Poco M4 Pro 4G Screen Replacement Vienna
Has the AMOLED colour calibration on your Poco M4 Pro 4G drifted – whites tipping into yellow, blue looking washed-out and grey instead of deep, skin tones turning pale? After four years of AMOLED ageing, or an impact that knocks out the calibration IC, the 6.43-inch panel no longer hits its original colour accuracy. Reparo replaces the display in Vienna – EUR 139 fixed price, done in 2–3 hours, 6-month warranty.
Poco M4 Pro 4G Screen Replacement – Price & Service
- Certified 6.43" AMOLED replacement display with 90Hz
- Fitting plus a full touch and colour calibration
- Colour profiles re-calibrated – white neutral again
- All data, apps and MIUI settings stay intact
- 6-month warranty on display and labour
- Pickup service in Vienna or mail-in from Austria
Diagnostic check EUR 25 – waived on repair. Price confirmed before we start.
What to expect from the display replacement
The Poco M4 Pro 4G is opened, the burned-in or cracked 6.43-inch AMOLED is removed and swapped for a tested replacement panel. After fitting: a touch test across the whole surface, colour calibration in the MIUI menu and a check of the 90Hz refresh rate.
With the Vienna pickup service it takes 2–3 hours – the phone is usually returned the same or next business day. For a mail-in from Salzburg, Innsbruck, Graz or Klagenfurt: 2–4 business days from when it arrives.
Whites are neutral again, blue reaches its familiar depth, skin tones look natural. The 90Hz refresh rate runs smoothly and the touchscreen responds across the whole panel. All your photos, apps and settings stay untouched.
EUR 139 fixed price – incl. AMOLED replacement panel, fitting and a 6-month warranty. The price is EUR 20 above the Poco M4 Pro 5G because the 4G model uses AMOLED rather than LCD. The EUR 25 diagnosis is waived once you place the order.
Typical display faults on the Poco M4 Pro 4G
A web page background suddenly looks cream rather than white, a blank notepad has a warm beige tint. After several years the AMOLED colour calibration has lost its reference values – white no longer reaches its original neutrality.
In landscape shots the sky looks flat and shifted towards grey, a rich deep blue can no longer be reproduced. The calibration IC on the display board may be damaged after an impact – the voltage supply to individual colour channels is no longer precise.
Portraits in the gallery show faces washed-out or slightly reddish, gradients look stepped rather than smooth. After four years of constant use the 90Hz AMOLED loses panel accuracy – the loss is most visible in the midtones.
Visible cracks across the AMOLED, parts of the image black, lines running across the screen. The 6.43-inch panel is broken internally – a display replacement is the only lasting fix; a screen film or protector won't solve it.
The Poco M4 Pro 4G shows the picture as usual, but input is ignored or only registers on part of the surface. The AMOLED's touch layer is faulty – a full panel replacement restores the complete touch function.
The phone rings, vibrates and charges, but the screen stays dark. The ribbon connection between the AMOLED and the mainboard is broken, or the panel is faulty internally. A display replacement reliably fixes both scenarios.

How the Poco M4 Pro 4G screen replacement works
-
Pickup in Vienna or mail-in from Austria
Book an appointment or call – we collect your Poco M4 Pro 4G in Vienna, or you post it to our workshop in 1020 Vienna. No shop visit needed, no walk-in possible.
-
Colour and function diagnosis
We measure white point, blue depth and colour-gamut coverage on the 6.43-inch AMOLED, and check whether only the panel is affected or the calibration IC as well. Diagnosis EUR 25, waived once you place the order.
-
Open the Poco M4 Pro 4G and remove the AMOLED
The 4G housing is distinguished from the 5G model (different frame width). The panel adhesive is released with heat and the faulty AMOLED removed – without damaging the mid-frame or the camera brackets.
-
Fit the new AMOLED panel
The tested replacement AMOLED with 90Hz is fitted, the connectors securely locked and the panel firmly bonded. The battery is then reconnected and the phone is started up.
-
Colour calibration and 90Hz test
In the MIUI display menu the colour space is re-calibrated – white point, saturation and contrast set to reference values. The 90Hz refresh rate is enabled in settings and checked in a scroll test.
-
Return and warranty card
The Poco M4 Pro 4G comes back – usually the same day for a Vienna pickup, by insured return shipping for a mail-in. A 6-month warranty on panel and fitting from handover.
No shop visit possible – Reparo works exclusively via the Vienna pickup service or mail-in from anywhere in Austria.
Is the AMOLED replacement on the Poco M4 Pro 4G still worth it?
