened to my phone twice for the past month or so. (both in Nougat and Oreo - Non rooted) Black screen but phone seems to be responding -- I can receive calls and notifications etc -- And force reboot doesn't fix it. I've also tried drainging the phone when it first happened to me but doesn't work. HOWEVER, it gets okay so randomly. Like I just left it for couple of hours and it just worked when I hit the power button.
I did tried bringing the device to Samsung but what they did is to just manually upgrade/reset the software in their end which I could have done in my part but I just let them do it. They told me to come back if it happens again which is kinda BS.
I can conveniently say this is a Hardware issue. I will wait for it to happen again on my phone and request for a replacement. Phone is 4 months old when it first happened.
I have the same issue with blank screen but phone is working.
It started couple of weeks after i dropped my phone on the ground. There is black dot on my screen and broken glass but phone was working ok and was still pretty usable. But then it started:
Display works fine but when i switch display of, lock the phone or display switched because of its timer it didn come switch on... But phone works, i can use it with blank (black) screen.
I had to do force restart so the display will turn on with samsung logo and booting screen, and keep on till another switch of.
I was trying every setting (but no hard reset) and then i found a little hack:
When you turn on the "Always On Display" (AOD) function you can let the screen switch off or do it manually, wait for 1-2 sec and always on display will come up to the screen. Then when you press home button or lock button screen will swtich on normally. YOu can type pin and use phone witch screen working. But when you try to unlock from "AOD" with your finger or your eyes it unlock but with screen black.
So i was using it like this. everytime you need to wait second untill AOD comes up, but it was working fine.
Problem nu 2 is that now it stop working, AOD is working but when i want to switch screen on from AOD it shows black screen and phone is working on blind.
So everytime after my screen goes black or to AOD i have to unlock the phone blindly and "Force restart" it and have to keep waiting until boot, and then have to never let phone to screen of.
Its not usuable.
¨
Now what do you think? Is it hardware problem or software problem? Because screen is working but randomly. The black dot of dead pixels on the screen is getting slightly bigger in time (about 1 year) but its like 1.5cm round. Maybe this cause the problem? And why hack with AOD was working for half a year and then stoped working? There wasnt any updates right before, but i tried to install some apps (non display related) so ill try to uninstall them.
Hawe you got any idea if i can repair it on my own even if i loose the waterproofability?
Or can it be replaced for free if i have a warranty? (I dont have insurance)
Thanks for your tips guys.

If you're under warranty it will likely be a free repair, unless they find other damage. Like moisture damage.
As far as fixing it yourself, it's just about as cheap to have Samsung do it than it is to buy the parts yourself. It's $229 for Samsung to do it, and you'll maintain the water resistance rating.
same has happened to me

This has just happened to my note 8 too. I was about to update it and had started it. set my phone down and picked it up and phone screen is black but can hear the haptic feedback.
I can only see the lock screen and the notifications. Everytime I try to unlock my phone I only get to see a glimpse of the notescreen and then the screen turns black. Even when I try to go to camera through the lock screen the screen goes black too. When I charge my phone it heats up so I haven't really charged it as well. Has this also happened to anyone? It seems as if the phone's sensitivity still works in all places but when I unlock it the screen just goes black.
I also have problem of freezings and always rebooting. Tried soft and hard resets/factory reset. Still same problem. This phone has hardware issue. Do not buy.
I realize this thread is quite old but I have this exact same issue now. I have managed to discover some other information by playing around with various settings which are noted below. To begin with, I was able to used the AOD hack posted above for a while but it no longer works. The only way I can get my screen to come back is with a soft reset - but as soon as the screen times out or i turn it off, it goes black, with or without AOD enable. All the on screen buttons still work as well as the haptic feedback - I just can't see anything.
Now on to what I have found:
One thing I have found is if I turn off adaptive screen brightness and crank the brightness slider to the right, when it goes black I can faintly see some of the buttons - enough that I can turn the phone off or restart it from the power menu (If I switch the default setting to night that also helps to see the buttons a bit better). Also, if I enable night mode I can also see the brightness slider faintly but when I slide it left, it just makes the screen completely black and when I slide it right, it only returns it to the very faint brightness level.
So at this point I am stuck. To summarize the issue:
1. When the screen either times out or turns off, it is still "alive" but goes black. It will not return to normal brightness.
2. Turning off adaptive brightness and cranking brightness slider to right allows you to see faint buttons after screen times out but won't return to normal brightness.
3. Enabling night mode helps to see the faint buttons, in particular the brightness slider a bit better. However the screen still cannot return to normal brightness.
4. The only way to get the screen back to full brightness (albeit temporarily until the next timeout) is to turn off the phone or reset from the power menu; or soft reset holding volume down + power simultaneously.
Hopefully someone else has figured out a way to recover this. I am on Android 9 with Samsung UI 1.0
Phone is completely stock, never rooted and completely out of warranty.

Always On Display bug?

Hey guys,
So I am using GoodLock Routines and I have this routine that sets AOD to 'always show' mode as long as I am charging my phone and I have it set to 'tap to show' while I am not charging the phone. This used to work perfectly before the OneUI 2.5 update. Now when I plug the phone to charge it and the screen is off and locked the AOD shows up for 1 second but then disappears. Can anyone else try this to confirm if it's an issue with the update or it's just me? I also tried to sideload Bixby Routines but it does exactly the same there as well.
If anyone knows a way to show my lockscreen for 1 second when I plug in my phone to charge that could also be a fix as the bug only happens when I plug my phone to charge with the screen off. If I plug it with the screen on and then lock it the AOD remains on as it should.
PS: I am not rooted and won't root so need a non-root method for the screen wake-up part. I tried Tasker with SecureSettings but it's a hit or miss, 1 time it works, then it doesn't.
