Be ready to replace it, it should be a broken screen from the picture.

If the screen is not broken, the cable is broken, which does not cost a lot of money.

Hello: According to your description, after the mobile phone is strongly **, it may be illuminated into the components of the virtual soldering, short circuit, partial damage to the screen or virtual connection of the cable base.

Hello:Hello:

From your situation, the display screen is faulty, and the display may need to be replaced, it is recommended that you send the mobile phone for repair to the local service center, and the engineer will test it for you, and the specific ** is subject to engineering testing.

1. Listen to your description, I don't think there is a virus, but the newly installed application needs to be initialized (some applications need to restart the phone to initialize), or the newly installed application has some conflict with the system (the blurred screen is the manifestation of the conflict), if it returns to normal after restarting, it will be no problem;

2. The possibility of the mobile phone being rooted when you don't know it is too low, basically the big brand mobile phone will not allow the application to be rooted without the user's permission. The easiest way to check if your phone is currently rooted is to test whether the system apps can be deleted, if so, then you are rooted (or use 360 assistant or Android optimizer to check);

ps:1、Install the application as much as possible from a safer market,In addition, pay attention to the installation of the application as far as possible to ensure that it is original and genuine,Do not install a copycat or pirated version (you can use the "whitewashing" function of the pea pod to detect).

2. If there is a conflict between the installed applications and the phone cannot be used normally, you can use the KIES on the computer to do an emergency recovery for the phone (this tutorial is official for Samsung, you can refer to it).

Finally, I want to say:I'm also using i9300,I don't feel that there's anything wrong with the camera that comes with the system.,Why do you want to update it?

This doesn't have to worry so much about anything, it's just that there are too many processes when you use the software, and it's just stuck. It's OK now it's okay If you don't brush root, you must not have root Now a lot of software can't guarantee that there are no bugs Don't worry about it, it won't be many times Once in a while, don't care.

No, it's a newly installed program, which causes instability in the system, and generally reboots in this case.

That permission, and then delete those junk software, it won't be stuck.

Tragedy, the stick is more fragile than the apple.

Take off the phone card and put it on and take a look.
