Pocket watch. Isn’t that the intended purpose of the small pocket?

I’m running exactly that, with zero issues. I also have a secondary profile with Google Services Framework on it for the 2 apps I use that absolutely require it. It works great. Seriously, I’m never going back to a stock Android phone after this.

That’s what they are! I have a box full of leftover parts from years of home repairs, and I frequently store caps of opposite genders screwed together like this.
