Samsung Galaxy A21s Repair Vienna
The Galaxy A21s was a 2020 entry-level bestseller built around one headline spec — a 5,000 mAh battery in a EUR 179 phone, when most rivals stuck with 3,000 mAh at that price. 6.5 inch LCD, Exynos 850, 48 MP quad camera and a side-mounted fingerprint sensor in the power button. After 5 years of daily charging the battery is on its last legs and the LCD is cracked in plenty of units. Aftermarket LCD from EUR 99, battery EUR 59. Vienna pickup or send-in Austria-wide, EUR 25 diagnosis waived upon repair, 6-month warranty.

Galaxy A21s repair Vienna — the 5,000 mAh entry-level bestseller
The Galaxy A21s landed in June 2020 as Samsung’s entry-level workhorse for the year — a EUR 179 phone that bundled a 5,000 mAh battery (rare at this price in 2020), a 6.5 inch LCD, the Exynos 850 chipset, a 48 MP quad camera and a side-mounted fingerprint sensor in the power button. Samsung sold over 25 million A21s units worldwide, making it one of the best-selling Android phones of the year. In Vienna it became the go-to backup phone, the parents-phone and the student starter device. Six years later many A21s units are still in daily use — usually with a cracked LCD or a worn battery that needs a EUR 59 swap.
The 6.5 inch LCD and the drop pattern
The A21s LCD is on the bigger side of 2020 budget phones, which spreads drop force but means cracks travel further when they do start. Most cracks we see start at the lower-corner USB-C edge. EUR 99 aftermarket LCD swap brings back full 60 Hz touch precision and the side-fingerprint sensor in the power button stays active.
The 5,000 mAh cell and the slow degradation
The A21s charges at 15 W maximum, which is slower than newer phones — and that slow charging is exactly what keeps the 5,000 mAh cell alive longer. Most A21s units in Vienna still see 60 % capacity in 2026, but at that level the runtime drops to half a day. A EUR 59 battery swap is the cheapest meaningful upgrade we offer.
Side fingerprint and the back-cover repair
The A21s uses a side-mounted fingerprint sensor in the power button — the most reliable budget-phone sensor of 2020. The back-cover replacement preserves the quad-camera module and the 3.5 mm headphone jack (yes, the A21s still has one). EUR 59 with colour-matched replacement housing.
Vienna pickup or send-in Austria-wide
Reparo runs as a workshop, not a walk-in store. For A21s owners in Vienna we collect the device from your address — the same courier brings it back after the repair, usually within 24 hours of approval. Outside Vienna you ship the device to us with the insured return label we provide.
Diagnosis is EUR 25 and is fully waived once you approve the repair. You see the binding written quote in English before any work starts — no opaque labour line items, no surprises.
Frequently asked questions about Galaxy A21s repair
How much does a Galaxy A21s screen replacement cost in Vienna?
Samsung-original TFT LCD costs EUR 119, certified aftermarket LCD EUR 99. Both come with 6 months warranty and the side-mounted fingerprint in the power button stays fully functional after fitting.
Does the A21s have an IP rating?
No. The A21s has no IP certification. Keep it away from sinks, pools and rain. If water gets in, switch off immediately and arrange pickup or send-in for ultrasonic cleaning.
Is the A21s battery worth replacing in 2026?
Yes — almost always. After 5–6 years the 5,000 mAh cell typically holds 60 % capacity. A EUR 59 swap is our cheapest meaningful upgrade and restores a full day-and-a-half of runtime.
How long does an A21s screen replacement take?
1–2 working days in the workshop. The LCD with side-mounted fingerprint is straightforward to swap — no on-screen sensor calibration needed.
Does the A21s still have a headphone jack?
Yes. The A21s ships with a 3.5 mm headphone jack on the bottom edge. We test it after every screen, charging port and back-cover repair to make sure it still works cleanly.
Why is my A21s charging slowly?
Original charging was 15 W — not fast by modern standards. If charging takes more than 3 hours from empty to full, either the USB-C port has worn (EUR 59 swap) or the battery has degraded (EUR 59 swap).
Can I send the A21s in by post from outside Vienna?
Yes. Send-in service Austria-wide. EUR 25 diagnosis waived if you proceed, insured return courier included. Round trip 2–3 working days from Salzburg, Graz, Linz or Innsbruck.
Is my data safe during a Galaxy A21s repair?
For screen, battery, charging port and back cover repairs all data stays intact — storage chip is never touched. Samsung Cloud or Google One backup recommended beforehand.
Does the A21s still receive software updates?
No. Samsung stopped security patches for the A21s in 2023. Still runs Android 12 and is usable for messaging and calls, but is no longer the safest choice for sensitive banking apps.
Is it still worth repairing the A21s in 2026?
Yes when the repair cost is below the used-replacement price. Used A21s trades around EUR 60–90 in Vienna. EUR 99 LCD or EUR 59 battery makes sense if the device is otherwise intact.
Can I just bring the A21s to the workshop?
No — Reparo is a closed workshop without walk-in customer access. Use our free Vienna pickup courier or the Austria-wide send-in service with insured return label.
What warranty do I get on the A21s repair?
6 months on every part and labour, valid Austria-wide. Battery cell gets an extended 12-month warranty. Drops, water damage and physical abuse after the repair are not covered.
What is the difference between the A21s and A21 for repair?
The A21s came after the original A21 with a bigger 5,000 mAh battery and 48 MP main camera (the A21 had 16 MP and 4,000 mAh). Repair prices and procedures are very similar — same LCD layout, same side fingerprint.
What are the most common faults on the A21s?
Cracked LCD from drops (corner cracks travel along the long edge), battery degradation after 5–6 years, USB-C wear from daily charging, headphone jack getting loose. Water damage less common because owners use cases.
Do you speak English?
Yes. Reparo is Vienna’s English-speaking Samsung specialist — we work daily with UN City, OPEC, OSCE and embassy families. All communication, the quote and the warranty document are in English.
