How to solve Huawei's card change?

Cell phone jam may have the following reasons:

When using WeChat, Caton:

When the number of WeChat contact items exceeds 1000 or there are too many contact conversations, there may be a phenomenon that the operation is unresponsive. Suggestion:

(1) Enter WeChat >; I > Settings > General > WeChat Storage Space > Manage WeChat Storage Space, select chat records, videos and pictures that are no longer needed, and click Delete.

(2)EMUI5。 X: enter the mobile phone housekeeper >; Cleaning acceleration > space management > wechat is committed to cleaning up unnecessary pictures, videos and files.

EMUI8。 X/9.0: Enter the mobile phone housekeeper >; Clean up and accelerate > optimize the space occupied by WeChat, and delete unnecessary pictures, videos and files.

Magic UI 2.0: enter the mobile phone housekeeper > clean up and accelerate > optimize the space occupied by WeChat, and delete unnecessary pictures, videos and files.

(3) If it still cannot be solved, please try the following general solutions to system congestion:

Please keep the battery of the mobile phone higher than 20%: when the battery of the mobile phone is low, in order to extend the standby time and protect the mobile phone, the performance of the mobile phone will be limited.

Uninstall third-party mobile phone housekeeper software: If your mobile phone has third-party mobile phone management software installed, please uninstall this kind of application and try again. Usually, this kind of software conflicts with the mobile phone housekeeper that comes with the mobile phone, which will lead to the running jam.

Use the official stable version system: If the mobile phone is already Root, please revert to the official stable version.

Clean up background applications in time: too many applications running in the background may cause the system to get stuck. I suggest you clean up the background process in time.

Change the phone settings through the phone manager:

Click "phone manager > boot management" to close the software that does not need to be started automatically when booting.

Click "phone manager > cleaning acceleration" to clean the cache.

Pause some background downloads or file copies: background downloads or file copies will occupy system resources, so it is recommended to avoid multiple downloads at the same time.

It is recommended to clean the memory of the mobile phone regularly to avoid the phone from being stuck due to insufficient remaining memory space.

If the device supports microSD card storage, please unplug, replace or clean the SD card: when your microSD card stores too many files, or the quality of the microSD card used is poor and the reading and writing speed is slow, the system will get stuck when reading files. If the phone is not stuck after pulling out the microSD card, it is recommended that you replace the genuine high-speed microSD card, and try to avoid excessive storage of the microSD card in daily use.

Use data network or WLAN with stable network speed and signal: When the network is unstable, it will lead to high delay of online games and slow loading when playing online videos and online music.

Upgrade the application to the latest version: In daily use, it is recommended to upgrade the application to the latest version in time. The latest version will optimize some known problems and improve the experience.

Upgrade the system to the latest version: It is recommended that you back up your own data |(QQ and WeChat need to be backed up separately), and upgrade to the latest version of your mobile phone through online upgrade or Hisuite.

Clean up notifications and reminders regularly: It is recommended that you clean up notifications and reminders regularly, and click the trash can icon in the drop-down status bar.

If the application frequently pushes notifications, it is recommended to turn off its push notification function:

EMUI8。 X and below: Click Settings > Applications and Notifications > Notification Management > Select the application that needs to turn off notification > Turn off notification permission;

EMUI9。 X: Click Settings > Notification Center to select the notification to be closed and apply the notification to be closed;

Magic UI 2.0: Click Settings > Notification Center > Select the application that needs to turn off notification > Turn off notification permission.

Restart the mobile phone: If the mobile phone is not turned off for a long time, it will lead to too much data cached in the system and the mobile phone will not run well. You can try to restart the phone to recover.

When playing games, Caton:

1. I suggest you pay attention to the running software and hardware requirements of this game. If the mobile phone does not meet the requirements of large-scale games for running software and hardware, the game may get stuck.

2. I suggest you reduce the game frame rate and high-definition display appropriately to reduce power consumption and fever.

3. It is suggested that you close the background application that you don't need to use temporarily, or restart your phone and try again.

4. Please upgrade the game application and system version to the latest version, and then try again.

5. It is recommended that you turn off the power-saving mode (Settings > Battery > Power-saving Mode/Super Power-saving) and keep sufficient power (above 20%).

6. It is recommended that you keep sufficient storage space of your mobile phone, not less than 10%.

7. It is suggested that you add the corresponding game in the game assistant/application assistant to start the game acceleration.

8. It may be that your memory card stores too many files and the reading and writing speed is slow, which causes the system to get stuck when reading files.

9. When receiving SMS and MMS, the data service will be interrupted, and the game may be stuck or dropped.

10. I suggest you contact the game customer service for feedback, which may be the compatibility problem of the game.

When the phone is connected to WIFI, it will be stuck:

1. We suggest you switch to another network, or turn on airplane mode for 5 seconds, then turn it off and try to connect again.

2. It is suggested that you temporarily turn off Bluetooth and reconnect the WLAN, or connect the 5GHz WLAN.

3. It is recommended that you wait for the automatic synchronization application under WLAN to complete synchronization, and then try again. If automatic update under WLAN is set, it will occupy the network to synchronize data.
