The paint on my Zenfone 6's side metal frame is starting to chip with small dots exposing the inner aluminium. I use my phone with a soft Silicone case all the time and have no idea how the paint could be chipping on the inside. Haven't dropped my phone either. Anyone else experiencing this?
That was the case with every aluminium body phone I've ever owned. It chips because such cases are sand magnets and as we all know sand's very rough. Once it gets stuck between phone and silicone, it starts scratching.
The "paint" is anodized aluminum and if you check jerryrigeverything you'll know it is scratched by razor blade at mohs hardness 5, so it must be below 5. bear in mind that sand is 7 so it must scratch.
