Samsung Galaxy S21 FE Repair

How long does it take to repair a Samsung Galaxy S21 FE phone?

The replacement of the glass or screen for the Samsung Galaxy S21 FE (model G990) usually takes about 1 to 3 hours in our service. Since this model has a sealed body with an IP68 resistance standard, the adhesive drying process is crucial for ensuring quality. Replacing the rear plastic (glass-tic) cover takes about 2–4 hours, while replacing the 4500 mAh battery takes an average of 1–2 hours. For Samsung Galaxy S21 FE repairs we provide a 3-month warranty.

Do you provide a warranty?

We take full responsibility for the durability of the installed components and the tightness of the work performed.

Do you change the camera glass?

Yes, we replace the rear camera glass for the Samsung Galaxy S21 FE. This model has a three-lens system, so damage to the glass can quickly ruin sensitive focusing mechanisms. If you notice a crack, we recommend covering it with tape immediately. This will protect the 12 MP main, 12 MP ultra-wide, and 8 MP telephoto cameras from dust and micro-scratches, thus avoiding the expensive replacement of the entire camera module.

What is the difference between screen and glass replacement?

In many cases, a full screen module replacement can be avoided by applying glass restoration technology. The replacement of the glass for the Samsung Galaxy S21 FE is only possible if the 6.4-inch Dynamic AMOLED 2X screen has no functional damage: no black spots, vertical lines, flickering, and the touchscreen responds in all areas. The screen matrix must also be original. If the display layer itself is damaged, the entire screen must be replaced.

Will the screen image quality deteriorate after the glass replacement?

Definitely not. When replacing only the glass, the factory Samsung Dynamic AMOLED 2X matrix remains in your phone. This means that HDR10+ support, 120Hz refresh rate, and original color reproduction remain identical to when you purchased the new device.

Can you provide a replacement phone?

Yes, we understand that the Samsung Galaxy S21 FE is your daily work and entertainment tool, so we provide a replacement phone for free during the repair period to keep you connected.

Recommendation

After a successful screen or glass replacement, we strongly recommend applying high-quality tempered glass or hydrogel film. The Samsung Galaxy S21 FE screen is flat, so the protection adheres very reliably. This not only protects against scratches but also absorbs impact energy during a fall, thus protecting the main glass from re-breaking.

Samsung Galaxy S21 FE repair services

Glass replacement: If only the outer glass is cracked and the display works perfectly, we separate the glass and preserve the original display module. This helps reduce the cost.

Full screen replacement: If the display panel has black spots, flickering or coloured stripes, we replace the entire 6.4-inch module, with or without a frame, restoring its 2340 x 1080 px resolution.

Battery replacement: We replace the original 4500 mAh lithium-ion (Li-Ion) battery when it wears out. Warning signs include overheating, shutdowns at 15-20%, a battery pushing out the rear cover or more than 500-800 charge cycles.

Charging port (USB-C) repair: We replace the USB Type-C 3.2 connector if the phone will not charge, a computer cannot recognise it or fast charging fails.

Button and connector replacement: We repair faulty power and volume buttons and address SIM card slot issues.

Camera module replacement: We replace the main 12 MP module or 32 MP selfie camera if photos are blurry, autofocus fails or spots appear in images.

Speaker and microphone repair: We clean or replace the upper and lower speakers if sound is quiet, crackles or stops altogether.

Motherboard soldering: We carry out complex BGA soldering, replace power controllers (IC) and clean corrosion caused by liquid exposure.

Common faults and their solutions

Battery swelling: Non-original chargers or temperature fluctuations can cause the battery to swell and push out the rear cover. We safely replace it with a new EB-BG990ABY battery.

Rapid discharge: This is often caused by chemical wear inside the battery. We recommend replacing it and avoiding complete discharge to 0% in future.

USB-C port faults: Moisture or accumulated dust are common causes. We replace the port and check the charging circuit.

Screen artifacts: Green or pink lines on the AMOLED screen can result from manufacturing defects or physical damage. They require replacement of the entire screen module.

Fingerprint scanner faults: If the scanner stopped working after glass replacement elsewhere, we calibrate it or reposition the sensor.
