What should I do if my Redmi Note system is damaged?

For the problem of multi-threaded resource sharing, the synchronization mechanism adopts the method of "time for space", while threadlocal adopts the method of "space for time". The former provides only one variable for different threads to queue access, while the latter provides one variable for each thread, so it can be accessed at the same time without affecting each other. Spring solves thread safety problems with ThreadLocal We know that in general, only stateless beans can be shared in a multi-threaded environment, and in Spring, most beans can be declared as singleton scopes.

Summary. Hello.

There is a certain chance that this will happen, Xiaomi mobile phones are bought more, and the number of times is naturally more, is it possible that other brands of mobile phones must be intact if they fall? If you sell less, you will appear less often, and that's the reason.

Why does the Redmi note9 break when it falls, hello.

There is a certain chance that this will happen, Xiaomi mobile phones are bought more, and the number of times is naturally more, is it possible that other brands of Wu Hao mobile phones must be intact if they fall? Sold less, the number of appearances brother Zheng is also less, and the cavity dust line is like this.

Is there a more drop-resistant mobile phone?

It can even be explosion-proof and shock-proof.

Buying a good mobile phone case can solve this problem, otherwise you will have to buy Nokia's old man's machine. Due to the large screen of the current pure thinking mobile phone, it cannot be used to make eggplant balls to explosion-proof and shock-proof.

As a result, I fell, and the inner screen on the wooden floor broke.

Silicone shells are more resistant to rubbers than plastic shells, and soft shells are generally more resistant to drops than hard shells. Thicker silicone phone cases have better drop resistance. Special hall such as pie recommended airbag phone case, the internal particles have a cushioning effect, is the best anti-drop effect I have ever used to dress up the phone case, generally the four corners are thickened, around the camera heightened, better protect the phone from being broken and scratched.

Actually, I know this, but I deliberately don't test the phone itself against the shell.

Now only the button to take the mobile phone is the most drop-proof eggplant shed, the current mobile phone falls even if the screen is not broken, the circuit board is also prone to internal injury, so don't do such an experiment, my mobile phone fell a few times to accept the screen is fine, the battery is not durable.
