Activating USB-debugging blindly - Galaxy S6 Q&A, Help & Troubleshooting

Hi,
After my S6 dropped flat on the floor it's screen went gradually violet and then black. Now I'm left with working digitzier but I can't see nothing. In order to access my phone I'd like to connect keyboard via OTG and access developers settings and then enable debugging so eventually I could connect S6 with my PC via Vysor app. Would someone try to do it on their phone and then post the keys combination here, please? It'd be much appreciated.
Thanks in advance.

if this doesnt pan out, try a MHL adapter. also, knowing what version of android you were on before the screen went ka-put would help for the key combos

I'm pretty sure that you cannot use MHL with S6. The version was 7.0 I think.

ok, sorry. i wasnt sure if it would work or not, just wanted to throw it out there

Problem solved. I decided to share the solution in case someone has a similar problem. Long story short: take screenshots with the key combination specific to your phone and view them on your PC so you know the approximate position where to tap on your screen to select some option. I found that one comment the other day, posted under one of the videos on how to control a phone with a broken screen. Since I'm a new user here I cannot share the external link to the video.
The author of the comment was Adam Cepnik so all credits go to him for this simple, yet genius solution. Here's the comment:
"If your screen is black, but you can control the phone by touchscreen, connect the phone to your PC. Then try to unlock your phone (it will take a few tries, but it is possible). This should unlock your phone's internal storage so it should be visible from the PC. Then find out how to make a screenshot. The screenshots can be found somewhere in the internal storage via PC. Then you can see a picture of the phone's screen and attempt to control the phone according to the screenshots (take them everytime you touch something). It is slow, but it can help you to enable the debugging even with black screen."
Hope someone will find it helpful in any way.

[Completed] Impossible is not a solution

Ok, I've been at this for two days now. I'm trying to get an S4 to display on a computer screen so it can still be used until the owner can afford a repair.
The screen isn't cracked, but the LCD and Digitizer are completely broken. The phone still functions when connected via USB.
- side note, my phone is currently in the same condition but before it went down I had it rooted and put into debugging mode. I was able to accomplish this feat without an issue, from my phone.
Okay, so the phone I'm currently trying to get this to work on:
1. Isn't rooted
2. Screen is black and no touch response
3. Not in developer mode, not set for debugging
4. Computer can recognize phone via USB
5. Able to still install apps from the goggle play store via the website
Goal: get it to be able to mirror/display on a computer
I've seen posts on the internet stating everything from impossible to no it's possible but we won't give you the details.
These things are basically handheld computers, even without it being "rooted" i should be able to access it in some way from a computer to put it in debugging mode even if i have to program it in myself. Which is why "impossible" is something I cannot swallow.
Any tips, advice or a point in the right direction here would be appreciated. Thank you.
-currently im trying out this Mobile Go program even with the phone not in debugging.
-I feel like there has to be a way to force the phone into debug mode even if you cannot physically use the touch screen or see anything.

Can I authorise ADB with a broken screen that does not show anything?

Hi all!
Unfortunately, I dropped my OP6 at a gig last night and the screen is decimated, cannot see anything and I cannot interact with it.
I took some photos and videos that I really want to keep but as wifi is off Photos will not back up.
My hope is to switch on wifi using adb, not sure if that is even possible but before I can try this I need to authorise adb on the device, which I cannot do with the screen being in the state it is.
I can see the device when issuing adb devices but of course it tells me it is unauthorised. Is there a way I can authorise adb on this phone to allow me to switch on wifi?
All of the research leads me to solutions where the digitiser is broken but the screen is still visible and the issue is solved using OTG adapter, this solution will not work for me.
Any feedback is very much appreciated!
Thanks!

If you have the developer options already activated and have already used adb with your phone in your computer I think it authorizes automatically.
In my case I don't have to authorize my phone every time.
If you haven't done this I think there aren't much options but to replace the screen
Hi There,
That is my problem, I have not yet used ADB with this device so I had not yet authorsied ADB on the device.
So far I have not uncovered a way of doing this, it looks like I will be losing a lot of photos and videos

Galaxy J3 2017 Black screen, can unlock with keyboard and unsure what to do next.

