I'm using EVPlay (Version 3.1) with a 2025 Rivian R1S Gen 2. When I first enter the vehicle, the screen starts at the stock Rivian UI. Then when I press the EVPlay button, the screen switches over to the EVPlay Carplay UI as expected.
But every single time, the first switch to EVPlay results in the touch screen being unresponsive. Even if I wait some time before / after triggering the switch - it's still unresponsive.
I'm able to fix the issue by switching back into the Rivian UI, waiting a few seconds, then switching back into EVPlay, then waiting a few seconds. And my 2nd switch into EVPlay restores touch functionality. But this is highly frustrating when I have to do this every single time I enter the vehicle.
I have performed the hardware fix to improve switching reliability. But that did not resolve this specific issue. I've been experiencing this ever since I first received the device months ago. I'm just now getting around to troubleshooting it.
Is there a way to get the touch input working on the first attempt EVPlay is activated when entering the vehicle?
Summary of the steps I have to take every time I enter the vehicle to get it working:
Enter Vehicle with Rivian UI on screen
-> wait ~5 seconds
-> press the EVPlay button to switch into EVPlay UI
-> wait ~5 seconds
-> touch doesnt work in EVPlay UI
-> press the EVPlay button to switch into Rivian UI
-> wait ~5 seconds
-> press the EVPlay button to switch into EVPlay UI
-> wait ~5 seconds
-> now everything works as expected
