Screen Repair on the Galaxy S21 Ultra
The Galaxy S21 Ultra has a 6.8-inch Dynamic AMOLED 2X screen. On an AMOLED Galaxy the display and the touch glass are bonded into one unit, so a full screen repair replaces both together. Its fingerprint reader sits under the screen, so after a replacement check that it unlocks the phone before you leave the counter. The Galaxy S21 Ultra is one of the models named in reports of the Samsung green line fault. If that's what you're seeing, our green line guide explains when it's a warranty claim.

Samsung Galaxy S21 Ultra screen repair — questions people actually ask
- How much to replace a Samsung Galaxy S21 Ultra screen in Singapore?
- S$130 nett for the Grade AAA option. That's what you pay at the counter — the price on this page is the price, with nothing added to it, and it was last checked 21 Oct 2026. Message us and we'll confirm the cover on this one before you come down.
- My Samsung Galaxy S21 Ultra still works but the screen is black or cracked. Is that the same repair?
- Usually, yes. Glass, touch layer and display are bonded into one part on nearly every modern phone, so a black screen with a working phone underneath and a cracked screen that still displays both come down to replacing that assembly. It's worth doing while the display still works — a crack lets in dust and moisture, and once those reach the layers you get dead touch or lines across the picture instead of a clean fix.
- How long does it take to replace a Samsung Galaxy S21 Ultra screen?
- Same day for most Samsung Galaxy S21 Ultra jobs, often within the hour. Send us a message first so we can check the screen for your model is in stock — that's what turns a wait into a second trip.
- What is Grade AAA, and how is it different from an original screen?
- Grade AAA is a high-grade aftermarket panel. Against an original it's very close on brightness and colour and usually indistinguishable in normal use; originals still win at the extremes — peak brightness outdoors, and true-black on an OLED. It costs noticeably less, which is the whole point of the grade. The grades are set out in full here, and where both exist, both are priced.
- Do you wipe the Samsung Galaxy S21 Ultra, and do you need my passcode?
- No, nothing gets wiped. Your photos, apps, messages and settings stay exactly where they are — a screen repair doesn't touch storage. We ask for a passcode only to test the phone after the repair; if you'd rather not hand it over, unlock it for us at the counter and stay while we check. A backup before you hand it over is still sensible, because that's true before anyone opens a phone.
- Where can I get same-day Samsung Galaxy S21 Ultra screen repair in Singapore?
- At any of our four shops — Chinatown, Tampines, Jurong and Yishun — open 11am–9pm daily, no appointment needed. Message +65 9456 6455 before you set off and we'll confirm the part for your Samsung Galaxy S21 Ultra is on the shelf, which is what decides whether it's same-day. Every other repair we do for this model is listed on the Samsung Galaxy S21 Ultra repair page.

Samsung Galaxy S21 Ultra Screen Replacement (Grade AAA) in Singapore
Grade AAA is the lower-cost screen we fit, and we carry it for a short list of Galaxy S and Note models, the Samsung Galaxy S21 Ultra among them. The faults are the ones that bring any Galaxy in: glass shattered from a drop, a corner that took a knock and turned black underneath, a line down the middle, a strip where touch has stopped answering. What changes is how much you want to spend putting it right.
Both of our grades replace the whole front screen as one part, glass and touch layer included, and both are fitted the same way. Grade AAA costs less. Original Grade is our higher grade and costs more, and it's what we fit unless you choose otherwise. If the Samsung Galaxy S21 Ultra is becoming a spare, or it's going to a parent who mostly calls and messages, Grade AAA is a sensible spend. If it's still your main phone for a good while, compare both prices in the table above first.
Before You Bring In Your Samsung Galaxy S21 Ultra
- Run a finger slowly across the whole screen, edges included, and note any spot where touch drops out.
- Make sure you know your screen lock PIN or pattern. If your model reads your fingerprint through the screen, you'll register it again after the repair, and the phone asks for the PIN first.
- Message us your exact model on WhatsApp first so we can confirm a Grade AAA screen for it is in stock.
What Happens to Your Samsung Galaxy S21 Ultra at Citri Mobile
- We check the phone free and confirm the screen is the only thing that needs replacing.
- You see the nett price for Grade AAA and for Original Grade side by side, and you choose before we open anything.
- The new screen goes in, usually the same day once the part for your model is here.
- We test touch edge to edge, the picture on light and dark backgrounds, the earpiece and the front camera, then hand it to you to sign in.
- You check it at the counter, and it goes home with you.
Every Galaxy we carry a Grade AAA screen for is listed on our Samsung Grade AAA screen replacement page. For the bigger picture, what a Samsung screen costs to fix in Singapore walks through the whole range, foldables included.
