The Samsung Galaxy S20 Ultra launched in February 2020 as Samsung's camera-flagship halo device, headlined by a 108MP main sensor and a 6.9-inch 120Hz Dynamic AMOLED 2X display that was, at the time, among the largest and smoothest screens on any phone. Six years on, that same screen is now the part most likely to end a Galaxy S20 Ultra's working life — a cracked panel, a dead touch digitiser, or persistent green/pink tinting after a drop are the most common reasons owners search for a replacement.
This guide covers what a genuine screen replacement costs in the UK in 2026, how it compares with other repair routes, a step-by-step DIY replacement process, and — because this is now a 5-6 year old flagship — an honest answer to the question every owner eventually asks: is it still worth repairing?

Display Specifications
- 6.9-inch Dynamic AMOLED 2X panel
- 3200 x 1440 pixel resolution (Quad HD+)
- 120Hz adaptive refresh rate (at FHD+ resolution)
- In-display ultrasonic fingerprint sensor
- HDR10+ certified
- Corning Gorilla Glass 6 front protection (glass on original panels)
- Snapdragon 865 (US/China markets) or Exynos 990 (UK, EU and most other regions) chipset — the display and digitiser are the same across both variants
- Model reference: SM-G988B (UK/EU), SM-G988U (US)
Because the S20 Ultra's fingerprint sensor is built into the display itself, a poor-quality replacement panel can affect unlock reliability as well as touch accuracy — worth keeping in mind when comparing parts, not just prices.
Samsung Galaxy S20 Ultra Screen Replacement: Cost Comparison
| Repair Option | Price (UK) | Pros | Cons |
|---|---|---|---|
| DIY replacement (The Repair Plus part) | £74.78 (part only) | Lowest total cost; keep the device same-day; no waiting on postage both ways | Requires confidence with a heat gun/plastic tools; self-installed, so any mistakes are on you |
| Independent repair shop | Typically £170-£200 (estimate) | Professional fitting; often same-day; usually comes with a warranty | 2-3x the cost of a DIY part; quality varies by shop; still uses third-party parts, just marked up |
| Samsung official repair | Check current pricing via Samsung UK's official repair cost checker | Genuine Samsung parts; official warranty; won't affect any remaining manufacturer warranty | Highest cost by a wide margin; postal turnaround if no Samsung Experience Store nearby; a 6-year-old device may face parts availability questions |
| Trade-in / replace the phone | Varies (trade-in value minus new device cost) | Newer hardware, updated software support, current battery health | By far the most expensive route; loses a phone that may otherwise still be perfectly serviceable |

