How to draw pattern lock from mouse on broken LCD - Samsung Galaxy S9+ Questions & Answers

Hello there !
A friend of my wife broke the screen of her S9+ and asked me if I can extract the photos.
The phone does work fine, but the screen and the digitizer are dead.
I'm trying to use the MHL capability (usb c to hdmi + USB to connect a keyboard or mouse) to get access to the phone, but I'm stuck to unlock the screen. I was told that's a pattern lock (I know the pattern) but I can't display it on the external screen, and I can only draw it using a mouse on a black screen... Almost impossible !
Is there a way to bypass the pattern lock to get the pin code, or something to draw the pattern, or a way to show the lock screen on an external screen ? I tested on my own OnePlus 9 Pro, it doesn't display the lock screen neither.
I didn't try recovery, and adb looks disabled...
Thanks for ideas

Thats strange because when I use my (official) DeX dock, I can see my lock screen on the second display and use a keyboard or mouse to unlock a pattern, pin or password. I'm also confused because you say its not displaying on the second screen so how do you know your on the lock screen? Unfortunately, adb won't work until you unlock the phone as you will need to enable developer options and also accept the "fingerprint" before adb connects. Recovery is useless to you if you intend on recovering photos and the whole point of a lock screen is not to be bypassed. Obviously, there are ways because law enforcement can do it but your unlikely to have the equipment or exploits or skills to go down that route.

Thanks for the feedback !
In fact, the Galaxy acts just like my own phone on th external screen : I have a black screen with the date/clock moving around and a padlock. When I test on my phone (that's a biometric finger), I just have to hit the spacebar, it turns my phone screen on (the external screen keeps the same black display), and from my external keyboard, I can type my password, I hit enter, and unlocked.
Here, I am trying the same (I have a password code) but no luck, I'm just stuck on the lock screen. Pretty difficult as I can't monitor what's happening on the Galaxy's screen while I'm trying this. It does react correctly when I hit a key (it does wake up the Galaxy).
As expected, the MHL is not supported in firmware mode (I have lots of troubles going to recovery, I think the volume button was a bit shot too) so I can't see on the screen what I do in it...
That's very frustating as I'm stuck for this pattern.
Is it possible to get a screenshot of the S9+ lock screen, or to see what happens at fresh boot when using a keyboard ? The idea is to make sure I can access the password code screen, or if I can navigate to it with the arrows or a key... If I can access the password screen, I think it will do it (If the password is correct of course...)
Thanks

Use samsung find my device to erase your lockscreen password/pattern. Dex will then automatically launch upon connecting usb c to HDMI adapter depending on your settings. I had done this once before. Worked flawlessly. I eventually replaced the screen though.

Thanks, I'll try this but I don't know if it's enabled. I noted this method, but I was a bit scared to delete the content, as the goal is just to recover her photos. I haven't done anything else on it so far, and I'd like not to change the screen as the part is very expensive and the replacement looks... Erm... crappy ?

Back ! No luck, still waiting to know if there's a Samsung account enabled. I tried again today, no luck. But it looks I'm not passing the "lock" screen (the one with the wallpaper and the date/time). The spacebar may not unlock the device ? I've been trying with a mouse, but I think I'm stuck on that screen and I can't even access the pattern screen.

Maybe trying to find an official Dex dock. Many Chinese version of "usb c to hdmi + USB" won't work well.

[SOLVED] Broken screen, factory restored thru Lapdock, what now?

Edit: Solved! See post #3 for information on how I solved this.
Long story short I got an AT&T Atrix from a friend with an Atrix Lapdock. I'm not 100% sure of the details but he had opened the Atrix (to replace the digitizer I think) and messed up the screen to where the backlight turns on but it's always black. The digitizer still works. He wanted me to factory restore the Atrix so I did so via the Lapdock by going into settings and selecting factory restore. After it booted up again it did not boot into Webtop mode. Well great, now I'm running the phone blind.
I think I was at the "Emergency calls only" screen since clicking the bottom of the screen above the soft buttons, then towards the top, played dialtones, so I got a SIM card (out of my Sprint Touch Pro 2, just for the sake of having any SIM card in it) and rebooted with the SIM in it. I'm at a different screen now, where I can make the motor buzz by tapping the soft buttons, and if I hold the Menu (4 squares icon, leftmost soft button) it pulls up a keyboard. I believe this is the Motoblur setup screen. As stupid as it may sound, I tried entering the "123/alt/abc/e/123/alt/abc/e/b/l/u/r/o/f/f" command by eyeballing the screen, but I don't think I deactivated it since it seemed like I could still interact with this screen the same way. I tried pressing (what I felt was) 123/alt/abc on the phone, and using the Lapdock to input the letters, but that didn't seem to do anything either.
ADB is definitely not enabled, I can launch fastboot (or any of the fastboot options, such as "Fastboot" "NVFlash" "BP HW Bypass..." etc, I wrote these down and just blindly input however many Down presses to activate it).
My next plan is to print off a screenshot of the Atrix keyboard to-scale with the screen and use that as a guide to input the "bluroff" command, hopefully doing that will get the phone into a state where it can activate Webtop.
Strangely, while I was in the presumed Emergency Calls mode without a SIM, either me spazzing out on the screen or some weird luck got the Entertainment Center to appear. However I could not navigate it at all using the Lapdock, not through arrow keys or using the mouse. I've never gotten that to happen again.
If this is a failure, my main purpose in getting these from him was to use the Lapdock as a small and luggable HDMI monitor (via adapters) so I'm not too disappointed, but it would be nice to have the Atrix working as much as it did prior to factory-restoring it.

wow....thats something.......you still int blur account setting (it uppen when you use a different sim card)....
try to wipe in fastboot
load new rom image that can skip motoblur account set up (like nottach)
when reboots click menu and then right corner down (skip set up) then it should be able to go in webtop mode..

