Recently I read some blogs regarding protection of smartphones. Some blogs have mentioned smartphone covers and some have talked about cases. If we go through Apple's official site, it shows only iPhone cases and NOT iPhone covers. Here, the main title is 'iPhone covers' and they have written 'case' everywhere that makes me confused.
To my mind, covers are used to cover the entire smartphone, but have a little or no role in its protection, while cases can protect smartphones even if they don't cover them.
My questions are:
1. My assumption regarding cover and case is right or wrong?
2. At times, people write cover for case and vice versa, so are they interchangeable words?
3. Flip cover or back cover can be said Flip case or back case?
4. Is it ok to say the smartphone cover a skin or a sleeve? Does it cover only the screen or the entire smartphone?
