EDIT: Managed to get into the phone using adb and the shell command "locksettings clear --old xxxx".
Then connected a mouse using OTG adapter to turn off Second Screen app, another reboot and it's back
EDIT 2: Noticed that secondscreen didn't restore it do the DPI that I used to have, which is not much of a problem, but it also locked the screen refresh rate to 60 Hz regardless of if it's in battery saving mode or not. I really like 90Hz, so any ideas on how to get that back?
Hi, I just wanted to try out my new HDMI adapter and the desktop mode of my OnePlus 7 pro. I enabled dekstop mode and installed the app Second Screen and elevated privileges using adb.
Connected the phone to the monitor, which worked very well. Then wanted to see if SecondScreen could enhance the experience. Changed some settings, including locking apps in landscape. Then rebooted as requested.
Upon reboot, also the enter pincode screen is in landscape, and it doesn't react to touch input. So I cannot unlock the device and get into any apps.
My question is, how to undo the changes made by SecondScreen? At least the ones pertaining to landscape mode, so that I can enter the device and undo all changes. I have a hunch they won't go away simply by force removing the app using adb ..
Very grateful for any help, as I can't use my phone.

This is odd. I have not changed my TWRP version (2.8.1.1) in a very long time so the problem below is not triggered by flashing a new recovery image-- or anything else for that matter. Today I went into recovery mode and:
The tablet turned on the touchpad interface (a mouse cursor appeared)
The touch screen interface is off.
The keyboard interface is off.
I tried to click on everything but although I could see a visual indication, there was no change to the chosen onscreen menu "button."
Removing tablet from keyboard dock does not help.
In desperation I held down the power button hoping to force a hardware restart. But TWRP went into lock mode.
I can't access the swipe motion to unlock.
I can't force a reboot.
I tried ADB to see if I could do a command line reboot.
Windows 10 Device Manager shows the ASUS device in the list.
Windows 10 PC can display the filesystem on the tablet.
But command "ADB devices" never shows the tablet. (Empty list.)
Weird!
Is my only choice to run the battery down?

The problem condition suddenly cleared. It's as if the tablet knew I was complaining to the XDA community.
One hour after the problem first appeared, I tried plugging the USB into the PC again. The touch screen spontaneously turned on. I was able to swipe the unlock and perform the cache clear. And performed the reboot.
You don't have to waste energy guessing what happened. But if any of you are convinced you know why this ocurred, I'd love to know so I can prevent a recurrence.
Is there a later compatible TWRP for the TF101? I couldn't find one.
A while back, My old Stylo 2 stopped working due to a very strange (I assume hardware-related) bug that made the phone constantly press the same spots over and over and over, and the screen was entirely unresponsive otherwise. Only those few spots ( 1. About 25% up the bottom right side, 2. The very top right corner, and most prominently 3. Just right of the multitasking button, within its 'hitbox'.) have any effects on the screen at all, and I cannot find places on the screen that are 'touchable' due to the multitasking button being hit over and over and it constantly switching me between apps.
More than anything, I just want to change my USB mode to file transfer to get my pictures off the phone, but even as easy as that is in Android 7 (pull down the top menu, select USB settings, change to file transfer right?) I can't even get the top menu down most of the time, let alone get to the USB settings. On the rare occasion that I do get all the way there, either the multitasking button starts acting up again or the screen stops responding to everything altogether, making the one thing I need to select un-selectable. Much to my dismay, it also seems that I have USB Debugging turned off (I honestly have no idea why or how this was turned off, as I use ADB frequently), so I can't even use ADB to get a screen control app to run. Are there any ways to either force USB Debugging to be on via console (Win8) or otherwise, or control the screen and disable touch without the need for a third-party app?
Yes

