If your Samsung Galaxy S23 Ultra has a cracked screen, dead pixels, or a display that won't respond to touch, you're not alone. The S23 Ultra's large 6.8-inch curved-edge display is one of the most impressive screens on any phone — but that size and the S Pen digitiser built into it also make it more exposed to drops and more expensive to fix than a standard smartphone screen.
This guide walks UK Galaxy S23 Ultra owners through every screen repair option available in 2026: official Samsung repair, independent repair shops, and DIY replacement using a genuine-fit part. We'll cover real UK pricing comparisons, a step-by-step DIY replacement process, and answers to the most common questions people search before booking a repair.

Samsung Galaxy S23 Ultra Display Specifications
- Screen size: 6.8-inch Dynamic AMOLED 2X
- Refresh rate: 120Hz adaptive (scales down to save battery when high refresh isn't needed)
- Chipset: Snapdragon 8 Gen 2 for Galaxy — used globally for the S23 Ultra, not restricted to the US market
- Release date: February 2023
- S Pen: Built-in, stored in the chassis, with a digitiser layer integrated into the display — this is why S23 Ultra screens can't be swapped for a generic Galaxy S23 panel
- Curved edges: The display curves gently at the left and right edges, which affects how the frame and screen are bonded together
Because the S Pen digitiser, touch layer, and OLED panel are fused into a single assembly on the S23 Ultra, a genuine-fit replacement needs to include all of these components — this is why S23 Ultra screens are sold as a complete "OLED LCD with frame" unit rather than a bare panel.
Samsung Galaxy S23 Ultra Screen Repair Cost Comparison (UK)
| Repair Option | Price (UK) | Pros | Cons |
|---|---|---|---|
| Samsung official repair (in-store/mail-in) | Typically £200–£300+ (estimate — check Samsung's UK support site for a current quote) | Genuine Samsung parts, manufacturer warranty on the repair, no risk to remaining device warranty | Highest cost, longer turnaround if mail-in, may require full device backup/reset |
| Independent repair shop | Typically £120–£180 (estimate — varies by shop and part quality used) | Faster than manufacturer routes, often same-day, competitive pricing | Part quality varies by supplier, may void any remaining Samsung warranty, quality depends on technician skill |
| DIY replacement | £92.28 (part only) + your time | Lowest total cost, full control over part quality and timing, no labour charge | Requires confidence with small screws/adhesive/ribbon cables, voids remaining warranty, risk of accidental damage if rushed |

How to Replace a Samsung Galaxy S23 Ultra Screen (DIY Guide)
This is a moderately advanced repair due to the curved-edge display and S Pen digitiser. If you haven't done a smartphone screen swap before, take your time, work on a clean, well-lit surface, and keep screws organised by the step they came from.
What you'll need
- A genuine-fit "For Samsung Galaxy S23 Ultra OLED LCD with Frame" replacement screen
- Precision screwdriver set (Phillips #000 and Torx as needed)
- Plastic opening/prying tools and a spudger
- Suction cup or screen-opening pliers
- Heat gun or hairdryer (to soften adhesive)
- Tweezers
- New adhesive strips/pre-cut adhesive for reassembly
- Anti-static mat or wrist strap (recommended)
Step-by-step replacement
- Power off the device completely and remove the SIM tray.
- Apply gentle heat around the edges of the screen using a heat gun or hairdryer on a low setting to soften the factory adhesive.
- Create an opening point with a suction cup near the bottom edge and carefully insert a plastic opening tool into the gap.
- Work the opening tool around the perimeter slowly, reheating sections as the adhesive resists, being especially careful around the curved edges where the glass is more fragile.
- Lift the screen assembly from one side like a book, but do not remove it fully yet — the display and battery connectors are still attached via ribbon cables underneath.
- Disconnect the display ribbon cable(s) and any S Pen digitiser connectors using a plastic spudger, then set the old screen aside.
- Remove any transferable components if your replacement is a bare panel (this specific part is sold with the frame included, which simplifies this step considerably).
- Connect the new screen assembly, reattaching the display ribbon cable(s) and digitiser connector in the same order they were removed.
- Test before sealing — power the device on and check touch response across the full screen, S Pen function, and refresh rate behaviour before applying new adhesive.
- Apply new adhesive strips around the frame and press the screen firmly into place, working from one edge across to the other to avoid trapping air bubbles.
- Reinsert the SIM tray and leave the device under light pressure (or in a case) for a few hours while the adhesive fully bonds.
If at any point the ribbon cables feel like they're not seating correctly, stop and re-check alignment rather than forcing the connection — these connectors are delicate and not designed to be repeatedly forced.

Frequently Asked Questions
How much does it cost to replace a Samsung Galaxy S23 Ultra screen in the UK?
Costs vary widely by repair route. Samsung's official repair service is typically the most expensive (often £200–£300+, estimate), independent repair shops tend to sit somewhere in the middle (typically £120–£180, estimate), and a DIY replacement using a part like our OLED LCD with Frame (£92.28) is the lowest-cost option if you're comfortable doing the work yourself. Always confirm current pricing directly with Samsung or your chosen repair shop, as prices change.
Can I replace just the glass, or do I need the full screen assembly?
For the S23 Ultra, glass-only repairs are technically possible in some specialist shops but are rarely recommended. Because the S Pen digitiser and touch layer are bonded directly beneath the outer glass, glass-only separation carries a high risk of damaging the OLED panel underneath. Replacing the full OLED LCD with Frame assembly is the more reliable approach and is what our listed part provides.
Will replacing the screen affect my S Pen functionality?
Not if you use a genuine-fit assembly that includes the digitiser layer, as ours does. The S Pen relies on an EMR (electromagnetic resonance) digitiser built into the display stack, so using a proper full-assembly replacement — rather than attempting to reuse a damaged digitiser — is important for keeping S Pen input accurate.
Does replacing the screen myself void my warranty?
Yes, in most cases. Opening the device yourself or having a non-Samsung-authorised shop perform the repair will generally void any remaining manufacturer warranty on the device, and may also affect eligibility for Samsung Care+ style coverage if you have it. If your phone is still within warranty and undamaged by anything other than the screen fault itself, it's worth checking with Samsung first.
How long does a DIY screen replacement take?
For someone doing their first S23 Ultra screen swap, budget 45–90 minutes, including time for the adhesive to soften and for careful reassembly. Experienced technicians typically complete it faster, but rushing the adhesive removal step on your first attempt is the most common cause of cracked replacement glass or bent frames.
What's the difference between an OLED and an LCD replacement screen?
The Galaxy S23 Ultra uses Samsung's Dynamic AMOLED 2X (OLED) technology from the factory. The product listed here — "OLED LCD with Frame" — refers to the industry naming convention used across the parts trade, but functionally it's an OLED-based replacement matching the original panel type, not a downgrade to LCD technology.
Is it worth repairing an S23 Ultra in 2026, or should I upgrade?
The Galaxy S23 Ultra remains a capable flagship with a Snapdragon 8 Gen 2 chipset, 120Hz display, and built-in S Pen — specs that hold up well against many current mid-range and even some flagship devices. If the rest of the phone is in good working order, a screen replacement at £92.28 (part cost) is significantly more cost-effective than replacing the device, particularly if you're comfortable with DIY repair or have access to a trusted independent shop.
