I find it incredible that for a phone with a non-removable battery that you can turn the device off without having to get past the lock screen security. This is a major security flaw in my opinion.
If you were unable to power down at the lockscreen, then if your phone were to be stolen, then at least you would have the time it takes for the battery to eventually die to attempt to track it.
A long-press of the power button at the lockscreen should only be allowed if the lockscreen type is set to none/swipe.
If anyone is in a position to put in requests to Samsung themselves, could you please submit this.
Any further thoughts welcome....
What if you're stuck on your lockscreen, your screen doesn't respond and you have to reboot your phone to solve the problem ? how are you supposed to do if this option is removed ?
Terrible idea you have here
And if there was no way to turn it off from the lockscreen, the stealers would just have to wait until the phone have no battery left, then the phone would be off

A long-long press of the power button (approx 8 seconds) will force a reboot as per all Samsung phones, so if you do have a problem you can then go into recovery (eg. to wipe cache etc.). Ok, the thief might also be aware of this and do a factory reset in recovery straight away, or even keep the phone in recovery until the battery dies, but some may not be aware to do this. And, even if a thief did a reset, then at least your data would be wiped, which is half the battle when a phone is stolen.

But at least you would have the time it takes for the battery to die to track it, which I already stated. So once stolen, you could have anything up to a day to find it again. Currently if someone steals your phone, all they need to do is switch it off immediately, and you will have no chance of ever seeing it again.
A nice firmware feature would also be to send an e-mail to yourself of the phone's current location when battery level reaches a low level (eg. 5%). Some apps (eg. Lookout) have the facility to do this.
As the S7 has a non-removable battery, it should at least have the option to disable the power key menu at a secure lockscreen.
All phones with non removable batteries are like this for the reasons the person stated above. This function is exactly the same as if the phone has a removable battery. If a thief stole an s5 they could just take the battery out immediately and you couldn't track it either... The battery isn't a security feature. It's just to power the phone. They need to have a way to cut the power on devices. This is standard for most electronics. Hold the power button on your laptop and see what happens.

Don't know if you are aware but if you setup and use Samsung's Find My Mobile, you can lock, disable shutdown, and display a message on the screen with a button to call a number of your choice should you lose the phone. Try it out.

Considering the fact that should your device become unresponsive/problematic you can always fall back on a long-long press of the power button at any time, including at the lockscreen, in order to reboot / go into recovery (which is an inherent hardware feature across all Samsung phones), I therefore still believe that allowing a power off at a normal long press at a secured lockscreen prior to passing the lockscreen's checks represents a flaw in your device's security. I think power off (but not reboot) should be omitted at the lockscreen popup and only included when a longpress of the power button is done after the device has been unlocked.
And what makes it worse, you can also pull down the quick panel shortcuts at the lockscreen which would enable a theif to turn off location from there too.
Basically, find my phone type functions are only of any use only if your phone is ever lost, but useless if ever stolen.

It does seem that Samsung have missed a trick with shutdown from the lock screen that could be very simply enacted and give another string to the security bow.
or you can just disable power menu on lockscreen via Gravity box..viola ?

You seem to be missing the whole point. Every phone behaves this way. Whether a removable battery or not. You can disable the power to every fun from every manufacturer at any time no matter what type of battery. It's not a security flaw. Also you can go into settings and disable the notifications from being pulled down before the device is unlocked.

They should make phones with no batteries to fix the battery flaw, powered by air. Working in this field, I've seen a lot of broken and stolen phones come and go, if you really want to remove the battery, it'd take 2 minutes max if you arent worrying about replacing a 10 dollar back glass.
People consider iPhone's battery non-removable too, you can get that thing disconnected in less than a minute. Also there are dongle tools (Can even DIY one) that can force your phone into recovery/download mode simply by plugging it in.
So I think this is just needless worrying.

