2. Important Notes Before Installation

• Model Verification: Ensure your device is a Samsung Galaxy A52 5G (models SM-A526B, SM-A526U, SM-A526O, SM-A526W, SM-A5261). This screen is not compatible with Samsung Galaxy A53 5G.
• Screen Type: This is an INCELL TFT LCD screen. It is important to note that the INCELL screen size may be slightly smaller than the original AMOLED screen, and it does not support fingerprint sensor functionality.

• Component Transfer: This replacement screen does not include the volume buttons or the fingerprint sensor. You will need to carefully transfer the ribbon cables and small parts from your original screen assembly to the new screen.
• Pre-Installation Testing: Before fully installing the screen, connect the new screen's flex cables to the motherboard and test all functions (display, touch, etc.) to ensure it is working correctly. Do not remove protective films or adhesive until testing is complete and successful.
