I use a good case (not the one the phone came with, Xiaomi cases are terrible) and a good tempered glass (the phone came with a low quality hydrogel). The phone is in great condition because i never drop it (phones are expensive in my country so i plan to use it for a lot of years)

Screen protectors are kinda expensive and break very often. I calculated it’s cheaper to replace my screen (which feels a lot nicer than a scren protector) whenever it breaks.

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.