Hi,
I've had my HTC titan for a few weeks now (since UK launch), and I am having a problem with the phone rebooting itself in my pocket, when I sit down. Now I am pretty sure that this is actually a windows phone bug AKA "Feature", but one that is more evident on the Titan due to it's size.
The problem is that when I sit down and lean forward (e.g. to tie my shoes), the power button gets pressed into my hip and is held down..and then after a few seconds the phone reboots. This is even with the locking enabled and pin protection.
Has anyone else come across this issue? Is there a way to prevent the phone rebooting from a long press of the power button? I am seriously regretting switching over to windows mobile again because of this issue..it's a real pain..I don;t mind if there is an app/mod I can install to fix this if it's not possible via standard settings (something like pShutXP for WM6) ..any ideas at all would be *very* welcome!
Thanks,
Spud/Pete
so, let me get this straight:
1) you want to disable the power button? How would you turn off the phone afterwards?
2) to turn off the phone, you need to slide down the lockscreen, and this is very unlikely to happen
3) if "you are tying your shoes" long enough, this will initiate hard shutdown of the device
So no, no way, carry the phone elsewhere.
Yeah, I'm confused by this too - as of Mango, simply holding down the power button won't ever turn off the phone (though it will show half the lock screen, with a prompt to slide it down fully to turn the phone off). Since the Titan comes with Mango... yeah, confused.
No..I am not talking about turning off the phone - thats completely different as you say, you have to slide down the screen and as its capacitive..that's pretty unlikely to happen in my pocket.
I am talking about the phone rebooting - I can replicate it in my hand by holding down the power button and the phone will reboot itself without touching the screen.
I don't want to disable the power button - I want to disable this reboot on long press functionality..as it's a right pain.
Maybe this is peculiar to the Titan rather than a general WinMob feature..but try it on your mango phone - lock the phone, and hold down the power button for around 10 seconds..don't touch the screen. Does it reboot?
Ideally holding down the button should just show the "slide to turn off" screen and nothing else, there is no need for that kind of hard reboot function when you can take the battery out on these devices..
Suggesting that I just don't have my phone in my pocket is not very helpful tbh- where else should I carry it?
No, my HD7 does not reboot if I hold the power button. I almost wish it would, since if the screen locks up I can't power-cycle the phone without removing the battery.
If there's not anyway to carry the phone such that it doesn't hit the power button (not a problem I have with my HD7, but I've never tried carrying a Titan in my pocket), consider getting a case - many of them can make the power button a little "stiffer" and less likely to be pressed accidentally.
I can confirm the problems Spud1 has!
Just like him i own myself a HTC Titan and with WP7.5 you can reboot the phone even when you don't slide down to shut down the pohone.
And that is VERY VERY annoying, even so much that i almost want to switch back for an android phone...
You can replicate this "feature" bij locking the phone when you push the start button on the top and put the phone in rest. (black screen) Then hold down the start button and do nothing. You get the half"Slide down screen to shut down the phone. Still don't do anything, no sliding, just hold the button. After 6/7seconds the phone wil just reboot!
This happens me also and can be replicated at least also on a HTC Trophy (it just shuts down) i believe it can be replicated on the Samsung omnia7.
This is something were i had contact over by chat and phone with HTC. But they will not help or are in no position to sort this out... A brick wall, and i got dissapointed by service.
I dont know how to get in contact with MS, otherwise i would love to do this!
So people, try it out, en then someone to solve this thing, i would rather pull my battery for a restart than this "feature"
PS. sorry for my typo's as a first post..
I've got this too on my trophy !!!!!
I can confirm this problem also on my Mozart.
It is probably one of the 500 innovations in mango.
Sent from my 7 Mozart using XDA Windows Phone 7 App
Innovations i can understand, but the Titan is an 4,7inch phone.
When you have this in the pocket of your jeans, like 85% of the people does, there is problem with this so called innovation.
And believe me, supportdesk at HTC in the Netherlands make me feel stupid about our complaints. The freaking phone restarts after 6 seconds while sitting on your knees or bend over to tie your shoe's...
Is there anybody over here who knows how to deal with this/disable it or has connections to discuss this problem with HTC or MS?
I can confirm this problem on HTC Trophy too(custom rom)
If i hold down Power button ,slider shows up .If i continue to press Power Button and do nothing my phone is power down (not restart)
It's a standard WP7 behavior, why do all of you complain? It's not a problem but standard feature (to be able to reboot phone if touchscreen stop working). Buy another, not so tight, jeans or belt phone holder or protective case.
Who said i wear tide jeans?
There are also people on a Dutch forum that had problems with some protecting cases or just in a bag. And that was with the Trophy.
I finally love the system itself, but this is a 4.7 inch phone where i payed a lot of money for, so i'm allowed to expect something.
Apparently the Systems features and the size make it a combined "problem".
a lot of people get this problem now and in the future when Sales go up!
BAM., there is nothing what you can do. I think it's by hardware design so there are no registry settings to disable power button. But what you expected is absolutely irrelevant to the current WP7 products
That is a straight forward answer! Until now HTC didn't give a proper explanation..
If it is hardware related, this is the only thing that s#cks on wp7/HTC Titan. But i still don't think so, because other ones, like the trophy just shut down.. No restart!
It just feels so dissapointing... Because i really started to like WP7.
Hopefully there will come a MS answer somewere/sometime for this.
thnx anyway!
Omnia 7 has the same behavior (press and hold makes the scroll down menu appear, keep holding and the device reboots) so it's not restricted to HTC devices.
Fortunately, I tie my shoes really fast
lg quantum here, same thing lol
Confirmed on my HTC Surround, phone shuts down. Also on my Blackberry 8350i (although power button is right below the screen and it comes with a holster so not really an issue). Pretty sure that the Evo Shift I used to have for work would do the same thing.
