When you start Android Terminal Emulator, it creates a terminal connected to some tty ( This issue has been discussed in this thread: Terminal emulator size after upgrade Android 4.3<\/a>. There is a link to one possible solution of the issue: Android root shell<\/a>. In my opinion, it’s quite overcomplicated: it The solution is based on maintaining a special file containing all superuser ttys and making Android Terminal Emulator notify each tty from that list.<\/p>\n The first part<\/strong> can be done via editing This code is executed each time new mksh is emerged. It makes mksh do the following:<\/p>\n The second part<\/strong> requires patching Android Terminal Emulator. The patch is available here<\/a>.

Here<\/a> is the explanation of the new SuperSU architecture from its authors.<\/p>\n\/dev\/pts\/0<\/code>, for example). When you type su<\/code>, the superuser process you get is connected to another tty (\/dev\/pts\/2<\/code>), which the terminal emulator is not aware of. After that, when you invoke or hide virtual keyboard, rotate your device, the terminal emulator notifies the original tty to change its size, but not the one, which the superuser process is connected to. This issue makes terminal emulator almost unusable.<\/p>\nPossible solution<\/h2>\n
\nrequires running another daemon (pts-daemon<\/code>) and using a wrapper process (pts-shell<\/code>). So I developed another solution, which is much simpler and is not dependent on the application providing superuser access.<\/p>\nMy solution<\/h2>\n
