Most of us typically place our phones right side up when not in use. However, the best way to protect your phone during idle times is by turning it face down.
When you place your phone face down, you protect the rear camera from scratches caused by contact with the table. The front camera is protected by tempered glass, but the rear camera is not.
Furthermore, turning your phone face down can help safeguard your privacy and reduce the risk of your messages or personal information being exposed.

According to experts, these are the advantages of placing your phone face down on a table.
Prevent dust and liquids from coming into contact with the screen
Dust can stain your phone screen when you place it with the screen facing up. The screen and protective film may be scratched when cleaning.

In addition, if you place the screen upward if you accidentally spill water or food... they will hit the phone screen directly. To limit these undesirable factors, keep your phone face down when you place it on a table or when you are not using it.
Protect the camera from scratches
Most current phone models are designed with the rear camera cluster protruding from the back, so if you place the phone on its back, the camera cluster will come into contact with the surface below, potentially causing damage over time. It may cause scratches on the camera lens, affecting the photo-taking ability and photo quality.

If you are worried that turning your phone upside down will scratch the screen, you can proactively equip it with a screen protector to better protect your phone screen.
Better privacy protection
When you place your phone face up, incoming notifications will appear on the screen. This way, people around you can read your notifications. This affects your privacy because if unfortunately sensitive information arrives, your information will be exposed.

Therefore, you should place your phone face down when placing it on a table to prevent people around you from inadvertently reading the text messages you receive on your phone.
Improve concentration
Smartphones always have a notification feature on the phone screen to help users identify new messages. The notification feature can be said to be a strong point because it helps you receive messages faster, but the downside is that it can distract you from your work when messages keep arriving and there are too many.

To overcome the above drawbacks, you can place your phone face down on a table or turn off notifications on the lock screen.
This way, you can stay focused because no notifications are disturbing you, but you can still read them as normal when you unlock the screen without worrying about losing them.
