Screen Lock security issue G975F Q Beta 2 - Samsung Galaxy S10+ Questions & Answers

Hi, Today I was using my phone and in mid day I realised my phone is not accepting my pin code but finger print is working fine.
I tried many time but pin didnt work and I used my pin code unlock few hours ago. Long story short I have reset my phone from recovery and setup my phone again.
BUT when I try to put a pin lock or password or any other security, my phone gives me error that is "Screen lock was already changed. Try again with the new screen lock." Screenshot attached
Any solution to this?
My phone is G975F on Android Q beta 2 DBT (VAU).
I have done factory reset , installed new firmware but it is not working.

Was this right after installing the beta 2? When you installed Beta 1 did you leave the system as it was or did you factory reset it? if so can you quantify how many times you unlocked your phone before went south? Was you stuck after rebooting from realizing your pin is not working? Meaning, after the issue and you restarted the phone was you able to enter your pin and proceed, then afterward it stopped?
[edit] The reason why I ask about the factory reset is in one of the other Beta threads people was having a lot of issues and after a factory reset it became near flawless. As of right now I''m monitoring my phone to see if this will happen to me, however after Beta 1 I did a factory reset, so I'm not sure it's a symptom of lingering files. I usally after applying an update to a beta ROM, I factory reset and out of all the times I did it, Android Q was the most buggy and was the only Beta i reverted, but the phone was a Pxiel..

I intalled beta 2. Everything was working fine. But when I restarted my phone, it stopped accepting my 4 digit pin. Then i hard reset the phone and factory reset. But after that it not accepting any new Pin or Pattern to register.

I did a clean install fresh firmware for beta 1, clear cache for beta 2.
I am not sure how many unlocks but i took few days after beta 2. My phone was waorking fine in morning as I unlock my phone in car using pin. But in after noon when I used the pin it showed me wrong pin. Every thing related to security wont work. Cant register finger print or face. But if you do same in secure folder everything will work fine.

Okay if it happens to me I will try to track down how it happened.

You did something and screwed up. A lot of people are using beta 2 already and have not encountered this issue, myself in it. I have done a lot of restarts and I have changed my pin successfully.

What about other people who are affected by it? Read comments in Android 10 beta thread on page after 135. You will find people reporting this issue.
I didnt do anything with my phone just updating with beta.

I'm another that's been affected, had to do a factory reset via bootloader.
Currently stuck on Beta 2, Smart switch won't downgrade.
No security options available and an extremely buggy phone.

A new update has been pushed out. I just received it on my phone. Will be performing a factory reset once the update is installed and will setup the phone from scratch.

Update me if it has fixed the security issue.

i installed *emergency update* , no wipe,no reset ,things go back to normal

Everything is cool as the phone has not been blocked. Otherwise there is no way to upload the update.
I wonder why they can't release the patch to upload it via ODIN, that would solve the problem.

Wait what !?!?, the same thing happened to me
Even worse - i rolled back to P, where i was able to add a pin but it would always forget it. I ended up going to a samsung center where they changed the board (in warranty), they said my unique device key was corrupted - likely due to internal storage error
So it is a beta problem then
Please provide feedback in the samsung members app. Those that cant, send feedback in the official thread at samsung forums.

Beta 2 is Terrible, having all kinds of Problems with it. Beta 1 was Much Better. Hope another Update comes out soon or will just go back to PIE. G975U S10+

I do have the same problem on my Zenfone 6z. After I relocked my bootloader I couldn't set up a pin. Asus still haven't rolled out an update.

reboots continue even with 4.4 STOCK

Hi guys, on 21th november arrived my Nexus 4 with EU warranty, bought on the site glistockisti.it. first time the phone had Android version 4.2 was giving me trouble, I'll explain, at the first configuration was restarted, then the phone notified me upgrade to 4.3, after many reboots the phone has been updated. The next day, however, the'll find a telephone notified me to upgrade to version Android 4.4 KitKat. Even then this update has been made, but now I have a somewhat unusual problem, the phone is unusable for me because of the constant reboots. I've tried using the factory image but although I have performed the procedure using the Toolkit, the reboots are still there. What can be according to you? I have to send the phone in for service or someone has encountered the same problems as me? If you have found them, how did you solve?
PS: the phone is now praticamenteo all original, not even the bootloader unlocked
Is it actually rebooting or does it just view the sim lock screen?

reboots continuously, the screen google, the bootanimation and reboot until it lights up, then use it for a while and then restarts again. I tried a hard reset and the factory image but the problem persists
Seems like a hardware issue if you already tried factory reset and are still having issues.
Sent from my shiny new(bought last Nov), scratch less Nexus 4!
often works normally and sometimes crashes and restarts, however I send assistance

