Does the phone encryption (stock unrooted 4.2.1) slow down the phone at all? Does it decrypt the storage at startup or on-the-fly?
Is there any point in encrypting the device if the bootloader is locked as unlocking to install a third party recovery to try read the data would wipe it anyway? (I already use a PIN for the lock screen)
Just trying to figure out if it's worth bothering...
I think the point of an encrypted hard drive is if an attacker has physical access to it. Meaning, they pull it out of the device and then attempt to read it. Locked bootloader won't help here, encryption will.
I believe it decrypts on startup.
My last phone, when encrypted, did not slow down at all. That was on 4.0.4 but I don't see why JB on faster hardware would be any different.

Great, thanks for the replies.

I just got my N4 and was curious about the encryption feature. I found this article to be informative and decided against encryption after reading it. Perhaps you may find it useful.

That was the kind of information I needed to decide against encrypting my whole phone.
I was poking security options within my phone, and I accidentally locked it with a pattern that I cannot recall.
I tried looking for troubleshooting guides, but unfortunately Marshmallow no longer has a "forgot code?" option. Also, I tried Android Device Manager, but it tells me since my phone already has a lockscreen, I no longer need to add a password (which I intended to do, in order to know said password)
I would greatly appreciate any help, since I really don't want to factory reset, since I got lots of pics I don't want to lose.

nope, this does not help. Just now i tried this on my device..if the device is locked adb doesn't recognize the device. this method does not work on marshmallow.
i don't know about lollipop. maybe it works.

Unfortunately, my phone is stock and non rooted, but luckily I could guess the pattern.
I still would like to know for future reference, since Android Device Manager did a great job at getting my phone's location and making it ring... just not unlocking it!!

you don't need to be rooted to access recovery and install files.
for future reference see the 2nd link i posted. I haven't tried that yet, i'l report when i try.

He wouldn't have been able to use it because you need a custom recovery to flash that file.
Well... I guess you know the system works? Probably not great for there to be an easy or sure-fire way to unlock a phone if you don't know the security details.
If it's just data you need, recovery mode should allow you to copy it off the device via USB (if you didnt encrypt the device). Getting into a phone you really locked yourself out of is probably not possible.

For preventative measures, Tasker is your friend. Have a "Plan B" microSD with a special .txt file on it, and have Tasker detect SD inserted and scan that file. If the file matches, then Tasker should wipe /data/system/gesture.key and password.key, and sqlite3 into settings.db and "update system set value=0 where name='lock_pattern_autolock' " to unlock your device.
In the case of an aftermath, it is now (as of today) possible to recover files/photos from the lockscreen without root, ADB, or custom recovery. Just an internet connection, linked Google account, and access to the notification drawer. I just published my first app, Locked-out Phone Backup, that is similar to the old Screen Lock Bypass Pro for Gingerbread, but instead recovers files instead of disabling the screen lock, so no root is required!
Hope this answers your question!
Well, try some password remover.
Hey guys , Since I upgraded to Nougat, my phone is pre-encrypted and why can't I decrypt it? Why is it like this? I want to decrypt it so that my phone will be a little faster. So how can I decrypt it?
Unlock, install twrp and format data.

Can't I just do it without unlocking? I can encrypt and unencrypt the phone easily(factory rest) on all my other devices?And any clues why is it pre-encrypted?
I suppose you could try a factory reset in stock recovery.

I've reset factory a couple times but that option is not choosable and it is written encrypted.
I mean I haven't even encrypted my phone ever , so why is it encrypted?Is it done automatically? What about yours?Is it pre-encrypted too?

Boot into TWRP and change the data partition type from f2s to EXT4.

Zte stock rom comes pre-encrypted on every new install. The only way to bypass it is to edl flash a stock rom with twrp. Boot right into twrp after the flash. Find a modded stock boot.img that has a modded fstab, flash it, then boot and your phone will be unencrypted with the stock rom.
Thank you all. I'll do as you said and unencrypt it.
DEAR ZTE CUSTOMER,
Pls describe clearly about the situation of your encrypted phone, because our developer confused about such encrypted issues. BTW, please provide your phone'IMEI.
Thank you!

No issues. It is encrypted by default in stock ROM.
This guy seems to be spamming and looking for imei info.
Mine is encrypted. Brand new out of box, updated to B10 MM then to B04 Nougat 7.1.1
What are the implications of it being encrypted? Mine is remaining stock, not even TWRP recovery or root. I'm happy if it's secure as I have personal and work SIM in it and will be using a couple of apps that look for root. Kind of tired of modding phones, just want life to be simple and reliable, able to take updates when I like. The work Nexus 5X was a ****ty phone but I got used to it being updated. It's a rare one that doesn't bootloop and is on Oreo but I hate carrying two phones thus the reason for buying the Axon 7 for dual SIM.

I don't believe you'll get more performance out of an unencrypted phone, or not enough to justify it for that matter. also, on some phones you need it not to be encrypted if you want to see the internal storage in TWRP, but on this phone it doesn't happen.
You can fix it in your settings--hand design(sort of, I guess),or you can update the latest version from ZTE office website. Good luck!
hellozes,
if turned ON, can "secure startup" be switched back to its original state or back to OFF?
no root no firmware upgrade..... just a test.
thanks.

Take 2 seconds to try it and find out
wrong answer.
hi ya.
you can turn it on and off at will, it will just ask for a pin number to turn it on, then the same pin you chose at startup, once back in the phone, you can go back to secure startup and turn it off if you dont want to use it. takes a while to startup using secure startup but its extra protection.
cheers.

my fear is with any potential irreversibility of the secure startup once initiated. I'd like to be able to fall back to default. IIRC, the LG G5 was one such case. Once encrypted, decryption was a NO.
thanks for your feedback!

not to sound rude but, you clearly knew that answer before asking the question. So, why ask it then?

you’re not sounding rude.
nothing is clear and, even if it is (unlike this case) then I like to double check once in a while, the “abundance of caution” thing.

Your s8 is already encrypted, most phones on stock rom are.
If you format /Data/ in twrp, on the next boot there is a kernel flag that force the phone encryption.

So the "sec start" option does not encrypt anything or it encrypts encrypted data?

ok, things are clearer now.
if a phone has “sec startup” enabled and you decide to root it, simply disable the option first and proceeed.

Okay thanks for the reply
Dead end thread, there have been many many many many many posts about that since oneplus introduced that a couple of years ago
THERE IS NO WAY TO GET RID OF THAT WHILE UNLOCKED
period
and there's a thread about it here. been following this from the start and apparently it's next to impossible to achieve.

I have experience doing that. Yes your device will definitely get BRICKED!!! Just ignore that boot screen, do not attempt to do anything to get rid of it. It just takes time to accept it. I use to think about getting rid of it as well when i was using my Oneplus 3. I re-locked the bootloader and got bricked. I couldn't do anything and had to send it back to Oneplus to fix it.
There have been other devices where they are able to replace the image with another, such as a blank image to hide the warning. I've also seen people load custom ROMs signed with their own signature so they can relock their bootloader after loading a custom OS. So there are things that can be done, but it's not something to just play around with, as mentioned, mess it up, and you'll brick something.
Thanks for the replies. Well I guess its just how it is, nit a big issue, was just wondering because most videos of custom roms I saw this part was cut out lol.
