Why it matters
Original parts vs cheap copies
Every part in this phone is its own original part. Nothing has been swapped for a cheap copy. Here’s why that matters.
Original partCheap copy part
Screen
True colours, full brightness and True Tone, with smooth, precise touch
Duller colours, lower brightness and often no True Tone. Touch can lag or miss
Battery
Full rated capacity, safety-tested, and Battery Health reads correctly
Often less real capacity, can run hot or swell, and Battery Health may show “Unknown” or “Service”
Cameras
Sharp focus, accurate colour, and Night mode and stabilisation work as designed
Softer photos, slow focus, and some camera features can stop working
Face ID & Touch ID
Works securely, exactly as the manufacturer intended
Can stop working completely, and copy parts can’t bring it back
Messages on your phone
No “Unknown Part” or “Non-genuine” warnings in Settings
iPhone can show an “Unknown Part” message that stays in Settings
Water & dust seals
Precise original fit and seals
Looser fit and weaker seals, so more likely to fail early
Resale value
Keeps its full trade-in and resale value
Worth less when you sell or trade it in, and some shops refuse it
Every Fone4U phone is tested in Ireland and covered by our warranty. If a part ever needs replacing, we only fit a genuine one.
