Is this normal XZ3 build quality?

There ARE gaps though, but i'm guessing they were intended

Due to production tolerances and different thermal expansion coefficients of the materials there will always be a gap, that's intended.

The XZ3's build quality -at least on my device- is top notch.

My phone has the gaps also. Despite this, it's waterproof. I usually take mine with me in the shower, wash it, and take underwater videos - i miss the touch block small app when recording underwater. Gets pretty hard to maintain the video rec on...
