Common iPhone 12 questions

An iPhone 12 screen replacement starts at a budget LCD from £99 (3-month warranty — a good temporary or data-transfer option), a quality aftermarket OLED from £119 with the full 12-month warranty, a genuine Apple panel from £149, calibrated after fitting with no Settings warning. Prices vary across the An iPhone 12 family — the quote tool gives the exact figure for your model, and every price includes parts, labour, testing and return postage. Genuine Apple screens and batteries are calibrated after fitting on the iPhone 12 family, so Settings shows no warning; quality aftermarket parts show an “Unknown Part” note that doesn’t affect performance.
