Touch functionality doesn't work any more.

My Apple Watch series 2 fell down and the glass part of the screen popped out. Also two of the flex cable connections (pins) got detached. There was no physical damage to the glas screen.

After attaching the flex cable connection (pins), the screen started working again.

But the touch doesn’t work any more on the screen, it doesn’ t respond at all.

I have rebooted the watch many times, this didn’t help.

Does anyone has an idea, what could be the problem? The screen ist still open, how can one glue this part of the glas to the cover. Below I am attaching the images.

Thanks a lot for your reply.
