Description

I am using a T-Deck Plus. Almost exactly every 30 seconds, the screen will turn off and back on and go back to the 'home' screen. This is annoying because if I am typing a message, the message I was typing is erased from the screen.

If I change the value of Light Sleep Interval from 30 to 300, the screen does not flash off and back on but the screen is still reset every 30 seconds.

Here is the log from the serial debug console:

INFO  | 20:31:05 201 [PowerFSM] Turning off screen
DEBUG | 20:31:05 202 [touchscreen1] action LONG PRESS(0/24693)
DEBUG | 20:31:05 202 [touchscreen1] Enter state: ON
DEBUG | 20:31:05 202 [touchscreen1] showing standard frames
DEBUG | 20:31:05 202 [touchscreen1] Showing 0 module frames
DEBUG | 20:31:05 202 [touchscreen1] Total frame count: 103
DEBUG | 20:31:05 202 [touchscreen1] Added modules.  numframes: 0
DEBUG | 20:31:05 202 [touchscreen1] Finished building frames. numframes: 5
INFO  | 20:31:05 202 [Screen] Turning on screen
DEBUG | 20:31:05 202 [Screen] Brightness is set to value: 130

This happen while both connected to USB and not connected to USB. This happens while typing and interacting and doing nothing.

I let it run for a few minutes and copied every time action LONG PRESS appears

16:49:34.667 -> DEBUG | 20:49:34 384 [touchscreen1] action LONG PRESS(0/24693)
16:49:54.682 -> DEBUG | 20:50:05 414 [touchscreen1] action LONG PRESS(0/24693)
16:50:34.700 -> DEBUG | 20:50:35 444 [touchscreen1] action LONG PRESS(0/24693)
16:50:54.717 -> DEBUG | 20:51:05 475 [touchscreen1] action LONG PRESS(0/24693)
16:51:34.710 -> DEBUG | 20:51:36 505 [touchscreen1] action LONG PRESS(0/24693)
16:51:54.715 -> DEBUG | 20:52:06 536 [touchscreen1] action LONG PRESS(0/24693)

You can observe that it appears to happen almost exactly every 30 seconds.

Thank you.

Spoke with my friend and his touch screen works, mine does not. It’s very possible that my touch screen is somehow broken from the factory. We’re going to try and reseat the ribbon cable and see if this fixes the issue.

wifi related?

I was having the exact same issue with my T-Deck Plus. Turns out, I accidentally left the factory screen protector on the touch display. I removed it and mine is now working fine. 🤦‍♂️
