Quelle / Source: https://zcratch.com/en/remove-display-scratches --- ## Remove display scratches on smartphones and tablets No screen replacement, no repair appointment: Zcratch UV fills scratches in display glass optically. All you need is the kit, a matching protector and about 15 minutes. ## Does it fit your device? - All smartphones and tablets with a flat or slightly curved glass display - You need a tempered glass or thick plastic protector for your model - Works even with several scratches at once - Apple Watch models have their own kit with a different dosage ## Tempered glass or plastic film — which is better? #### Tempered glass (recommended for phones & tablets) Tempered glass is rigid and lies perfectly flat, so the Zcratch UV spreads evenly and no bubbles remain visible. For smartphones and tablets it is the best choice. #### Thick plastic film Works as well and is often the only option on strongly curved edges. Sufficient material thickness is essential. #### Thin screen film — not recommended With thin films the adhesive shows as a bubble. The result looks uneven even though the scratch itself is filled. ## The process in short ### APPLICATION ON SMARTPHONE & TABLET 1. Apply polish to the scratches and polish briefly 2. Clean the display thoroughly from grease, dust and polish residue 3. Apply Zcratch UV to the center of the display 4. Place the protector from the side and lower it slowly 5. Push air bubbles outwards without pressure 6. Cure under UV light 7. Peel off excess material and clean with isopropanol ## What the result costs you - Screen replacement at a repair shop: a three-digit amount plus waiting time - Zcratch UV kit: bought once, usable several times - No data loss, no shipping your device, no opened hardware If your display still works and only looks bad, replacing it is almost always the more expensive route. - [Zcratch UV kit for smartphone & tablet](https://zcratch.com/en/products/zcratch-kit-for-smartphones-tablets) - [Matching screen protectors](https://zcratch.com/en/products/zcratch-compatible-protective-films) ## Frequently asked questions about display scratches ### Does it work on every smartphone?
