Can I use an Android from a PC ?
2026, Febrer - Huawei Mate 20, model LYA-L29 -> taca grisa a la pantalla ...
Prompt Gemini :
I have an Android Smartphone who got hit and now a dark cloud is extending slowly on the screen.
Is there any way I can use it remotely as a computer (or a phone) ?
That "dark cloud" is a telltale sign of an internal ink leak (common in OLED screens) or a bleeding LCD.
Since the ink spreads over time, your screen will likely be completely black soon.
The hardware solution (USB-C to HDMI)
If your phone is a flagship model (like a Samsung S-series, Google Pixel 8 or newer, or OnePlus), it likely supports DisplayPort Alt Mode.
How it works: plug a USB-C to HDMI adapter (or a multi-port hub) into your phone and connect it to a monitor or TV.
If you use a hub with USB ports, you can plug in a standard mouse and keyboard to navigate if your touch screen is also failing.
The software solution - scrcpy
If your phone doesn't support HDMI output but you have "USB Debugging" enabled in the settings, you can use a free, open-source tool called "scrcpy".
What it does: it mirrors your phone screen to your PC/Mac via a USB cable and allows you to click and type using your computer's peripherals.
Why it's great: it's lightweight and requires no app installation on the phone itself.
How to install scrcpy
On Minie, use "Software Manager" to get Version1.21-1 {20260209}
This application provides display and control of Android devices connected on USB (or over TCP/IP). It does not require any root access.
This package contains the client (desktop) binary.

WARN: Killing the server...
Old version of scrcpy - Android changed its internal code (specifically how it handles the clipboard and screen mirroring),
which is causing those java.lang.NoSuchMethodException errors.
To fix this, you need to update "scrcpy" to at least version 2.0 or higher (the current version is 3.0+).
Lets use snapd to install latest "scrcpy" - use these commands :
sudo apt update
sudo apt install snapd
# You may need to log out and back in, or restart to refresh your PATH
sudo snap install core
sudo snap install scrcpy
Lets go :
sebas@minie:~$ sudo apt update

Cursor is captive in Android App screen :
The "Magic" Keys
Press Alt (the left one): By default, this is the "shortcut modifier" in scrcpy.
Alt + f: Toggles full-screen (if you are in it).
Alt + g: Toggles the "grab" mode (this is likely what you need to release the mouse).
The "Emergency" exit: Just press Ctrl + c in the terminal where you launched scrcpy to kill the process and get your mouse back instantly.
How to prevent this "Captivity"
Since you are using a MINIE and don't have a SIM card, you need uhid, but you don't want to be a prisoner of the window.
You can run scrcpy with a "hover" configuration so it only grabs the mouse when you actually click inside the window.
Try launching it like this next time:
scrcpy --keyboard=uhid --mouse=uhid --shortcut-mod=lctrl,lalt -> "Alt" + "Tab" to exit App screen
Et voilà !
Remote Access Apps
If your screen is still partially visible and touch still works, install these immediately before the "cloud" takes over:
Method Best For... Requirement
TeamViewer / AnyDesk Remote control from anywhere. App must be installed and "Unattended Access" set up.
Google "Find My Device" Emergency lock or wipe. Logged into Google account.
KDE Connect / AirDroid File transfer and SMS from PC. Both devices on the same Wi-Fi.
Immediate Next Steps
- back up your photos: connect the phone to a PC via USB immediately and set the USB mode to "File Transfer" while you can still see enough to tap "Allow."
- unlock the SIM: if you restart the phone and have a SIM PIN, you might get locked out of the network. Disable the SIM PIN now if possible.
- check for "Smart Lock": if you are at home, ensure your home is a "Trusted Place" in settings so the phone stays unlocked, making it easier for recovery tools to access it.
How to disable SIM pin
Step-by-Step Instructions
- open Settings.
- go to Security (on some EMUI versions, it might be under Security & privacy) / search for "lock sim"
- tap on More settings.
- tap on Set SIM 1 lock (or Encryption and credentials > Set SIM lock depending on your specific update).
- toggle the switch for Lock SIM card to the OFF position.
- crucial: You will be prompted to enter your current SIM PIN to confirm the change.
How to keep phone unlocked
Use "Smart Lock" (best for Home)
This is the most reliable method. It keeps the phone unlocked as long as it is in a "trusted" situation.
- go to Settings > Security > Smart Lock.
- enter your current PIN/Pattern.
- choose Trusted places: Add your home address. The phone will stay unlocked as long as you are there. {???}
The "Stay Awake" developer hack
Since you already enabled Developer Options, you can use a "god mode" setting that prevents the screen from ever turning off while the phone is charging.
- go to Settings > System & updates > Developer options {Redmi 12 : Settings -> Additional Settings}
- find and toggle Stay awake (Screen will never sleep while charging).
- keep your phone plugged into your PC or a wall charger. The screen (and the internal "session") will stay active indefinitely.
How to enable "Developer Options" @ Huawei Mate 20
- open Settings
- scroll to the very bottom and tap System & updates (or just System on older versions).
- tap About phone.
- find the Build number and tap it 7 times quickly.
Note: You may be asked to enter your lock screen PIN/Pattern after the 7th tap.
- you will see a toast notification saying: "You are now a developer!"
- go back one screen, and you will now see a new menu item called Developer options.
Critical Settings for Remote Use
Once you are in the Developer options menu, toggle these two settings immediately:
- USB Debugging: this is mandatory if you want to use tools like "scrcpy" to control your phone from a PC.
- "Allow ADB debugging in charge only mode": Huawei phones often block debugging unless this specific toggle is also turned on.
Redmi 12 : remove initial "select a pattern"
Easy :
- Settings -> "Screen Lock" -> "Fingerprints, face data and screen lock"
- set "Screen Lock" to "Off"
Redmi 12 : remove "sleep"
Also "Lock Screen" -> Sleep -> "Never sleep"
Redmi 12 : power on sequence
- message "USB debugging is ON"
- message "USB - no data transfer" -> select "File Transfer"
