iPhone 12 Screen Replacement Guide UK — Cost, DIY Steps & Best Parts (2026)

iPhone 12 Screen Replacement Cost UK: £29.99–£51.72

A genuine-fit replacement screen for the iPhone 12 Mini costs £29.99, and for the iPhone 12 Pro Max it's £51.72, when bought as a standalone part from Supreme Phone Parts. Both are single-variant listings — one product, one price, no confusing option menus. The Mini uses an Incell LCD panel; the Pro Max uses a Soft OLED panel, which is the main reason for the price gap. If you're paying a repairer to fit it rather than doing it yourself, expect to add labour on top — but the part itself is the number that determines your baseline cost, and that's what this guide covers.

Below, we'll break down exactly why the two models are priced differently, what "Incell LCD" and "Soft OLED" actually mean for your money, and where the wider iPhone 12 generation — including the base iPhone 12 and iPhone 12 Pro — currently stands on availability.

Why Does iPhone 12 Screen Replacement Cost Vary So Much?

The short answer: display technology, not brand markup. Apple built the iPhone 12 range with two distinct panel types depending on model tier, and replacement part pricing tracks that split almost exactly.

• iPhone 12 Mini — Incell LCD. LCD panels are cheaper to manufacture because they use a simpler backlight-and-liquid-crystal layer structure rather than individually lit OLED sub-pixels. This is reflected directly in the £29.99 price point.
• iPhone 12 Pro Max — Soft OLED. OLED panels are self-emissive (each pixel produces its own light), which gives deeper blacks and better contrast but costs significantly more to produce and source as a replacement part — hence £51.72.

Screen size plays a secondary role too. The Pro Max's 6.7-inch display is the largest in the iPhone 12 family, versus the Mini's 5.4-inch panel, and larger OLED substrates carry higher per-unit costs across the supply chain.

iPhone 12 Screen Prices Compared

Model	Panel Type	Screen Size	Price	Product Link
iPhone 12 Mini	Incell LCD	5.4"	£29.99	Buy iPhone 12 Mini screen
iPhone 12 Pro Max	Soft OLED	6.7"	£51.72	Buy iPhone 12 Pro Max screen

Both listings are the only screen tier we stock for each respective model — there's no "budget vs premium" decision to make within a single device, which simplifies ordering considerably compared to ranges where three or four quality tiers exist per model.

What's Included at Each Price Point?

Every screen we sell, regardless of price, ships to the same baseline standard:

• 100% tested before dispatch — each unit is checked for touch response, display uniformity, and True Tone/Face ID compatibility before it leaves our warehouse.
• 12-month warranty — covers manufacturing defects, giving you a full year of cover on the part.
• Same-day UK dispatch — orders placed on a business day are dispatched that day, so you're not left waiting on a cracked screen.

That means the price difference between the two models is purely down to the panel technology and size — not a difference in quality assurance or aftercare.

Do You Sell a Screen for the Base iPhone 12 or iPhone 12 Pro?

Not currently. Our iPhone 12-generation range at present covers the iPhone 12 Mini and iPhone 12 Pro Max only. We don't list a screen for the standard iPhone 12 or iPhone 12 Pro right now, and rather than guess at a price or link you to the wrong part, we'd rather be upfront: if you need one of these two models, contact us directly and we can confirm current stock status and lead time. We'd rather tell you honestly than sell you something we can't back up.

Is It Worth Replacing an iPhone 12 Screen Yourself vs Paying a Repairer?

At £29.99–£51.72 for the part alone, self-repair is significantly cheaper than most third-party repair shop quotes, which commonly range from £60–£120+ for iPhone 12-series screen fitting once labour is included. If you're reasonably confident with small electronics and have the right tools (see our companion DIY guide), doing it yourself is the lower-cost route. If you'd rather not risk it, factor labour cost into your total budget — the part price above is your floor, not your ceiling.

How Do I Know Which iPhone 12 Model I Have?

Check Settings > General > About — the model name is listed there directly. Alternatively:

• iPhone 12 Mini has a 5.4-inch display, the smallest in the range, with a compact form factor.
• iPhone 12 Pro Max has a 6.7-inch display, the largest in the range, with a triple-camera module (three visible lenses) on the rear.

