Typical back cover damage on the Galaxy S21 Ultra
- Long cracks run diagonally across the back of your Galaxy S21 Ultra after a drop onto the corner
- The camera bump has glass chips – the phone rocks when you set it down
- Wireless charging cuts out or stops, and the device heats up on the Qi pad
- The back panel is lifting partly away from the aluminium frame – a gap is visible
- Edge splinters near the lower section catch and cut during everyday handling
- A spider-web pattern radiating from a central point marks the impact spot
A damaged back cover is more than just looks – once the adhesive frame is loosened, moisture seeps into the device and can cause mainboard damage. Our Galaxy S21 Ultra repair overview shows you every other service if additional damage is present.
How does the Galaxy S21 Ultra back cover replacement work at Reparo?
- Incoming diagnosis of the back cover damage
Your Galaxy S21 Ultra is checked for the type and extent of the damage: back glass only? Camera lens affected too? Qi coil accessible? We document it with photos and draw up a concrete plan.
- Releasing the back cover under controlled heat
The glass adhesive frame is warmed to around 70 °C – with a precision heating mat, not a hot-air gun. The damaged back cover lifts away evenly without putting pressure on the frame.
- Removing the old part and adhesive residue
The broken glass is taken off completely and glass splinters are cleared from the frame. Old adhesive is dissolved with 99% isopropyl alcohol and special spudgers – without scratching the aluminium frame.
- Checking the camera lens and Qi coil
On the Galaxy S21 Ultra the camera lens glasses and the wireless-charging coil sit beneath the back cover. We check both for damage, replace them if needed (agreed separately) and set them back into their original position.
- Bonding the new back cover properly
The OEM part is fixed to the frame with original Samsung adhesive strips. Defined contact pressure, 30 minutes of curing time – the sealing values are then back to factory spec.
- Final test and quality assurance
Wireless-charging test (if the model supports it), camera test shots, fit check on the frame, rear-finish inspection. You get your Galaxy S21 Ultra back looking as good as new.
Reparo works without on-site customer access – your Galaxy S21 Ultra is collected by courier in Vienna or sent in insured from the provinces.
Replacing the Galaxy S21 Ultra back cover – process, price and durability in Vienna
Around 15–20% of all Samsung repairs are back cover damage. On the Galaxy S21 Ultra the fault usually shows up after a drop onto asphalt or a kerb. Replacement at Reparo: EUR 189 fixed price in 1–2 business days, including a Qi-coil check and a glass back with chemical hardening (Gorilla Glass).
The Galaxy S21 Ultra back cover is made of chemically hardened glass – resistant to everyday scratches, but the glass breaks under hard drops. The replacement involves warming and releasing the adhesive seam at the frame, removing the old back cover, refitting the Qi coil (checked separately) and properly re-bonding it with original IP68 adhesive strips. Reparo handles this in Vienna for EUR 189 fixed price in 1–2 business days. Buying a new Galaxy S21 Ultra costs considerably more – the repair is the smarter choice when everything else on the device still works. See also the Samsung repair overview.

Frequently asked questions about the Galaxy S21 Ultra back cover replacement
What does the back cover replacement cost for the Galaxy S21 Ultra in Vienna?
The Galaxy S21 Ultra back cover replacement costs EUR 189 fixed price at Reparo in Vienna. Included in the price: the original or OEM back cover part (glass), fresh adhesive strips for the IP68 frame, Qi coil checked, calibration and a 6-month warranty. Diagnosis (EUR 25) is waived if you go ahead with the repair.
Why does the back glass break so easily on the Galaxy S21 Ultra?
The Galaxy S21 Ultra back cover is a material compromise between hardness and weight – a glass back with chemical hardening (Gorilla Glass Victus or similar). The glass shrugs off everyday scratches, but under impact drops onto edges it still breaks. Typical triggers: a fall from your trouser pocket onto tiles, an edge hit on a kerb, pressure from objects sliding around in the car. The replacement is usually faster and cheaper than buying new.
Which symptoms bring customers to us with the Galaxy S21 Ultra back cover?
Most common on the Galaxy S21 Ultra: a glass back with cracks running from the camera area to the edge, or a lifted rim. Sometimes the camera lens in the back cover has broken too – then we replace it as part of the back cover job or check the camera sensor separately. Every symptom is recorded precisely during diagnosis before any parts are ordered.
