Vertical lines on a phone screen can often be fixed. In this case, I would recommend following a few troubleshooting steps to try and resolve the issue.
1. Update Android and Restart Device: The first step is to make sure your phone is running on the latest Android software version. Sometimes, software glitches or bugs can cause display issues. To update your Android, go to the Settings app, navigate to “System” or “About Phone,” and look for the “Software Update” option. Install any available updates and restart your device.
2. Remove Case and Battery/SIM Card: Sometimes, a faulty case or loose connections can cause display problems. Try removing the case from your phone and check if the lines disappear. Additionally, if your phone has a removable battery and SIM card, power off your device and carefully remove them. Wait for a few minutes before reinserting them and turning the phone back on.
3. Enable Safe Mode: Safe Mode allows you to start your phone with only the essential system apps running, which can help determine if a third-party app is causing the problem. To enable Safe Mode, press and hold the power button until the power options menu appears. Then, long-press the “Power off” option until you see a prompt to enter Safe Mode. Once in Safe Mode, check if the lines still appear. If not, it indicates that a third-party app may be causing the issue.
4. Check for Physical Damage: Inspect your phone screen for any physical damage such as cracks or scratches. If you find any, it’s possible that the lines are a result of the damage. In such cases, the screen may need to be repaired or replaced by a professional.
5. Factory Reset: If the problem persists even after trying the above steps, you can consider performing a factory reset. This will erase all data on your phone, so make sure to back up any important files before proceeding. To factory reset your Android device, go to the Settings app, navigate to “System” or “About Phone,” and look for the “Reset” or “Backup & Reset” option. Select “Factory data reset” and follow the on-screen instructions.
If none of these steps resolve the issue, it may be necessary to contact the manufacturer’s support or visit a professional technician for further assistance. Keep in mind that hardware-related problems might require repair or replacement, depending on the severity and warranty coverage.
Remember, these troubleshooting steps may vary slightly depending on your specific phone model and Android version.
