Hi all.
The LCD of my A52s is broken. Android 12
I wanted to make an Backup but I cant access the files unless the display is unlocked.
I have registered a pattern and a Fingerprint.
Tried to use fingerprint : vibrating but not working
Tried Samsung Find my mobile to unlock screen : Not working, says "Remote unlocking is deactivated"
What are my options if there are any?
Dont want to root it.
Thank you in advance.
//edit :
Not sure if USB Debugging is enabled.
Otg usb adapter and a mouse

Mouses are relative positioning things. That makes life more difficult.
A digitizer pad would be better, but those too do a bit of panning.
You want an absolute pointer device.
I had an old hardware project that I just updated and used to debug some media commands.
It uses a serial port from a desktop that feeds a µC that is a peripheral to an Android over OTG.
So you can put absolute positioned clicks into an unrooted, non-ADB device.
But it seems to have a bug now. I have to look into it.
Dumb question: Do you need to swipe to enter your password or can you just click?

By password you mean the pattern to unlock? Its swiping.

Yeah, I've never used it so I didn't know if you could just tap the dots in succession along the path.
Not a big deal or difference, if I could just get the HID report descriptor working.
Edit: Ah, got it working. Android doesn't seem to like it when a USB peripheral is a keyboard, consumer control, mouse and digitizer.
So I took the mouse out.
Did I guess your swipe pattern?
Do the swipe dots appear in your login screen centered exactly vertically?

It looks like this =)
Thats not my display by the way.
When I try to use the fingerprint, it vibrates but the phone does not recognize it.
It's kind of pesky that the aspect ratio, the vertical position and the scale of the layout are all a bit variable.
At least the aspect ratio is a solid number. Height in pixels/Width in pixels. I make yours to be 2.18?
Too bad you didn't try to do this when your display was working!
My setup works fine, but that isn't really going to help you any at this stage.
I was thinking of getting a separate Android to use as the "digitizer" but that means getting a Linux USB HID gadget working.
That looks like a bunch of work and moreover it's not universal for any Android.
So, I don't know that this is going anywhere. It's even possible your device locks out USB OTG when you're not logged in.
That's easy enough to check, just use a OTG adapter and a USB device with a LED, flash drive, mouse, keyboard...
If you can borrow a Wacom tablet from someone that might operate in absolute coordinates.
The problem is, it can operate in relative mode too and without the Wacom software installed you won't be able to switch it.
The last Wacom I had just plugged into Windows and operated as relative.

Unless you have an ATMega32u4 and a UART I don't know what we can do.
The Raspberry Pi 0W could do this too, but I'd have to write all the code for it.

I really appreciate the time and thoughts you put into this problem.
But -> "no backup no sympathy"
I was my fault not doing a regular Backup and so I guess the data is gone. I might just let samsung change the display and hope they wont reset the device.
It's too bad you're not local. This would be a piece of cake.
It's actually so much fun watching this thing login.
I wrote a cleaned-up Windows program for this. Now the command is:
Code:
C:\>swiper /c3 /a2 /y0.683 /u 791364
The "password" uses the position of the digits on the keypad.
Unfortunately I've never done a deep dive into the whole encryption of /data
Is there a TWRP that can decrypt? Does that require swiping too?
I dunno, I might be able to mail you a RPi0 with code on it.
Still, if you didn't leave ADB on, it will be a big pain to enable it.
You could also buy a replacement screen and just connect it up floppy-wise without removing the old screen.
Sometimes the most simple ideas are the best.
We used cling film on the same model and painted dots on the film where the pattern is.
Put that cling film on my phone and swiped my pattern. After a few tries it unlocked.
Using my fingerprint wasn possible.
Oh! I thought that the touch screen itself was non-responsive.
I had presumed that you had unlocked it enough times that you could unlock it without looking.
In any case, I've had fun with this. My new secret unlock pattern is:
This has maximal pointyness and requires coordination to swipe between the dots without catching the wrong ones.
If they only gave us a choice of 4x4 or 5x5 we could come up with a pattern that a human couldn't do!

So my wife broke here 101. the lcd/digitizer is completely shattered. I was wondering if someone could do me a favor and record the exact sequence of key presses required to get from the home screen in Urukdroid to the settings>applications>development menu and enable usb debugging using a usb keyboard.
My idea is to enable usb debugging, then use androidscreencast to enable hdmi, and use the tablet as entertainment device that is permanently connected to my TV.
If anyone could help by recording the exact key sequence required or come up with another way to view the android interface on a device with a broken LCD I would be eternally thankful.
As a side note, I am sure that the USB debugging has been disabled, as my wife always disables it on all her android devices (she doesn't like the extra popup when she connects her devices to a computer).
Sorry to about that. Did you try to contact Archos? They may be able to help in some way??
out of curiosity, are you talking about a G8 or G9? Does this confirm the outer surface (part you touch) is glass or just glass under with plastic on top ...hope that's not to dumb question
Hi madmachinist,
Did you get anywhere with your Archos? I want to do exactly the same thing after mine got broken last year.
Cheers

Hey, I'm currently on the Oneplus One and have never had problems with it. A few weeks ago however, i dropped it with flipcase from 30 cm not really hard or something, no physical damage visible. But at first the touchscreen didn't respond at all and after rebooting, everything worked except for a 2 cm stripe of the lower touchscreen + capacitive buttons.
So i wanted to root it and find options to workaround this issue. But in order to do that, I needed to unlock it and delete all of the userdata + settings, so basically a factory reset. (see android-hilfe (Dot) de/thema/how-to-oneplus-one-rootanleitung-unlock-recovery-rootvorgang-von-a-z.596012/ )
Now I'm pretty much stuck in the cyanogenmod setup (set language etc.) where I can't the option 'Next' due to the broken touchscreen in the lower section (see drive.google (Dot) com/file/d/0BwIC1YNaC4EMTEdOaHYycU15T0U/view?usp=sharing )
It's really a stupid reason why I can't continue and because of that, I can't enable USB Debugging and, of course, adb. Fastboot is enabled, TWRP is installed. Any way to bypass the setup or enable USB debugging from the PC (that wouldn't really solve the CM setup issue though)
Thanks for the help!
Maybe an easier solution: Get a USB OTG cable and use a mouse and/or keyboard to get through the set up. Once you do, you can use something like LMT Launcher (my favorite) and set it up to activate from a side swipe and you'll be able to get around the phone decently.