Getting this right matters — the two screens are not interchangeable, so ordering the correct part first time avoids a return and delay.

FAQ

Q: How much does an iPhone 12 Mini screen replacement cost in the UK? A: £29.99 for the Incell LCD screen — this is the only screen tier we currently stock for the Mini, and it's a single-variant listing, so there's nothing else to choose.

Q: How much does an iPhone 12 Pro Max screen replacement cost in the UK? A: £51.72 for the Soft OLED screen, which is the only tier we stock for this model.

Q: Why is the iPhone 12 Pro Max screen more expensive than the iPhone 12 Mini screen? A: Mainly because the Pro Max uses OLED display technology (self-emissive pixels, better contrast) versus the Mini's LCD panel, plus the Pro Max has a larger 6.7-inch panel versus the Mini's 5.4-inch panel. Both factors increase the cost of the replacement part.

Q: Do you sell a screen for the base iPhone 12 or iPhone 12 Pro? A: Not at present. We currently stock screens for the iPhone 12 Mini and iPhone 12 Pro Max only. Contact us to check current availability and lead time for the base iPhone 12 or iPhone 12 Pro.

Q: Does the price include fitting? A: No — the prices above are for the replacement part only. If you're fitting it yourself, see our step-by-step DIY guide. If you want it professionally fitted, a local repairer will typically add a labour charge on top of the part cost.

Q: Are these screens genuine Apple parts? A: These are aftermarket replacement screens manufactured to match the original specification (Incell LCD for Mini, Soft OLED for Pro Max), tested for touch accuracy, display quality, and Face ID/True Tone compatibility before dispatch. They are not sold as genuine Apple-branded parts.

Q: Is there a warranty on iPhone 12 screen replacements? A: Yes, both models carry a 12-month warranty covering manufacturing defects.

How to Replace It Yourself: Step-by-Step Guide

Yes — replacing an iPhone 12 screen is a moderate-difficulty repair that an experienced DIYer can complete in 45–75 minutes with the right tools, and it applies equally to the iPhone 12 Mini and iPhone 12 Pro Max (the process is essentially identical; only screw layout and screen size differ slightly). The main risks are cracking the display during removal, tearing a ribbon cable, and — specific to the iPhone 12 generation — overheating the MagSafe magnet ring built into the rear housing, which sits closer to the screen adhesive than on earlier iPhones. This guide walks through the full process safely, including the Face ID pairing consideration that catches out first-time repairers.

Difficulty, Time and Risk Summary

Factor	Detail
Difficulty	Moderate (4/5 — requires precision and patience)
Time required	45–75 minutes
Tools needed	Pentalobe P2 screwdriver, Phillips #000 screwdriver, suction cup, plastic opening picks, spudger, tweezers, heat gun or iOpener, adhesive strips
Key risk	Screen crack from excessive prying; ribbon cable tears; MagSafe ring overheating
Face ID	Retained if the original Face ID module is transferred correctly (see Step 6)

Get the Right Part Before You Start

• iPhone 12 Mini — Incell LCD Screen Replacement, £29.99
• iPhone 12 Pro Max — Soft OLED Screen Replacement, £51.72

Both come 100% tested before dispatch with a 12-month warranty, so a screen that arrives faulty is covered — not something you have to absorb as a DIY risk.

Tools You'll Need

• Pentalobe P2 screwdriver (for the two bottom-edge screws)
• Phillips #000 screwdriver (for internal bracket screws)
• Suction cup or screen-opening pliers
• Set of plastic opening picks (avoid metal tools near the battery)
• Spudger (plastic prying tool)
• Fine-tip tweezers
• Heat gun, heat mat, or iOpener-style heat pack
• Replacement pre-cut adhesive strips
• A well-lit, magnetic-free workspace (small screws are easy to lose)

Step-by-Step iPhone 12 Screen Replacement

Step 1: Power Off the Device Completely

Hold the side button and either volume button until the power-off slider appears, then power down fully. Never attempt this repair on a device that's still powered on — a live short across the battery connector is a real fire risk.

