Samsung Galaxy A52 Repair

From £49

No fix, no fee · 12-month warranty · Insured, tracked returns

Signs your Galaxy A52 needs a repair

  • Battery not lasting the day, or switching off with charge showing
  • Back cover lifting away from the phone (contact me before posting)
  • Charger loose, or charging on and off
  • Headphones or the microphone not working
  • Cracked or split back cover

A Samsung Galaxy A52 battery replacement costs £59 by post, a charging port £59 and a back cover £49, all with genuine Samsung parts and a 12-month warranty. Samsung's own price for an A52 5G battery is £79. I don't offer screen replacements on the A52, because of how its fingerprint reader works. The screen section below explains why, and where to go instead.

The Galaxy A52 5G went on sale in the UK in March 2021 at £399, and it's still one of the most-used mid-range Samsungs around. It has a 6.5-inch 120Hz Super AMOLED screen with the fingerprint reader underneath, a 4,500mAh battery with 25W charging, a plastic back, a headphone jack and an IP67 water-resistance rating. The 4G Galaxy A52 is the same phone with a 90Hz screen and no 5G, and it shares the same screen, battery and charging board.

Which Galaxy A52 do I have?

Go to Settings > About phone and check the model number. SM-A526B is the Galaxy A52 5G, the version Samsung sold in the UK. SM-A525F is the 4G Galaxy A52, which reached the UK as an import. Both are covered here and take the same battery and charging board. The Galaxy A52s (SM-A528B) is a different phone with its own page. I'll ask for the model number when you book, and your phone's colour for a back cover. This guide shows where to find it.

Galaxy A52 screen replacement

The A52's fingerprint reader is an optical sensor beneath the display. It's calibrated to the screen it sits under, and after a new screen it needs recalibrating with Samsung's own equipment. The A52 isn't part of Samsung's Self-Repair programme, so that calibration isn't available to independent repairers, and that's why I don't replace A52 screens. I'd rather tell you now than send your phone back with a fingerprint reader that may not work.

If your A52 screen is broken, Samsung's recommended price for an A52 5G screen is £139, and its repair service calibrates the fingerprint reader as part of the job. If you'd rather use another repairer, ask whether the screen is genuine and whether they can calibrate the fingerprint reader, and what happens if it doesn't work afterwards. This guide explains the fingerprint problem in more detail.

Fingerprint reader asking for calibration, on an undamaged screen? Several A52 owners reported the fingerprint reader stopping working, or asking for calibration, after a software update in 2022. If your screen is the original, delete and re-register your fingerprints and check for updates before assuming anything's broken.

Galaxy A52 battery replacement

By now most A52 batteries have been charged well over a thousand times, and they show it: charging twice a day, switching off with charge left, getting warm on the charger. You can check its condition in Samsung Members under Support > Phone diagnostics > Battery status, and this guide explains the result.

The A52's plastic back is glued to the frame, and the battery underneath is glued too. I soften the back's adhesive with heat, lift it off, work the battery out without bending it, fit a genuine Samsung 4,500mAh battery and reseal the back with new adhesive. The battery sits behind the screen assembly, so the job doesn't touch the screen or the fingerprint sensor, and I check the fingerprint reader before the phone goes back. It's £59, against Samsung's £79.

A new battery restores battery life. It won't make the phone faster, because lag is usually storage, apps or software. This guide to fast battery drain helps you tell which you've got.

If the back is lifting, stop and contact me first. A back that's lifting away from the phone can be failing adhesive, but it can also be a battery that has started to swell. Don't keep charging it, and contact me before posting it.

Galaxy A52 charging port repair

The A52's USB-C port sits on a small charging board at the bottom of the phone, together with the headphone jack and the lower microphone. A genuine replacement board fixes a worn, loose or damaged port, and also a dead headphone jack or a microphone callers can't hear, when the fault is on that board. The same board fits the A52 and A52 5G.