It's a pretty logical function though. If your phone were to lock up for some reason, there's no soft reset button that you can press. This serves the same function. Try holding down the power button of your PC for a few seconds. You'll find that it does the same thing. When you first press it your computer will (probably) start the shutdown process but if you keep holding it then it goes straight to off.
It's logical for a PC, or maybe even for a device where you cannot remove the battery or there is no other way to reboot the phone if it locks up (but who's to say that this "feature" will even work when the phone locks up anyway..)
But for a mobile phone where the power button can easily be pressed accidentally, where a device has to deal with much more than just sitting on a desk..no that is just poor design.
I understand that for many people it won't be an issue - but the fact remains that for lots of us it is (it's good to see that it's not just me!)...and calling it a "feature" doesn't help (thats a long running trick in the software trade..many features are just bugs/poor design disguised as such!).
I suspect that to fix this problem we are going to have to wait for a full unlock for HTC mango devices, so that we can load native apps who can potentially resolve the problem. I don't know enough about WM7 development yet to know if you can get at the Hardware Interrupts or not but if we can do that, then I am sure we can fix it. It's possible there will be some registry/configuration options too buried deep in the system, but without the interop-unlock we're stuck I think..
HTC/MS support sure as hell won't help us out as it's definitely going to be called a feature, no matter how big of an annoyance it is.
This combined with the discovery of how terrible Bing searching is has really put me off Windows Phone 7 though (the terrible search is the worst thing)..I'll be jumping back to iPhone next yearwhen Apple release their redesigned one, can't see a reason not to anymore. Which is a shame as I love the device + UI
Spud1, the long power button press can be handled by hardware schematics, not a firmware or drivers (but actually I don't know exactly, of course). So, your hope is very weak...
True it can - but you could override this kind of behaviour in WM 6.x..and WP7 is still just windows CE with a layer over the top really, so there is a good chance that it's doable.
The thing that makes me think it's possible is that people who have upgraded their devices to Mango from NoDo seem to have the same issue - which leads me to believe that it's partly to do with Mango rather than down to specific devices..but to be sure more people who have those kind of devices (and particularly those without a HTC device) need to read this thread and reply
I would rather have a better explanation (if there is a better one) then what I'm about to say as I'm planning on returning the phone and getting something else.
I went to unlock the phone, but upon pressing the power button instead of being presented with the lock screen, I heard the sound the phone usually makes when the phone is locked/unlocked and after that the phone wouldn't respond to the power button and the volume buttons would only light up the 'buttons' underneath the screen, so I pulled out the battery which did clear the problem but the battery charge had dropped to 52% from around 90% (in the battery use details for Android OS the keep awake details shows a duration of 2h 14m 37s which might be something to do with this problem as I don't think I've seen that part show any duration since I got it which is only a few weeks) and a few minutes later it stopped responding to the power button when locked again (which has prompted my returning the phone to where I got it from since I can't trust it to be reliable now).
Something else I need to ask is about backing up data for specific apps I've been using (none of which should have caused this problem to happen) as restoring data for one of them is likely to be a pain to do.
Can I just transfer the apps to the SD card (which I already have in the phone, and does contain some data for one of the apps) and put the SD card into the new phone when I get it, or is it going to be more complicated?
? have you solved?
Now this doesn't happen all the time every time, but usually around a notification and the screen is off, I go to hit a button to turn on the phone and it doesn't respond but the touch-keys are backlit. If Always-on Display is on, the screen is black regardless, not even showing the time or notifications. The only fix is waiting ~10 seconds for the phone to respond, which in some cases can be the difference between a missed call.
Now, seeing Always On Display off like that while it should be on made me think back to when I saw some sort of Nougat optimization setting that allowed me to select Always On Display, and as far as I remember, I did. That makes me think this process is killing AoD and it is taking that long to start back up, where the phone won't unlock until AoD (is back on and) can confirm that it's trying to wake up out of that state.
However, I don't believe this is the issue. I have turned off AoD and the issue still happened directly afterward, after a Messenger notification. This is stock firmware, however it is not factory firmware. I believe I downloaded it from Sam-Mobile, and they had the 7.0 Nougat upgrade that I would have gotten OTA with the factory firmware anyway.
Somehow I don't think it's the flashed firmware that is the problem, however please let me know if that's a possibility.
While the phone (or whatever) is hanging, I can still hold down the power button and I will feel haptic feedback as if the power menu has opened, and when the phone responds the power menu will be open, so the phone does still receive input. It just doesn't seem to act upon it or wake the screen properly. Is this perhaps merely a known Nougat bug or is it a glitch with my flashed stock firmware?
I'm sorry I don't have much more information. I do have Greenify, but I don't think that can or is set to disrupt anything that would affect the phone waking, or that would hang the OS, homescreen or whatever it is.
I haven't done other troubleshooting because I don't know what direction to attack this from, and that is why I have come here.
Help please!
Thanks in advance. :good:
UPDATE: It seems to happen directly after my screen shuts off from being on. So, if a notification wakes my phone but I don't interact with it in time and the screen goes off, when I press the power button it won't respond for ~10-15s. That's all I've really noticed... Anyone else have this problem??
BUMP.
Also, the same thing happens if I press the power button on my phone (by accident) and then go to turn it back on almost immediately - it won't respond for a while.
Cleared cache from recovery?
Got any settings enabled like "Keep screen off" which stops the screen coming on in your pocket, try disabling it in case that's causing it
Different gestures, disable them all in case they're messing with it
Last resort, factory reset