Step 2: Remove the Two Pentalobe Screws

Using the Pentalobe P2 driver, remove the two screws next to the Lightning port at the bottom edge of the phone. Keep them somewhere they won't roll away — they're easy to lose and specific to this location.

Step 3: Apply Heat and Create a Suction Seal

Apply gentle, even heat along the bottom edge and sides of the screen using a heat gun on a low setting or an iOpener, moving continuously rather than holding heat in one spot. Attach a suction cup near the bottom edge and lift gently to create a small gap, then work a plastic pick around the perimeter to release the adhesive.

This is the step most generic guides skip: the iPhone 12 range has a MagSafe magnet ring embedded in the rear housing, positioned closer to the display assembly than on the iPhone 11 or earlier models. Excessive or concentrated heat near the top and side edges during this step can weaken the magnet ring's adhesive bond or, in extreme cases, affect its magnetic strength. Keep heat moving, keep it low, and don't linger in one spot for more than a few seconds — this single detail is the difference between a clean opening and a MagSafe function that feels "weaker" afterwards.

Step 4: Open the Display Like a Book — Don't Fully Detach It Yet

Once the adhesive is released along the bottom and sides, lift the screen from the bottom edge like the page of a book, hinging from the top. Do not pull it away completely — several ribbon cables still connect the screen to the logic board.

Step 5: Disconnect the Battery First

Before touching the display connectors, locate and disconnect the battery connector using a plastic spudger. This is a critical safety step: disconnecting the battery first removes the risk of a short circuit while you're working near the display ribbon cables. Skipping this step is the single most common cause of DIY repair damage on iPhones.

Step 6: Disconnect the Display Ribbon Cables

With the battery safely disconnected, remove the small bracket covering the display connectors (usually 3–4 tiny Phillips screws) and gently disconnect the display and Face ID ribbon cables using the spudger. Do not attempt to transfer the Face ID sensor module to the new screen — on the iPhone 12 generation, the Face ID (TrueDepth) module and earpiece speaker assembly must be moved across from your original screen to the replacement screen for Face ID to keep working, since Face ID hardware is calibrated to the individual device, not the screen itself. Carefully transfer this small bracket and sensor assembly from the old screen to the new one before reconnecting.

Step 7: Transfer Remaining Small Parts

Check for any additional small brackets, screws, or the earpiece speaker mesh that need moving across from the old screen to the new one. Lay parts out in the order you remove them — a simple magnetic project mat or labelled tray prevents mix-ups.

Step 8: Connect the New Screen and Test Before Sealing

Reconnect the display ribbon cables and Face ID connector on the new screen, replace the small bracket, then power the phone on before applying adhesive or fully closing it. Check touch response across the full screen, colour accuracy, and that Face ID re-registers correctly. This test-before-seal step saves you from having to reopen a freshly-adhered screen if something's not connected properly.

Step 9: Reapply Adhesive and Seal the Display

Once you've confirmed everything works, remove the backing from the pre-cut adhesive strips, apply them around the perimeter, and press the screen down firmly from the top edge downward, working out any air bubbles.

Step 10: Replace the Pentalobe Screws

Refit the two Pentalobe screws at the bottom edge and give the phone a final function check — touch ID areas, cameras, speaker, and MagSafe (if you use a MagSafe charger or wallet) all worth a quick test.

iPhone 12 Mini vs Pro Max: What's Different in the Process?

The steps above apply to both models. The practical differences are minor:

• Screen size — the Pro Max's larger 6.7-inch OLED panel is more prone to flexing if handled roughly; the Mini's 5.4-inch LCD panel is more compact and slightly easier to manoeuvre in Step 4.
• Adhesive coverage — the larger Pro Max screen has more adhesive perimeter to heat evenly in Step 3, so budget a little more time on that step.
• Everything else — screw positions, connector layout, and the Face ID transfer process are the same across both models.

Do I Need to Recalibrate Anything After Replacing the Screen?

No manual calibration is required for touch or display on either model. Face ID will work automatically once the original sensor module is transferred correctly (Step 6) — it does not need re-pairing through Apple's system diagnostics for a standard screen swap.

What If I Don't Want to Risk It Myself?

