Has anyone else's device decided that it would be a great idea to encrypt itself after an update?.
Seems a bit random of htc or Google to do that..

Have you done a factory reset from Recovery to try and cure that?
Nope..

do you mean that it requires your PIN upon boot up? If that is what you're referring to, it is actually there whenever you power down or restart the device, not applied when it was updated.
Devices that ship with 6.0 Marshmallow are encrypted by default. If you are seeing a password screen before boot, that is device protection to stop a thief from being able to use the phone.
It specifically said "your device has been encrypted". I think it asked for the pin to continue, of which it then restarted straight into "optimising apps" and it was as it booted up after updating.
The pin request on boot is totally different. The screen I encountered was a white background with green writing. It was not part of the lock screen.

Yes, it does, and it's a bit confusing because it's not related to encryption at all (which is forced anyway). Remove "Require PIN (pattern/password) to start device" in Settings -> Security -> Screen Lock -> chosen screen lock method. It will turn off that weird menu after reboot.
I've had this same issue with my old htc u11 (running 8.1 Oreo). after i decided to do a factory reset it came up with this message "Phone is decrypted, enter your pin" before it finishes booting.
Luckily I knew the pin as it was the one I had previously used which had been stored in the OS. You can either go into settings and completely disable the screen lock, or set up a fingerprint. Doing either of these will remove the annoying decrypted message on boot up.

I've just encrypted my Nexus 5 under Android 5.0 and I was hoping I could set a decryption PIN just for the startup boot process, and not every time I unlock my phone. I haven't managed to find a way to do this, though: it's possible to enable a startup PIN if you enable the lock screen PIN, but I don't see a way to simply enable a startup PIN.
My goal is simple: to secure my phone when it's powered off, while making it comfortable to use when it's powered on. Can this be done?
Thank you!
Not by standard. Not sure what affects using apps that turn the secure lock on and off will have. You can test them.

i'd say you want your phone to boot if you loose it (so you can track it), don't you think?

That's reasonable in most cases. But there are situations and circumstances in which the data privacy has a higher priority than the ability to track the phone. Anyway the question can be considered independently from its motivations: can I separate the encryption key from the lock screen key? According to issue 29468 and this discussion, it seems it's still not possible.

according to this:
http://source.android.com/devices/tech/encryption/
out of the box, no because the lock screen password/PIN/ is used to encrypt the actual encryption key (randomly generated)
thank you very much b/c indirectly you answered the question I had (the reason I was browsing this thread), namely the boot password thinggy (as I said I'd like the phone to boot, baring an exploit, it's well protected: bootloader relocked, long password, impossible to flash anything without wiping - I sign my builds cm-12 with my own keys, and I crippled the recovery to allow only signed zips-, and no adb -even in recovery- connection outside my own computer, I installed cerberus in the system partition without a backup script, the only way to get rid of it is to explicitly format the system partition, and above all I don't trust the phone ).
that said, it should be possible may be to fiddle with vold's sources to make it so (separate passwords, it shouldn't be too hard ) the only problem in the absence of an "official" solution (be it in AOSP or the flavor du jour Android) the user is backed into a corner : build his own ROM from sources.
Hi Guys,
I just want to preface this by saying I cannot root my phone. Not because I am incapable but because this is my corporate phone and I would no longer be able to use it for work related things if I rooted it.
I am using a Bell Canada Samsung Galaxy S6. Every person I've come across that has an S6 or newer samsung phone is able to boot up on silent and not get the samsung noise when the logo comes up. I tried doing a hard reset on my phone just to test to see if my phone would boot silently if I set it on "Mute" mode and it did WITHOUT encryption but I am forced to use encryption by my company's device management policy app or I can't access other things like my e-mail.
Having said all this, does anyone know how to get the device to boot silently without rooting with these factors in mind? I reached out to samsung and they were clueless. As far as the support knows, the phones cannot boot without the noise even on "Mute" mode which is clearly not the case.
I'd really appreciate any help and insight. I've tried the Silent boot app as well with no success. I've noticed this happens only when encrypted and upon checking the volume settings on the screen where you have to put your encryption password after booting up, the volume settings are kicked back to default. This has to be the dumbest and most annoying oversight ever.

Just want to say, I am really annoyed by this too! Thankfully, I don't need to encrypt, and I just might decrypt because of this stupid issue.
Has anyone encrypted their device and if so, how is the performance afterwards? I'm asking because I know the performance on older phones nearly halved after encrypting.

