My HUAWEI phone/tablet freezes or experiences lag

Freezing or lag after system update

System update-related freezing or lag occurs because the system optimizes apps after an update. In this case, the device's payload is high. Optimization lasts up to a week. To reduce the chance of freezing or lag following a system update, it is recommended, following an update, to charge the device with the screen off for at least 2 hours. Check whether freezing or lag disappears after one week.

Freezing or lag after Power saving mode is enabled

To disable Power saving mode, go to Settings > Battery > Power saving mode/Ultra power saving mode. Keeping the battery level above 20% is also recommended. If Power saving mode is on or the battery level is too low, the device will turn off features to prolong your battery life.

Freezing or lag when the device is charging or overheats

Your device features an overheating protection mechanism that prevents it from getting too hot by reducing system performance. To keep your device working normally, avoid using it while it is charging, and reduce the screen brightness and disable unnecessary and power-intensive apps, as well as features such as Bluetooth and NFC.

If your device heats up, turn off the screen to lower the temperature and check whether freezing or lag is relieved.

Freeze or lag when the memory is insufficient

If the available memory is less than 20% of the total memory, the performance of your phone/tablet might degrade.

  1. An easy way to close all running apps is to restart your device.
  2. Then, open Phone Manager/Tablet Manager, touch Cleanup, and follow the onscreen instructions to delete unnecessary files and/or uninstall rarely used apps. For optimal app performance, it is recommended that you keep at least 20% free storage space on your device.
  3. To uninstall a rarely used app, touch and hold the app icon, and select Uninstall.

Freezing or lag when there are too many files in the memory card or when the memory card does not function as normal

  1. Too many files may slow down the read and write speeds. It is recommended that you regularly clear the memory card to ensure at least 10% space is always free, or back up important data and format the memory card.
  2. A faulty memory card may also slow down read and write speeds. If a message is displayed indicating that the memory card is not functioning as normal, replace the memory card as soon as possible.
  3. For the best performance, it is recommended that you use internal storage as the default location for apps and files.

If the Default location option is not displayed after you insert a memory card into your phone/tablet, your phone/tablet does not support changing the default location.

Freezing or lag due to some third-party apps

  1. Uninstall any third-party management apps installed on your device, as they tend to conflict with Phone Manager/Tablet Manager provided by your device.
  2. If your device freezes when using a third-party app, contact the app or call Huawei hotline.

Other scenarios

  1. Update the system

    Make sure that the system and apps are all updated to their latest versions. New versions will optimize the device performance.

    To update the system, go to Settings > Software update > Check for updates, or go to Update in the My HUAWEI app.

  2. Restore to factory settings

    Back up your data, and restore your phone/tablet to its factory settings.

If the issue persists

Back up your data and take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance. We will do our best to address your needs.
