No more Secure Startup? - Samsung Galaxy S10+ Questions & Answers

...the one to require your PIN after rebooting your device. Is there a similar setting? I have had this on all my Samsung phone, when available.
Surprise they got rid of something like that.

I was thinking the same thing. Been using it on my Note 8. I think it's a really good feature, except for when the phone applies updates at night and then I oversleep because there's no alarm

Screen stays on after notification recieved.....

What am I doin wrong ? Time out is set at 15 sec.
EDIT: Solved by using different SMS app. Email app works fine
nope.....email works, sms works, not missed call keeps phone awake all the time....
am i the only one ?
I had this problem... Had to reboot the phone.
I have noticed times when my screen was on. When I tried to determine why it seemed that I had received a mms over two minutes prior. My screen timeout is thirty seconds. I have since rebooted and will see if it makes a difference.
Sent from my SGH-T959 using XDA App
I've rebooted numerous times since I've gotten the phone. I prefer the stock messaging app and don't want to *have to* use something else to make it work right.
Any other ideas?
Looks like this is one of the bugs on the phone.....
Thank god all bugs are software related so far. With nexus it wad mostly hardware/software things
I think I figured it out (at least for me)...
I disabled the "puzzle lock" thinking it would be a pain in the neck when trying to unlock the screen. Come to find out, disabling it is what is leaving the display on when receiving a text. Enabled the puzzle lock, and the display comes on for a sec or two and then shuts off when I get a message.
I prefer very few steps to get where I wanna go. I don't like passwords or codes when unlocking my screen so I disabled it. Either way, though, I have swype the screen to unlock it so it's not a big deal to have the puzzle lock on...

[Q] Privacy issues on hd mini

I noticed that when I boot up my mini and I don't insert my code, I can still use my phone. As in browsing through my emails, sms, foto's, files, etc.
The code's only function seems to be making the connection with a network.
Is this a flaw on htc's side or is something not right with my phone?
PIN protects only your phone line.
You could enable the device lock, I believe setting a time out of 0 minutes forces you to input your chosen password when you turn the phone on. This means you'll then have two passwords/PINs to enter each time you soft reset (assuming you keep your SIM's PIN enabled), but if you're concerned about privacy, it is an idea. You may also want to consider encrypting your microSD card.
Excuse me butting in to a non-familiar sub-forum, I was attempting to find the wiki page for this device, attempting to help someone buy their first smartphone.
yeah i tried that, but then it asks you for a code everytime you unlock our device as well and that becomes a pain very quickly
It's not that this bothers me that much, I just think it's strange the phone's protection is this weak
If it didn't ask you to enter the PIN when you unlock your device or use ActiveSync/Windows Mobile Device Centre, then your data would be at risk if the phone was stolen whilst it was turned on. I see where you're coming from (I've stopped using device lock for this very reason), however all the HTC devices I've owned have behaved this way, possible it is a Windows Mobile behaviour?

Not a WinMo problem. This is specifically an HTC problem.
The WinMo locking feature is supposed to be able to set time criteria. For example, set it to 4 hours. When you boot up your phone, it goes to ask the password once. Then it won't be asking it anymore until you reboot your phone again, or until you didn't move your phone for straight 4 hours. You can set different number of hours for this effect.
All my other WinMo phones from 5.0 to 6.x does this thing perfectly. Only my first HTC unit, this HD mini, won't allow this simple feature to work correctly as intended. HTC somehow tweaked this basic WinMo feature, and broke it. So now, if you enable the lock feature, it ask for password each time you come out of standby, no matter what situation, no matter how long or short your phone was on standby. Very annoying. Making it useless.

Yeah sometimes you wonder how did they screw it up so much ?
I really think its better to build a Rom from scratch, I also miss the normal functioning windows start menu. They crippled so much... its almost pathetic...
HTC screwed up many of those simple and beautiful stock WinMo apps, features, and configurations. Not just this one.
I don't really get why they did this. Maybe to discourage you from using stock WinMo apps? Or maybe they're just plain dumb dumb and dumber?
Ah, now I understand the problem. Have you tried other locked apps? CHT's version / S2U2 etc. ?
I don't know exactly what you mean by using other apps, but if your question is if I can use apps or shells without entering my PIN my answer is yes.
If you were aiming at the unlock code popping up everytime I put my phone on standby, it's a hardware button so apps don't affect it I guess

you can still use the normal windows start menu, just disable sense in the settings
it makes your phone a hell of a lot faster and although it's not that spectacular to look at, it's much more functional than sense
i've been using spb mobile shell since a few weeks after i bought my mini and it's made my phone a lot nicer to use.

