At onoff.gr, we don't just do “polishing” - we follow a specific, professional process developed through years of experience and thousands of repairs. The most important part? We don't need to remove the screen! The entire process is performed with the device as-is, preserving its authenticity and safety.
The first and most critical step is protecting your device. We apply a special UV-curable waterproof adhesive around all openings, buttons, and sensitive areas.
We carefully seal the microphones, speakers, charging port, volume/lock buttons, and even the microscopic gaps between the screen and frame. Every detail matters!
We place the device in a professional UV lamp for 3-5 minutes. The ultraviolet radiation “solidifies” the adhesive, creating a rigid, waterproof barrier.
Our UV lamp is specifically designed for smartphone repairs - it's not the kind used in nail salons! It has exactly the right wavelength and intensity to cure the adhesive without damaging the OLED/AMOLED screen.
Now comes the main part! We place the device (with the fully protected screen) in a special mold that holds it steady and secure.
We use a professional polishing machine with rotating pads of varying roughness. It's not a regular “polishing machine” - it's specifically designed for smartphone screens with:
Using a coarse paste (3000-5000 grit) to remove the deepest scratches. This is where we “level” the surface.
Medium roughness paste (7000-9000 grit) for smoothing and removing traces from the first stage.
Very fine paste (12000+ grit) for mirror-like finish and final shine. The screen regains its glossy appearance.
Total polishing time: 2-6 hours depending on the depth and extent of the scratches.
The final step is equally important! We apply a special “sealing oil” (oleophobic coating) that:
It's the same coating that all new screens come with from the factory! Through regular use, it gradually wears off - we restore it after polishing, bringing the screen back to its factory condition.
We place the device back in the UV lamp for 2-3 minutes for the oleophobic coating to dry and stabilize. Meanwhile, we carefully remove the protective adhesive from step 1.
A screen that looks almost brand new! The scratches have disappeared (or been dramatically reduced), the shine has been restored, and the touch feels smooth and natural. All of this without ever removing the screen from the device!
As you can see, the difference is impressive! From a scratched-up screen to one that looks almost brand new. And the best part? You kept your original screen - we didn't replace anything!
Important: If we're not 100% satisfied with the result, we repeat the process or recommend replacement (with a discount for the attempt).