Posting to say this worked fine! I used Photoshop to print a screenshot 1.961" wide, carefully cut it out, taped it to the front, called up the keyboard (longpress the menu button, you'll feel it buzz long then very short), and carefully tapped out the Motoblur override. Took a few tries since you can't see what you're tapping (go slowly and use the tip of your finger) and the paper in the way makes it less sensitive. The phone doesn't buzz or anything when it does this, but if you put it on the Lapdock you'll see the swirly small red Motorola M icon signifying Webtop is loading, instead of the big red Motorola M icon that jumps around now and then. Also I had set the language to Spanish during my blind mashing, luckily I'm familiar enough with it to where I could change the language to English easily.
You can activate Motoblur through Webtop after you bypass the initial setup, I'm doing that right now.
htchd2fix I was considering loading up a ROM and seeing if that gave me more luck, but I wasn't sure how they handle Blur and all that, but anyway thanks for your step by step
I've attached the screenshot I used of the stock Atrix keyboard, and a Photoshop PSD I made that I used for printing, scaled to (more or less) the Atrix's width, cleaned up a bit, and with a black 1px border to assist in cutting. To whoever made the original screenshot (you're probably on XDA), thank you!
I'm leaving the screenshot taped to the Atrix for now so I can brag about its e-paper display

[Q] Unlocking your phone in different ways

I was wondering if there was a way to do this. You wake up your phone, it's locked. You hold the sleep button and the phone goes straight to the home screen.
Or even better, you wake the phone up by holding the sleep button and the phone idles on the lock screen for a second and then jumps to the home screen (similar to iPhone's new fingerprint scanner, but without the scanner). Maybe the lock screen can have a fake pin lock to mislead people using my phone.
I've been waiting for this for years but I don't think anyone's developed it. Would there be a way I could do it with Tasker? Or maybe there's something on xda that I can download for it to work? I am rooted with a Note 3.
Also, if there are any other revolutionary new lockscreen's out there, let me know! I'm not into the whole typing a password to unlock because everyone sees the password anyway. Plus it's tedious. Any ideas?

CM 12.1 Lock screen woes

Help! In trying to get my swipe lock screen to self-actvate when the screen turns off, I've managed to make the problem worse.
I made it PIN lock, intending to return to Swipe after testing. Now there are NO options for locking except PIN and no obvious way to clear it. I've read all kinds of suggestions, none of which worked. Surely this is not a "feature"?
Edit: Oh, duh. I can't believe this isn't documented somewhere. So you just go to the settings menu under Lock Screen and it says PIN. You touch that and it asks you to confirm your PIN. When you do you are presented with all the options again (including Swipe). Whew! Now if only the #%@#$ thing would engage when the screen turns off like it should!

Full screen mode and pattern lock screen issues

Having two issues with my S9+ I just got today. Hoping someone can help:
1.) Full screen mode - I opened up a game which displayed in the correct resolution, but didn't take up the entire screen. There was a small area of black at both the top and bottom of the screen, so the game was not taking up the whole screen. I turned on full screen mode, which fixed this problem, however, it basically lowered the resolution on the game and it made everything huge. Can't seem to fix this to where my game uses the whole screen and the correct resolution like it should and does on other phones.
2.) Lock screen pattern - On previous android phones, the 9 dot pattern would automatically show up when I pressed the power button to turn the screen on. On this phone, it's not. Also, the 9 dot pattern box is small compared to what it used to be on other phones. I have it set currently to not show the swipe pattern when I swipe in my pattern to unlock the phone, but I'd like to not have to swipe first to get the pattern box to show, as well as make the pattern box bigger. On my old phone (LG V10) there's an option under lock screen settings that says "Hidden Pattern - Show pattern dots when tapping on the screen" that turns it on so the swipe box comes up as soon as you turn the screen on. Can't find this on the new version.
Any ideas?
Thanks

Broken screen and displaying anything.

Hi, i wanna ask a few questions about my old phone. It was working and i had dropped it. in that minute a car just went over it. It was touchable but display is very messed. I had saw the main screen and i could touch it. After that i just removed my sim and tried to restart phone but it never did restart. i could enter the twrp and take all my files to pc. after some time it's screen went black. Now i can enter to download mode, i can confirm that but nothing more because of black screen.
And my question;
1. How can i be sure if i change the screen it will work again?
2. I don't want to buy a screen, is there way to use it without a screen? ( with a monitor, tv etc.). i can use a mouse and keyboard with otg but how to transfer display to another device? ( new screen costs too much ) ( i know mhl not supported)
3. is there another phone which is cheaper and screen fits to s6 edge connector?
4. Any other ideas?
