Samsung is offering free screen replacements for specific Galaxy smartphone models in India due to a widespread issue where users have reported green lines on their screens. The program, which runs until April 30, applies to Galaxy S20, Note20, S21 (excluding S21 FE), and S22 series devices that are less than three years old and not physically or water damaged. Samsung has established that the issue is caused by faulty software updates affecting Super AMOLED displays on these models. Customers can visit a Samsung Service Center before April 30 to book an appointment and have their faulty screen replaced with a new one that also includes a new battery for enhanced performance.
