Samsung Galaxy A90 5G Charging Port Repair Vienna
Does your Galaxy A90 5G get noticeably hot while charging or break off the 25W fast charge? That is not a battery but usually a charging-port problem – bent pins, oxidation on the contacts or a faulty USB controller chip on the flex. Reparo replaces the complete charging-port flex on the Galaxy A90 5G for a €59 fixed price in Vienna. 40–60 minutes of work, 6 months warranty on part and installation.

Typical charging-port problems on the Galaxy A90 5G
- The USB-C 3.1 port on the Galaxy A90 5G shows visibly bent or crooked pins after a forceful plug-in
- The Galaxy A90 5G no longer charges at all – even with a new cable and charger the battery stays at 0 %
- Your Galaxy A90 5G breaks off the 25W charge after a few minutes and drops to slow charging
- The PC connection on the Galaxy A90 5G keeps dropping – the data lines in the charging port are oxidised
- The USB-C 3.1 port on the Galaxy A90 5G is clogged with dust, lint or foreign objects – the cable no longer fits properly
- When a charging cable is plugged in, the Galaxy A90 5G briefly vibrates or beeps and immediately disconnects again
- After a short circuit in the port, the Galaxy A90 5G occasionally reports system restarts on plug-in – the result of a faulty USB controller in the flex
The Galaxy A90 5G launched in 2019 with a USB-C 3.1 charging port – 7 years later, with high usage counts, typical wear patterns appear: worn pins, oxidation on the data lines, loose solder joints on the flex. The USB-C 3.1 port supports up to 5 Gbit/s and 25W charging – the 24 contacts are mechanically stressed with every plug-in. Reparo replaces the complete charging-port unit, not just individual pins – that is considerably more durable. See also our Galaxy A90 5G repair overview with all available services.
How does the Galaxy A90 5G charging-port replacement work?
- Intake check and pin analysis
Under the microscope we check the USB-C 3.1 port on the Galaxy A90 5G for bent pins, foreign objects, oxidation and wear marks. With water contact, an additional pad check on the mainboard, so that we fix not just a symptom but the cause.
- Detach the back cover
On the Galaxy A90 5G we release the glued back cover with controlled heat (around 65 °C) and iFixit-compatible suction cups. The adhesive film on the frame is carefully removed so it can be replaced during reassembly.
- Disconnect the battery – safety first
Before anything happens on the charging circuit of the Galaxy A90 5G, the battery connector is disconnected from the mainboard. This prevents short circuits on the USB-C 3.1 controller and protects the flash storage from unexpected voltage spikes.
- Remove the old USB-C 3.1 flex in a controlled way
The charging-port unit on the Galaxy A90 5G is fixed to the mainboard via screws and a zero-insertion-force connector (incl. headphone or antenna contact). Release the flex, document the screw order, lift the old part out of the frame.
- Fit the new USB-C 3.1 charging port
The replacement flex (USB-C 3.1 charging-port flex with 5G antenna trace) is installed on the Galaxy A90 5G in exactly the same position. Screws to a defined torque, connector pressed home with controlled pressure. No bending, no pulling – wrong stress costs pin contact.
- Glue the housing back firmly
Fresh adhesive layers on the frame of the Galaxy A90 5G, back cover bonded with adjusted pressure. Curing time 15–20 minutes, after which the bond is stable for everyday use.
- Function test 25W charging + data pins
Final test with a calibrated charger on the Galaxy A90 5G: the charge protocol starts at 25W, pin contacts are checked for wobble behaviour, data transfer via USB to a test PC. Only when everything runs stable does the device go back to you.
Reparo works without customer access – your Galaxy A90 5G is picked up by courier in Vienna or sent in by post from the provinces.
Replacing the Galaxy A90 5G charging port – price, process and service details in Vienna
The charging port on the Galaxy A90 5G is the most mechanically stressed port of the device – every plug-in loads the USB-C 3.1 pins. After 2–3 years of daily use the mechanical limits show: pins wear out, data lines oxidise, solder joints on the flex tear. Reparo replaces it in Vienna for a €59 fixed price – certified replacement flex, 6 months warranty. Anyone who notices further problems with the device often benefits from a combined repair – see our separate A90 5G battery replacement for details.
Certified replacement flex vs. Samsung original – what do you get?
For the Galaxy A90 5G we fit charging ports that exactly match the Samsung flex: same USB-C 3.1 standard, same USB-PD certification, same form factor. Samsung service packs are only available through authorised Samsung service centres – our OEM-compatible parts measurably last just as long and carry the identical pin layout. You will find all further repair options on the Samsung repair overview.
Frequently asked questions about the Galaxy A90 5G charging-port replacement
What does the charging-port repair for the Galaxy A90 5G cost?
The charging-port repair costs €59 fixed price for the Galaxy A90 5G at Reparo in Vienna. Included: a new USB-C 3.1 charging port as a certified replacement flex, calibration of charge detection and 6 months warranty. The diagnostic check (25 EUR) is waived on repair.