Before booking, try another cable and plug, and check the port for lint with a torch. The A52 is water-resistant, so if it says moisture has been detected, let it dry fully and try again. This checklist for a Galaxy A that won't charge goes through the rest. If it still won't charge reliably, the charging port repair is £59, and I test charging, fast charging, the headphone jack, the microphone and a data connection before it goes back.

Galaxy A52 back cover replacement

The A52 has a plastic back with a matte finish, glued to the frame. It's more likely to crack or split than shatter, and on an IP67 phone a damaged back also means the seal has gone. I fit a genuine Samsung back cover in your phone's colour and seal it with new adhesive. It's £49. I reseal every back with new adhesive, but once a phone has been opened I can't promise it keeps its IP67 rating, so treat it as not water-resistant after any repair.

Is it worth repairing a Galaxy A52?

For a battery, often yes. The A52 was a £399 phone and its screen, cameras and speakers still hold up well. Samsung ended security updates for it in 2025, so it no longer gets fixes for new security threats, and that's worth weighing if you bank or pay on it. A £59 battery can still give it a good while longer as an everyday phone. A Samsung screen at £139 is harder to justify. This guide explains what the end of updates means, and this one weighs up every model.

Frequently asked questions

Can you replace the screen on a Galaxy A52?
Not at the moment. Its fingerprint reader sits under the screen and has to be calibrated with Samsung's equipment after a new screen, which isn't available outside Samsung's repair network for this model. Samsung's recommended price for an A52 5G screen is £139.
How much does a Galaxy A52 battery replacement cost?
£59 by post, with a genuine Samsung battery and a 12-month warranty. Samsung's own price is £79.
Is the A52 the same as the A52s?
No. The A52s is a later, faster version with a different screen part. The batteries are the same, but the A52s has its own page and prices.
My A52 says the fingerprint sensor needs calibrating. Is it broken?
Not necessarily. Several A52 owners reported this after a 2022 update on phones that hadn't been repaired. Delete and re-register your fingerprints and check for updates. If the screen has been replaced with a copy, that's a more likely cause.
Will my A52 still be water-resistant after a repair?
I can't promise it. It's resealed with new adhesive, but any phone that's been opened can lose some of its original IP67 water resistance.
My A52's back is lifting. What should I do?
Stop charging it and contact me before posting it. It can be the adhesive giving way, but it can also be a swelling battery, which needs handling carefully.

About this service

How does your mail-in repair service work?
Three steps: book and pay for your repair online, post your item to me using the packing instructions I email you, and I repair it, test it, and send it back tracked. You'll get updates as it moves through each stage.
What is your no-fix-no-fee promise?
Payment is taken upfront at booking. If I can't fix your item, there's no repair fee — I refund what you paid, less £4.99 return postage to send it back to you. Assessment bookings work differently: the £4.99 covers return postage and comes off the repair if you go ahead, but isn't refunded if you decide not to or it can't be repaired.
Do your repairs come with a warranty?
Yes. Every repair carries a 12-month workmanship warranty against the same fault returning. If it does, I'll put it right.
How long will my repair take?
Most repairs are completed within 1-3 working days of arrival, then posted back by tracked post. If a part needs ordering, I'll tell you as soon as I've diagnosed it and give you a realistic date. Diagnostic-led jobs take a little longer if I'm waiting on your approval of a quote.
How do I package my item safely to post it?
I send clear packing guidance when you book. In short: wrap the item well, use plenty of padding, and a sturdy box — the return leg is insured and tracked, and good packing on the way in protects your item too.
Where do I send my item?
Your postage address is included in the confirmation email after you book — you don't post anything until you've booked, so your item is always matched to your order.
Do you cover the whole UK?
Yes — I run a mail-in repair service, so you can send your item from anywhere in the UK. There's nothing local you need to find.
What if my item turns out to be unrepairable?
I'll tell you honestly and, where the fault allows, offer an alternative. If I can't fix it, there's no repair fee — I refund what you paid, less £4.99 return postage to send it back to you.
