Samsung i9000 changed the card after a few days, and occasionally the signal was interrupted and the screen was black. I went away for two days, and when I came back, I found that I could only send messages, but I couldn't answer them. In the gallery Then I ask what you have done to your mobile phone in the past two days, installing a lot of software and deleting some system files. Brush machine? Did you brush the radio? Or is the phone flooded or violently dropped?

Suggest the landlord, first erase the data, then use ROM integrated software, try to see if the problem still exists? If it's still the same, brush a CM ROM to see if the situation has improved. If you can't solve the problems of no signal, black screen and so on. Basically it can be judged that it is a hardware problem.

If it is a hardware problem, there are many situations that will lead to a black screen with no signal, such as virtual soldering of CPU.
