This is very odd and it has happened for no reason. In preparation for unlocking the bootloader, I setup my backup password in Developer Options so I could do adb backup and backup my data. However, RIGHT after I set my new password and got the "!!! New backup password !!!" notification, the screen started flashing bright colors (red, purple, yellow, etc) whenever I touched it. It doesn't feel hot, so I don't think it's overheating, and I've tried turning the phone on and off with no success.
What happened and what should I do? Keep in mind this is a One X with a still-locked bootloader so it's not rooted.
edit: Fixed with help from another user! I don't even remember checking it, but unchecking "Show screen updates" fixed it for me.
Cos you hit 'show screen updates' button in development settings.
Edit... To late lol
I'm curious if anyone else has had this issue. I have to enable a PIN or pattern lock to allow a corporate secure wifi network setting to be saved and for something else (I think for my bank app). From the G4 settings it seems like you can set it to NOT lock when turning off with power button (last option), and a 30 minute timeout before it auto-locks. Yet despite that, mine still seems to lock requiring a pattern input and not just a swipe if I leave it on the table for just a minute. What am I missing?
Thanks all!

These settings are under Lockscreen. Right at the end. It should work, unless you have another app controlling locking.
Exactly.. it "should work"... but it isn't. It insist on locking all the time.. Could the fact that I"m connected to said secure WIFI cause that?? (vs just having an entry for it)
You could try going under the setting for Security - Phone administrators. Look if there is something that is controlling phone lock.
I know for my example, I must enable PIN locking, but my phone administrator for that account enables up to 30 minutes before forcing lock. So as long as I uncheck the setting for "Lock phone immediately on power button," my phone will immediately be unlocked within a 30 minute window where I don't need to enter my PIN.

Right, that's what I'm going for / expecting. I have 3 in there, Android Device Manager, Support & Protection (Verizon thing it looks like) and AirDroid. Only Android Device Managers is checked ON. ADM can obviously affect the lock screen and can change the lock password, but I don't see anything else which would affect this timeout being ignored. hmmmm
(Thanks, BTW!)
I was looking at my Smart Lock section and read the blurb about On-body detection, which was the only Smart Lock I had enabled. It says "Just unlock once and your device stays unlocked as long as you keep holding your device or carry it on you." .... "Your device will lock when it detects that it's been set down"..!! So, I've now turned on-body detection OFF as, in this case, it's working against me. Seems it's not too well integrated with the other options (ignores the Security Lock Timer).
If I don't post back, it's probably working as hoped.
Disabling on-body detection has definitely solved my issue with the G4 locking shortly after setting it down on the desk.
SOLVED
Hi all.
I keep having issues with screen unlock.
First it would only unlock via fingerprint and not using pin.
To test a little i then selected pattern + fingerprint and now it doesn't require either except on first boot up. I can simply swipe to unlock. However, if I scan a non registered finger it says "no match".
I'm not connected to trusted devices...
Any ideas what causes this behaviour? It shouldn't be due to removing stock bloatware, right (Samsung, Google, FB apps)?
Many thanks!
It sounds to me like you have one of the "Smart Lock" settings enabled. These override the pattern and fingerprint settings when specific conditions are met: the device is on your body, the device is at home, or the device is within range of your smartwatch.
They should really be called "Smart Unlock" settings. You can find these settings under "Lock screen > Secure lock settings".
Sort of an old thread, but I'm also facing issues with the unlock screen lag. Somehow it is related to the battery saving: since it slows down the CPU, apparently the system doesn't have time to "process" the unlock pattern (or PIN, same problem; and hang me if that process should take longer than a couple nanoseconds), and the screen goes back to black before the unlock is successful. As a temporary workaround, I've disabled battery saving, and now at least I can unlock with pattern or PIN. But the real problem must reside somewhere else. It's not acceptable that an operating system takes that long in processing the unlock.
As the header says...
I use glasses, so...
I do not use any face recognition anymore but use my Lametric clock bluetooth to "smart" unlock.
Other smart unlocks do not seem to work properly; like trusted places.
Same with my note 9. Says it's not connected. ("Can't add device, be sure...") Yes I am sure it's nearby and it's paired
Voice unlock works reasonable but starts up the assistent.
If anybody has a hint to use other smart unlocking tools..
I use Google Wif
Idem Automateit.

Pfff how I miss the finger....
In order to get rid of the "Touch input is blocked" message you have to disable a display setting.
Open your device settings and go to the 'Display' menu. Scroll down a bit under 'Display' and find the setting that says 'Block accidental touches'. Disable that toggle and you shuold no longer see the message.
Pfff, that did it. some people know everything.
Thanks a lot!

