I always have a case, but no screen protector, the case extrudes enough from the front to protect the screen most of the time.
I used to have a screen protector, but because it adds extra width it went outside the edge of the case and it broke. And honestly I prefer microscratches over trapped dust particles. The only reason I’d put a screen protector on my phone now would be to replenish the oleophobic coating, and I’d do it, it’s just that idk which brand I could trust to actually have a good one included.
No case, no screen protector, only have a single micro scratch, had the phone a year and a half.
I use a cheap android phone (<$120 when I bought it 3 years ago). I protect it with cheap case + Hydrogel screen protector. I’m satisfied with Hydrogel type screen protector as it still on good condition even after my phone falls screenfirst many times. There are many scratches right now on the screen protector, but it still usable and not annoying as most scratches located on the edge of screen. Most of them caused by falling sceenfirst to gravel ground and asphalt several times… lol.
Yes, I own a case and glass screen protector. I went without a screen protector with an old Pixel and ended up with quite a few microscratches that drove me nuts. A friend of mine used a case but no screen protector on his iPhone and I don’t know how he does it. I’d be constantly worried about scratches.