It should come encrypted by default out of the box. In fact, I haven't seen any option to DECRYPT it. So, any benchmarks you see are for an encrypted device.

Hmmm seems it is. I searched the settings for encrypt and there is a setting for "Protect encrypted data" the description says "Device is encrypted. Protect your encrypted data by selecting Require screen lock when device turns on. This helps protect data on lost or stolen devices." There are two options "Require screen lock to decrypt data when devices turns on" and "Do not require".
I already have a lock screen set so I'm guessing the encryption doesn't work all the time without selecting the first option? Or would this force a lock screen no matter what, regardless of smart lock settings and/how long after screen turns off that the device locks?

My Best Guess on this option is that it controls when data is able to be read. "Do not require" allows the phone to read the data before the screen is unlocked, while the other option requires the screen to be unlocked first.
Why would it need to read the data before unlocking? Well, it my guess is correct, then the device would be mostly useless until that first unlock - unable to get new email, unable to know what wifi AP's it can connect to, etc.
Sadly, my interpretation might be way off on what this option does. It's not documented very well... I'm also not certain how the option relates in regards to "turning on" the device. Does that mean turning it on after a full reset, or after each time the device goes into standby (screen off)?
I can tell you that it does NOT decrypt the device and write decrypted data. It's function relates to the reading only. (In order to "read" encrypted data, it must be decrypted in memory.)
(Obviously, I haven't had a chance to play with the option to explore what it does and how it works...)

I think of "Protect encrypted data" as the pre-boot BitLocker password on Windows. When enabled, immediately after the bootloader completes, you're prompted for your unlock pattern. Only after the pattern is given will Android OS boot. It's kinda like a "keep the authorities off my phone" setting. Once powered off, even access to the filesystem from things like ADB is impossible until the pattern is supplied.

Lets hope its better than in 5.0 lollipop:
http://www.anandtech.com/show/8725/encryption-and-storage-performance-in-android-50-lollipop
IIRC it uses two pieces of data for the encryption, one is your password and the other is in hardware identifier on the device. Any Lollipop or higher device will typically be encrypted (with some exceptions because some devices lack the hardware for fast encrypting/decrypting) out of the box with just the hardware identifier and once you set the passcode lock will require that to decrypt the user data partition (IIRC this is the only partition encrypted). The settings toggle you mention adds a prompt on reboots to require the passcode on boot but afaik samsung doesn't change the actual android scheme of luks-like encryption. That said I may be full of it and Samsung Knox may invalidate everything I've said
I just played around with the settings...
It only impacts a boot or reboot (which is powering the device off and back on again, or selecting "restart" from the shutdown menu) (which is NOT standby/resume or screen off/on)
Assuming you have a fingerprint and password set up (if you have a fingerprint and pin, replace "password" with "pin):
If configured as "Do not require", it works as you expect.
If configured as "Require screen lock to decrypt data when devices turns on", it appears that the data partition is NOT decrypted on bootup. Nothing on the phone works until the password is entered. It doesn't allow fingerprints, has no notification shade, and doesn't even show the lockscreen wallpaper. (No email or other notifications seem to come through. I didn't test with phone calls.) Once the password is entered initially, the phone spends a couple minutes claiming that it's decrypting, and eventually it goes to the normal lock screen.
---
Be aware that smartphones (especially phones with Samsung Incompetent Engineering software) have been known to reboot at seemingly random times. It could be very frustrating to not get that important notification or phone call... and then realize it was all because the phone rebooted and is locked down until you enter a password. If you are aware of that risk, then by all means go ahead and lock it down. It certainly seems more secure.
When an app asks for permissions, Allow and Deny options show up (regardless if for storage, or camera, etc.) but the allow button does not work. Deny works fine. So far i have unlocked the bootloader via Huawei website method (i guess you call that official) and flashed twrp. I have not rooted the phone yet (getting to that, but one problem at a time) and this is the first one.
I also saw someone else ask, but with now answer. Is there a way to get rid of the splash scren about the phone being unlocked and not trustable, press power button again to boot?
Do you have an special theme activated? Use the standard theme and try again
My 1st question to you is... when the window prompts, do you flag the option "don't ask to me again" or not? Because if yes, the only option avalaible becomes the "deny" one. This mechanism confused me too some time ago, when i wasn't understanding why it was blacked out; Android takes your flag as an "what a bore, just shut up and go **** ya' self leavin' me alone" answer, so it automatically deactivate the possibility to let it pass even one more time. If you didn't checked the flag, i have another question for you. Did you maybe recently made an update OTA, or with an update package found online? If the 2nd answer is what u've done, do a check for being sure that you have updated the phone with the correct package model. (BLN-21, BLN-22, ecc.) If neither this is your case, begin to tell us something more 'bout your phone configuration and start to think to backup your data and do a factory reset for eliminate this weird issue.
For the question of yours about the Nag screen (the splash one, for being clear) at the moment there is nothing that we can do to avoid it to pop out; just skip it pressing immediately the power button, is the best advice that i can do so far
I'll attempt to answer all these at once since I just got home from work. I wouldn't believe rooting the phone would cause this issue, but the problem happened before i unlocked the bootloader so I think that rules that out. I do not use a special theme, but I do use squarehome launcher for my phone, not the standard android launcher. Problem there is, the problem occurs with either launcher being active. And theme wise, I have a 3-d live aquarium for a background (which if turned off and just a static wallpaper, the same behavior occurs). As far as the phone update goes, it was an OTA update from 6 to 7, so still using stock, nothing sideloaded or flashed (yet). My data is all backed up via My backup pro, and doing a full backup with TWRP onto OTG is not a problem. I prefer not throwing in the towel, since setting up squarehome perfectly is a pain in the ass, but if it has to happen, it is better than manually setting permissions for every app that needs them. Not sure what a screenshot would do, think of any app asking for permission to use phone storage, both the allow button and the deny button visible (in white, nothing grey) and allow doesn't respond where deny responds fine. and then i have to go in manually and grant the permission after the fact. I suppose I could just root my phone and give that a whirl, seems some bloatware needs to be removed anyway, and i have the SU sitting on my hard drive already. Thanx for the responses, and let me know what you may have come up with before I just factory reset it which as mentioned, I am dreading doing.