After Power ON, MUST use Knock Code first instead of fingerprint?

Anyone else seeing this behavior? On my 995, whenever I restart, or power on my phone.. I have to use the Knock Code to get into my phone, and it says "fingerprints unavailable for use" or something to that effect.
I find this odd behavior.
Its not odd behavior its LG behavior.
Unfortunately there's no way around it.
turn off secure startup in security...
Your fingerprint is encrypted and you phone can't access encrypted data until you unlock it after a reboot. So its kinda a catch 22 where you will always have to unlock with a pin after startup instead of fingerprint. Your fingerprint is biometric data and obviously can't be changed so it needs to more secure on your phone than your pin which you can change. It is this way on most phones with fingerprint readers.

It's not just LG, my Samsung S7 and Note 7 both required pin code on first log in after a reboot/boot up
It's part of Android now.

It's not even Android. My work phone is an iPhone and it has the same behavior. Which drives me nuts because our work phones require us to change pin codes every couple of months and we can't recycle codes.
I turned off secure startup as I don't need kids messing with my phone and I imagine after ten attempts if wipes it?

If I'm right, the op is taking about setting the fingerprint to unlock but it still requires the pattern. You will notice this if you use a third party app or launcher to lock screen. E.g. Nova launcher double tap to lock screen. It will tell you fingerprint is unavailable.
A work around to this is to doubly tap the top part of the screen (the bar where the date and signal strength is).
This will allow you to unlock with fingerprint.
If you use the stock lg launcher then double tapping anywhere on screen shows you to unlock using fingerprint.

I'm working with a developer of Screen Lock Pro to try and find a workaround for this. Currently his app will work on Android 5 and 6 by delaying the lock for 5-10 seconds but it's currently not working on Android 7 on LG (it is working on Pixel and Nexus devices).
Hmmm... Not sure I understand this behavior. My fingerprint is much more complex than a 4-digit code that can eventually be brute-forced (phone wipe or not - in theory I mean).. so why wouldn't my fingerprint be the top-most factor in unlocking the phone? I mean.. say I'm one of those guys that uses his last four of an SSN like an idiot, and someone knows that about me.. boom, they're in my phone. Do iPhones do this for real (as stated above)?

Yup, every time I restart my iPhone, it asks for my pin number and the finger print reader is inoperable. Even when I don't restart my iPhone for a while, it will occasionally lock out the reader and require a pin to wake.

Had to figure out where in the menus to dig through to find out who it is. (I seriously do not like how Apple sets their phones up.) Looks like it is AWMDM.

I always assume as much. Not really a bother for me. The iPhone is a work phone that I don't like carrying or touching. My personal phone is always my go to for anything unless it is work related.
I have this on my nexus 6p also. When ever i reboot the phone it requires me to use my pattern to unlock. It's a "feature" of sorts. Not going to go into my thoughts as to why but i think i may understand why they did that.
In case anyone is wondering, a few conditions that force you to use backup method are being left alone (with no smart locks enabled or active) for 4 hours, a reboot, and a failed scan 5 times in a row.
The reboot case is due to encrypted data (no matter what you do, your phone is encrypted on boot, unless you fix that, however, you phone will still treat it as such). The only reason I can imagine for the time out is in case a ninja chops off your fingers in your sleep. As for the wrong input, that seems annoying sure, but odds are if you got the fingerprint wrong 5 times in a row, it's not you.
Yeah v10 does this as well on fresh boot ups.
I'm not sure I understand the reason behind it I would think it would be less secure this way.

I'm not sure I'm following as to why encryption matters. Are you saying my fingerprint data is encrypted? If so, why isn't my PIN also encrypted?
Speaking of fingerprints has anyone run into the issue where the phone "forgets" your print? I have had this happen at random times and while the fingerprint data is still saved the phone fails to recognize my finger so I have to set it up again.

Is there any good Anti-Theft? (Does Cerberus to system app make any sense?)

