The Samsung Galaxy S21 screen repair process

• Step 1 – Check-in & diagnosis: We inspect your Samsung Galaxy S21, confirm the screen fault and look for any additional damage, such as frame bends or back glass cracks.
• Step 2 – Safe disassembly: The handset is carefully opened using specialist tools and heat to protect the rear glass and internal components.
• Step 3 – Screen replacement: We remove the damaged display and install a high-quality OEM Samsung S21 screen, ensuring the frame and seals are correctly aligned.
• Step 4 – Reassembly & sealing: Your device is reassembled with fresh adhesive and seals to help maintain structural integrity and reduce dust ingress.
• Step 5 – Testing: We thoroughly test touch response, display brightness, colour, front camera, speakers and sensors before returning the phone to you.
• Step 6 – Ready for collection or postage: Once the repair passes all checks, we will notify you for collection or dispatch via our secure mail-in service.

Signs you need a Samsung Galaxy S21 screen repair

• The screen is visibly cracked, even if it still works.
• The display has coloured lines, flickering or discoloured patches.
• Touch input is not accurate or stops working in certain areas.
• The screen stays black, but the phone vibrates or rings.
• You can see black “ink” marks or bright white spots on the display.

If you notice any of these symptoms, it is best to repair your Galaxy S21 screen promptly to avoid further damage.
