Cracked your screen? Do these 4 things first
12 July 2026 · NZ Phone Screen Repair team
A cracked screen is annoying, but the first hour matters more than most people realise. Glass dust, moisture and pressure on a damaged digitiser are what turn a cosmetic crack into a black screen, ghost touches or a failed front camera. Here is exactly what to do before you hand your phone to a technician anywhere in New Zealand.
1. Back up your phone straight away
A screen repair should never touch your data, but a damaged display can stop responding to touch at any moment — and if you cannot unlock the phone, you cannot authorise a backup later. Do it while the screen still works.
On an iPhone, open Settings, tap your name, then iCloud, then iCloud Backup and choose Back Up Now while on Wi-Fi. On Android, open Settings, then Google, then Backup, and tap Back up now. If your data cap is tight, plugging into a laptop and copying photos across works just as well.
- Confirm the backup actually finished — check the date and time stamp, not just that you tapped the button.
- Make sure you know your passcode and Apple ID or Google password. A good shop will never ask for them, but you will need them to re-verify after the repair.
- Photograph the damage before you drop it off, so there is no debate about the phone's condition on hand-over.
2. Tape the crack and stop it spreading
Cracked glass keeps moving. Every time the phone flexes in your pocket, the fracture travels a little further, and once it reaches the edge of the display the OLED panel underneath is far more likely to fail. That is the difference between a straightforward glass-and-digitiser job and a full display assembly replacement.
A strip of clear packing tape or a cheap screen protector over the top holds the fragments in place, keeps glass out of your fingers, and stops dust working its way into the panel. It is a five-minute fix that can genuinely save you money.
- Use clear tape, not duct tape — adhesive residue makes the technician's job slower.
- Do not press hard on the cracked area to test the touch layer.
- Keep the phone out of your back pocket until it is repaired.
3. Check for hidden damage beyond the glass
Before you get quotes, work out what else the drop broke. A shop can only quote accurately if it knows whether the fault is glass, panel, touch layer, or something deeper. Two minutes of testing at home means fewer surprises at the counter.
Open the camera app and check both lenses for blur or spots. Make a call and listen through the earpiece and speaker. Run a finger across the whole screen in Notes to find dead zones. Check that Face ID or the fingerprint reader still authenticates, and look for green or pink lines, flickering, or patches of black — all signs the panel itself is going.
- Discolouration, lines or a spreading dark blotch means the display assembly needs replacing, not just the glass.
- Ghost touches — the phone typing or opening apps by itself — point to a damaged digitiser.
- If the phone got wet as well as cracked, say so. Water damage changes the diagnostic path entirely.
4. Get two or three quotes before you commit
Screen prices in New Zealand vary widely between shops in the same suburb, and the cheapest quote is not automatically the best value. What matters is the part grade, the warranty length, and whether the shop can do the job while you wait.
Use the directory to shortlist shops in your city, then ask each one the same three questions: what part are you fitting, how long is the warranty, and how long will the repair take. Any shop that will not answer clearly is not the shop for you.
- Ask whether the quote includes GST — some shops advertise the pre-GST figure.
- Confirm the warranty covers touch and brightness faults, not just physical failure.
- If your phone is under two years old and you have insurance or AppleCare, check that first — it may be cheaper than a paid repair.
