About this repair

The Galaxy S21 runs a flat 6.2-inch Dynamic AMOLED 2X with the Qualcomm 3D Sonic ultrasonic fingerprint sensor bonded under the glass, so we recalibrate that reader after every panel swap. Its 4000mAh cell sits beneath a glued plastic Glasstic back that we heat-release and re-seal to preserve the S21's IP68 gasket. The G991 routes charging through a separate USB-C daughterboard, letting us renew a worn port without disturbing the mainboard, and we flash-check for the model's known green-line AMOLED fault before return.

Will my fingerprint scanner still work after a Galaxy S21 screen replacement?

Yes — the S21's ultrasonic 3D Sonic reader sits under the AMOLED and comes with the screen assembly, so we recalibrate and re-enroll prints to keep under-display unlock working as before.

Why is there a green vertical line down my Galaxy S21 screen?

That green line is a known Dynamic AMOLED 2X failure on the S21 where the display ribbon degrades; software won't clear it, so the G991 needs a fresh OLED-with-frame assembly.

Can you fix my S21's USB-C port without replacing the whole board?

Yes — the S21 carries its charging port on a separate USB-C daughterboard, so we swap just that flex-mounted part to restore charging while leaving your data and mainboard untouched.
