I heard Encryption is on by default, is that true?
Yes and it cannot be disabled.

Ok, so I've searched and searched all over the net for a fix but none seem to work. We are using Airwatch (MDM) at work. I wanted to remove it, so I removed the work Email and I removed Airwatch (removed it under device admin) then uninstalled it. But still every option under screen lock is greyed out and listed as disabled by my Admin except Password (High Security). I've also done Clear Credentials and made sure I de-encrypted the device and MicroSD card.
Any other suggestions short of wiping the device?
***update*** it looks like the MicroSD card never got de-crypted and was causing the issue. The odd thing is I even removed the MicroSD card for testing and everything was still locked out.
I want to use Android Device Encryption (Settings --> General --> Security). My questions are:
1). Is there any issue if my device is rooted and KNOX is disabled (it's still 0x0)
2). If anything to my device and I need to Odin, I assume encryption will NOT prevent me doing so?
3). Bonus question: is there anyway to use PIN when the device is encrypted? I only see "Password" and the rest is greyed out. I don't want to use 6 characters alphanumeric password everytime I want to use my device.
1) Yes, if you're rooted with a 100% stock ROM and recovery, you CAN encrypt.
2) Sort of. It might mess up the encryption. Mine got confused thinking it was still encrypted, but couldn't mount the partition after Odin ran. To fix it, boot to STOCK recovery using the hardware keys (vol+/home/power), and do a factory reset from in there. Note that CWM/TWRP etc will NOT work to fix this issue. It's something to do with the changes Samsung made to the encryption code.
3) Nope. Password only. In theory, it might be possible to do an Xposed module, but I didn't find a good place to hook in to the process. If they would separate the encryption password from the device lock code, this would be easy. I ended up using the No Lock Home Xposed module, which lets you switch to swipe screen lock when you are connected to particular wifi/cell/BT devices.
I'm actually running without encryption now. It makes custom ROMs difficult. I believe if I were running an AOSP derived ROM it would be fine, but using modded stock stuff causes issues. Make sure you do backups to SD or a computer. If something goes wrong with the encryption there is no way to recover without a full wipe, which kills everything on the internal storage, including /sdcard. The external SD card is not affected, unless you encrypted that as well. I like the extra security, but the implementation sucks and is buggy.
Hi. I plan on buying the 2017 A5, and I want a fully encrypted device. So there’s a question.
Will the CPU (with only A53 Cortexes) be enough for an acceptable experience with full device encryption? And if it is, will my device be encrypted out of box? AFAIK all the devices shipped with Marshmallow are required to be encrypted, unless the performance isn’t enough for on-the-fly seamless encryption. Is that the case here?
Data partition is encrypted by Stock out of the box.

So are you saying the phone is already encrypted? I have got my hands on A5 2017 and could not find device encryption option. The only option in device security is to encrypt SD Card

My guess that the phones that come encrypted out of box don't have that option because there's no use for it. That make them lack confirmation though.

U are right, stock is encrypted by default. No option to disable it only with a custom recovery and a boot patch
I am extremely paranoid (just my personality) and am wondering can I do a full device encryption like you can on pc? If so to what extent and how hard would it be to break? I looked into the built in encryption but its bypassable on to many devices. Also is it possible to have it that a password needs to be entered on the device when it's plugged into computer to allow MTP transfer (another password besides lock screen)

You could encrypt the sd card if you had one.

I know that but that isn't much and not really what I'm going for, yes SD encryption is something I want along with full encryption so at boot time a password is needed like you can do on windows

There's a setting called secure startup which requires a password at boot. I suppose that would do the same?

I have Secure Startup encryption enabled on my S9 and all I need to know if that only encrypts the files on the phone only when the whole phone is totally powered OFF or will it encrypt all the system files and personal files even if the phone is powered ON but LOCKED by the Screen Lock?
If that is not the case, will I need to use a third-party app to encrypt my files or even Samsung's Secure Folder app?
Thanks in advance!
