Hi,

Thanks for the bug report. Couple of questions to clarify the issue since I'm having trouble reproducing that:

  1. What do you call sleep mode? Turn off and on the screen? Put the app in background? Do you have to wait a specific time?
  2. Is the debugging session always running when you do that or it stops before the app crashes?

The debugging session should stop if you turn the screen off (maybe what you call sleep) but I haven't seen issues when returning to the app (and moving tabs) after that.

Hi,

1 Yes, I press on sleep button and one more time to wake up device. Try to change tabs fast about 20 times or more, it does not crash instantly or on the first change. I think one 1 - 5 minutes is enough for this bug. 2 The debug session “Stop” after I pressed on the power button.

I'm able to reproduce this. Here are the steps.

  1. Download the sample
  2. Debug the app on a device
  3. Once the app has launched, press the power button to lock the device.
  4. The debug session will disconnect (as expected)
  5. Unlock the device and the app should be in the foreground.
  6. Tap between the 3 tabs quickly for about 30 seconds. I used two thumbs.
  7. Eventually, the app hangs and has to be force quit.

I did not get any meaningful info in the device logs while attached with Console running. @VincentDondain Can you try and take a look?
