And then have a shattered back or screen. People need to take their phone out of their case once and week and wipe it down.
I use cases but take it out of the case once a week and wipe it down with a micro fiber cloth.
I do have a way of not having a broken screen or back. I don’t drop my phone. I know that seems like a strange concept, but it has worked well for me over the last 10 years of owning iPhones.
