Hi,first things first,sorry for my english
I have a question about secure start-up screen.My device is encrypted and i'm unlocking it/booting with a pattern.Question is,is there ANY possibility to totally disable keyboard (unlock by pin option,emergency call) and make ONLY "pattern entering area" visible? Its Miui Global 12.0.3 Device rooted of course

From the online articles and the encryption description i was left with the impression that i will need to enter the password only on boot.
Well appears that once encrypted the only active unlock options become, face unlock, pin and password.
All take too long for my daily use, and since you don't have to use the encryption password for unlocking (the phone is decrypted on boot) but other options like face unlock, why we can't unlock with the normal slider screen or at least pattern unlock?
Is there a way to go around it and enable the slider unlock on an encrypted phone?
p.s.
i know that decreases the security, but knowing that if i lose my phone, chances are the battery will die before someone digs into it, and they will need to decrypt it then.... is enough for my needs.
what version of the os is it? and yes you can change it. you have to go into settings >>security>> and should give you the option to change it. you just have to disable encryption. worst comes to worst...FACTORY RESET
the idea is to change it and still be encrypted...
it's 4.1.1
I guess encryption is not that popular among android users?
Hi,
Is there any way to enable Face unlock with the device encrypted?
While the stock rom is forcing you to have the same pin/password for encryption and lock screen (pretty stupid but anyway), with vdc (or even in the settings app for omnirom) you can use a different password for encryption.
Thank you.
Hi there..
I'm trying ti understand device encryption before i install a custom ROM on my poco. (Any links explaining how encryption works on android would be greatly appreciated)
My first question is whether the pocophone encryption is turned on by default.
Under the encryption settings, the "encrypt device using lock screen password" slider is set to off.
However, every time I reboot the phone, i am forced to enter the lock screen password as fingerprint and facial recognition do not work. I assumed that this is because encryption had been enabled on my phone by default. But then why is the slider set to off?

The option that you are talking about under encryption settings, is the same as "Android secure start up" on AOSP. If you enable this option, you need to enter your device password while you restart the phone. Or else your device won't even boot up (and you won't see the lockscreen) completely and you will be stuck. It's an extra layer of security on top of lockscreen password/pattern/pin. Now coming to your second question, it's a security feature on android where no other unlock methods will work except PIN/Password/Pattern after you restart the device everytime. And it has nothing to do with encryption or decryption. Even if you decrypt the ROM, you will still have to enter your password or pin or pattern on every reboot. Only then all other unlock methods will start working. Some ROMs have a feature where you can bypass this security and unlock the device straight away on every reboot without entering the default pin or password/pattern. But they also put a disclaimer that it's not safe.
Thanks for the info.. But one of the questions "Is the Pocophone F1" encrypted by default?" is not yet answered. I am very interested to know. And (while I am asking) if not, "How can I do encrypt it"?
Yes, it is encrypted by default.
In Android 9 Pie (and earlier versions) there is a setting ‘Secure startup’, which is applicable in case of full device encryption (which comes by default in all new Android phones AFAIK). When ‘Require password when device turns on’ is enabled, the password must be entered at phone start and the phone won’t boot if no password is entered. When the other option ‘Do not require’ is enabled the phone starts and I can even receive phone calls, I just cannot unlock the phone.
So my question is: if ‘Require password when device turns on’ is NOT enabled – does this mean that my phone is NOT encrypted and if for example gets stolen, the thief will be able to download all my data to a PC (without unlocking the phone)? If this is true this seems like an absurdly easy way to bypass full device encryption...
Your data is encrypted by default. You can have it set to not encrypt it but it is not something I would advice of you.
As for the secure start up. As long as you have a locked bootloader and a password there are less then .01% of people that can hack into your device.

My phone is rooted and the bootloader is not locked AFAIK (it's Exynos).
I am not asking about bruteforce and other hacking techniques that could be used, I am just asking whether my phone is encrypted after boot and before the screen is unlocked.
Yes it is encrypted. Has been since the day you first day Bought it.
OK, but how come then my phone boots and is almost fully operational when ‘Require password when device turns on’ is NOT enabled (e.g. I can receive phone calls, calendar events pop up on screen - although I cannot see what they are all about because the screen is locked)?

Think of it as safe mode on PC. Not everything or all permissions are allowed when booting like that. It just a security feature and has nothing to do with encryption. It just locks out some info from being seen without the password.
Ill be honest with you. If you are worried about your data then dont be too worried. Unless you are someone important then your device is only useful for how much the hardware will get. Let me tell you how a phone theft goes.
1. Phone Stolen
2. Sim card removed
3. Device reset
4. If its locked then take it home and flash an OS to it or sell it to a pawn shop that is questionable.
Now the first 3 are normally done before you even know your device is gone (less then a minute)
Encryption bypass / Android (10) security issue after first unlock

I have discovered another security issue on a rooted device:
On my Magisk-rooted and encrypted Note 10+/Exynos (Android 10) I just found out, that the userdata (data/data ) partition is UNENCRYPTED and fully readable when viewed with an ADB viewer from my PC although the device is in lockscreen mode / locked!
This doesn't happen after reboot before the first unlock! After the device has been unlocked, accessed via ADB and re-locked (but not rebooted) it is (still) unencrypted, even after rebooting the PC!
Here the lockscreen password would not make much sense at every screenlock - it just unlocks the screen which can be bypassed and all data can be read via ADB anyway - it would only make sense once at boot. Is there a way to have two passwords (1 at boot and an easier one at screenlock) for example?
Is this a known bug? / Any ideas?
I have a few questions about being secure and things with the bootloader, and stuff like that.
#1: Is there anyway to be secure or thiefproof or even law enforcement proof with an unlocked bootloader?
#2: How does encryption work on Android. It Full disk encryption forced on by default, because I don't see the option anymore (except for SD card) How does it work? Does it encrypt the device till turned on? Till lock code in entered? Is it only there when there's a lock code? Does it work like Bitlocker?
#3: I wanna unlock my bootloader and install Lineage or Graphene OS. Since I can't relock the bootloader with custom rom or recovery (considering I have AT&T LG G8 THINQ and Xperia 5 II) can't anyone just flash TWRP or something, and even if the data's encrypted, just delete the security settings to bypass the lockscreen as shown in MANY tutorials and get to all my sensitive info and functions that way?
