anything that came out before 2011

the ps3 is retro then?

can’t you already do that? by clicking on the “new chat button” and pasting the phone number i can start the chat without adding to contacts; at least on whatsapp business that works

Get a cheap computer and connect the tv to it; get a mouse and bluetooth keyboard or an air mouse if your want to; install kodi perhaps, or just have your bare desktop. Problem solved

Disconnect the tv to wifi too.