Does more than just the glass need replacing on the Galaxy S21 Ultra?
If the cracks are only in the rear glass, replacing the back cover unit along with the adhesive frame is usually enough. But if the drop also hit the camera module, the Qi coil or the frame, we check those components during diagnosis (EUR 25, waived on repair) and give you a clear quote before we start. On the Galaxy S21 Ultra the rule is: we fit nothing that isn't needed.
Is the display damaged during the Galaxy S21 Ultra back cover replacement?
No. Unlike a battery replacement, for the back cover we go into the device from the rear – the display stays completely untouched. We warm the adhesive frame to 70–80 °C with a special heating mat, release the damaged glass with flat carbon spudgers and bond the new part. Your Galaxy S21 Ultra screen stays exactly as it was.
Does the IP68 water protection stay intact on the Galaxy S21 Ultra after the back cover replacement?
Yes. With every back cover replacement we renew the complete IP68 adhesive frame all the way around. After proper fitting your Galaxy S21 Ultra reaches the same water and dust protection as from the factory again – brief submersion up to 1.5 m depth, 30 minutes. We generally advise against active diving or swimming after any housing intervention.
Does wireless charging work after the back cover replacement on the Galaxy S21 Ultra?
Yes. The Galaxy S21 Ultra's Qi charging coil sits directly behind the back cover – during the replacement we refit the coil and then check that charging works at the original speed. If the coil was damaged by the drop, it is replaced separately (cost after diagnosis). Without additional damage, wireless charging is the same after the replacement as before.
How long does the Galaxy S21 Ultra back cover replacement take at Reparo?
The pure working time on the Galaxy S21 Ultra is around 60–90 minutes. The total turnaround is 1–2 business days, because the new adhesive frame needs around 30 minutes of curing time before the device can be delivered again. We keep replacement parts in stock for the most common Samsung models; for special colours, 1 business day may be added for procurement.
Is the pickup service in Vienna included for the Galaxy S21 Ultra back cover replacement?
Yes. For the Galaxy S21 Ultra our courier drives to all 23 Vienna districts from Monday to Friday. You book a pickup window online (9 am–6 pm), we collect the device at your home or office and deliver it back after 1–2 business days. Courier costs are included in the EUR 189 fixed price – no extra fee.
Can I send the Galaxy S21 Ultra in from the provinces?
Yes. Customers from Graz, Salzburg, Linz, Innsbruck, Bregenz, Klagenfurt or St. Pölten send the Galaxy S21 Ultra in insured by post. After booking we send a shipping guide, and after the replacement the device goes back insured. Diagnosis EUR 25 (waived on repair), all other costs are included in the EUR 189 fixed price.
Can I drop the Galaxy S21 Ultra off at Reparo in person?
Reparo has no on-site customer access in Vienna. The two options for the Galaxy S21 Ultra back cover replacement: pickup service by our courier (within Vienna) or insured send-in service (from anywhere in Austria). Both options have the same fixed price of EUR 189.
Is any data lost during the Galaxy S21 Ultra back cover replacement?
No. We only work on the housing – the mainboard, storage, SIM card and Samsung account are not disconnected. Photos, apps, Wi-Fi passwords and settings all stay fully intact. We still recommend a Samsung Cloud backup before any repair (free, 5 minutes via the Samsung account settings).
Original Samsung back cover or aftermarket on the Galaxy S21 Ultra?
We fit high-quality OEM back covers that match the original Samsung parts in colour, material and fit. Original service-pack parts are only available through authorised Samsung service centres. For certain special colours of the Galaxy S21 Ultra we check in advance whether the replacement part is available – standard colours are in stock.
How long does the warranty on the new Galaxy S21 Ultra back cover last?
Six months on materials and fitting. If the new part lifts from the frame in that time or shows manufacturing cracks, we replace it free of charge. Not covered: new drop damage, water damage from improper use, or mechanical impact on the new glass. The warranty applies Austria-wide.
Is the back cover replacement on the Galaxy S21 Ultra even worth it?
Yes. A used Galaxy S21 Ultra with an intact back cover costs considerably more on the market than the EUR 189 replacement. On top of that comes the hassle: data migration, new setup, lost 2FA tokens. The replacement keeps the device looking as good as new – and the Galaxy S21 Ultra hardware keeps working for years. Buying new only pays off when several components are faulty at once.
