My phone's screen is broken. I want to be able to use it using a PC (I just need to use two apps for a short while). I have a password on my phone. If I remember correctly, I have USB debugging enabled. I don't know if I had ever checked the option to always allow from this computer when the allow USB debugging modal pops up. I am trying to use scrcpy to control my phone from my computer. The phone is Samsung Galaxy J7 (2016).
This is what I have tried:
I downloaded adb from here. I downloaded scrcpy from here. I moved the adb files to a folder. I moved scrcpy files to the same folder, overwriting the duplicates.
I opened the command prompt from that folder (I'm on Windows). I connected my phone to the computer using a USB cable. As soon as I connected it, I ran the command adb devices -l. This is what I got:
List of devices attached 31002adf4e2c435f device product:j7xeltexx model:SM_J710F device:j7xelte transport_id:1 The I ran the following commands:
adb shell input swipe 600 800 150 900 300 (swipe to get to screen with password prompt) adb shell input text "[mypassword]" (enter my password) adb shell input keyevent 66 (press enter key) scrcpy This is what I got in the command prompt (after the last command):
INFO: scrcpy 1.17 < C:\Users\[User]\Desktop\New folder (2)\scrcpy-server: 1 file pushed, 0 skipped. 5.0 MB/s (34930 bytes in 0.007s) [server] INFO: Device: samsung SM-J710F (Android 8.1.0) INFO: Renderer: direct3d INFO: Initial texture: 720x1280 WARN: Device disconnected I am stuck here, with no idea what to do. I've tried using Vysor, but it also didn't work. I'd like to stick with scrcpy, unless there is a better option. Please keep in mind that I don't intend to transfer data; I want to use two apps (one of which is the Signal app, to transfer my chats).

Easiest way to control a touch-disabled android phone is to use OTG cables and a chromecast - You may be able to invoke chromecast mirroring via ADB, and the OTG cable can accept a mouse/keyboard if touch is broken too. Here is the cable you may need
