After replacing the screen or glass, we always recommend our clients apply a protective glass. An additional protective layer will protect your device from scratches and reduce the likelihood of shattering during impact. This is a small investment that will help save in the future.
How quickly is the Samsung Galaxy S21 Ultra (G998) repaired?
The replacement of the Samsung Galaxy S21 Ultra glass or Dynamic AMOLED 2X screen typically takes from 1 to 3 hours at our service. The back cover, made of Gorilla Glass Victus, takes 2–4 hours due to specific adhesive curing processes, while the upgrade of the capacious 5000 mAh battery is done within 1–2 hours. As we have all the necessary parts in stock, we ensure maximum efficiency and the highest quality of assembly while maintaining the device’s integrity.
Do you provide a warranty for Samsung S series repairs?
For Samsung Galaxy S21 Ultra repairs we provide a 3-month warranty. We use specialized equipment that allows us to achieve factory precision, ensuring long-term stability of the device.
Do you replace the Samsung Galaxy S21 Ultra camera glass?
Yes, we professionally replace the rear camera glass module of the Samsung Galaxy S21 Ultra. This model features a complex four-camera system (including a 108 MP main sensor and a periscope telephoto lens), so if the protective glass is damaged, we strongly recommend covering it with tape as soon as possible. This will protect sensitive focusing mechanisms and optical image stabilization (OIS) from dust and moisture, thus avoiding the costly replacement of the entire camera block.
What is the difference between screen and glass replacement in this model?
The Samsung Galaxy S21 Ultra uses an advanced curved screen with an integrated ultrasonic fingerprint sensor. If your screen matrix is undamaged (no black spots, vertical lines, or flickering), we can perform only the restoration of the outer glass using a special OCA technology. Glass replacement is only possible if the original 120Hz LTPO screen is functioning perfectly. If the matrix is damaged, the complete screen module is replaced.
Will the screen quality degrade after glass replacement?
Absolutely not. Since your original Samsung Dynamic AMOLED 2X matrix is preserved during the procedure, color reproduction, HDR10+ support, and 1500 nits brightness remain unchanged. Your phone will display exactly the same quality as before the damage.
Can you provide a replacement phone during repairs?
We understand that the Samsung Galaxy S21 Ultra is your main tool for work and leisure. Therefore, while our technicians are rejuvenating your device, we provide a loan smartphone free of charge for the duration of the repair.
Recommendation for owners
After the screen repair or glass restoration of the Samsung Galaxy S21 Ultra, we always recommend ensuring additional protection. Due to the weight of the device and its curved edges, the impact force often lands directly on the glass. Applying a high-quality hybrid protective glass or a special film effectively absorbs mechanical energy and protects the valuable matrix from repeated shattering and scratches.

Samsung Galaxy S21 Ultra repair services
Screen glass replacement
We perform precise glass separation from the matrix. If the 6.8-inch screen has no color artifacts, we replace only the outer layer, preserving the original Samsung component. Otherwise, we install a new complete module.
Battery replacement
We install the original 5000 mAh capacity Li-Ion battery (model EB-BG998ABY, 19.25 Wh). Replacement is recommended when the capacity drops below 80%, the phone heats up during charging, or it unexpectedly shuts down in low temperatures.
