Settings and instructions to fix device lag issues
DEVICE LAG ISSUES:
What should you do if the customer complains that the device lags or the performance of the device is not smooth?
Please identify if there is a lag on the device when a certain application is being used or if it is observed even during normal use.
If lag is observed when a particular app is being used, follow the steps below:
1. Go to Settings
2. Tap on "Apps"
3. Select ‘Manage Apps’
4. Select the app that is causing the problem
5. Tap on "Clear data" button. This will clear all app data and it will now behave like a newly installed app.
6. Ask the customer to check for that application's latest update on Play Store. If the customer has installed an apk from somewhere else, ask him to download the latest version from the source & check. At times, .apk files are not fully compatible with the device
If the issue still persists, uninstall & re-install the application from the Play Store.
If the issue is observed during normal use circumstances, please follow the steps below:
1. Check for the version of MIUI the device is currently on. If on an older version, ask the customer to use the updater app and update to the latest version of MIUI. If this problem occurred after a recent system update & if it is a known issue, ask customer to wait for the next software release.
To check for updates, go to Settings > About Phone > MIUI Version logo > Check for Updates
2. Stop unnecessary background applications
Settings > Apps > Installed apps > choose the unnecessary app (there will be a green/blue broken line-circle or it will have 'Running' for app running in background) > Tap on Force Stop
3. Similarly, you can also delete cache data by opening Security > Select the Trash Can Icon (Cleaner) and clear all unwanted things
4. Turn off Auto Start for occasionally used apps
Security App >> Manage App>> Permission>>Auto Start >> Turn Off Auto Start
5. Inform customers that certain 3rd party apps like anti-malware/spyware apps are known to slow down the performance of a device due to multiple threads running in the background always. The customer can try uninstalling such apps & check if it helps. Also, when multiple such apps are installed, the system performance will be poor.
If the customer continues to face lag issues, ask the customer to backup all data and perform a "Factory Reset".
Please don't forget to ask the customer to transfer the backup file to a computer/removable storage device before doing a factory reset