How long does the charging-port replacement on the Galaxy A90 5G take?
40–60 minutes of work in the Reparo studio in Vienna. The pickup service in Vienna comes to you in the morning, the repair runs in the afternoon, return often the same day. With the send-in service from the provinces, we count 2–4 working days in total including shipping.
Does the Galaxy A90 5G charge again with 25W fast charging after the replacement?
Yes. The 25W fast charging on the Galaxy A90 5G runs via the USB-PD controller on the charging-port flex – exactly this part is replaced. Our replacement part has the identical USB-PD 3.0 certification as the original, so the full charging speed is available again. We test this after installation with a measuring device.
Does Reparo fit original or aftermarket charging ports on the Galaxy A90 5G?
On the Galaxy A90 5G we use certified Samsung-compatible charging ports – same USB-C 3.1 standard, same USB-PD power, same form factor. Original Samsung service-pack parts are only available through authorised Samsung service centres. Our alternatives come from specialised OEM manufacturers who also supply Samsung.
Is the Galaxy A90 5G waterproof again after the charging-port replacement?
The Galaxy A90 5G has no certified IP protection from the factory – replacing the charging port does not change that. During reassembly we apply new adhesive and sealing layers so that everyday moisture (light rain, sweat in a pocket) is still kept out. You should avoid direct submersion in general, however.
Is any data lost during the charging-port replacement on the Galaxy A90 5G?
No. Flash storage, Samsung account, SIM card and microSD (if present) are not disconnected during the charging-port replacement. Photos, WhatsApp chats, apps, Wi-Fi passwords – everything stays. We still recommend a Samsung Cloud backup before any repair as a standard precaution.
How does my Galaxy A90 5G get to the repair – pickup or send-in?
You have two options with the Galaxy A90 5G: pickup service in all 23 Vienna districts (1010–1230) – the courier picks it up, delivers it repaired, included in the €59 fixed price. Or send-in from all of Austria with insured shipping (Graz, Linz, Salzburg, Innsbruck, Klagenfurt) – return shipping also included, processing 2–4 working days.
Can I bring my Galaxy A90 5G to Reparo?
Reparo has no on-site customer access at the studio. The only options for the Galaxy A90 5G are the pickup service in Vienna (we come to you) or send-in by post from the provinces. This saves you the trip and often returns your device the same day.
How long is the warranty on the new charging port on the Galaxy A90 5G?
Six months on the charging port and the installation. If a contact problem, loose connection or fast-charge failure occurs again during this time, we replace it free of charge. Not covered: new mechanical damage from force or foreign objects such as keys or coins in the port.
Do I lose the Samsung warranty through the charging-port replacement on the Galaxy A90 5G?
The original Samsung warranty lapses with any third-party intervention. On the Galaxy A90 5G (model year 2019) the manufacturer warranty has usually expired anyway. The Reparo warranty on the new charging-port flex applies for 6 months in parallel and is valid Austria-wide.
Can I first clean the charging port on the Galaxy A90 5G myself before doing the replacement?
Yes, with dust or lint, careful blowing out with compressed air or a dry wooden toothpick helps. Not recommended: needles, metal tools or damp cotton swabs – they bend pins or cause short circuits. If cleaning does not help or the cable still wobbles afterwards, the port is mechanically worn out – then a replacement is the only solution.
My Galaxy A90 5G had water contact and no longer charges – is that a pure charging-port case?
Sometimes yes, sometimes not. With water contact, moisture often settles first on the USB-C 3.1 pins and corrodes there. If only the charging port is affected, a replacement for €59 is enough. With corrosion on the mainboard an additional ultrasonic bath is needed – we check that in the diagnosis (25 EUR, waived on repair) on the Galaxy A90 5G.
How do I tell whether the charging port on the Galaxy A90 5G is really faulty or just the cable?
Test at least two other original cables and chargers on the Galaxy A90 5G. If it charges cleanly with none of them, the fault is in the USB-C 3.1 port. Extra hint: if wobbling the cable changes the charge, it is almost certainly the port. In doubt we check it in the paid diagnosis (25 EUR, waived on repair) – safer than permanently buying the wrong cable.
Is the charging-port replacement on the Galaxy A90 5G still worth it in 2026?
The Galaxy A90 5G from 2019 is currently still supplied with security updates by Samsung – check the update status directly on samsung.com. Charging-port repair €59 vs. a comparable used device from around €120, plus setup, new 2FA, data migration. The repair is the economically better choice in almost all cases.
What does the diagnosis on the Galaxy A90 5G cost if I want it checked first?
The diagnosis costs 25 EUR and is fully waived with a repair order. On the Galaxy A90 5G we check loose connection, pin geometry, USB controller chip and the behaviour during fast charging (25W). After that you get a fixed-price estimate and can decide freely. No obligation to repair.
