Nubia Z7mini phone has no mute after reset, what is going on with functions such as flipping?

hi！Hello, if the phone has been rooted, root may lead to system instability, it is recommended to cancel root, and back up the data after the system is double-cleared after the card swiping the official system.

If the phone is not rooted, please check whether the phone settings can be set, mute and other functions, it may be that the system is restored to default after the phone is restarted, if not, it is recommended to restart again or restore the backup data to factory settings.

Hello for your situation, it is recommended that you.

1. Restore factory settings again.

2. Upgrade to the latest version.

3) Press the power button and the "volume up button" at the same time, and release the power button to enter recovery mode after powering on.

4) Select "Wipe Data Factory Reset" and then "Yes --Delete All User Data".

5) Go back to the main interface, select [Wipe Cache Partition] and then select [yes --Wipe Cache].

6) Go back to the main interface, select [Install Zip from SDCARD] and then [Choose Zip from SDCARD], then select the ROM package you put into the memory card

7) Select Yes --Install.

8) Wait for the flashing to complete, then go back to the parent menu and select [Reboot System Now] - [No].

The first flashing reboot is relatively long, please wait patiently, it will not take more than 10 minutes.

Nubiaz9mini can achieve a mute effect by doing the following:

1. Press and hold the volume down button to mute the phone;

2. Pull down the notification bar and turn on the silent mode switch;

3. Turn on the phone mute switch in the phone settings - sound.

If the above situation is ruled out and the phone automatically jumps to silent mode, it may be caused by abnormal compatibility between the software, you can carefully check whether the mute switch is turned on, etc., or the third-party mobile phone management tool installed has modified the phone, or the extreme power saving mode is enabled in Nubia Electrician (as shown in the figure).

If the local check is invalid, you can try to restore the phone to factory settings and upgrade to the latest version of Nubiaz9mini, the upgrade package can be found in the Nubia official website forum--Product area--Z9mini--Official ROM release.

Well,,, is it the system? I'm not here to answer questions.,I just want to grab a white mini for my family.,But the response on the Internet doesn't seem to be very good.,When I see someone asking questions, I'll ask him questions.,Don't mind.。

Is there anything else in the mini used by the landlord in addition to the above problems you said? Like a stuttering phenomenon? Is the charging heating very powerful?
