Last year my phone’s screen broke in a way, that made it register inputs even if nothing was touching it. Any reasonable person would simply get a new phone, but I am not reasonable and also didn’t have any spare cash back then. So here is a short post about how I used my phone without a screen for around a month.
#Making it Somewhat Usable
The screen wasn’t completely unusable, and I was even able to text to some extent, but it was getting noticeably worse as the day went on. Once I got home in the evening I battled with it to turn on USB debugging and tried to set custom resolution using adb↗:
Thanks to the square aspect most of the area with ghost touches was cut off. Using scrcpy↗ (a tool for controlling Android from pc) made inputting things easier, but after a few days of using it like this, even that became too much of a chore.
#Disabling the Screen Completely
Since my phone was rooted, I tried looking for some better solution on XDA↗ and I found a thread (couldn’t find it again), whose author mentioned disabling some drivers and even if their exact solution didn’t work it made me realize, that Android is just Linux under the hood.
rm /dev/input/* as root and voilà, the touch stopped working, and so
did all the buttons…. After rebooting the phone I started deleting inputs
one by one until I found one, that corresponds to the screen (event2 in my case).
By placing the following file inside
/data/adb/service.d, so it gets executed by
Magisk↗ on boot, we can permanently
disable the touchscreen and dim the LCD, since we don’t need it.
#Authorizing ADB on Another Computer
If a screen is non-functional it is obviously very difficult to use it to
allow debugging when we plug the phone into an unauthorized PC. Thanks to
thread I found out, that all I had to do to enable debugging on my laptop was
copy the contents of
It is not desirable to need a pc for answering calls, but my earbuds had the ability to accept via double-tap, so I always kept them within reach.
The only thing aside from calls, that I needed my phone for was my banking app,
which did not allow screen recording so
scrcpy would only show black screen.
Thankfully there is a
Xposed module↗ made
precisely for solving this issue.
The positive thing was, that whenever I would usually look at something on my phone to pass time, I had to do something meaningful instead. And although I don’t recommend breaking your phone, it was definitely a refreshing experience.
