Edit- I guess I should have clarified, this survey is for people who didn't put a screen protector on their phone. I thought it was obvious, but maybe not.

I've seen some people say the coating lasts a year or two on average, but wanted to collect some more data points.
If you experienced the oleophobic coating wearing off any iPhone screen, please share:
1. iPhone model(s)
2. How much decrease in effectiveness (description or estimate percentage) after how much time
3. Light/moderate/heavy usage
4. Rare/moderate/frequent cleaning screen
5. Material(s) used for cleaning (hand, shirt/pants, microfiber, water, alcohol, combination, etc)
6. Any other relevant details
The data might be useful to draw new conclusions or reinforce old ones, or might not, we'll see. Thanks