Won't be factory resetting unless I plan to root or something. I'll fiddle with the keep screen off setting that I do have on, and I highly doubt gestures would affect it but regardless I haven't enabled or used any. Thanks for the reply.
So the "Keep screen off" setting didn't affect anything. I turned Always On Display back on and I see the same issues. However, now sometimes I notice when I lock my screen or it shuts off, sometimes the AOD will appear and then quickly disappear, and stay in this hanging state for 10-15s. Then, if I haven't touched it during that time, the AOD will reappear. Any ideas? :/
So nobody else has this issue? This is still a problem, even if I press the power button and sometimes I'll want to turn it back on again as I just remember something to do before putting the phone away, it hangs on black for too long to be useful in that moment. The only potential solution is a factory reset?
Even if I lock the screen... If I try to turn it back on too soon, and I think it's specific timing... I have to wait 10-20 seconds. Sounds and vibrations still work.
UPDATE: This is still an issue. I've noticed a few more things, it does really seem like timing and as if there's some function in my phone literally not allowing me to turn on my screen - and I have never timed it but I think pressing buttons (power button) makes it take longer before it will respond again.

This happens for me also as a point of interest.
I am hoping that O solves it, since the monthly updates have never helped.
I haven't had this happen since upgrading to Oreo a week ago, so far so good!
24 hours dicking around with Flashtool, et al. Countless fails, reinstalls, re-downloads ... Horray, the fingerprint scanner now works.
So what? You still have to press the power button to get the screen to come on then position your finger correctly on the power button (thus, an extra step just to wake the phone up).
Is there some profound bit of knowledge​ I'm missing out on or is that all this fingerprint scanner can do? I mean, the amount of inet press on what an "epic fail" the entire US line of Xperias are due to the inability to use this pretty useless feature causes me to wonder if anybody who's reviewed the device has actually even touched one.
Anybody know how to use this thing as an alternate to logins or anything other than as a screen wake up?

