For the Tele a chat Trophy in Stray, you’ll have to browse through all of the TV channels. To do this, find a TV that is on and press the nearby remote until the trophy triggers.
The first TV we found is in Chapter 4. To reach it, head to Grandma then use the nearby crates to climb to the top of the building with Heptor.
You’ll then need to jump to the building diagonally from him with the vending machine on it. Climb up the crates to the left of the vending machine to reach the roof.
This roof will have the TV on it. Interact with the remote on the couch and flip through the channels until the trophy pops!
