The Galaxy S21 Ultra arrived in 2021, with a 6.8 inch Dynamic AMOLED 2X display and the Exynos 2100 chip. Charging is over USB-C and it unlocks with an ultrasonic fingerprint reader under the display. It is rated IP68. A very large curved screen and a big camera housing that wraps around the corner into the frame. The first Ultra to support the S Pen, though it has no slot for it. The one sold in Ireland is SM-G998B.

What this fixes
What a dead device diagnostic actually fixes.
- It shows the logo and restarts, over and overA boot loop. Software, storage or board, and they are not the same repair.
- It only works while plugged inAlmost always the battery, and one of the easier outcomes.
- It got hot and then diedWorth mentioning. Heat before failure narrows down where to look considerably.
- It vibrates but nothing appearsThe device is running. That points at the display or its connector rather than the power side.
- It shows a logo and restarts, over and overA boot loop. Often software and often recoverable without replacing anything.
- It stopped after an updateMore likely software than hardware, and usually the most recoverable outcome.
Before you spend anything
Is it definitely a power fault?
A dead phone is the one case where guessing is expensive, because every possible cause has a different price.
IfIt went dead after a drop
Something is disconnected or cracked inside. Usually recoverable, and worth telling us it was dropped.
IfIt went dead after getting wet
This is a liquid damage assessment, not a dead device diagnostic. Do not charge it in the meantime.
IfIt loops on the Apple logo
That can be software rather than hardware, and software is recoverable without replacing anything. Tell us if there is data on it you need before we try anything.
IfIt went in water first
Liquid damage takes priority. Do not charge it and do not keep trying to power it on.
IfYour data is the priority
Tell us before we start. Some routes preserve everything and some do not, and knowing your priority decides which one we try first.
If you are not sure which of these you have, that is what the free diagnostic is for. It costs nothing and it is the step that stops people paying for the wrong repair.
What parts do we fit?
Two tiers, and you choose knowing which is which: a genuine Samsung service part where one is made for this component, or premium aftermarket where none is. The warranty is 360 days on either.
Nobody here will call a part original when it is not. If what fits your phone is premium aftermarket, you hear that word at the counter rather than reading it on a docket afterwards.
What the Free diagnostic includes
- A full diagnostic on the bench, free
- A written answer on what has failed and what it costs
- No further work until you have approved the price
- No fee at all if we cannot fix it
Nothing extra gets done and charged for without you saying yes to it. Where the diagnostic turns up a second fault, the work stops there and you hear the price before it goes any further.
Dublin collection and return is available on weekdays if you cannot make it in. Nothing about the price or the cover changes because the courier brought it.
How we do it
From the counter to back in your hand.
Free diagnostic
Before a part is ordered we establish what has really gone wrong. It is free, and it is the reason people do not leave here having paid for the wrong thing.
You approve the price
You hear the number first. If it is not worth it to you, that is a perfectly good answer and it costs you nothing.
The repair is carried out
It stays in the shop. The work is done on our own bench by the technicians who do it every day of the week.
Bench testing
Nothing is handed back untested. The repaired part and its neighbours are all checked first.
Back in your hands
Yours again, from the counter or by courier, with 360 days of cover on the part and the work.
Before it goes back
What we test every time.
A repair is not finished when the part is fitted. It is finished when the things around it have been checked.
Power draw on the bench
Before the phone is switched on, because a short does more damage the moment it gets power.
Battery and charging circuit
The two most common causes and the two cheapest to put right.
Boot to a recovery state
Which separates a software problem from a hardware one before anything is replaced.
Storage integrity
Where the fault points that way, since it decides whether the data comes back.
Will my data be safe?
We are replacing a part, not reading a phone. Your photos, messages and accounts are not something this job touches.
The one place it comes up is testing. A repair is not finished until it has been used, and using a locked device means a passcode. You are welcome to withhold it, and we will tell you which checks that leaves undone rather than quietly skipping them. A passcode you do give us lives on a paper docket that gets shredded, never in a database.
Back it up first if you can. A device that has taken a knock has had its storage shaken whether or not anything looks wrong, and a backup is free insurance against the day that matters.
Is it still water resistant afterwards?
Treat the phone as no longer water resistant after any repair, including ours.
Apple's IP68 rating is measured on a brand new, factory sealed phone under controlled laboratory conditions. It is not a permanent property of the device. The seal degrades with age, heat and everyday knocks long before anybody opens it.
Opening a phone means cutting through that seal. We refit the display with fresh adhesive, which restores a physical seal and keeps ordinary splashes and rain out. What we will not do is tell you it is back to IP68, because we have no way to test that and neither does any independent shop in Ireland.
If your phone lives near water, say so when you book and we will talk you through what the adhesive does and does not cover.
The 360-day warranty
Every completed repair is covered for 360 days on the part and the workmanship. If the display we fitted fails, or the fitting was at fault, we put it right at no charge.
What it does not cover is a new accident. A phone dropped again after the repair, fresh physical damage, liquid damage, or a fault in a part we did not touch, all sit outside it. That is the same limit any honest repair warranty has.
No fix, no fee. The diagnostic is free, and if the repair does not happen you pay nothing.
Three ways to get it to us
- Walk in to Drumcondra4 Richmond Road, Dublin 3. No appointment. Mon to Sat 10:00 to 18:00, closed Sunday. Most phone screens and batteries done in 15 to 45 minutes while you wait.
- We collect and returnDoor to door across Dublin, Monday to Friday, usually 2 to 4 working days. The repair takes the same time; the courier is the difference.
- Send it in yourselfPost it to the shop with a tracked, insured service and a note with your number. We cannot cover a parcel in transit, and that is the honest trade-off for the route existing.
Same repair price and the same 360-day warranty on all three. The only thing that changes is how the device travels.

Asked all the time
Galaxy S21 Ultra screen questions.
We quote it after a free diagnostic, because the price depends on what we find. No fix, no fee, so if we cannot repair it you pay nothing.
Assessed first, then quoted. If the diagnostic turns up something else, or a part has to be ordered, we tell you before you commit rather than after.
Often, and tell us that is the priority before we start. Recovering data and repairing a phone are sometimes done in a different order, and choosing wrong can cost you both.
Batteries fail suddenly more often than people expect, particularly in cold weather and particularly once they are a few years old. It is worth checking before assuming the worst.
No. If it has looped or failed repeatedly, leave it off. Repeated attempts on a device that is failing under load do not help and occasionally make things worse.
Often yes, and say that is the priority before we start rather than after.
Usually same day. Where a fault only appears under load we sometimes have to leave it running, and we say so at the counter rather than leaving you wondering.

Customer reviews
Excellent customer service bought my samsung A54 best price in dublin.
As I'm a lawyer, I need a reliable phone. For me, it's an office extension in my pocket. I decided to buy a Samsung S23 Ultra. I live in Drumcondra so being aware of their excellent reputation locally, I visited iMend last week. The manager and assistant could not have been more helpful. I bought the phone and it exceeds my expectations. On checking, the price was the lowest in Dublin. Anyone who needs a phone or a small electronic product will be well looked after by iMend. Great people to deal with!
