Shut down and try again, in addition, it may be that your mobile phone software version is old, it is best to update it.

You can go directly to customer service to flash the machine, which can generally be solved

I'm using 550, don't be so troublesome if you simply upgrade, just update it directly through your phone, steps: 1. Mobile phone settings....Update the service....Search for updates, if the original phone is used normally, but there is a recent problem, you can restore the factory settings by yourself first, the operation is as follows: phone settings....From the new settings....All reset, and finally go to the after-sales service if it doesn't work.

The phone also has a CPU, memory.

You can also run programs, viruses are also a kind of degree, and of course mobile phones can also be infected with viruses.

It will also crash. Possible cause 1

Maybe it's because you haven't flashed your phone for a long time, and the software is out of order, causing your phone to freeze.

2. You drive too many things.

You didn't take your time.

It's like a computer that will get stuck and freeze if it's turned on too much.

The principle is the same.

3 may be poisoned.

4. Cable hardware issues.

Crash workaround.

1. You just go and flash the computer (equivalent to the system reinstallation of the computer).

It is recommended to flash the machine) 2 soft grid machines.

If you won't flash your phone.

Go to Symbian to register and then find the forum of your corresponding model to find the post of flashing the machine.

There are a lot of them in it, so if you can't do it, send them to the store to repair them.

4. If the above methods do not work, go to the mobile phone store or brand service department to check the hardware.

Please save the information before flashing the machine.

so as not to be inconvenienced. Personal summary.

I don't know how to ask questions. Thank you.
