1: restart the phone.

Please restart your phone and try again. It is recommended that you restart your mobile phone every 2~3 days, which can effectively clean up the cache and alleviate the card jam phenomenon.

2: Check whether the mobile phone is hot or used when charging.

When the mobile phone has a serious fever, its performance drops and it gets stuck. It is recommended 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.

3: 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.

4: Clean up the storage space.

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:

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.

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.

5. 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.

6. Reasons for system deadlock after system upgrade: After system upgrade, the application in the mobile phone will be optimized at the beginning. At this time, the mobile phone has a high load and may be stuck when used. It is recommended to charge the mobile phone for more than 2 hours after upgrading, and then restart the mobile phone to ensure the optimization of the installed applications in the mobile phone.

7: Restore factory settings.

Please back up important data, and back up third-party applications such as QQ and WeChat, and then restore the phone to factory settings and try again.

8: Still unable to solve.

If the problem still exists, please back up the data (QQ, WeChat and other third-party applications separately) and go to the official customer service center for testing and processing.