Well, I didn't think that would be the answer, but you, sir were right. I rooted my phone and it seemed to have fixed the problem. I don't believe I made any other change whatsoever. Thank you very much. Glad I tried it anyway as you suggested even though I didn't think it would be the answer. I am not above saying thank you, and I was wrong. Kudos. Maybe this will help someone else. Good thing is, I planned on rooting it anyway, and you just kicked me in the pants to do it.
Rooted but allow button is still not activated
Hello guys,
I wanted to activate app twin so I rooted my phone BLN-L21 android 7.0
Allow button still deactivated.
Also the boot screen that asks to press power button still exist.
I noticed that if I activate whatsapp twin it won't work simultaneously .
I.e : when you open whatsapp you get all missed calles & messeges.
Also I was able to download themes through themes app ,but now it just views the local themes.
Note: superSu is installed.
Any help will be appreciated.
Thank you
Well, I think this is not related to OP (or at least partially), but when unlocking bootloader after setting up SD card as the default storage can break some things, like default themes.
Try to restore your firmware, and then unlock the bootloader.
If successful, you can now set up SD card as default storage.

Its happened to me before i just wiped the phone. I even sometimes cant click install when installing an apk unless i lock and unlock the screen.
Hi everyone,
Yesterday I got a new update from EMUI and I allowed it. But when the phone restarted I found a new lock screen, from the app "Smart". I hated it so I disable the app (I can't uninstall it).
Now when I turn on my screen the first thing that shows up is "enter pin" insted of my wallpaper lock screen, notifications and clock.
Please hepl me with this problem, usually I turn on my screen to check my notifications and the time.
MY phone has Android 7.0 and EMUI 5.0.1
Thanks.
Do you have fingerprint on? It forces the pin lockscreen. On and off randomly on mine since that update which I put off until 2 days ago.
But if you disabled it can't you re enable it? One way would be a factory reset failing other methods like adb or app menu.

Sorry I forgot to mention that, I did the factory reset and wiped the cache. I've tried disable the finger print now, turned off then on with the power button but nothing. I tried too with the app menu but about the abd... I dont know about it.
i never heard of this nor did I ever encounter the issue, I don't think an app called "Smart" is by Huawei, I may be mistaken.
Pin and can't see notifications
I have The Same problem and I couldn't fix it..