SM910F Note 4 5.1.1 Random Freezes and Restarts

Hello there xda.
I have a Samsung Galaxy Note 4 SM910F.
So what is happening to my phone is that whenever I am in any random app lets say reddit or even chrome for example. It will like freeze for a minute or two and then unfreeze.
In more extreme cases it will reboot.
So this happened randomly because I flashed a Stock unbloated 5.1.1 ROM from here back in december and everything was working smoothly and stuff. I had xposed installed and all my apps. Then in February it started with this random freeze/reboot. I had not installed anything else apart from what I had for the last 3 months.
So I restarted the phone, changed the battery and stuff to see whether that will fix it. However it didn't. So I formatted the phone (the soft type) just so I can install another ROM. So I tried another ROM, flashed the correct CP and BL and stuff and then just installed chrome and whatsapp. After an hour or two the same thing happened. So this time I factory reset he phone, like a complete wipe and I installed the unbloated ROM once again with few apps. Same thing happened...
So my last resort was to install Cyonagen Mod. After an hour or two same thing happened...
I don't know what is the problem. I read about some peoples phones emmc failing and thus the freezing, but I am not sure yet.
Please could you guys explain what I should do to fix this?
Thank in advance!
I have the same problem. Starting on mid january. I'm on stock 5.1.1 with root and twrp recovery
Tried backup and factory reset
I went back to stock after I factory reset the phone. And still had the same problems.
People say that its a hardware problem... So I guess I'll have to send it back to Samsung soon.
I think I tripped the knox. I just have to unroot and get it back once again to stock and send it back. I hope that they accept it.
i have the same problem. my model is SM-N910W8 and I bought it from 2nd hand, so no receipt and no prove of purchase.
can I still send it back to samsung to fix it?
same problem as you and now my phone died completely .
my phone was 4 months and he has not supported any longer he died naturally lol.
my operator gave me another free under warranty because the phone had a faulty motherboard and after several back galaxy note 4
This started happening to me a week or so ago and my phone just got stuck in a boot loop after it froze and rebooted. I'm on the latest stock firmware. Tried factory reset, reflashed stock firmware, nothing helps. It still reboots (sometimes it almost gets booted completely, other times it reboots after 2 seconds.
Just disable finger print. Yes that magic feature offered by Samsung is causing more hungry that happiness since S5

Many thanks. This was driving me mad for a few days, I had tried three different ROMS, completely wiping everything. I eventually went back to stock, which I'm still running and it was the same; it would run fine for a few hours and then start to lock up until eventually it would either reboot or stop responding and I'd have to pull the battery to restart it.
Just not selecting fingerprint security doesn't work, you have to force stop "Fingerprints" in Application Manager (All).
just do not setup the finger print lol. I was having those problemes too when I bought the note 4 until someone tell "do not setup the finger print" lol, not I'm a happy user.... I hope that android 6.0.1 solve the probleme

Nougat - Decryption unsuccessful/failed - Lock screen related

Encrypted 6P with Nougat here. A week after flashing the OTA, unlocking the phone with the initial pin code worked fine, but I started having problems unlocking the phone again by swiping. It just wouldn't be swiped out of the way. It became more and more difficult . Had to reboot all the time in order to get access to the phone, through the pin code unlock.
Initially reflashing the OTA and removing 'trusted locations' for smart unlock seemed to do the trick. 10 hours later the phone went into the same problematic lock screen mode again. This time without any trusted locations.
Installed an alternative lock screen to see if that would work. This required disabling the default lock screen...
After the next boot up, the phone says that the password was correct, but 'decryption was unsuccessful" and the data is corrupt. Will need to perform a factory reset.
Does anyone know a way to avoid resetting the phone? Flashing back to the latest Marshmallow did not help.
Thanks so much.
OK, for anyone else finding themselves in this situation: make sure you get your backups off the phone before it's too late.
After a factory reset to Nougat everything is fine, but all my stuff is gone.

To start android, enter your PIN

i successfully downgraded my A2017G to Oreo b02 from b03 about a week ago. I had to do a factory reset, then set it up with my Google account and after that it allowed to install b02.
After that I've only installed a few basic apps for my bank and so on while waiting for b04 to show up through OTA.
Anyway, fast forward to today. I haven't had any issues with it. But all of a sudden when coming back from working in another town its rebooted and ask me to enter PIN to start Android. After that when it's done rebooting I got some weird double spacing between rows of icons.
So, I reboot again and once more i have to enter pin to start Android.. But it looks better when finished. However, this Enter PIN to start Android feels a bit annoying. Apparently it's because Android thinks my phone is behaving strange. Is there a way to find out what it thinks is strange and stop it?
It may be a security requirement for your banking app. It's secure boot.
This is part of the options with lock screen method. Maybe try setting the phone back to a swipe unlock and restart, see if it stops the problem. If so, set up you preferred lock arrangement again.
Thanks. Sounds reasonable although I've been running these apps on this phone since I bought it back in 2016(maybe it's time for a new phone) with various Android versions and never had this before. The phone has also been running for about a week with the same ROM and app version before this happened.
I'd backup data and reset it. See if it runs better, but you could try going to stock recovery and clear the cache first, just in case that helps.
There may be some junk from flashing it.
Seems like a factory reset did the trick. It's been running smoothly for some time nu despite installing the same apps again. I even got the b04 upgrade through OTA. Thanks!
Cool, so you're happy with the A7 again?
I regressed mine from B03 to B02 and did forced update to B04 from stock recovery. Had a few hiccups but sorted them and it works ok now. Do want to reset it when practical though. I use it for work so not in a huge hurry, setup is a big deal........

Sort of happy I guess. There are still a few things like it not automatically mounting my sdcard after reboot and I'm a little thoughtful about how many more updates it will receive. But it works rather well now and I haven't found a suitable replacement yet so I'm happy with it for the moment.

Can't Set Any Pattern, pin or password expect swipe on lock screen.

I had installed the one ui 2.0 beta. But after using few days when I restarted my phone and was unlocking it using the given pattern, it showed "Incorrect". So I downgraded it to android 9 one ui 1.1 using odin and sammobile. Now when I try to set any new screen lock it doesen't work. Its just stuck on swipe. Sometimes I even get "lockscreen settings force stops" message. Kindly someone please fix my problem.
Have you tried doing a data factory reset in recovery?
Install the new emergency update of android 10 beta. Otherwise there is no fix. Do do factory reset.
I get same issues. I do what OP do too with no luck, i do several time flashing android 9 pie with no luck. I hope somebody have an answer. I try to take my phone to service center tomorrow if the issue still ther
you can install last update 29/10/2019 by SD Card in theis post
