How to force screen mirror an A50 to a laptop - Samsung Galaxy A50 Questions & Answers

Hello. I have an A50, and the screen has been losing touch responsiveness often. Is there a program that forces the screen to mirror to a laptop? The phone is unresponsive to touch so I can unlock the screen (though it has no pin or password at the moment), has debug mode enabled. Thanks in advance.

yes you can

I just tried and the noconsole.exe file did nothing, or so it seems after double-clicking.

make sure your device adb driver installed on your pc/laptop

Use the app "EVA Facial Mouse" which tracks face and moves the pointer on your phone.
First,to install this app you need a actual usb mouse to navigate since your touch is not working.
Once the accessibility service of "EVA Facial Mouse" is enabled you can do any on screen actions.

Change the option to File Transfer from the popup/notification on your phone when you connect it to the PC. It works for me.
EDIT: If it still doesn't change, check the adb drivers.

i am not getting any popup.
Check the sliding switch on the right hand edge of the op3 is "down" to allow ALL notifications. There are plenty of "install OP3 drivers" videos on Youtube. Windows drivers are also on the phone.
This should still work - the drivers are also supplied on the phone. Doing nothing other than connecting a op3 to a windows pc should cause a cd drive to appear in Windows Device Manager and in File Explorer (look under "This PC") for "CD Drive (drive letter: OnePlus Drivers" . Double Click the icon and run "OnePlus_USB_Drivers_Setup.exe". If you are running a recent version (and clean installed in the last few months) of W10 Pro then you may hit driver signing issues

Screen shattered, can i get back my files?

I have a rooted Oneplus 3 with TWRP installed. My screen shattered and it is unusable. It's totally black and I do not think the touch is working, but I think the phone itself is working. Any suggestions?
If you have USB debugging enabled, you can connect it to PC and use "adb pull" command to get files from the phone.
Or simply browse its storage in PC's file explorer if MTP is enabled by default.

I thnk mtp is enabled by default in twrp. You can try getting your files from there

If you have debugging enabled, you can easily grab all your files either using adb pull, or booting to TWRP and using MTP (which is enabled by default), as others already suggested. However, if you have debugging enabled, you can go a step further, and use the Vysor chrome extension to mirror your screen onto your PC and take an entire backup of your phone, through an application like Titanium Backup.
Good luck!
Did you try to connect mouse through OTG cable?

Help me recover OP3 data

Hi all!
I recently dropped my OP3 and now i have a black screen and touch screen doesn't work. The phone is still on and operating (i tried calling it from another phone and it works). I want to recover data but apparently i have usb debug off and i tried connecting a keyboard with an OTG but apparently i had to activate OTG from phone, otherwise it doesn't recognizes it.
Do you know any method to recover data?
My last chances are repairing the screen myself to avoid the assistence erase all the data, or transfer my motherboard to another OP3, but do you know any other method before these two above?
Thank you

Most likely the connector has become loose (since you have not said anything about the screen being broken) and you can try to reconnect it by yourself.
Another alternative is to see if adb is working and your PC is authorised. If so, you can use the 'adb pull /sdcard' command to copy your data to the PC.
Alternately, search with Google since I remember reading about a method to mirror your screen and then using the mouse to enable whatever you want.

I'll check the connector but the screen has some cracks (tho i've seen screens in worse condition then mine work).
And i can't use the mouse because OTG is not on, on other phones you don't need to give permission to use OTG but on mine you have to,

What about adb? That is the easiest.
I am not talking about connecting the mouse to the phone through OTG. I am talking about using the PC's mouse to manipulate the cursor to the point where you want it on your PC's screen where your mobile screen is mirrored.

I think you are referring to Vysor, but i can't use it with debugg off again. Edit: I see that there are other apps like that but for most of them you have to install them on the phone, i'll search a bit more tho.
As for ADB i tried before with another phone with debug off and adb doesn't see the phone, i'll try with my broken phone but i don't think it will be different.

Just now, I switched off USB debugging in my OP3 and connected it to the Laptop. While the command 'adb devices' does not find the phone, as soon as it is connected, it shows up as a storage device and I can open it and copy data. I think that for this to work, you should have enabled MTP option for file transfer.
Check this on your phone.
EDIT: Check THIS as there seems to be a way though I am not sure that it works on current Android versions since the file locations may be different. Read till the end.
My phone goes in charging mode when connected to pc, and pc doesn't see it.
Did you do that through recovery mode?

No. Tried it while booted.
Now I tried on recovery mode. Still I get it as a storage device and I can copy data.
So most probably your phone is stuck on charging and not on MTP.

I believe so, every time I connected it to pc i had to switch manually from charging to recovery.
I guess my best solution is to buy a screen replacement and repair it myself

Have you tried fastboot flash twrp recovery and then fastboot reboot to recovery
You can try usb c to hdmi adapter , connect to a monitor or tv.
I am not sure but worth trying!!!

From what i can remember, the recovery mode, accessible from the fastboot menu, has a usb access mode.
If worst comes to worst though, i personally have replaced the screen on my OP3, and its not as difficult as it seems or is made out to be. Took me max 4 hrs.

connect to a second display

since I have to save some data from the internal memory and the display is dead, is it possible to connect to a second display (for example a TV) via the usbc port (the one to which I connect the charger)?

To use adb with your device, you’ll need to enable developer options and USB debugging:
Open Settings, and select “About”.
Tap on “Build number” seven times.
Go back, and select “Developer options”.
Scroll down, and check the “Android debugging” or “USB debugging” entry under “Debugging”.

Code:
c:\platform-tools>adb devices
List of devices attached
c:\platform-tools>
Unfortunately the display is dead and I cannot follow these steps. Is there any other way to enable USB debugging?
pointing a flashlight at the display, I found that the phone starts in fastboot
unfortunately Mi account was not added to the phone

Is adb bugs on model SMJ200G (j2) common?

I investigated the ADB program. At How to Install ADB on Windows, macOS, and Linux, I am stuck at step 7 of the instructions for windows. I do not receive any kind of pop up in my SMJ200G phone (j2).
This step:
7. On your phone’s screen, you should see a prompt to allow or deny USB Debugging access. Naturally, you will want to grant USB Debugging access when prompted (and tap the always allow check box if you never want to see that prompt again).

Perhaps my PC's connection to the phone is buggy, not the cable, but the software? by software I mean Windows/PC not my phone.
btw does file AdbWinUsbApi.dll need to be installed?
Are the following applicable for a official device that have never been rooted:

Unable to detect the phone -win nor Lin
Hello guys
Something really extrange is happening.
My j2 prime -532G- can't be detected by Windows nor Linux.
The usb is working because it charges the phone, but I can't access the phone at all. I checked all the drivers in Win -google/adb and samsung- and in Linux libmtp/heimdall/etc.
I have tryed different usb -not the original one since i lost it-
Even when i start the download mode, nothing happens.
it there a way to root the phone without a PC? i have tryed also kingroot apk but it is useless.
Thanks
