Last time, the new column of the machine brother "cold knowledge", it seems that you still like it.
Let's take another issue while it's hot today and get up.
A while ago, when the eighth brother was watching the mobile phone reviews of other media, he found a strange problem: the same iPhone SE, why I have in my hand, and what I have in other people's hands, looks different

See the difference?
The machine in the hands of the brother has a "clean" back, except for an apple logo, nothing. Someone else's machine also hit three laser etched marks on the back:
If you often look at the overseas media mobile phone reviews, you will find that this is actually a very common difference, obviously the model of the mobile phone is exactly the same, but the back cover looks different.
Not only Apple, but also the domestic manufacturers they got the same mobile phone, such as this:

The original good back cover was engraved with a bunch of seals.
No matter how noisy your back cover is, you can't run:

Why? Brother Ji will talk about this today.
The above several mobile phones with stamps on them are from the Netherlands, Italy, Poland and other EU countries.
According to EU regulations, electronic equipment sold in the EU Economic Area needs to clearly indicate the certification and regulatory markings on the body of the device.
The most important of these is the CE (European Qualification Certification) mark on the left of the figure above, indicating that it has been certified and can be legally sold.
As an electronic device, the mobile phone also needs to be marked with the WEEE (Waste Electronic Electrical Equipment Directive) label on the right, which meets the EU standards for the recycling and regeneration of waste electronic equipment.
"Labeling" as an EU mandatory regulation inevitably makes the machine you love ugly.
Apple, after the iPhone 12, tried to make the label less eye-catching, typing them on the side border of the phone:
Elsewhere, though, there are less uncomfortable restrictions.
In most other countries and regions outside the European Union, these signs can be electronically hidden in the "Settings" app of the mobile phone without explicit display.
The back cover of the phone is much cleaner.