Is it possible to control the phone without USB debugging activated?

Omg thank you, I was really frustrated but it worked!
Glad to be of service!
Greetings fellow techno-wizards! Got a big problem that I'm hoping you can help me with.
Long story short, my trusty Pixel 2 had one too many drops, now the screen won't turn on and won't respond to touch. The logic board is operating, and I haven't rebooted since then, so I can unlock with the fingerprint sensor.
I plan on getting an Pixel 5 when it releases, and have an LTE Tablet to limp along until then.
My biggest problem is authenticators on my phone that I may or maynot have the backup QR code for, as well as many other things I'd like to get off the phone before I retire it.
I have the following things at my disposal:
Pixel 2, with USB Debugging turned on, and recently trusted the PC. No screen, no touchscreen.
WearOS watch paired to phone (can get notifications and texts)
Bluetooth Mouse
Wired mouse with USB to USB C adapter
Chromecast
Win PC with Scrcpy installed, already tried to use it to show the screen on the PC, I'm guessing its been too long and I have to press a notification to trust the PC.
The Goal:
To cast the screen to a chromecast and pair a bluetooth mouse, and/or get Scrcpy working by accepting the dialog that I can't see. This would allow me to use the migrate tool to the new phone I will eventually get.
I tried long ago to use a USB C to HDMI adapter, that doesn't work. Google wants you to use a Chromecast for such things (Thanks a ton Google )
The thing I need to figure out next is how to use ADB to force the phone to start casting to a Chromecast, or to remotely accept the dialog. The wired mouse with adapter should work to control the phone instead of the touchscreen, but without any video out, I'm clicking blindly. The microphones are working, but I've never tried to command the assistant to start casting before.
Can anyone suggest the next step I should try?
Just had a thought, there are accessibility features for blind people that would let them use the screen without seeing it. Is there any ADB command to enable these features? If I plug in a keyboard, is there a keystroke combination to turn them on?

Since you say ADB is enabled on the phone you should be able to pull out by means of ADB-driver the data in mind to your Windows computer.
I've been stalking this forum for a few years now, from back before all the pop ups, but for the first time i'm stumped. Here's the rundown: i broke my pixel 6. not terribly heartbroken, the phone is ****, everything it does "well" is only moderate on any other phone i've owned.... sorry, digression. Anyway, screen is completely black and unresponsive to touch. screen is locked with 6 digit pin. I know the pin. but i cant enter it because the unresponsive screen. Phone gives haptic feedback when a wireless mouse is plugged into a multi port adapter, which i bought intending to plug the phone into an hdmi port... but back to the pixel 6 being a ****ty phone, i have to install an app to do so, since the phone doesn't do it natively.....which i cant do, because it seems that while usb debugging may be on (adb detects the phone) i cant authorize the computer.... even though ive done it a hundred times, always clicking "always allow from device" sorry, digression again. i just want to get my **** off of this phone. guys at cell phone store are either incapable or incompetent, because they say they need touchscreen access. i have otg adapter, multiport adapter, wireless keyboard/mouse....can anyone help me?
EDIT broken phone has to go back to the insurance company in....6 days
If your mouse works, can't you backup your info to your google account?

Maybe if the info is important, just transfer the board of your current pixel to a used one

sure would, hell, it does. except that im still signed in on the old phone. and since that is the case, google keeps asking me to verify my identity via broken phone. and trying to do account recovery results in an email explaining that im signed in on another device, and if i want to change my password, i can do so on that device
Oh ok

you see my dilemma?
You may be able to project your screen with a wired dock (see https://support.google.com/pixelphone/answer/2865484?hl=en). By following the directions and begging for or borrowing a USB-C dock from someone, you should be able to get your stuff off your device, especially as you can connect a mouse to the dock if touch doesn't work.
The other alternative that may work for you is to go into fastboot (long press power to shut off the device, then press and hold volume down while pressing and holding power) and use ADB to backup your device, including the storage. See https://www.technipages.com/how-to-backup-your-entire-android-device for details, and pay attention to the -shared flag.
I am wating to use an Android tablet for the main dash in my car running the MSDroid app. There are a few key requirements I need to meet to be able to keep my car road legal using this and I am hoping someone will know how to make this stuff happen from a software point of view.
- The device must power up and down when the key is turned off and on
- When powering up the device must load straight in to the MSDroid app and automatically connect via Bluetooth to the ECU
Any advice would be very greatly appreciated, thank you

Even bad advice?
I don't like too much in my face, so I put a little OLED display where the coolant temperature was.
It's run off a little microcontroller that connects directly to my (ancient, 1995) OBD-1 ECM.
It also spits out that data over USB to my Android navigation tablet so I can see a full screen OBD.
The little display can show OBD codes if they pop up.
The lower left line of the display shows engine running time (when it's running).
I find that important to make sure that I get a coffee every hour.
The images are of the old blue in emulation mode, the new yellow (engine off) and the OBD app.

Thanks,
I'm running an aftermarket ecu on a street/strip car and need to run a tablet for what I want.
As per original post, there are two key things I need to do which will need modded Android software.
