Seeing a
black line on your mobile screen can be frustrating and often signals an underlying issue with your device. This problem usually stems from either hardware damage—such as a drop or pressure on the screen—or software glitches that disrupt normal display functions.
In some cases, a simple restart can resolve the issue if it’s software-related. Make sure your phone’s operating system is up to date, as updates often fix display bugs. If the black line on mobile screen continues to appear, consider performing a factory reset after backing up your data. This can eliminate any lingering software problems.
However, if the line remains after troubleshooting, it may be a sign of physical screen damage, such as a faulty LCD or loose internal connections. In that case, it's best to consult a professional technician for diagnosis and repair. Ignoring the issue can lead to further screen failure.