If any of the above steps — particularly the battery disconnection or Face ID module transfer — feel outside your comfort zone, that's a reasonable place to stop. A professional repairer will have experience with the MagSafe ring heating issue and Face ID transfer specifically. The part itself — iPhone 12 Mini screen or iPhone 12 Pro Max screen — is the same either way; you're only saving or spending on labour.

FAQ

Q: How long does it take to replace an iPhone 12 screen? A: Around 45–75 minutes for someone doing it for the first time with the right tools, once you factor in careful heating and testing before sealing.

Q: Will I lose Face ID if I replace my iPhone 12 screen? A: Not if you transfer the original Face ID (TrueDepth) sensor module and earpiece bracket from your old screen to the new one, as covered in Step 6. Face ID hardware is tied to your specific device, not the screen glass.

Q: What tools do I need for an iPhone 12 screen replacement? A: A Pentalobe P2 screwdriver, Phillips #000 screwdriver, suction cup, plastic opening picks, spudger, tweezers, a heat source (heat gun or iOpener), and pre-cut adhesive strips.

Q: Is it true the iPhone 12's MagSafe ring can be damaged during screen removal? A: The magnet ring itself is durable, but excessive or concentrated heat during the adhesive-softening step (Step 3) — especially near the top and side edges — can weaken its adhesive bond to the rear housing or, in rare cases, degrade magnetic strength. Moving the heat source continuously and keeping it low avoids this.

Q: Do you sell a screen for the base iPhone 12 or iPhone 12 Pro to use with this guide? A: Not currently — this guide's linked parts cover the iPhone 12 Mini and iPhone 12 Pro Max only, which are the two iPhone 12-generation screens presently stocked. Contact the store to check availability for the base iPhone 12 or iPhone 12 Pro.

Q: Can I use this guide for both the iPhone 12 Mini and iPhone 12 Pro Max? A: Yes — the disassembly and reassembly process is essentially identical for both models. The only practical differences are screen size and the amount of adhesive to heat (see the comparison section above).

Which Screen Quality Should You Choose?

The iPhone 12 Mini's replacement screen uses Incell LCD technology at £29.99, while the iPhone 12 Pro Max's replacement screen uses Soft OLED technology at £51.72 — and the difference between them isn't just price, it's how the display physically produces an image. LCD panels shine a backlight through liquid crystal layers to create colour and brightness; OLED panels light each pixel individually with no backlight at all. That single architectural difference explains almost everything else in this comparison: contrast, black levels, battery draw, and cost.

There isn't a tiered "budget vs premium" choice within either individual model here — the Mini only has the Incell LCD option in stock, and the Pro Max only has the Soft OLED option in stock. So this isn't a "which quality tier should I pick" decision. It's a "what am I actually getting, and is it right for how I use my phone" decision — and that's what matters if you're choosing between repairing a Mini or a Pro Max, or just want to understand what you're paying for.

How Incell LCD and Soft OLED Actually Compare

Factor	Incell LCD (iPhone 12 Mini)	Soft OLED (iPhone 12 Pro Max)
Price	£29.99	£51.72
Screen size	5.4"	6.7"
Light source	Backlit (constant backlight behind the panel)	Self-emissive (each pixel lights independently)
Black levels	Greyish black — backlight can't fully switch off	True black — pixels switch off completely
Contrast ratio	Lower — limited by backlight bleed	Higher — deep blacks next to bright whites
Colour accuracy	Good, slightly cooler tones typical of LCD	Excellent, richer and warmer colour reproduction
Battery efficiency	Uses more power on dark content (backlight always on)	More efficient on dark content (dark pixels draw less power)
Viewing angles	Slightly more colour shift at extreme angles	More consistent colour at wide angles
Durability under pressure	Generally more resistant to minor pressure spots	Can show "pressure marks" if handled roughly

What Does This Mean for Everyday Use?

If you're repairing an iPhone 12 Mini: the Incell LCD panel is a sound, cost-effective match for the device it replaces — the original iPhone 12 Mini shipped with an OLED panel from Apple, but Incell LCD aftermarket parts are the practical, widely-used replacement standard for this model size and are significantly cheaper to produce and source than an OLED-equivalent replacement. You'll notice slightly less inky blacks in dark rooms or dark-mode apps compared to the original panel, but touch response, brightness, and day-to-day usability are not compromised.

