As screen is not maintained anymore you should look for modern alternatives like tmux.

tmux is superior for many reasons, here are just some examples:

Windows can be moved between session and even linked to multiple sessions
Windows can be split horizontally and vertically into panes
Support for UTF-8 and 256 colour terminals
Sessions can be controlled from the shell without the need to enter a session
Basic Functionality

Dear BrowserStack User,

We are unfortunately displeased to announce that BrowserStack will be shutting down. After much consideration on our part, we have realized we were negligent in the services we claimed to offer.  In our terms of service, we state the following:

   [...] after the restoration process is complete, the virtual machines are guaranteed to be tamper-proof.

   [...] The machines themselves are in a secure network, and behind strong firewalls to present the safest environment possible.

   [...] At any given time, you have sole access to a virtual machine. Your testing session cannot be seen or accessed by other users, including BrowserStack administrators. Once you release a virtual machine, it is taken off the grid, and restored to its initial settings. All your data is destroyed in this process.

// selenium tests were failing because an element was not in visual sight
// we were using iScroll, so we couldnt scroll using normal functions
// how to fix? execute JS in your selenium script. initialize a new IScroll object(preferably similar to the actual initalization in the current script). Scroll to bottom.

var NavScroll = new IScroll('#nav-scroll', {
    mouseWheel: true,
    scrollbars: 'custom',
    interactiveScrollbars : true,
    tap: true,
    preventDefault: false