Hey there,
my Lenovo P2 recently got stolen and now that I've ordered a used S8 I am looking into ways to protect against theft. And frankly I don't see a good way.
The most obvious thing a thief will do is to shut down the phone and throw away the sim card, so I looked for ways to defend against that. You can't deactivate the force shutdown by holding the power button for 10 sec, which sucks, but the Cerberus app can do a pretend shutdown, which is at least something.
But what about removing the sim card? Without sim card there is no internet connection and therefore no tracking app will work. And once there is no tracking the thief has all the time in the world to find a way to reset your phone and bypass SFR. Well, nothing you can do about that.
But can you defend against a factory reset? Make Cerberus a system app and it works even after a reset! Sounds great, I thought! BUT, in order to do just that you have to root your phone, meaning unlocking the bootloader, meaning the thief can just flash your entire phone through the bootloader. He might not, but he can. Making all the work in rooting and preparing pretty useless if it's not even secure.
So I'm asking, is there any way to secure against theft? I have the idea of making the phone ring when it looses connection to my bluetooth headphones, but that can backfire so easily...
I'm open for any ideas. Hope there is something out there I've missed.
same question!!
1. You have to input pattern/password if you would like to power off the device locked.
2. As far from what I've seen with my friend's S7 Edge, you will need to sign in with your google account if you forced factory reset it in recovery not sure about odin flashing.
3. I'm not sure about this but as long as Location is turned on it can still be tracked even without an internet connection. Again, I'm not sure but I think iPhones have this feature so maybe it can be done on Android too.
Hope the little infos help. Cheers
I've had the Cerberus app since my Nexus 5 days and it's pretty useful.
Regarding shutting down my s8 by holding the power button, Cerberus just does the fake shutdown screen off thing. Also there's an option in Cerberus to disable the power menu when on the lockscreen, which I have enabled. I think the only way to actually shut down my s8 from the lockscreen is for the battery to die on it's own
As for the data and sim card, the app recognizes the original sim card. So if someone puts in a different sim card, the app sends a notification to your email or spouses phone. I think it sends location data too but I'm not sure. And data is accessed thru any sim card. My phone WiFi is set to on all the time anyways so Cerberus will look for any open network and communicate thru that. However, the pull down menu is still accessible in the lockscreen. But on the s8, there's a setting to lock the pulldown menu buttons so u wanna make sure that's turned on.
And for defending against hard resets, like i mentioned earlier the phones power menu is blocked, so they won't be able to start the process until the battery dies by itself

between cerebrus stock security factory reset protection and such you can locate and such but best wepon is imei
Write it down if all else fails report the imei to your carrier and have it blacklisted also....
I also use my gear s2 watch as the have a find phone/watch setup too.In the end A thief will do what it takes and can bypass most if not all security implemented by google or others best you can do is take all the precautions and be ready to pounce if its gone....
I've been using Cerberus for a couple of years now.
Had it installed on my S6 when it was "stolen" of my desk at the office one evening when we were working late.
I tracked the culprit in real time as he and his wife were driving on the highway 80km away.
While they were driving I took snapshots and listened to their conversations.
Luckily (for him) it was all just a mistake, he had a S6 too and merely took mine by mistake.
He gave it back the next day.
Still, IMHO, Cerberus is well worth the cost.
Protect against Flash
Since you have been using it by sometime do you have any protection agains flashing a new ROM ? Did you make a new partition or something ? Is there a tutorial ?
Thank you !

The only protection is the fake shutdown.
Thief thinks he shut down the phone meanwhile it's recording video.
Installing is straight forward. No partitioning required.

Alarm not going off after reboot

US unlocked S10+ (ASBA) set up alarm, restart phone, alarm did not go off; after unlocking phone the first time after restart, set up another alarm, restart phone, and still did not go off.
I recorded the test here: https://youtu.be/CvMrJtrOrzo
U need to unlock from lockscreen to finish up the booting process. Sucks I know I figured that out the first time it happened. It's some Knox bull**** to protect u after a restart. You turn it off I think under strong protection in settings.
Edit... I ran a test and like u it failed and then I went and turned off strong protection and redid a alarm and restarted and it works. Its stupid honestly but it says calls, messages and alarms still work while it's on after a reboot.
You're right, I tested the same thing under similar conditions and the alarm is completely ignored, I uploaded the screenshot where it is said that calls and alarms will still get through, but that's bull****.
A bug of this kind is unacceptable, most people rely on their phones to start their schedule in time and this makes your phone as useful as a brick.
I reported the bug to Samsung, meanwhile you can allow calls and apps to automatically be active by disabling Strong Protection in settings, Biometrics and Security, other security settings.
I tested it as I'm typing and it works.

I wouldn't call it useless as a brick, but definitely not feeling reliable (just like iPhone and DST, but at least that's only twice a year). I am pretty sure it is the Clock app misbehaving, because uninstalling the update the alarm went through fine after restart.

It's useless if it keeps me sleeping at home from paying for it
It's the clock app not being given the right priority, it is denied access to user data like every other user application.
Make sure you report it through the members app