Yes, but I'd appreciate a thanks for the solution! I give and give ...
First, what model number is your Stylo? For instance I have the Cricket variety (H634). Once you figure that out check out my link below with particular attention paid to the "how to enable usb debugging via dialup" step. I just tried it with my Stylo (H634), works great. The link pertains to the LG G6 but it will work on your LG Stylo as well.
https://forum.xda-developers.com/tmobile-g6/how-to/frp-unlock-lg-g6-using-headphone-jack-t3616166
Or just try this ...
Dial *#546368#*_ _ _# (Field Test Mode). Enter your devices model number in the three blanks. Mine for instance would be *#546368#*634# (H634 being the Cricket model number). Go to SVC>LDB> Enable usb debugging
Happy USB'n!
Short time after MIUI 12 update touch started to behave erratically.
While it worked I disabled Z Launcher I used, uninstalled bunch of apps, enabled showing of the touch on the screen, but did not backup photos.
Now touch screen indicates touches only on the left edge of the phone and I am unable to unlock it, and enable file transfer mode.
I want to factory reset the phone as the last resort, but would like to download photos first. Any idea how to achieve this?
I have USB C cable to attach to Win10 PC, but no files are shown (likely, because of not enabling file transfer mode
My phone's screen was broken, so the touch sensor (capacitive) sensing constant phantom touches, which prevents to do anything with it, even with mouse connected on OTG.
I can't connect on ADB, as once i've allowed my PC to always connect to it, yet asks for a confirmation at every connect, which i can't grant, as if i unlock the phone with fingerprint, the phantom fingers instantly tap the dialog away.
I can connect with fastboot, but it's useless.
My next idea is to disconnect the screen ribbon cable (xiaomi "engineers" were so smart that the display and the digitizer are on same cable... which is weird, as redmi 7 had seperate cables and this redmi note 7 have one), and buy an MHL type-c -> HDMI-OTG adapter, and connect it to TV, and the mouse, then i can access my files... however i doubt that it will work
Any tips how to hack it or something? I'm thinking about that it maybe possible to electronically disable, or "burn out" the touch sensor without disconnecting the screen ribbon. Is that possible? Perhaps the cleaning of screen would kill the phantom?
Any help?
I would like to help you but never had to deal with such a problem.
But let's try:
1. What do you want to achieve? Do you want to backup your data?
2. The phantom touches are instantly and do not stop?
3. Don't know if that works, but... Is the mouse connected to OTG always on the same place? Like does it appear on a fix default position on your screen every time you plug it in or does it remember its last position (or is it random)?
If you know that you could maybe try to detach the display and use the mouse to enable your adb connection constantly. And if that works you could use scrcpy (screencopy. Find it on github) to show your devices display on your computer without having to use your real smartphone display.

Its a quite common problem, however the most people just buy a new phone, and dump the broken one.
I want to backup one application's data particularly, yes.
Phantom touches are constant, always at the menu buttons.
I cant connect otg mouse and to adb at the same time... 1 usb only.
Why cant i just authrnticate myself through adb?

I don't know. What exactly happens if you try that?
You connect your phone with your computer and run some adb command (e.g. "adb devices") and then it asks you to authenticate, right?
And then?
Another question which I think you'll answer with "no": Did you unlock your bootloader?
I just cant do it, and didnt fide any help for it on google.
If i connect it, and list the adb devices, i see "unauthorized" and a dialog pops up on the phone to allow adb connection, but as soon as i unlock the phone the dialog goes away as the phantom touching the menu buttons...
No, the bootloader is not unlocked, else if would be able to save with twrp. I can unlock it with fastboot, but it does a factory reset on unlock...

I have another idea. If you refer to the menu buttons you refer to the home, back buttons right? If your phone support it (and phantom touches allow it) you can go to setting -> System -> Gestures -> System navigation -> gesture navigation. Then click on the setting next to "gesture navigation" and turn of navigation hint.
Whatever those phantom touches are touch now – it won't be any of those menu buttons since they disappeared.
Now, hopefully adb authorization works.

As i wrote, i cant do anything on UI, as the phantom always touch back to the menu, or to the photo app, which i cant even pull out from quick access due to the phantom.
Having a ghost touch issue, it's probably not a problem with the software, but it's a hardware problem with your display and the way it's housed inside the chassis of your phone. If you're an engineer and happy taking electronic devices apart ( and have all the required specialty tools ), then you might fix the issue by simply disconnecting the screen from its data connectors for a while and then reseating the screen.

It's very hard to do anyting on phone anything blindly...
Hey, so my phone's screen recently broke, and it was still working perfectly in Samsung DeX mode. However, I made the mistake of disabling it because something I wanted to do required normal screen mirroring. Now, when I plug the phone through HDMI, I see a padlock on the screen, which normally requires me to enter my pattern to unlock the phone and have the screen mirror normally (but the screen and seemingly touch aswell are broken).
- Samsung S20 FE
- USB Debugging is disabled, so i cant use scrcpy
- I am able to feel vibrations when using a mouse, so maybe there would be a way to enter it blindly, but the pattern is too complex for me to do that
- I don't think I have a normal PIN but I don't recall, some people said pressing space twice on a keyboard then entering it could help, no luck
- I'm was able to see the device once in sideload mode, probably through recovery mode? (screenshot below)
- I currently see the device as unauthorized (2nd screenshot)
I'm pretty much open to any way of doing this, even disabling the pin would be okay.
Thanks in advance!
Managed to fix this using a windows drawing pen, finding where the dots for the patterns are located with vibration, and mapping them on a piece of paper.
another way would be connect TV or monitor with HDMI adapter and connect usb mouse / keyboard

The thing is, the pattern doesn't show on the external display.
All you see is a grey screen with a padlock and the time.
If you have a PIN though, that does work cause you just have to hit space twice, type it in then hit enter. Easy even if you can't see.
