I preordered my 6P on day one and I've been mostly happy with it since. I keep it in a fairly protective case at all times, and I also have a tempered glass screen cover on it. However, I recently removed the case to wipe it down, and a tiny piece of glass from the corner of the front display (see the attached photo) fell off. I have no clue how this happened, since my phone is usually in its case for days at a time, and I'm extra careful not to drop it. It only has one other nick in it, and I'm not sure how that happened either. I was initially comfortable with the build quality of the 6P, but now I'm really worried that even if I continue using it carefully, it will fall apart. Has this happened to anyone else?
