update: as mentioned above, the lg v20 was not affected. But after last week's upgrade to oreo, the same thing is happening.

this one is not affected:

Folks, if you're inside 'adb shell' and press the UP key, does it show the previous command in history or do you get this?

root@localhost:~#
root@localhost:~# adb shell
greatqltecs:/ $
greatqltecs:/ $ ^[[A|^[^[

@diehard88

actually, the same probl3m.

[diehard88]

solution: according to Leonid Plyushch@xeffyr, if you have root, then you can do setenforce 0 and adb in termux-ubuntu.

why: Oreo has problems with tcsetattr(a, TCSAFLUSH, b); 
this thing can't be changed without recompiling binary that use it.