Hi all,
Firstly I've looked on all black screen help pages but none of them help. Last week my galaxy j3 2017 model died. The screen is just black, but the phone 'works', and by that I mean if I ring it the phone rings, notification sounds still happen but screen is still just black. I've charged it, let it die, tried all combos of reboots but nothing. Using an online guide, if I plug a USB keyboard in and tap my code followed by enter I hear the phone unlock (yes it has a pin screen lock). I then tried to plug into a laptop, but using Windows explorer, my phone is there but going into the phone, the folder is empty. I'm guessing this is because I can't enable file transfer etc on the phone. I'm at a loss wgag I can do. Samsung said I can take it to a shop to be fixed, but I have a few weeks of data and files I want to try and rescue first. Can anyone offer any advice please?

your screen is dead on your phone and your not going to be able to get the data from your phone. All you can do is send it in to samsung.
Ok, thank you. At least with this confirmed I can just get it fixed and hope a file recovery tool may help. Thanks again.

If you haven't taken this for repair yet then you can confirm a dead screen if you see nothing at all when restarting the device.
However it IS possible to rescue the data. There are various ways to do this with a blank screen. Obviously the easiest is via MTP. There is also Smartswitch.
Adb is also an option.
This would be trial and error until you hit the right spot to enable usb transfer.

Broken AMOLED, digitizer good. Is data recovery a possibility?

Dropped my op6 flat on its face the other day:crying::crying::crying:
Anyways.. I'm trying to get the data off of it before i attempt the feat of replacing the screen. Like the title says, the digitizer is good, l can unlock it by remembering the screen lock, but I fumbled all yesterday trying to cast my screen. I had slivers of screen I could see there, just couldn't get it to send. No usb debugging and I obviously didn't turn usb mode to file share. Please help if you can, thanks.
If you have TWRP installed, reboot to recovery and just connect your phone to your PC via USB - MTP should be active by default. Inputting the decryption code if you can't see much of what you're doing can be a problem, though.
If you don't have TWRP installed however, you can try using scrcpy (just search for it on Google and you should find its GitHub repo with instructions). It uses adb to run, meaning it requires usb debugging to be on, but the good thing is, as long as your phone is unlocked (not on lockscreen), you should receive a prompt asking to enable debugging just by running the scrcpy executable. Since said prompt is always in the center of the screen (screenshot attached), and you only need to click 2 separate things on there (always allow checkbox & the allow button) to get things going, you should be set fairly quickly. Hope this helps!
Thanks for your reply, this did work and it was very simple.

Motorola G8 Power: Accessing data without opening lock screen

Hi. I just want to confirm the following first:
- The phone is mine.
- My fingerprint is stored on the phone
The screen got cracked so I had it lying around for 6 months before I got screen replaced. Now no pin code I have goes past the lock screen to open up the phone. I have set it to fingerprint unlock too.
My question is:
Can I access the data without opening up the phone? Going into some sort of developer mode on the phone?
Is it easier to bypass the lock screen and go to the fingerprint option?
I just need some pictures I have on the phone. The phone itself is not important for me to use anymore.
In advance thank you for all the help and if this is not in the right section please let me know where I should go with this.
If phone supports OTG then it should be possible to access user-data stored on phone connecting PC and phone via an USB-C OTG cable.
Thanks for your message. How will I know that the phone supports OTG?
EDIT: Seems like my phone does not support OTG. Mostly Samsung and LG.

Thank you for finding this out. What would be the software needed to use to get the data extracted?
Once connection is established you should see the Android's /data partion on Windows computer using Explorer.

Without needing to open up the Motorola phone?
Phone of course must got successfully powered on: Then it's detected as any USB-Host device, too.
I have ordered the OTG cable. It will arrive tomorrow. I will give you an update on how it worked here.
Thank you.
I just talked to Motorola support and their view was that it would not work. I will still try this but not sure if this has to do with the fact that the phone is in lock screen mode?
