In general, the case materials for your iPhone have been  carefully selected by  Apple . So you don't need to worry too much whether it's metal or tempered glass, because they all have their pros and cons. But certainly glass material is still more beautiful and luxurious.

As for the best way to clean the iPhone case, according to Apple, you just need to gently wipe your phone with an antibacterial wet cloth or wipe with 90 degree alcohol, 70% isopropyl alcohol or cloth. Clorox sterilization is ok.

On some older iPhone models (iPhone 7 Plus and below) have you seen mysterious characters printed on the back of the device? Are they Apple messages or not?

1. Designed by Apple in California: Your iPhone is designed by Apple in California.
2. Assembled in China: Assembled in China.
3. Model A1 ***: Information to identify your iPhone model.

Next up will be the meanings of the icons below.

1. FC: Stamped by the US Federal Communications Commission. Allow this iPhone to be commercialized.
2. Trash marked trash: You should not throw your phone in the trash for environmental reasons.
3. Remaining icons: iPhone has passed EU censorship regulations.

And for those of you who are using a new iPhone with no more characters on the back, don't worry. Because since 2014, President Barack Obama has approved a new policy on electronic labels. Allows manufacturers to no longer have to let a bunch of censorship icons fill your smartphone, and instead add them to the device's software.

This will help the manufacturer to save their own costs and protect the environment. They will also make the phone look cleaner and more refined.

If you are using an iPhone 6 or 6S, turn the device over and see, do you see two subtle white lines? You know, those are not decorative details, even without them, your phone is worthless. Because of them, these are actually the phone's antennas, and with them your device can be used.

As for why the previous models did not have, but the iPhone 6 and 6S did not have, the reason is simply because people used aluminum alloy for the entire design of the case, when the antenna can not be hidden in the body is also possible because the aluminum alloy prevents radio waves from passing through, which means the antenna cannot receive and transmit signals. So, plastic window strips were created to solve this problem.
