This article helps troubleshoot the touchscreen not responding on your LG K3
You may have touchscreen issues if your phone:
These steps help identify and resolve the underlying cause. After completing each step, test to see if the issue is fixed. If not, continue to the next step.
Verify if your screen protector or protective case is interfering with the touchscreen.
Sometimes, the thickness or texture of a screen protector or the pressure of a protective case affects the touchscreen's performance.
Try removing any screen protector or case, and test to see if your issue is fixed.
Caution: Some screen protectors may not reapply properly.
Note: Use only LG K3-compatible protective cases.
Perform a soft reset.
A soft reset deletes any temporary files that may be causing the issue, but does not erase any of your content or data.
Identify if the operating system is affecting touchscreen functionality.
If these steps don't solve your issue, a broader performance issue may be the cause.
Note: To optimize device performance, be sure your LG K3 is running the most recent device software. Check for software updates.
