The Samsung Galaxy S21 Ultra is a popular device: nice design, a 6.8-inch 120Hz screen, and S Pen support. But it can’t handle a drop — a cracked screen is the most common problem with this model. FIXNOW repairs your Galaxy S21 Ultra in Antwerp or Wolvertem, often the same day.

What complaints bring a Galaxy S21 Ultra to FIXNOW?
The Galaxy S21 Ultra has been in use for several years now, and it shows on the device. With this model, these are the complaints that keep coming back:
- Screen cracks or shatters after a fall onto the street or tiles
- Display shows spots, coloured streaks, or a flicker that won’t disappear
- Battery drains noticeably faster than you’re used to
- Charging stops working, or only works when the cable sits at a specific angle
Replacing the Galaxy S21 Ultra screen: how does FIXNOW handle it?
On the Galaxy S21 Ultra, the glass and the AMOLED panel are bonded together as one piece. If the screen is cracked or the image itself is damaged, we replace the screen as a complete module. The camera, speakers and the rest of the device are left untouched.
If the battery needs replacing or your device struggles to charge, we first check where the problem really lies. Often a new battery is enough; sometimes the cause is the USB-C port itself, for example dust or a worn contact point. Your photos, apps and settings simply stay in place during this kind of repair.
You can book an appointment through the website or by phone, and you don’t have to come in yourself: if you don’t live nearby, you can also send in your device. If you’d rather come in person, you’re welcome at FIXNOW in Antwerp or Wolvertem.
Repair it or buy a new device?
A Galaxy S21 Ultra with a cracked screen or a tired battery often still works fine on every other front: the processor, camera and memory keep doing their job. A repair then costs you significantly less than a new device, and you don’t have to set anything up again or transfer your data. If you’re unsure whether a repair is still worth it, we’ll look at that together during your appointment.

Frequently asked questions
These are the most common screen problems on the Samsung Galaxy S21 Ultra:
- Cracked glass — cracks or tears across the screen.
- Lines or stripes on the display — the image shows coloured or black lines.
- Black spots — parts of the image disappear.
- Touch no longer responds — the screen does not register your touch or responds incorrectly.
When lines, spots or unresponsive touch occur, the display itself is damaged and a complete new display module is the solution: image and touch will work fully again. Is only the glass cracked and the image still working perfectly? Read the next question.

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.
