Need help with troubleshooting display issue - Samsung Galaxy Note 8 Questions and Answers

Hello,
I am getting grainy display(refer attached screenshot) in note 8 but the touch seems to work fine, i am able to wakeup display by double tapping it. i want to know if this is a prob with faulty display or software corrupt issue. This is happened all of sudden when i was using the phone.
I was able to unlock the phone twice by entering the pin by guessing the position of numbers and then when i move the s pen vertically it clears out the grains and shows the home screen, i was able to access settings option but i was not able to access app drawer nor change settings like remove security nor enable usb debugging(i was able to get into the developer options but when i click on the enable usb debugging its not responding for few secs and not enabling the option).
Any help to figure what is happening is much appreciated.
Regards,
jj

I assumed under Settings > Controls > S Pen, all of your settings are not configured to "Off"? Are you rooted and may have frozen something or tweaked something to prevent this?
Past software, it could be a hardware sensor on your device where the S Pen enters - I would try changing the tip of your pin (you should've gotten extra tips and a a tweezers tool for removal) and see if that makes a difference.

Lock Screen Fingerprint Unlock

I have my lock screen set for fingerprint. If the device is shutdown or restarted, the lockscreen asks for a fingerprint. After that if the power button is pressed to shut off and lock the screen, the next time it is turned on the lockscreen asks for just a swipe. It wont ask for a fingerpring again until the system is restarted again. Anyone else have this problem? Solutions?
You have to go into settings and set the power button to lock device. Or you can change the settings to lock device after a certain period of time.
It's under Lockscreen/Secure Lock Settings

You can also set it to not lock if it's connected to a certain device, like a Bluetooth.
This is a god sent because it's always been a pain to unlock the phone in a car after it's gone to sleep and you are streaming music from it.
Thanks! That was driving me crazy. I knew it was there, but couldn't find it.
I know what you mean! It was confusing the heck out of me in the beginning but then caught on.
How do one wish to switch back to just a simple swipe after choosing fingerprint unlock
The SWIPE option is now greyed out ??

Phone is automatically bypassing lockscreen randomly

I'm running lmy48i rooted. Project fi the whole time.
My phone is randomly, not duplicatably, unlocking itself in my pocket, or as I'm holding it. It's not a power button issue, as much as i want it to be. Ambient display is off
I've pulled the phone from my pocket with it unlocked in camera mode, having taken numerous pictures, no on screen buttons working because it's not "unlocked". I've picked up my phone and it unlock itself straight to the home screen, with a good 5 second lag before the lockscreen kicks in.
This happens with a pin code lock also.
I don't want to have to factory reset, as I'd rather pinpoint the problem in case it is indeed something I've done, so i don't replicate it after a reset and still have the problem.
Anybody have any ideas what i could look at for this? It's not always been this way, but it's so random, i can't pinpoint any changes or programs that i have that would be causing it.
I've searched my heart out, but all my searches come up with other related things and I've not seen any one with this specific issue

Settings -> Security -> Smart Lock -> enter your pin -> On-body detection -> turn that crap off.
Personally, I use Trusted devices (BT smartwatch,) and can understand Trusted places. But I don't know who'd want to keep their device unlocked when it's being carried around, possibly by a thief.
Tried that also. I tried toggling it on for a while then back off to see if maybe that'd jog some setting, but it hasn't fixed the issue.
I've even disabled smart lock altogether to see if that would work, and it hasn't.
Edit
I've only recently enabled pin lock to make sure i wasn't in fact leg-unlocking my phone through my pants. But enabling pin lock, smart unlock or not, hasn't changed the situation.

Accessing that area can be done on Samsung devices aswell. This is not a security flaw, that area is meant to be accessible from lock screen so if you need to turn flashlight on or similar things without needing to unlock your device.
But if you pick some of the buttons it will request you to unlock the device to do the action. Only some of the buttons can be used while on lock screen.
On Samsung if you touch WiFi, Bluetooth, mobile data and position tracking on lock screen it will then request you to unlock the device to be able to turn them off or on.
After checking my Asus Rog phone 2 I see what you mean now. It seems Asus didn't add such security, which they should.

yes asus keep every things accessible so if someone stole ur phone in 3 sec the phone will be in offline mode and lost for ever
in my Huawei they totally block using the above scroll bar and add some useful shortcuts on lock screen for flash and so on

N950U can't pull down notification

Hello, Suddenly my status bar area is not responsive to touch therefore I am not able to pull down notification. Touch is working perfectly on other areas.
I tested touch using *#0*# and top area blocks are not responding to touch.
I didn't dropped my phone, screen is not broken and no water damage. It suddenly stopped working.
I tried reboot, safe mode, wipe cache partition and factory reset but it is not working.
Initially i thought it is hardware issue but in lock screen i am able to pull down notification perfectly. so hardware issue is ruled out.
Can anyone recommend a solution? Your help will be highly appreciated.

It could very well be hardware related and there's no other way but to replace the screen if it is indeed hardware related... But for now try going into settings -> display -> status bar -> untick and retick both options there and see what happens.. I was also going to suggest to try this.. Press the physical power button until the power menu appears
Long press the on screen power off button until it turns into 'safe mode'. Click on that
Check whether the status bar now works or not. If it works, then it's definitely related to one of your apps possibly.
But you did say you tried safe mode so I don't know.. Have you updated it recently? Any recently installed apps?
Edit: Do you happen to have a screen protector and case on the phone? Someone else said quote. "the glass from the screen protector was interfering with the perimeter of the plastic case. The plastic pushed the glass up, so thats why it was interfering."
Let me know.
