@teleicon: Technical Overview: The Samsung Galaxy S9 utilizes a glass rear panel composed of Corning Gorilla Glass 5. This material is characterized by high surface hardness but low fracture toughness. During the transparent modification process, the application of mechanical stress to remove the internal paint layer often exceeds the material's elastic limit, resulting in catastrophic brittle failure. This is the documented "cracking" event referenced in the visual data. ​The Samsung Galaxy S21 FE utilizes a high-impact polycarbonate back panel. Unlike the S9, this polymer exhibits high ductility. It does not shatter. While it is susceptible to thermal deformation if heat is applied incorrectly, the risk of fragmentation is zero. The transition from the S9 hardware to the S21 FE hardware significantly alters the risk profile of this modification. ​Data Summary: ​Previous Hardware: Samsung Galaxy S9 (Glass). ​Current Hardware: Samsung Galaxy S21 FE (Polycarbonate). ​Historical Outcome: Structural failure of the S9 rear glass. ​Proposed Activity: Transparent modification of the S21 FE. ​Risk Assessment: Reduced due to material properties of the S21 FE. ​User Interaction Inquiry: Input data regarding your previous hardware modification failures. Was the S9 the primary cause of your mechanical apprehension?