I got this message in Note 9 and compared to behaviour of my wife's Note 9 whose phone was ok and found what's causing it.
Block accidental touches toggle made no difference for me.
Go to Accessibility then Dexterity and interaction and check if option for easy screen on is on. If it is, turn it off. Then it works as supposed.
In my case with this feature on, after covering the sensor, my screen would come on after about 30 seconds with said error. With it off, it turns off completely as I remember on my Note 8.
Hi, I previously had my lock screen set to none, and I loved it.
But since doing a Factory Reset, I no longer have the option to set my lock screen to None.
The only options are Swipe, Pattern, PIN, Password, Intelligent Scan, Face & Iris.
Does anyone have any idea how I can entirely disable the lock screen?
Thanks
In Settings -> Lock Screen the right hand side are the following options:
Swipe
Pattern
PIN
Password
None
then biometrics options. You do not have the None option in the list? However, I see I have a software update to install. I will install and see what happens to the options but looks like it is only the Dec 1 2018 security patch.
---------- Post added at 08:49 PM ---------- Previous post was at 08:30 PM ----------
Looks like they may have added a menu. Now I have to go to Settings -> Lock Screen -> Lock Screen Type
but I see the same menu items
Swipe
Pattern
PIN
Pattern
Password
None
I don't have the 'none' option
I had already installed the software update, but continued to have a 'none' lock screen, until I did a Factory Reset

install Goodlock from Samsung App Store, then you can set the lock screen to set to none! if Goodlock is not on the Samsung app store, as it's not available in all regions just download the GoodLock APK!

Right, but your "Swipe" setting shows No security. Perhaps they moved the setting into there? What do you see when you click on Swipe?
Edit to add: Can you hit the About Tablet on the bottom left and what is there?

When I select 'Swipe' it just takes me back to the previous screen --> Clock Style, Roaming Clock, FaceWidgets, Contact Information, Notifications & App shortcuts.
About Tablet just has my Model number, Serial number, IMEI, Status, Legal info, Software info & Battery info.

Hi, thanks for your reply. I already have Good Lock 2018 (& LockStar). It too has no option for 'none' Lock Screen. When I select Unlock Type, I just get Swipe, Swipe up, Swipe down, Swipe left & Swipe Right.
Thanks for your help guys but I'm pretty sure Samsung have disabled this in the latest software update, I think I'll just roll-back to the previous version, since I really hate the Lock Screen!
I was just really hoping someone might know which system app to disable to get rid of the Lock Screen.

Hi! After digging around a bit I have found reports that point to 3 possible reasons for your plight:
1. Admin apps
2. Credentials
3. Encryption
For the first 2, got to "Settings" -> "Biometrics and security" -> "Other security settings". There you will find "Device admin apps" and "Clear credentials".
The first will basically list apps/software that enforce certain security settings (eg Outook), the second will allow you to remove all certificates, where some of those might also enforce cetain security settings.
The third option is "Encrypt SD Card", found under "Biometrics and security". Some users reportet that it would also enforce lockscree security.
While these may be worth a try, I honestly I couldn't imagine why one of these reasons might trigger after a factory reset. Rather the reset should have removed any of those. This being said, I am on ARK4, have reset for rooting etc and still have the "None" option.
Perhaps enabling the developer settings ("Settings"-> "About tablet" -> "Software information" -> tap "Build number" 9 times or so) would help?

Hi Sokraates,
Thanks so much for looking into this for me.
The only Device admin app that I had enabled was Nova Launcher (for double tap to turn screen off). Never the less, I tried disabling it and rebooting, but I still didn't have 'none' lock screen.
I also tried Clear credentials then rebooting, unfortunately, no sucess with that either.
And I don't have an SD card, so no change there.
I did already have Developer options enabled, with the only settings changed being Window animation scale, Transition animation scale & Animator duration scale, each set to .5x - so I tried disabling Developer options and rebooting, though, alas, still no joy.
My ROM version is ARJ2 which, curiously, is not listed on sammobile[dot]com, though there is an ARJ3 there. I just manually checked for new OTA update and found that I have ARK4 available to download...I just installed it but still don't have 'none' lock screen
I did another Factory Reset with the hope that somehow Samsung Smart Switch had disabled the 'none' lock screen option, when I used it to restore Apps and Settings after the previous reset, but still no luck
I've now concluded that Samsung really must have disabled 'none' lock screen in these updates, at least in Australia. So I'm going to try to roll back to previous versions of the ROM with ODIN...
I wasn't able to install ARGH, with error message "SW REV FAIL : [abl]Fused 2 > Binary 1"
But I could install ARJ3....but still no 'none' lock acreen, arrgh!!!
So now I'm thinking of trying the ARJ3 ROM for other [English speaking] regions, but I'm hesitant as I'm not sure if that will cause any problems???
Kind regards

It's the stupid Security Policy Updates
Update...
I ended up trying several different regions with no luck
I just happened to get a new phone today 'Samsung Galaxy Note9' and one of the first things I did was to set lock screen to none...
But as soon as I connected to the internet, a Security Policy Update was downloaded and applied
My lock screen is still set to none, but the 'none' option has been removed from the list of lock screen types.
So if I were to change to swipe, I wouldn't be able to change back to none.
I've since discovered I can stop Security Policies from updating, but I can't find a way to clear ones already applied
And clearly, neither factory reset, nor clean flash, wipes the security policy updates.
Does wiping Dalvik Cache clear Security Policy Updates??
