Samsung Galaxy S21+ Screen Replacement UK — Complete Guide (2026)
If your Samsung Galaxy S21+ has a cracked, flickering, or unresponsive display, you're not alone. Launched in January 2021, the S21+ was one of Samsung's flagship handsets that year, featuring a 6.7-inch Dynamic AMOLED 2X display with a smooth 120Hz adaptive refresh rate. Several years on, plenty of these phones are still in daily use — and screens remain one of the most common parts to fail, whether from a drop, a knock, or simple wear.
This guide covers everything UK owners need to know about replacing a Samsung Galaxy S21+ screen in 2026: what a replacement costs, how the repair options compare, a step-by-step DIY walkthrough for confident owners, and an honest look at whether repairing a now-older flagship still makes financial sense.

Because the S21+ uses an AMOLED panel, even a small crack in the glass can eventually affect touch response or cause discolouration as moisture or pressure reaches the display layers underneath. It's worth replacing a cracked screen sooner rather than later to avoid this kind of secondary damage.
Is It Still Worth Repairing a Galaxy S21+ in 2026?
The S21+ is now a several-years-old flagship, so it's a fair question: does it make financial sense to repair the screen, or is it time to upgrade? In most cases, repairing still stacks up well. A screen replacement typically costs a fraction of a new mid-range or flagship phone, and if the rest of the handset — battery health, cameras, chassis — is in good condition, a new screen can comfortably extend the phone's useful life by another year or two. The main exceptions are phones with multiple other faults (failing battery, damaged charging port, water damage) where the combined repair cost starts to approach the value of a replacement device. If your S21+ is otherwise healthy, a screen repair is usually the more cost-effective choice over buying new.

How to Replace a Samsung Galaxy S21+ Screen: Step-by-Step
This is an intermediate-to-advanced DIY repair. Take your time, work on a clean, static-safe surface, and only proceed if you're comfortable handling small components and adhesive.
- Power off the phone and remove any case or screen protector.
- Apply gentle heat around the screen edges (a heat gun on low or a dedicated heating pad) to soften the adhesive holding the display in place.
- Insert a suction cup near the bottom edge of the screen and create a small gap.
- Slide a plastic opening pick into the gap and carefully work it around the perimeter to release the adhesive, avoiding the top area where internal cables are routed.
- Lift the screen carefully and prop it open, then disconnect the display and fingerprint sensor ribbon cables from the logic board.
- Remove the old screen completely and clean any leftover adhesive from the frame using isopropyl alcohol.
- Transfer any small components (such as the earpiece speaker or brackets, if not included on your replacement) from the old screen to the new one, if required.
- Connect the new OLED screen with frame, reattaching the display and fingerprint ribbon cables securely.
- Test before sealing — power the phone on and check touch response, colour accuracy, and the fingerprint sensor across the full screen.
- Apply new adhesive strips around the frame and press the screen firmly into place, working from one edge across to the other.
- Reinstall any screws or brackets removed during disassembly, then leave the phone under light, even pressure for a few minutes to help the adhesive bond.
Tools typically needed: heat gun or heating pad, suction cup, plastic opening picks, precision screwdriver set, tweezers, isopropyl alcohol, adhesive strips.
Frequently Asked Questions
How much does it cost to replace a Samsung Galaxy S21+ screen in the UK?
A genuine-fit OLED replacement screen with frame from The Repair Plus costs £76.99 if you're fitting it yourself. Independent shop repairs typically run £90–£150 (estimate), while manufacturer repairs are generally the most expensive, often £150–£250+ (estimate), depending on location and warranty status.
Can I replace the Galaxy S21+ screen myself?
Yes, with the right tools and care. The process involves removing the old adhesive-sealed screen, disconnecting the display and fingerprint sensor cables, fitting the new screen, and resealing with fresh adhesive. It's a moderately advanced repair — if you haven't opened a phone before, watch a full walkthrough video first or consider a professional fitting.
Will a third-party replacement screen affect the fingerprint sensor?
A correctly fitted OLED replacement with frame, like the one stocked by The Repair Plus, is designed to work with the S21+'s in-display fingerprint sensor. Always test the fingerprint sensor before fully sealing the screen to confirm it's registering properly.
Is it still worth repairing a Galaxy S21+ instead of buying a new phone?
In most cases, yes. A screen replacement costs a small fraction of a new device, and if the rest of the phone — battery, cameras, chassis — is in good shape, a new screen can add another year or two of useful life. It's less worthwhile if the phone has multiple other faults that would add significantly to the total repair cost.
How long does a Galaxy S21+ screen replacement take?
A professional repair shop typically completes the job within an hour or two, depending on workload. A careful DIY repair usually takes 45–90 minutes, including adhesive curing time, for someone doing it for the first time.
Does replacing the screen affect water resistance?
Yes, potentially. The original factory seal is designed for consistent water resistance, and any screen replacement — DIY or professional — can reduce this protection unless fresh, correctly applied adhesive fully reseals the frame. Avoid exposing the phone to water immediately after a repair.