If you're repairing an iPhone 12 Pro Max: the Soft OLED replacement matches the panel technology the device originally shipped with. You get the same deep-black, high-contrast look the Pro Max was designed around — which matters more on this model because Apple marketed the Pro Max's display specifically on its OLED contrast and HDR capability.

Does Panel Type Affect Battery Life?

Yes, marginally, and in different directions depending on what you're viewing. OLED panels (Pro Max) draw less power when displaying dark content — black pixels are switched off entirely rather than blocked by a backlight — which is why dark mode genuinely saves battery on OLED iPhones. LCD panels (Mini) run a constant backlight regardless of what's on screen, so dark mode has little to no battery benefit on this panel type. In everyday mixed use (a blend of light and dark content), the difference is small enough that it shouldn't be a deciding factor on its own — but it's worth knowing if you're a heavy dark-mode user.

Is Soft OLED "Better" Than Incell LCD?

In raw display quality terms — contrast, black levels, colour depth — yes, Soft OLED is the more capable technology, which is exactly why Apple used it on the higher-tier Pro Max originally and why the replacement part costs more. But "better" only matters relative to what the device needs and what you're comparing it against. An Incell LCD replacement on a Mini is not a downgrade from a hypothetical OLED Mini replacement — it's the sound, standard aftermarket option for that model, tested to the same 100%-tested-before-dispatch standard as every screen we sell, backed by the same 12-month warranty as the Pro Max's OLED screen.

Do You Sell a Screen for the Base iPhone 12 or iPhone 12 Pro?

No — not currently. Our iPhone 12-generation range covers the iPhone 12 Mini (Incell LCD, £29.99) and iPhone 12 Pro Max (Soft OLED, £51.72) only. We're not going to invent a listing or a price for the base iPhone 12 or iPhone 12 Pro just to fill a gap — if you need one of those two models, get in touch and we'll confirm current stock status honestly.

Which Should Influence Your Decision: Price or Panel Type?

If you already own an iPhone 12 Mini or Pro Max, the panel type isn't actually a choice — each model only has one screen tier available, matched to what that model needs. The comparison above is more useful if you're deciding between repairing your current device or weighing up the cost of each model's repair against the other (for example, if you're choosing between two second-hand iPhone 12-generation phones to buy, knowing the Mini uses LCD and the Pro Max uses OLED tells you what to expect from each display and what a future screen repair would cost on each.

FAQ

Q: Is the iPhone 12 Mini screen OEM or aftermarket? A: The iPhone 12 Mini Incell LCD screen sold here is an aftermarket replacement part, tested for touch response, display quality, and Face ID/True Tone compatibility before dispatch. It is not sold as a genuine Apple-branded part.

Q: Is the iPhone 12 Pro Max screen OEM or aftermarket? A: The iPhone 12 Pro Max Soft OLED screen is also an aftermarket replacement, matching the original OLED panel technology the device shipped with, and tested to the same standard before dispatch.

Q: Which is better, LCD or OLED, for an iPhone 12 screen replacement? A: OLED (Pro Max) offers deeper blacks, higher contrast, and better efficiency on dark content. LCD (Mini) is more cost-effective and still delivers accurate colour and reliable touch performance. Neither is "better" in absolute terms — it depends on which model you're repairing, since each model only has one panel type stocked.

Q: Can I get an OLED screen for my iPhone 12 Mini instead of LCD? A: We only stock the Incell LCD tier for the iPhone 12 Mini at present — there is no OLED alternative listed for this model in our current range.

Q: Do you sell a screen for the base iPhone 12 or iPhone 12 Pro? A: Not currently. Screens are stocked for the iPhone 12 Mini and iPhone 12 Pro Max only. Contact the store to check current availability for the base iPhone 12 or iPhone 12 Pro.

Q: Will an aftermarket screen affect Face ID or True Tone? A: No, provided the original Face ID sensor module is transferred correctly during fitting (see our DIY guide) and the True Tone-compatible screen is used, both of which apply to the parts sold here.
