Pressing the “/“ or “t” on a keyboard with a mobile device brings up the chat menu, however the textbox is not focused automatically as it is on Windows 10 Version and Java.
Steps to Replicate
Get a mobile device with a keyboard.
Press the “/“ or “t” key.
Watch as chat is opened however you can’t type without clicking to focus the textbox.
Can confirm, also doesn’t work for pressing t when opening chat.
