Is your feature request related to a problem? Please describe.
When I connected my old Samsung phone, enabled USB debug and developer mode. I then run:
scrcpy in a console and I received this error:

~$ scrcpy
INFO: scrcpy 1.18 <https://github.com/Genymobile/scrcpy>
/usr/local/share/scrcpy/scrcpy-server:...shed. 8.7 MB/s (37330 bytes in 0.004s)
error: closed
ERROR: "adb reverse" returned with value 1

Describe the solution you'd like
I hope the old phones could be supported like the modern phones.
There are huge amount of old phones which are still capable of doing something.

If it's Android >= 5, it is supported. If it's Android < 5, it's not and will never be: #98 (comment)
