Solution:
1. After upgrading, charge the phone for more than 2 hours (preferably overnight), and then restart the phone to ensure that the installed applications in the phone have been optimized.
2. If the phone has been stuck, you can use the following methods:
(1) Clean up storage space and running memory.
When the mobile phone runs out of memory and storage space, the application will get stuck. I suggest you go to the mobile phone housekeeper to clean it up:
A. Enter the phone manager and click Optimize/Optimize Now. After optimization, the phone manager will display the optimization results and setting suggestions. According to the prompts, complete the corresponding settings.
B. Enter the mobile phone housekeeper and click Clean to accelerate. After scanning, click Clean immediately after cleaning, delete redundant files according to the prompts, uninstall uncommon applications, and keep enough storage space (it is recommended to reserve more than 20%).
(2) Restart the phone
Please restart your phone and try again. Restarting can end the running application and alleviate the stuck phenomenon.
(3) Check whether the mobile phone is hot or used when charging.
The unique overheat protection function of mobile phone will reduce the system performance appropriately. It is suggested that you try to avoid using your mobile phone while charging, reduce the screen brightness appropriately, and turn off applications and functions that are not used or consume abnormal power, such as Bluetooth and NFC.
(4) Check the memory card
A. There may be too many files stored in the memory card (it is recommended to reserve more than 10% space), which leads to slow reading and writing speed. It is recommended that you clear the memory card space, or back up important data (third-party applications such as QQ and WeChat need to be backed up separately) before formatting the memory card.
B. It may be that the memory card hardware is abnormal. Have you ever been prompted that "the memory card is abnormal"? If so, I suggest you replace the memory card as soon as possible.
C. If the default storage location of the mobile phone is a memory card, it is recommended that you change the default storage location to "Internal Storage" and try again.
(5) Turn off the power saving mode and keep sufficient power.
If the power saving mode has been turned on, it is recommended to turn it off (setting >; Battery > power saving mode and super power saving), and keep sufficient power (above 20%). In power saving mode and low battery state, the mobile phone will reduce its performance to save power.
(6) uninstall the third-party mobile phone housekeeper software
If your mobile phone is equipped with third-party mobile phone management software, please uninstall such applications 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.
(7) Check whether the mobile phone is downloading, copying and transmitting.
If your mobile phone feels stuck when uploading and downloading (files, pictures, videos, applications, etc.). ), copy (file management copy data, etc. ), and transmission (mobile phone cloning, Huawei sharing, etc. ), I suggest you wait for the task to end or stop this operation.
Tip: You can drop down the status bar to check the progress of uploading, downloading and transferring files.
(8) Upgrade the system version
A. If the phone is already Root, please revert to the official stable version. For details, please call Huawei Customer Service.
B. It is recommended that you update your mobile phone system in time and upgrade your application to the latest version. The new version will optimize system performance. Update method: Go to mobile phone settings, search for software updates, and click Check for updates.
Tip: Restoring the version and upgrading the system version will cause data loss. Please back up the data in advance (QQ, WeChat and other third-party applications need to be backed up separately).
(9) Restore factory settings
Please back up important data (QQ, WeChat and other third-party applications need to be backed up separately), restore the phone to factory settings and try again.
If the problem still exists, please back up the data (QQ, WeChat and other third-party applications need to be backed up separately) and bring the purchase voucher to Huawei customer service center for testing and processing.
Warm reminder: You can choose to charge at night (or close the screen for more than 40min), which can sort out the memory fragments of the mobile phone to some extent and alleviate the phenomenon of card sticking.
