Huawei Mate 20 Pro Repair

The Huawei Mate 20 Pro was one of the most technically ambitious phones of its generation. It had a curved OLED display, an in-display fingerprint sensor, proper 3D face unlock, and it was the first phone that could wirelessly charge other devices from its own battery. All of that ambition has consequences when something breaks, and it is worth understanding before you commit to a £179 screen replacement.

How much does a Huawei Mate 20 Pro repair cost?

Our fixed prices at iExpert Repairs are:

• Screen replacement – £179
• Battery replacement – £65
• Charging port repair – £59
• Diagnostic service – £15

Each includes the part, the labour and a 12 month guarantee, with no assessment fee added afterwards. The £15 diagnostic applies only to faults outside this list and includes a fixed quote before any work begins.

The green tint problem, and what it actually is

If the edges of your Mate 20 Pro display have taken on a green cast, particularly at low brightness or on dark backgrounds, you are not imagining it and you did not cause it. A proportion of these handsets developed exactly that fault, and it became well known enough that Huawei addressed it publicly at the time.

It is a panel-level problem rather than a software one, so no update or setting change will remove it. A screen replacement resolves it. Before you book anything, though, it is worth establishing whether your handset falls under any remaining Huawei support for the issue – we would rather point you there than take £179 for something you might not need to pay for.

Both an in-display fingerprint sensor and 3D face unlock

The Mate 20 Pro is unusual in carrying two proper biometric systems. The fingerprint reader sits behind the display, and the notch houses a genuine 3D depth-sensing array for face unlock rather than the simple camera recognition most Android phones use.

Both have implications for a screen repair. The new panel has to be seated correctly against the fingerprint sensor and enrolment tested afterwards, or you end up with a flawless screen and a reader that recognises nothing. The face unlock module in the notch has to be transferred and re-seated precisely, and a fraction out leaves you with unlock that works intermittently or not at all. We test both before any Mate 20 Pro goes back. If you are comparing quotes elsewhere, ask whether they do.

Curved OLED, and why the screen costs what it does

The panel curves over both long edges, which means the glass is bonded around the sides of the frame rather than sitting flat on top of it. Removing one requires controlled heat to release the adhesive, and fitting the replacement requires re-bonding it evenly. Rush either step and the panel lifts at an edge within weeks.

The curve also makes the phone less forgiving of a drop onto its side. A Mate 20 Pro that lands on an edge frequently damages the display even where the glass looks undamaged – shifted colours, a coloured line, or dead touch areas all point to the panel rather than the glass.

Reverse wireless charging and the battery

This was the first phone that could charge other devices wirelessly from its own battery, and owners who use that feature notice the cell ageing sooner, because it is doing more work. At £65 a replacement is straightforward, and the cell is bonded in with adhesive that must be eased out slowly rather than levered.

Confirm the battery is genuinely the problem first. A worn cell handles messaging and browsing perfectly well and then drops sharply during camera use, navigation or video calls. Sudden collapse under load is the signature. If the phone feels slow rather than short of charge, check available storage before assuming the battery.

Charging faults: free checks before you pay

Change the USB-C cable – after this many years most original cables have failed internally at the strain relief. Then change the mains plug. Then look into the socket with a torch for compacted pocket lint, which we clear at no charge. Only when all three come back clean is our £59 charging port repair the right answer.

Wireless charging after a screen or battery repair

The Mate 20 Pro charges wirelessly and can also charge other devices from its own battery, and both of those depend on a coil sitting directly behind the rear glass. It is worth knowing because a repair that involves opening the phone has to put that coil back exactly where it was.

If wireless charging has become unreliable – working only in one particular position on a pad, or not at all – after a previous repair elsewhere, that is usually a coil that has been reseated slightly out of position or a connector that was not fully clipped back down. It is not a software fault and no update will fix it. We check wireless charging works before returning any Mate 20 Pro, because it is precisely the sort of thing an owner discovers a week later rather than in the shop.

What we check before your Mate 20 Pro goes back

A screen replacement on this model is not finished when the display lights up. We test touch response into all four corners, fingerprint enrolment through the display, face unlock, the earpiece and loudspeaker, all three rear cameras, the proximity sensor and the ambient light sensor.

The proximity sensor is the one rushed repairs miss most. Fitted slightly out of position it fails to blank the screen when you lift the phone to your ear, so your cheek mutes people mid-call. It looks like a software bug and it is not.

How long does a Huawei Mate 20 Pro repair take?

Battery and charging work is usually completed the same day once the phone is with us. Screen replacement takes longer, because a curved bonded OLED has to be heated out and re-bonded cleanly and both biometric systems need testing afterwards. We confirm timing alongside the fixed quote and start only once you approve it.
