Problems with Samsung phones! Please answer the expert!

Generally, mobile phones are replaced within a month if there is a quality problem. If it comes to the New Year, the time may pass. The odds of changing will be smaller.

It is possible for you to take it for repair. As for the information in the phone, it should not be saved. This has something to do with the specific problem with your phone.

If you're close to Xi'an, it's better to change it now. Save the trouble of the New Year.

When I wanted to buy U608, he told me that U608 had just come out and the quality was unstable, and he told me that it was best not to buy U608. You said that you just bought U608,It's not more than 3000,You must have been hacked,I was looking at the U608 licensed goods were more than 3,000 (probably**I forgot),Just a week later,That**It became about 2,008,At that time, I didn't dare to buy it.,Later, I bought a D908i.。

3. If you can operate the phone after restarting or charging, uninstall the third-party plug-in program that was operated before the black screen.

4. Back up your phone data (**book, short message, multi** file, etc.), and restore factory settings.
