Android security - Redmi 6A Screen lock bypassed - Xiaomi Redmi 6A Questions & Answers

My friend had an unathorized access to her phone, a spouse bypassed her screen lock and I want to find out how was he able to do that so she can better secure herself. Her smartphone is Xiaomi Redmi 6A, software up to date.
So here's what happend. Her spouse sneaked inside her room during the night, took her phone (we know because sim and sd card were missing in the morning) and somehow bypassed the screen lock, accesed her facebook messenger, took some screen shots and then sent it to her (sort of blackmail purpose). I was also surprised to find out in the morning that "she" viewed my last message at 5 am with no reply, but turned out it was her spouse. He hasn't removed the lock, she had no idea he accessed it until reading his messages later on.
As far as I'm aware of, there is no possible solution to bypass the lock in a modern phone such as redmi 6A, without doing a hard reset and especially, without leaving the lock in place.
Any idea how was he able to access it in that scenario? Taking her sim and sd card might have something to do with it, but I have no idea. All I can think of is that he simply guessed the screen lock password, it was only 4 digits (android show the dots informing how many you should enter). And my guess is that it wasn't his first try.

Secondary screen lock - "SONY" - how do I remove?

Build Number 23.4.A.1.200
I've recently updated my Z2 to the above build number. Around the same time, I also added an Exchange account through my work that forces a 6-digit PIN and encryption of the phone's contents.
I find the 6-digit PIN unlock is annoying as it is because I'm used to the pattern unlock... but I've noticed that every time I type the PIN in wrong the first time, the secondary screen (pic attached) comes up and I have to type the word "SONY" (only works in upper case too!) before I can reattempt the PIN again.
I've tried to search around online but can't seem to find anything at all about that screen...
Does anyone know how to remove this secondary unlock screen so that I don't have to type "SONY"? It pretty much means I have to unlock my phone with two hands. I'm not sure if it's part of the firmware update or whether it's a security setting forced by my company policy via the Exchange settings.
I believe the purpose of the screen would be to prevent accidental entering of the PIN 5 times, for example, while it's in my pocket and subsequently causing the phone to wipe the contents.
Appreciate any help... thanks!

Stuck on PIN screen after flashing to Nougat

A few minutes ago, my Z5 compact finished updating Android. When I turned it on, it would accept the SIM-pin number no problem, but it will not take my phone PIN. The four dots show up when I enter it, but it will not unlock the phone. Since the PIN is required after a restart, that leaves me in a pickle because I can't open it with a fingerprint either.
Is this a common bug? Does anyone know how to fix it?
(Edit: The phone is working. I can see notifications coming in, and can delete them, but the phone still won't accept my PIN. Even after a restart.)

Desperate Error Android (!)

Hi all!
This is my first post, but not for a happy reason.
Briefly, I took my Asus Zenfone 4 screen (broken) to exchange.
The technician (friend that I trust) asked me my unlock pass (PIN) and unlock screen pass too, to restart it for tests. He removed the passwords to work freely. Restarted the phone 2 times, everything ok.
The problem (a bit desperate) is that now, supposedly for no reason, we can't access phone. Says: To start your Android, enter your PIN (Pin, not password, just numbers). Seems like smartphone took a PIN itself.
We tried old PIN few times but says that 3 more attempts and the data will be deleted (!!).
(Note: I had App Lock installed and protected almost all important apps with the same Pin, but I think there's nothing to do with this problem).
The only solution will be reset the system?? Unfortunately I have some files without backup that I can't lose.
There is any original Pin?
Any help is welcomed! Thank you so much!

Unlock pattern not working, cannot unlock S10

Hi,
My friend has been using Samsung S10 for a year, now few days ago she turned on pattern unlock.
But as soon as pattern showed up for the first time, it did not work - line, which should connect dots, is disappearing as she tries to write the pattern, so it never unlocks.
She went to local Samsung OEM repair shop, and they said it is under warranty, will repair, but she will of course loose all saved content. Of course she does not want to loose hundreds of photos of her just born child...
I've tried via Google account, but phone is offline. Somehow it stuck in Airplane mode, so it does not want to be managed by Google
Samsung account was not configured.
I should not root it due to warranty.
Tried ADB, but unknown sources are not enabled, so I cannot access.
Any other idea how to get her pictures downloaded with locked phone? She just needs camera photos, everything else can be wiped out.

Oppo phone unresponsive once booted. Need ideas how to troubleshoot

Good evening everybody,
my Oppo Reno 4 5G is behaving strangely / not at all since yesterday. Over night I forgot to recharge it and the battery drained flat. Next morning I recharged the phone (luckily waking up by my inner clock) and found the phone unresponsive after boot. On the Screen, only a closed lock icon is visible. When I tried to use the touchscreen, the screen flickered randomly. I attached a Video file where you can see it yourself. Other than that it will respond to no input. I even tried to attach a USB Mouse/Keyboard, but it was still unresponsive to any input. When I hold press the power button, only an empty grey box appeared. Removing the SIM card made no difference. Strangely my alarm clock was working fine when it rung.
I managed to get it into the recovery-mode. When I try to do an online or local update it asks for the lockscreen password. But I use fingerprint + pattern to unlock my phone, I don't remember setting any password. I tried already a dozen passwords i used in the past and translated the pattern into numbers but no chance. I also don't have a Google Account connected to my phone, if that's relevant. The only thing I can do in recovery is to format the phone, but I see it as a last resort. My last Backup is 3 weeks old so it wouldn't hurt that much but I actually want to keep the pictures because I was on holiday for the first time since covid in the meantime.
Has anyone ideas how to troubleshoot the problem further? It seems to boot fine, only the lockscreen seems to be broken.
Phone: Oppo Reno 4 5G (european version)
Modelnr: CPH2091
OS: Android 11 / stock ColorOS
I'm thankful to any ideas!
