I’ve written before that for the OnePlus 5, the official protector is what I recommend. And for the Sony XZP, Banana’s soft film. Problem with soft film is it deforms easily and gets dirty fast — you’re basically replacing it every month. Which is when you start missing glass film. Shame that glass film on this thing always leaves a white edge. Sure, there’s white-edge oil, but it doesn’t last — two weeks tops and it’s gone, time to re-oil. And the stuff in those bottles really does seem to be just plain oil. Completely unreliable. Then I saw someone on XDA post a video of a fully transparent, fully laminated glass protector for the Sony XZP. And that’s when I noticed: the lamination process uses “optical adhesive” as the filler. It’s liquid going on, and sets into a semi-solid — way more trustworthy than oil. So I went looking for someone on eBay selling it, and what do you know, I found a seller offering liquid optical gel for white-edge repair. Tried it right away. Works well. Thicker than your average white-edge oil, but it still seeps into the edge just fine — a little pressure with your finger is enough.
