The Galaxy S23 Ultra arrived in 2023, with a Dynamic AMOLED 2X display. It charges over USB-C and it unlocks with an ultrasonic fingerprint reader under the display. It is rated IP68. Four rear cameras and the S Pen, with a curved display. Ireland gets the SM-S918B.

What this fixes
Why people book a dead device diagnostic.
- It only works while plugged inAlmost always the battery, and one of the easier outcomes.
- 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 gets warm on the charger and never startsSomething is drawing current. Worth a diagnostic before anything else is tried.
- It works only with the charger connectedThe battery is finished, and that is the cheapest of the possible causes.
- It died and will not respond to any button combinationCould be the battery, the port or the board. Guessing here is what costs people money.
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 works only while plugged into power
That is the battery, and it is the cheapest thing this can be.
IfIt went dead after a drop
Something is disconnected or cracked inside. Usually recoverable, and worth telling us it was dropped.
IfIt went in water first
Liquid damage takes priority. Do not charge it and do not keep trying to power it on.
IfIt was dropped just before
That changes where we look first, so say it at the counter.
IfThe battery is years old
Check that before anything else. A cell that cannot hold voltage under load produces exactly this.
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?
Genuine Samsung service parts where they exist for the component, and premium aftermarket where they do not. You are told which one your repair uses before you agree to it, and the 360-day warranty is the same either way.
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.
A collection and return across Dublin can be added when you book. The repair price and the warranty are the same either way.
How we do it
From the counter to back in your hand.
Free diagnostic
Nothing is opened or ordered until we know what failed. There is no charge for this and no obligation to go ahead afterwards.
You approve the price
You get the exact figure before any work starts. Nothing else happens without asking you first.
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
We test what we replaced and everything that sits beside it, because that is where a rushed repair shows up.
Back in your hands
Collected from Drumcondra, or returned to your door if we picked it up. Covered for 360 days.
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.
Charge behaviour on a known good supply
Because a failed charger and a failed device look identical from the outside.
Boot to a recovery state
Which separates a software problem from a hardware one before anything is replaced.
What happens to what is on it?
Nothing about this repair requires reading what is on the device, and nobody here does.
Testing is a different matter. To prove a repair works we have to turn the device on and use it, which sometimes means asking for your passcode. Say no if you prefer and we will show you exactly which checks we cannot complete without it. Where you do give it, it is written on the paper docket and the docket is shredded. There is deliberately no field for a passcode in our system.
Take a backup before you come in. It is free, it takes two minutes on a device that still works, and it is the one thing nobody regrets having done.
What about the water resistance?
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.

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.
No. It is free, you are told what has failed and what it costs, and there is no fee if we cannot fix it.
Usually not, which is the good news. Chargers, batteries and software account for most of them.
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.
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
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!
