1. The response is slow in a short time after the upgrade.

After the upgrade, the mobile phone will optimize the system application, and the response may be slow in a short time. Please observe the test after 1 day.

2. When using applications that need networking, the response speed is very slow.

If the WiFi network speed is slow or the cell phone signal is poor and the network speed is slow, it will lead to the slow response of the cell phone. Please change the WiFi hotspot, change the location of the mobile phone to ensure a good signal, or change the SIM card to ensure the stability of the network.

3. Try to restart the phone.

Restarting the phone can effectively clean up the cache and alleviate the jam phenomenon. It is recommended to restart the phone every 2-7 days.

4, clean up the phone memory

The free space of mobile phone running memory is too small, and the free space of mobile phone storage memory is too small (it is recommended to reserve more than 20% space), which will lead to slow response of mobile phone. Please slide up through the bottom and pause to enter the background in time to clean up the unused background programs. Please wait 30 seconds before operation. Enter I Manager, click "one-click optimization" to optimize the mobile phone, and if necessary, release more space through "space cleaning" to ensure that the available memory of the mobile phone is sufficient.

5, check whether the phone is hot.

The mobile phone has built-in intelligent temperature control function and high temperature protection function. When the temperature is high, the processor frequency will be reduced appropriately to reduce power consumption and heat generation. Please go to I Manager-Utilities-Phone Cooling-One-button Cooling to cool down your phone.

6. Check the power saving mode and power supply.

If the power saving mode is turned on, the phone will reduce the processor frequency appropriately to extend the battery life. I suggest you set the-battery, switch to the balance mode, and keep sufficient power (above 20%).

7. Uninstall the third-party mobile phone management software

The third-party mobile phone management software may have a functional conflict with the "I housekeeper" that comes with the mobile phone, resulting in a slow response. Please uninstall it and try again.

8. Adjust the game configuration

The higher the game resolution, special effects, anti-aliasing and other display effects, the heavier the processor load, which is more likely to lead to unstable game operation. It is suggested that the image quality of the game should be properly adjusted without affecting the visual experience.

9. Check accessibility.

If the barrier-free function is turned on, the load will increase and the performance will decrease. It is recommended to enter Settings-Quick Assist-Accessibility, and turn off unnecessary functions in time.

10, upgrade the system.

The new version of the system improves the compatibility and stability. It is recommended to go to Settings-System Upgrade-Upgrade the system to the latest version.

1 1, reset the phone.

Please back up your phone data, go to Settings-System Management-Backup Reset, click "Restore All Settings" to try, and if necessary, select "Clear All Data" to reset your phone and try again.
