Change modelThe Samsung Galaxy S21 is a popular device: nice design and good value. But it’s not protected against mechanical damage — a cracked screen or back glass happens most often. FIXNOW repairs your Galaxy S21 in Antwerp or Wolvertem; with our large stock of parts, usually the same day.

What issues bring a Galaxy S21 in to FIXNOW?
The Galaxy S21 has been in use for a few years now, and that shows in more than just its appearance. A drop from a bike or a table remains the most common reason the device ends up with us, but with age, the battery and charging port also come into play more often. These are the issues we see most:
- Screen showing cracks or shattered glass after a drop
- Battery draining noticeably faster than before
- Device that no longer charges, or only at a certain cable angle
- Forgotten PIN code, pattern lock, or Google account leaving the device locked
- Rear camera glass cracked or scratched
Galaxy S21 screen replacement: what are the options?
For the Galaxy S21, we work with a complete screen module: a repair limited to just the outer glass is not an option for this device. The frame, camera, and side buttons are left untouched; only the damaged screen is replaced with a new one. You can read more about this under Full screen replacement.
We also fit a new battery without affecting your photos, contacts, or apps: these simply stay in place during the procedure, since it’s a hardware intervention and not a reset of the device. More about this step under Battery replacement.
A visit to FIXNOW in Antwerp or Wolvertem starts with a brief check of the device, so you know beforehand exactly what the procedure involves. If you live further away, you can also send in your Galaxy S21 for repair.
Repair or replace?
A new screen or a new battery is generally a lot cheaper than buying a new device, especially when the rest of the Galaxy S21 still works fine. Your data, apps, and settings stay on the device, unlike switching to a new model, where you’d have to set everything up again.
Not sure what makes the most sense for your Galaxy S21? At FIXNOW, we’ll look together with you at exactly what’s going on, so you can make an informed choice between repairing and replacing.

Frequently asked questions
The most common screen issues on the Samsung Galaxy S21 are:
- Cracked glass — the screen glass shows cracks or breaks after a fall.
- Lines on the screen — vertical or horizontal streaks on the display.
- Black spots — dark spots in the image that get bigger over time.
- Touch no longer works — the screen doesn’t respond or responds poorly to touch.
If the image or touch no longer works correctly, a new display module is the solution: it fully restores the image and touch.

Very good job in 1 hour, change battery Samsung S-23 ultra for good price, great job
Broke my laptop in class, walked in 3 hours later with no appointment and my screen was fixed the next day. Great and open communication about the procedure and price. Definitely recommend!!

Breaking your laptop mid-class is a rough moment, so we're glad you could just walk in without an appointment. We'd always rather talk you through the procedure and the price upfront than leave you guessing, and getting a laptop screen repair in Antwerp done by the next day is exactly what we hoped for here on the Wiegstraat.
