Why can't my Meizu phone receive push messages and floating windows?

Because the system settings are wrong or the startup file has been deleted.

Can restore the factory settings to solve, the specific operation is as follows:

1. When the phone is turned off or restarted, press and hold the volume plus button for a long time and then press and hold the power button. When Meizu logo appears, release it at the same time, and the phone will enter the upgrade interface (recovery mode).

2. After this interface appears, connecting the computer through USB data cable will recognize the appearance of the removable storage disk marked Recovery.

3. Put the firmware in the root directory of the disk.

Note: There is no need to modify the file name and suffix of the firmware.

4. Disconnect, check the system update, and click "Start" in the lower right corner of the screen. After the firmware file is verified, it will automatically enter the brushing process.

Tips 1: In the recovery interface, you can move up and down with the volume button and confirm with the power button.
