Charge 3 Screen flicker dead pixel and connection issues

[Speed_Runner]

Hi, my Charge 3 SE started to acting weird today. During charging it started to vibrate periodically and the screen keeps toggle between random pages.

I took it out of the clip, the screen is not responsive to swipe and I notices couple line of dead pixels as it keeps jump between screens. It is some what responsive to squeeze, which make it a lot harder to do the 8 second reset.

After couple attempts, I finally were able to get to the loading bar screen. But the screen toggle come back as soon as it restarted. I tried to restart it couple times, and the eventually I saw a smiley face instead of loading bar. After that restart, the toggle issue is gone, and the screen become responsive again.

However, dead pixel line still exist, and It does not sync to my phone. Last time the app connected was 10 am today. I tried the switch watch face trick, but that was not successful. That app page is currently stuck in "Switching..." and preventing it from sync to the phone.

As soon as I put it back to the charging clip to do a reset, the crazy screen toggle will come back.

The green light is always present when near skin, so no issue there.