Is It Still Worth Repairing a Samsung Galaxy S20 Ultra in 2026?
This is a fair question for any phone approaching six years old, and it deserves a straight answer rather than a sales pitch.
The honest case against repairing: the S20 Ultra no longer represents the cutting edge, and depending on your Android version and Samsung's support cycle for this model, you may be behind on the latest security updates. If the battery is also degraded, or you've had other component failures, sinking money into an ageing device has diminishing returns.
The honest case for repairing: a 6.9-inch 120Hz AMOLED display, a 108MP camera system, and IP68 water resistance are still genuinely capable specs for everyday use — texting, browsing, calls, photos, streaming. If the screen is the only thing wrong with an otherwise functioning phone, replacing it is a fundamentally different decision to replacing a phone with a failing battery, a broken camera, and a cracked screen all at once.
Where the maths gets genuinely favourable is the price point. At £74.78 for the part, a DIY repair costs a fraction of what most independent shops charge just for labour on a newer flagship, and nowhere near what a replacement phone would cost. Compare the £74.78 part price against a typical independent shop quote of £170-£200 (estimate) for the same repair, or the cost of a new mid-range phone, and the repair math clearly favours fixing what you have — provided the rest of the phone is healthy. If you're only replacing a cracked screen on a phone that otherwise works well, £74.78 is a low-risk way to get another year or two out of it.
The exception: if the battery is also degraded (visible swelling, poor battery life, or the phone struggling to hold charge), factor in a battery replacement at the same time — doing both while the phone is already open is far more efficient than opening it twice.
How to Replace a Samsung Galaxy S20 Ultra Screen: Step-by-Step
This is a moderately advanced repair due to the curved edges and the in-display fingerprint sensor cable. If you haven't opened a phone before, budget extra time and work slowly.
- Power off the phone completely and remove any case or screen protector.
- Apply heat around the edges of the display using a heat gun or heat pad on a low setting to soften the adhesive holding the screen to the frame.
- Insert a suction cup near the bottom edge of the screen (avoid the curved sides) and gently lift while sliding a thin opening pick or plastic spudger along the seam to separate the adhesive.
- Work around the entire perimeter slowly, reapplying heat as needed, being especially careful around the top and bottom edges where the display cables sit.
- Once the screen is loosened, lift it carefully — do not pull it fully away yet, as the display and fingerprint sensor ribbon cables are still connected underneath.
- Disconnect the display connector and fingerprint sensor cable using a plastic spudger, then remove the old screen completely.
- Transfer any small components that remain attached to the frame (earpiece speaker cover, brackets) if your replacement part doesn't include them — check what's included with your specific part before starting.
- Connect the fingerprint sensor cable and display connector on the new "For Samsung Galaxy S20 Ultra OLED LCD with Frame" screen assembly, checking both are fully seated.
- Power the phone on before sealing it to test the display, touch response, and fingerprint sensor — this is the point to catch any connection issues.
- Apply new adhesive strips around the frame edge, following the original adhesive channel.
- Seal the screen into place, pressing firmly around the perimeter, then use a case or clamps while the adhesive cures.
Because this part comes as a complete OLED display with frame, you're not transferring the frame from the old screen, which reduces the number of extremely fiddly steps (frame separation is one of the hardest parts of this repair when done as a standalone LCD-only replacement).

Frequently Asked Questions
How much does a Samsung Galaxy S20 Ultra screen replacement cost in the UK?
A DIY replacement part costs £74.78 from The Repair Plus. Independent repair shops typically charge £170-£200 (estimate) including fitting, while Samsung's official repair pricing is higher still — check Samsung UK's repair cost checker for a current quote.
Will replacing the screen affect the fingerprint sensor?
The Galaxy S20 Ultra uses an in-display ultrasonic fingerprint sensor built into the screen assembly, so it comes with the replacement panel. It's important to connect the fingerprint sensor ribbon cable correctly and test it before fully sealing the phone, as a poor connection is the most common cause of fingerprint issues after a screen swap.
Does the replacement screen support the full 120Hz refresh rate?
The Repair Plus's "For Samsung Galaxy S20 Ultra OLED LCD with Frame" is designed to match original specifications, including 120Hz support. As with the original display, 120Hz operates at FHD+ resolution rather than the full Quad HD+ resolution, which is standard behaviour for this model, not a limitation of the replacement part.
Is it worth repairing a 6-year-old phone like the S20 Ultra?
If the screen is the only fault and the rest of the phone — battery, cameras, charging — is working well, yes: at £74.78 the repair cost is low relative to a replacement phone, and the S20 Ultra's 120Hz AMOLED display and 108MP camera are still capable specs for daily use. If multiple components have failed, weigh the cumulative repair cost against buying a newer device.
Can I replace the screen myself without professional tools?
You'll need at minimum a heat gun or heat pad, a suction cup, plastic opening picks or a spudger, and replacement adhesive strips. These are inexpensive and widely available, but the curved-edge design of the S20 Ultra makes this a moderate-difficulty repair — go slowly and don't force the frame apart.
What's included with the replacement screen?
The Repair Plus part is a complete OLED display with frame assembly, meaning you receive the full screen unit pre-fitted into a frame, rather than a bare LCD/OLED panel you'd need to transfer into your existing frame.
How long does a Samsung Galaxy S20 Ultra screen replacement take?
A DIY replacement typically takes 45-90 minutes for a first-timer, most of which is spent carefully removing the old adhesive. Independent shops often offer same-day turnaround.
