Precautions: Backing Up Your Data

Before delving into potential fixes, safeguarding your phone's data is imperative. As these lines might indicate irreversible damage, the solutions attempted could result in data loss. Ensuring a backup of essential files and apps on your device is crucial. Methods such as automatically backing up your phone, using Google One, or transferring data to another device can secure your valuable information. If uncertain about the backup process, seeking assistance from a professional repair center is advisable.

Solutions to Resolve Horizontal or Vertical Lines on Android Devices:

Method 1: Restart Your Phone

A simple yet effective solution for minor glitches causing these lines is a straightforward restart. Pressing the volume button for a few seconds initiates a reboot menu; proceed by tapping on the "Restart" option and allow your phone to complete the process.

Method 2: Cycling the Battery

For instances where white lines persist, cycling your phone's battery might prove effective. Allowing the battery to charge to 100% and then drain to 0% can often eliminate these lines upon subsequent full charging.

 Method 3: Utilize Safe Mode

If prior methods haven't yielded results, accessing safe mode can help determine if the lines stem from a faulty app or software. Enter safe mode by holding the Power button as if turning off the phone, then tap and hold the Power Off icon for a second or two. Choose 'Reboot to Safe Mode' when prompted, and check if the lines disappear. If they do, uninstall recently downloaded apps until the issue resolves. If the lines persist, hardware failure is likely, prompting a visit to a repair center.

Method 4: Factory Reset Your Phone

A comprehensive approach often considered the ultimate fix is the "Factory Reset." This process reverts your phone to its factory settings, erasing all downloaded apps and files. Access this feature through Settings >> System >> Backup and Reset, and follow the on-screen prompts. Remember, a factory reset wipes all data, so ensure a backup beforehand.

Seeking Professional Assistance

If the lines persist despite attempting the aforementioned methods, it's prudent to consult a reliable mobile repair store. Persistent lines often indicate a faulty hardware component requiring repair or replacement. Opting for an authorized service center ensures quality repair at reasonable costs, with genuine components meeting your specific requirements.

This detailed guide covers a range of troubleshooting steps and precautions for addressing the pesky issue of vertical and horizontal lines on phone screens, offering users multiple avenues to resolve the problem.