Seems no more than normal.
It just seems there's a lot of bad press on a really great phone over a very minor, inconsequential feature. (Which once the Samsung 9 or Apple 8 come out, Sony's patent problems with the device will be over and they just slip it into an update. I'm sensing December ...)
If you haven't gone thru the trouble of this very frustrating issue of enabling the fingerprint scanner, do yourself a favor and don't bother with it. You can fully live your life AMD enjoy this beautifully engineered phone without it.
Hi everyone, I'm throwing this out there because I've run out of ideas about what has just happened to my U12+ (64gb) today.
I woke up and used my phone as normal, caught up on Twitter and the news, the usual apps etc. nothing untoward. The same routine I've had with my phone for the past 18 months of owning it with zero issues. My handset is stock OS (Android 9) and so not rooted or anything like that. Virtually all the apps I use are standard issue from the Play Store, nothing really "out there" and I have BitDefender installed to look after security. Same setup I've had for over a year. The battery was around 35% so I plugged it into my wall charger while I went off to grab some breakfast. When I returned a couple of hours later the light on the handset was green, I unplugged the charger and attempted to unlock it with my fingerprint.
The phone asked for my PIN, no big deal so I entered it. Black screen. Tapped the power button again, it requested my PIN again, I entered and... black screen. Okay, I was a little bit concerned now. I held down the power button so the haptic buzz occurred, held for 10/20/30 seconds, a minute... nothing, no restart. Tap the power button and it asks me for my PIN again and shows yet another black screen. I held down Power + Volume Down but again, nothing and no restart.
I asked someone to call me, the screen came to life and I could take the call but each time I tried to pull down the system tray in order to try and reach Settings to restart it asked me for my PIN, I entered it = black screen. The call was unaffected.
I removed my SIM + microSD card tray = same deal as above.
The phone is clearly responsive in some way and the screen does display to ask for my PIN but I can't get into it in order to reboot it. Extremely worrying.
Does anyone have any advice? At the moment I am faced with the prospect of simply allowing the battery to run out so the phone shuts down naturally but that is going to take the best part of 2 days.
I'm really disappointed because I was planning another 1-2 years use for this handset as I just bought a 1TB microSD card which has been fine in the phone for weeks so I don't think that's the cause. It is also genuine SanDisk.
Any suggestions or advice? Thanks in advance.
Hello, I hope you have made a backup with google backup recently... This does not happen often on android, but sometimes the system could have a problem. You can try this go the bootloader with the power and volume buttons , after recovery.. after apply a wipe data/ factory reset.. is will make a factory reset of your phone except the sd card. You should by fine after that and profit again.
Thanks, I appreciate your reply.
At the moment I am running the battery down until the handset switches off naturally. When it comes back on I will try to launch the phone normally, if that doesn't work I'll run the battery down again and attempt to reach the bootloader.
My photos are backed up to the cloud, I may lose some text messages but I managed to transfer the majority of my 2FA over to another Android device bar one.
At the end of the day if it's a choice between wiping it or a bricked/unusable handset then I don't really have one. What a pain.

At the moment I am running the battery down until the handset switches off naturally <----- why that??? Even on a bootloop or a black screen you can reset it hold the buttons power and the volume, you can go on the bootloader.

The first thing I tried to do was hold down the power button or the power button in tandem with the volume buttons but the handset won't restart. I tried loads of times holding it for different amounts of time and... nothing.
Trust me, I tried.
The only way I can get the device to switch off is by draining the battery. I'm almost at 20% so it shouldn't be too much longer.
Well I already got a black screen after flashing a module magisk.. I have holding the power button and the phone have restart no problem, same thing on bootloop. You need to be sure to hold the button correctly.

Yeah, I'm certain I was holding the buttons correctly. I tried about 20 times using different combinations just to be sure but the device would not restart. The haptic shock buttons are one of my least favourite features of the u12+, it's got to be said.
Anyway, the phone ran out of battery about 15 minutes ago. I left it alone for few minutes and switched it back on. It allowed me back in and the device appears to be fully functional again. I can unlock by thumb print, face or PIN without issue.
Basically, it's fixed. My only concern is I have no idea what caused it or if it will happen again.
Thanks for offering help though, I appreciate it. I'm not sure if this thread can be closed/locked now? I'll look into that.
Cheers.
Yes.. i love the buttons too i never got a problem with this. Great if is fixed! Maybe make a factory reset the next time.
I am wondering if the new flagship have haptic buttons too.. htc will announce it Tuesday.
