echo -e -n "\033[2J" in my /system/bin file as 'clear'. Its working now but same problem remains. Cursor doesn't go to top left of the screen.
You do not have a real terminal... (edited by neo). There's entire categories of things it cannot or will not do. Most people, once they root a machine, install sshd so they can login with a real terminal and do real things.

reptyr
reptyr(1) General Commands Manual reptyr(1)
NAME
reptyr - Reparent a running program to a new terminal
SYNOPSIS
reptyr PID
reptyr -l
DESCRIPTION
reptyr is a utility for taking an existing running program and attaching it to a new terminal. Started a long-running process over ssh, but
have to leave and don't want to interrupt it? Just start a screen, use reptyr to grab it, and then kill the ssh session and head on home.
reptyr works by attaching to the target program using ptrace(2),
redirecting relevant file descriptors, and changing the program's controlling terminal (See tty(4)) It is this last detail that makes rep-
tyr work much better than alternatives such as retty(1).
After attaching a program, the program will appear to be either backgrounded or suspended to the shell it was launched from (depending on
the shell). For maximal safety you can run
bg; disown
in the old shell to remove the association with the program, but reptyr will attempt to ensure that the target program remains running even
if you close the shell without doing so.
OPTIONS
-l
Instead of attaching to a new process, create a new pty pair, proxy the master end to the current terminal, and then print the name
of the slave pty. This can be passed to e.g. gdb's set inferior-tty option.
-s
By default, reptyr will move any file descriptors in the target that were connected to the target's controlling terminal to point to
the new terminal. The -s option will cause reptyr to unconditionally attach file descriptors 0, 1, and 2 in the target, even if the
target has no controlling terminal or they are not connected to a terminal.
-v
Print the version of reptyr and exit.
-h
Print a usage message and exit.
NOTES
reptyr depends on the ptrace(2) system call to attach to the remote program. On Ubuntu Maverick and higher, this ability is disabled by
default for security reasons. You can enable it temporarily by doing
# echo 0 > /proc/sys/kernel/yama/ptrace_scope
as root, or permanently by editing the file /etc/sysctl.d/10-ptrace.conf, which also contains more information about this setting.
BUGS
When attaching to some curses programs, they will not redraw the screen right away, and a ^L or similar will be needed to force a redraw.
Similarly, after attaching to certain programs, the old terminal will be left in an odd state, and a clear or even reset may be required
before the old terminal is usable again.
Attaching to rtorrent (and probably some other apps) doesn't work right (rtorrent stops accepting input) (The problem is that rtorrent is
using epoll to poll stdin, and we don't update the internal reference that the epoll fd has to the old tty).
Attaching to a process with children doesn't work right. This should be possible to fix -- I just need to ptrace each child individually
and do the same games to it.
Attaching a less(1) process doesn't work if you have a .lessfilter file, as less leaves around a zombie child in this case. This could be
worked around.
Bugs should be reported to the author (see below) or via the issue tracker on GitHub.
