How To Fix The LG K30 Screen Flickering Issue
Before you do any of the recommended troubleshooting steps for this particular issue it’s best to make sure that your phone is running on the latest software version first. If an update is available then I suggest that you download and install it first. Once you have the latest software version installed then proceed with the troubleshooting steps listed below.
Perform a soft reset
The first thing you will need to do in this case is to refresh the phone software which can be done by a soft reset. Although this is usually done on an unresponsive device it should also work in this case. To do this step just press and hold the Power button and Volume Down until the device powers off, approximately 8 seconds, then release. Your phone should restart. Once this is done check if the screen still flickers.
Start the phone in Safe Mode
Sometimes an app you downloaded from the Google Play Store will cause the LG K30 screen flickering issue when it is installed. This happens if the app in question still has bugs or has compatibility issues with your device. To check if an app you downloaded is causing the problem you will have to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.
- With the screen on, press and hold the Power key.
- In the options menu that displays, tap Power off and restart.
- The device will restart and the Safe mode overlay will no longer show on the screen.
In case the issue does not occur in this mode then it is most likely caused by an app you installed. Find out what app this is and uninstall it.
To find out what app is causing the problem you will need to start the phone normally then uninstall an app. Once the app has been uninstalled check if the screen still flickers. Repeat this until the screen no longer flickers. The last app you uninstalled is most likely the culprit.
Wipe the cache partition of the phone
Sometimes the cached data stored in the dedicated partition of the phone can become corrupted. When this happens this will usually cause certain issues to occur on the phone. To eliminate the possibility that this is what’s causing the problem you will have to wipe the cache partition of the phone from the recovery mode.
- From the Home screen, tap Settings.
- Tap the ‘General’ tab.
- Tap Storage > Internal storage.
- Wait for menu options to finish calculating.
- Tap Free up space.
- Tap Temporary files & raw files.
- Select the following options: Cached data, Clip tray temporary files, Raw files from camera.
- Tap Delete > DELETE
Check if the issue still occurs.
Perform a factory reset
In case the above steps fails to fix the LG K30 screen flickering issue then your last option is to do a factory reset. Make sure to backup your phone data before doing the reset as this will be deleted in the process.
- Turn off the device.
- Press and hold the Power and Volume down buttons.
- When the LG logo appears, quickly release and then re-hold the Power button while continuing to hold the Volume down button.
- When the ‘Delete all user data (including LG and carrier apps) and reset all settings’ message appears, use the Volume down button to highlight Yes.
- Press the Power button to reset the device.
Once the reset is complete setup your phone again, but don’t install any apps yet, then check if the screen still flickers. If it does then this is most likely caused by a faulty hardware component in which case you will need to bring the phone to a service center and have it checked.
