Can Meizu mobile phone boot into the system? It is ok to know the data clearly, but if you want to keep the address book and other information, you can ask someone for advice.

What system are you using now? Is it flyme's?

The information and pictures in it will not be deleted, but the contacts, short messages, phone records and notebooks will be deleted.

Is your contact on the card or the mobile phone?

I suggest you go to the forum to register your account, then bind your mobile phone and open the cloud backup, so don't worry about it next time.

Did you turn on the synchronization function before? Bind the forum account.

You press the power button for about 10 seconds, and then start it normally.

Your mobile phone model.

If you hold it down for about 10 second, it will vibrate and turn it off.

Then you try to open it.

Well, try not to clear the data.

Are you a cell phone model?

I suggest you try to clear the data. Not yet. It is estimated that you will return to the factory.

Please call Meizu's customer service number first.

I haven't encountered this phenomenon yet.

Generally, press and hold the power button 10 second to turn it off.

Turn it on again, and it will be fine.
