Samsung Galaxy S20 Ultra Repair in Adelaide – Bring Yours Back from the Dead...

Smashed? Slow? Sidelined? We See You, S20 Ultra Warriors.

If you’re reading this, odds are your beloved Samsung S20 Ultra isn’t looking so “Ultra” these days. Maybe it’s wearing a spiderweb screen, refusing to hold a charge, or making weird noises every time you plug in the charger. Or maybe you’re just clinging to it, praying it doesn’t quit before payday. Either way—breathe easy. You’re not alone.

This phone is a legend for a reason. We get it. You don’t want to chuck it, you just want it back. And that’s what we do at One-Systems Australia—from Norwood to Mount Barker, we’re the team that gets S20 Ultras back to their prime.

Who Are We?

We’re not a faceless franchise, we’re your neighbours: real techs, honest service, and a real sense of pride in every fix. We see S20 Ultras every single week and there’s almost nothing we can’t fix (except maybe that TikTok addiction).

Let’s talk about why your S20 Ultra deserves a second (or third, or fourth) life—and why you shouldn’t trust it with anyone but Adelaide’s best.

Why Is the Samsung S20 Ultra Still Worth Fixing in 2025?

Don’t Let TikTok Tell You Different

Every year, new phones come out, and everyone acts like last year’s model is ancient. Newsflash: the S20 Ultra is still a monster in 2025. If you have one, you know. This thing still outpaces plenty of so-called “flagships” (and looks damn good doing it). Here’s the reality:

• 6.9” Dynamic AMOLED 2X DisplayLet’s be honest—your S20 Ultra’s screen is better than half the TVs on the market. Crisp, sharp, and smoother than a Friday knock-off drink.
  

• 120Hz Refresh RateScrolling, gaming, binge-watching—you feel the difference. Most phones still don’t match this smoothness.
  

• 108MP Camera SystemYes, 108 megapixels. It’s not a gimmick; it’s why your Insta and Snapchat still pop.
  

• 5G SpeedStill blazing. Your mobile data is faster than half the home internet plans out there.
  

• Snapdragon 865/Exynos 990This chip still pulls weight in 2025. Unless you’re gaming with NASA, you’re covered.
  

So before you get suckered into dropping $1,500+ for something “new,” take a breath. Your S20 Ultra just needs some TLC. Save your cash, save your data, and skip the learning curve of a new device.

The Real-World Costs: Repair vs. Replace

The Money Side (Because Let’s Be Real)

• New S24 Ultra: $1,799+ (if you’re lucky)
  

• Trade-in S20 Ultra (cracked): $120–$250
  

• Quality Repair (screen, battery, port): $400–$500(Full repair, no data loss, your phone feels new again)
  

Math doesn’t lie: Repairing wins. Every single time.

What Makes Our S20 Ultra Repairs Different?

• Professional Tools & Clean WorkspaceStatic mats, ESD-safe gear, and clean benches—because dust and grease don’t belong in your phone.

• Fingerprint Sensor Transferred & CalibratedYour biometric unlock will work just like it should.

The S20 Ultra Screen Replacement – Step by Step

This is our most common repair, and we treat it like open-heart surgery (without the drama):

1. Diagnosis:We run display, touch, and sensor tests. Is it a display issue, touch, or something on the board?
   

2. Disassembly:The back glass is heated, carefully lifted, and set aside. Every screw and clip is stored safely.
   

3. Internal Disconnect:Battery disconnected. Motherboard and daughterboards accessed.
   

4. Old Screen Removal:Damaged display is separated from the frame, adhesives cleaned off.
   

5. Fingerprint Sensor Transfer:If needed, we carefully move your sensor and recalibrate.
   

6. New Screen Fitted:Fresh, high-quality AMOLED screen is installed, adhesives cured.

   
   

7. Reassembly:Everything put back, screws torqued, connectors clicked in.
   

8. Testing:Screen, touch, biometrics, sound, camera, charge, and buttons. All must pass.
   

9. Final Clean:We wipe it down—because fingerprints are for unlocking, not for display.

Time: 1–2 hours if we’ve got stock (which, let’s be honest, we usually do).Warranty: 6 months on screen and battery repairs.

S20 Ultra Battery Replacement – Why, When, and How

Batteries aren’t forever. Lithium cells start giving up after 2-3 years, even in “flagship” phones.

Signs you need a new battery:

• Phone dies at random percentages (it’s not you, it’s your battery)

• Gets hot for no reason

• Takes forever to charge, or never hits 100%

• Bulging back panel (that’s dangerous—get in ASAP)
  

How we fix it:

• Open the device using anti-static tools and proper heat pads

• Carefully disconnect and remove old battery

• Clean connectors, check for board corrosion or damage

• Install fresh, high-quality battery

• Seal the phone, test everything, and give it back with a real charge
  

Total time: Usually under 1 hour.No data loss: We don’t wipe or reset your phone.

Charging Port Repair – Why It Matters

If your S20 Ultra charges only when you threaten it with violence, or only in “that one weird angle,” the port is likely on its way out.

How we fix it:

• Disassemble the phone, remove the daughterboard and port

• Clean any debris, check for corrosion

• Solder in a new USB-C port, test for proper voltage

• Reassemble and check for quick charge compatibility
  

Don’t try to clean it with a toothpick—seriously. We’ve seen that story end in tears.

Camera & Back Glass – Keep the “Ultra” in S20 Ultra

S20 Ultra’s camera setup is iconic. Cracked lens or foggy shots? We replace with precision.Back glass smashed? We swap it out, matching the original finish. You get your style (and water-resistance) back.

What Else? We’re Also Your Data Safety Net

We know what matters most.

• Data always stays safe—no resets, no mystery wipes.

• If a reset is needed, we’ll warn you and walk you through backup options.

Tips for Keeping Your S20 Ultra Alive and Kicking

We love fixing phones—but we’d rather you didn’t have to see us too often! Here are our top tips:

• Get a solid case: Not the $2 eBay special. Invest in real protection.

• Use a tempered glass protector: Trust us, it’s way cheaper than a screen replacement.

• Don’t ignore small cracks: They always get bigger.

• Keep it dry: Water resistance isn’t water proof—leave it out of the bath.

• Charge smart: Avoid draining to 0% or using knock-off fast chargers.

• If it feels hot or looks swollen, shut it down and bring it in—safety first.
