What to do if the Nubia z7 MAX mini has a poor signal

hi！Hello、、

I'm happy to answer questions for you, and there are many reasons why the signal is not good.

If you are wearing a metal phone case, then we recommend changing the leather case or plastic. If you feel that the signal is not ideal after flashing, we recommend that you re-upgrade the system under the double clearing, pay attention to the upgrade pro needs to be backed up by the data, click to view the upgrade tutorial and the system rom** link.

I hope the reply is helpful to you, if you don't know anything, welcome to enter the official website of Nubia.

hi！Hello, first of all, please confirm whether the local signal itself is good and stable, and it is recommended to change other mobile phones and SIM cards to compare and test. Secondly, please check that the correct carrier and network mode are selected in Settings - Mobile Network Settings.

Try switching to airplane mode or restarting. No, please back up your data, restart Shuangqing, or upgrade to the latest version of the system.

If none of the above can be improved, please send it to the after-sales test.

Kiss. I'm using the z7max signal, which is very good. Is it a regional problem and an operator problem?

Generally speaking, the signal is not good, and it is recommended not to wear a phone case. The phone case will affect the signal, the plastic does not affect... There are also pros who can try to upgrade to the latest version.

The new version is optimized for a lot of problems.。。。

hi！Hello, do you mean to make a squeaky sound, and in what circumstances does it come out, in everyday applications or on calls? In this case, it is recommended to back up the data and double clear the system or re-flash the official latest ROM to try. No, please send it to the after-sales service.

Double clearing method (pay attention to the backup data, the system data will be cleared after double clearing):

1. Use the volume up and down keys to move the cursor, move the cursor to the wipe data factory reset line, and then press the power button to select;

2. Use the up and down keys of the volume to move the cursor, move the positive and closed keys to the yes--delete all user data line, and press the Huiyuan button to select it;

3. At this time, the phone will perform a factory reset operation, and then the phone will return to the main menu;

4. Also use the up and down keys of the volume to move the cursor, move the light hall clear answer mark to the wipe cache partition line, and then press the power button to select;
