Fingerprint after reboot for aosp? - Samsung Galaxy S7 Edge Questions and Answers

Hey guys,
I just installed an aosp rom and I use my launcher to lock the screen as a device admin. On my touchwiz based rom there's a mod that allows fingerprint to be used even after a reboot so whenever I lock the device using the device admin I can still unlock using the fingerprint.
However I couldn't find something similar for aosp, it constantly requires me to put in the pin and that's a little irritating. Is there a mod that I'm supposed to install because I couldn't find it.
Thanks guys
Edit: got root

fingerprint error

hi,
i installed the latest modem for my s5 last night and when i restarted my phone i couldn't use my fingerprint anymore
so i went to settings/ fingerprint i saw this message (check pic) i am using shorat rom, so i did a clean install of the rom again and no luck it didn't work. i tried to install another custom rom and this time it worked so it is a software related problem.
but i really love that shorat rom so i went back is there a fix for my problem of could i find the fingerprint APK somewhere so i coud install it again?
or any other help would be great
I recall seeing threads which mentioned that rooting + custom ROM's break certain TouchWiz features.
I hope this is not! I recommend that you browse the appropriate Custom ROM thread and search for the specific problem.

Imperium rom, lock screen problem, update just the bootloader?

I'm new to the whole custom rom scene so far have tried cyanogen mod and wasn't happy with the battery life, so have tried imperium rom, and I'm happy with it other than the fact I can't set a pin on it, I can only lock it using a pattern.
If I try and set a pin it either doesn't recognise it's been set and just unlocks the phone as normal or it unmounts the sd card. I'm sure I read about updating the boot loader solving it, and this may sound like a silly question, but is that not part of the custom rom anyway? If not how do I go about updating just that?

How to fix: I9505 touch doesnt response in recovery (TWRP) and also after boot

Hi,
I just changed from Stock ROM to latest lineage OS with TWRP. After installing some APPs, i figured out, when call comes in or out, display gets off (dark) and doesnt comes back easily. Now, touch doesnt response so I cant unlock with pattern. Booting to recovery doesnt give me touch response so I cant swipe for "allow changes".
How could i fix this? Maybe with flashing now Recovery or Kernel via Download Mode, but how to do? Thank u
I suggest flashing back to a completely stock ROM and start over.
The screen going black could be an indication of a problem with the proximity sensor. The touch could be a driver issue in the custom ROM.
Edit: Airdroid Mirror doesnt work to unlock pattern lock

Thank u,
but i forgot to tell u there is working USB Debugging with working Airdroid. Befor the issue Airdroid Mirror works great (control movements and clicks via Windows AirDroid Tool), but now with the issue i cant unlock pattern lock with airdroid. No response while moving Finger/Mouse but function keys like home work in Airdroid and also at touch.
Any idea how to fix this special thing? Is this an proximity sensor error?

Don't think the proximity sensor would be related to Android mirror.
Since you can't unlock the phone because the touch does not work, I would flash back to a stock ROM and check as many functions as possible. If the phone doesn't function properly on a stock ROM, it is unlikely to function properly on a custom ROM.

I just flashed one of some stock roms,this one: I9505XXUGNG2_I9505OXAGNG2_DBT frome the thread "go back to stock rom" and did wipe data factory reset. It installed some apps, but then no touch is responding.
I did opened phone, reconnected all cables but no luck. How to bring back touch is working?
Try one of the stock roms from samsung-firmware.org that is specifically for the carrier that originally issued the phone.
Could the problem be a loose connection?
Same problem here. Its an Samsung S4, german version.
I tried the jfvelte-version from https://twrp.me/samsung/samsunggalaxys4valueedition.html and it works great. Touch-screen works like a charm. Maybe this info will help other users.

Password and decryption issue

For starters, ive been using the same lockscreen pin on ALL of my devices for the past3 years, I know im using the right one. I recently installed the Evolution ROM and set it up with fingerprint and PIN. Fingerprint was working just fine, I rebooted the phone after installing a magisk module and now its telling me the pin for the lockscreen and TWRP is wrong. Again, I only use ONE pin and its telling me its wrong. Tried deleting the locksettings.db file to take off the screen lock and that worked but now phone just stays on "Phone is starting" and TWRP is still excrypted but lets me see all of my files, correct storage amount, and install zips.
When you installed did you format data?
I know this says Lineage, but it works for most custom ROMs, post #2 has the cliff notes version: [Guide]Installing Lineage
As for the locksettings.db, this isn't like older Android devices. You can't just do that, it doesn't fix the problem here.

STOCK ROM FREEZES AND BUG [EXTREME]

Hello, when using (D855) stock rom and stock based rom (Fulmics 8), the phone freezes extremely after the account and apps are installed, I can't take any action, The system is not responding, the home screen is not responding errors, also the phone is unavailable when I put a screen lock it becomes, the password cannot be entered (I don't think it's hardware related as it works very well when using Lineage OS) Used when Nova Launcher is installed (no screen lock), but when you open the notification panel, vibrate the phone, the phone becomes unusable when the settings are in overview. This only happens when using stock and stock-based rom (Fulmics 8). Is there a solution?
Help pls
