I’m experiencing the same issue, but it’s affecting the entire right edge of the screen, and it’s really frustrating. Here’s what I found: I removed the screen protector from my Pixel 3a, where it had large bubbles all along the right edge. When I applied that same protector to a different phone, the bubbles didn’t appear at all.
I even tried reapplying the protector to the original phone, rotating it 180 degrees to see if the issue would shift sides, but the bubbles still formed along the right edge. This makes me suspect there might be a flaw or inconsistency with the display on the Nothing phone itself.
