Back Glass Replacement on the Galaxy S21 Plus
The Galaxy S21 Plus has a glass back. It also charges wirelessly through that glass. Once a crack spreads it stops being cosmetic, because the back is part of the seal behind the phone's IP68 rating. Replacing it means heating off the cracked panel and fitting a new one with fresh adhesive.

Inside Our Workshop: Samsung Galaxy S21 Plus back glass replacement in Singapore
Samsung Galaxy S21 Plus back glass replacement — questions people actually ask
- How much to replace a Samsung Galaxy S21 Plus back glass in Singapore?
- S$40 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.
- Is a cracked back glass on the Samsung Galaxy S21 Plus worth repairing?
- It's worth it if the crack is spreading or shedding, because the sharp edges catch on everything and the frame underneath is exposed to dust and water. Back glass on most modern phones is laser-separated from the frame, so it's a workshop job rather than something you can do at home with a heat gun. If it's a hairline in one corner and the phone is otherwise sound, it's a cosmetic call and we'll say so.
- How long does it take to replace a Samsung Galaxy S21 Plus back glass?
- Same day for most Samsung Galaxy S21 Plus jobs, often within the hour. Send us a message first so we can check the back glass 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 back glass?
- 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 Plus, and do you need my passcode?
- No, nothing gets wiped. Your photos, apps, messages and settings stay exactly where they are — a back glass replacement 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 Plus back glass replacement 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 Plus 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 Plus repair page.

Samsung Galaxy S21 Plus Back Glass Replacement (Grade AAA) in Singapore
Most people live with a cracked back for a while. Then the spiderweb from a corner drop starts shedding slivers that catch in a pocket or nick a finger, and it's time. Sometimes the back isn't cracked at all but lifting away from the frame. That is often a swollen battery pushing it out, so we check for it first: a new back laid over a swollen battery won't stay put.
This repair fits a Grade AAA back, our lower-cost grade for this part. On most Galaxy S and Note phones the back is glass, glued to the frame over the battery, so we warm it, lift the cracked panel off, clear away the old adhesive and bond the new back on with fresh adhesive. Most A-series phones have a plastic back, and on those that's the panel we replace. Once the back of a Samsung Galaxy S21 Plus has been off, the factory IP rating can't be promised, by us or by anyone who opens a phone.
Before You Bring In Your Samsung Galaxy S21 Plus
- Put a strip of clear tape over the cracks so loose pieces stay on the phone and off your fingers.
- Look at the camera lenses on the back. If one is cracked as well, tell us so we can check it in the same visit.
- If the back is bulging rather than cracked, stop charging the phone and bring it in.
- Message us your model and its colour first so we can check what we have in stock.
What Happens to Your Samsung Galaxy S21 Plus at Citri Mobile
- A free check of the back, the battery under it and the camera lenses.
- The nett price for a Grade AAA back, agreed before we start.
- The cracked back comes off, the frame is cleaned and the new back is bonded on. It's usually done the same day once the part for your model is here.
- We check the back sits flat and even, the cameras still take clean photos and the Samsung Galaxy S21 Plus charges.
- You collect it and run a thumb along the edges yourself.
