However, it’s always best to follow the instructions carefully and make sure you’re using the official diagnostic codes provided by Samsung. Avoid using any third-party apps for screen testing, as they may not be reliable or could potentially harm your device’s functionality. Always ensure that you are operating within safe practices to maintain your device’s health.
