Ever since Apple released an iPhone with curved edges (the iPhone 6) a lot of people have had problems finding the right screen protector, one of the main reasons is the problems that come with the curved edges of the screen:
- Standard glass screen protectors do not cover the curved edges
- Glass screen protectors that try to cover more of the screen suffer from air bubbles or "halos" due to air creeping in from the small spaces caused by the curved iPhone screen
- Edge to edge screen protectors have been known to have "halos" or air bubbles
- Plastic screen protectors can cover the whole screen but are not that protective
- Self-healing screen protectors made form a thicker plastic sometimes have problems sticking to the phone screen
- Anti-glare and privacy screen protectors have the same issues outlined above (if you choose the standard glass or standard plastic versions)
