Common faults
Other faults
What's the screen doing?
Select all that apply โ helps confirm what type of replacement is needed.
Black screen, flicker or backlight issues can be caused by a connector fault or logic board issue rather than the screen itself. Dan will confirm before ordering parts.
๐ก iPhone 12+ โ third-party screens show "Unknown Part" in Settings. Genuine OEM screens remove this warning and restore True Tone.
What's the battery doing?
Select all that apply. Most common signs: dying at 20%+ or draining noticeably faster.
Excessive heat can indicate a swollen or failing battery. Dan will inspect before replacement.
What's the damage?
Select all that apply โ helps Dan assess the repair method.
A bent or damaged frame may affect the repair approach and water resistance. Dan will assess on arrival.
A screen or back lifting away from the frame is a strong sign of a swollen battery. Do not charge the device.
Back glass cracks can allow glass shards to contact the battery. Does the phone feel warm, swollen, or has the back bowed outward?
A warm, swollen or bowed battery may have been pierced by glass. Dan will inspect on arrival. Do not charge the device.
What's the camera doing?
Select all that apply โ we'll work out whether it's the lens, the module, or both.
Camera function issues
Physical / visual damage
Camera crashes and black screen can sometimes be fixed with a software reset โ Dan will check before replacing anything.
Dust between the glass and sensor usually means the camera module needs replacing โ the lens glass alone won't fix it.
If the camera otherwise works fine and it's just the glass that's cracked, a lens glass replacement (ยฃ50) may be all that's needed.
A cracked lens left too long often lets dust and debris into the module, damaging the camera itself. Dan will confirm on arrival โ we'll quote both as a bundle.
๐ง Tell us about the water damage
Select all that apply โ helps Dan prepare the right assessment.
Switch the device off immediately if it's on. Don't charge it. The sooner Dan can assess and clean the board, the better the chances of recovery. Send as quickly as possible.
What's happening with Face ID?
Select all that apply โ helps Dan understand what's going on.
On iPhone 11 and older, Face ID is paired to the logic board at the factory and cannot be restored โ even Apple cannot fix it. Dan will confirm on arrival.
If it stopped working after a screen repair, the TrueDepth sensor may have been disturbed โ there's a small chance it can be resolved.
iPhone 12 and newer can have Face ID restored using Apple's Self Service Repair programme with professional tools. The part needs to be ordered specifically for your device โ Dan will confirm the repair is possible before ordering.
โฑ Allow an extra 1โ3 working days for parts to arrive. Dan will keep you updated throughout.
What's happening with the device?
Select all that apply โ Dan will use this to prepare the right diagnostic.
If "iPhone is disabled", Dan can attempt a restore. You'll lose data unless you have a backup.
Won't turn on and boot loops can be caused by hardware (battery, logic board). The ยฃ40 diagnostic covers both.
ยฃ40 diagnostic โ comes off the repair cost if Dan fixes it.
What's not working?
Select all that apply โ speaker, mic, buttons and small components are all the same price.
Speaker and mic issues are sometimes caused by software or a blocked grille. Try restarting and cleaning the grille gently first.
Small parts priced the same as a charging port repair.
What's happening with charging?
Select all that apply โ helps Dan confirm it's the port and not the cable or battery.
A port that won't seat the cable is often blocked with pocket lint. Try a wooden toothpick to clear debris gently โ fixes it for free in many cases.
Port replacement fixes physical port damage โ price varies by model.
Tell us about the lens damage
Select all that apply โ helps Dan figure out if it's just the glass or if the module underneath needs replacing too.
Physical damage to the glass
Is the camera itself still working?
Camera works fine, it's just the glass cover. Quick job โ no data loss. If the crack is new, this is the right fix.
Blur, spots, vibration and noise usually mean the module underneath has been damaged โ often from a cracked lens left too long. Dan will confirm on arrival. We'll quote both as a bundle.
Dan can still help โ send your details below and he'll quote directly. Usually within 30 minutes.