The Poco M4 Pro 4G launched in 2022 – a budget device with an AMOLED display that was still rather mid-range for its time. Even in 2026 the 6.43" panel with 90Hz, DCI-P3 colour gamut and 1000 nits peak brightness delivers image quality that is hard to beat in this price bracket. For EUR 139 you get that AMOLED quality back. A current Xiaomi 14 starts at EUR 899.
- EUR 139 fixed price – incl. AMOLED panel and fitting
- All photos, apps and WhatsApp chats stay
- 6-month warranty on panel and labour
- Done in 2–3 hours
- Pickup service in Vienna or mail-in
- From EUR 899 (Xiaomi 14, new)
- Data transfer, app logins and 2FA to set up again
- Selling or disposing of the old device
- Getting used to a new MIUI/HyperOS interface
With a clear colour loss or a cracked panel and no other damage to the Poco M4 Pro 4G, the AMOLED replacement for EUR 139 is clearly the cheaper choice.
Which AMOLED does Reparo fit into the Poco M4 Pro 4G?
We fit a certified AMOLED replacement panel with a 6.43-inch diagonal and a 90Hz refresh rate – mechanically and electrically compatible with the original panel of the Poco M4 Pro 4G (identical to the Redmi Note 11 4G). Before fitting we check white point, colour saturation and touch response. After the swap the colour space is re-calibrated in the MIUI display menu, so white is neutral, blue is deep and skin tones look natural.
Poco M4 Pro 4G AMOLED – why colours lose precision over the years
The Poco M4 Pro 4G was Xiaomi's 2022 attempt to bring AMOLED technology to the budget class. The 6.43" panel with a 90Hz refresh rate was a genuine selling point in its price segment back then – and it's the reason the phone still makes sense four years on. Organic LEDs, however, have a physical trait: they age unevenly. Blue LEDs lose brightness faster than red or green ones – after three to four years of constant use the white point shifts visibly towards warm and blue looks washed-out.
The second typical case: an impact on a hard floor damages the calibration IC on the display board. The panel still lights up, but the precise voltage control for individual colour channels fails. The result is pale skin tones, grey sky shots and a yellow cast in documents. The difference compared with the Mi 9 (a green-red cast across everything) or the Poco X5 5G (a purple cast at the edge) is that on the M4 Pro 4G no single colour dominates – instead all colours lose saturation. The only lasting fix is a display replacement.
Poco M4 Pro 4G vs. Poco M4 Pro 5G – a different display
Worth knowing: the Poco M4 Pro 4G uses AMOLED with 90Hz, while the Poco M4 Pro 5G uses an LCD panel with 90Hz. The two models have completely different parts – and different prices. AMOLED is more expensive to make, so the display replacement on the 4G model costs EUR 139, on the 5G model only EUR 119. If you're unsure which variant you have: under Settings → About phone → Model you'll find the exact name. The 4G model typically carries the code designation '21091116AG'.
Redmi Note 11 twin – a compact AMOLED at 6.43"
The Poco M4 Pro 4G shares its hardware base with the Redmi Note 11 4G – AMOLED, battery and camera modules are compatible. Compared with today's Xiaomi devices at 6.7"+, the 6.43" display feels almost compact: the phone fits in a trouser pocket, is usable one-handed and weighs just 179 grams. For users who don't want a phablet, that's an argument for repair rather than a new purchase – current mid-range Xiaomi phones almost all measure over 6.6".

Frequently asked questions about the Poco M4 Pro 4G screen replacement
Display replacement for the Poco M4 Pro 4G – what's the price at Reparo?
EUR 139 fixed price – incl. a certified AMOLED replacement panel with 90Hz, professional fitting, colour calibration and a 6-month warranty. The price is EUR 20 above the Poco M4 Pro 5G because the 4G model uses AMOLED rather than LCD. The EUR 25 diagnosis is waived on repair.
Why do whites on the Poco M4 Pro 4G suddenly look yellowish?
The blue LEDs in the AMOLED panel age faster than the red and green ones – after three to four years of constant use the white point shifts towards warm. A second cause is a damaged calibration IC after an impact. A display replacement restores neutral white reproduction.
How long does the AMOLED replacement on the Poco M4 Pro 4G take?
2–3 hours with the Vienna pickup service – the phone is usually returned the same or next business day. For a mail-in from other federal states: 2–4 business days from arrival, including return time.
Is there a difference from the Poco M4 Pro 5G display?
Yes, a fundamental one: the Poco M4 Pro 4G uses AMOLED with 90Hz, the Poco M4 Pro 5G an LCD panel. The panels aren't compatible – different connectors, different dimensions. That's why the 4G replacement costs EUR 139 and the 5G replacement EUR 119. The model variant is shown under Settings → About phone.
Does Reparo use the same display as the Redmi Note 11 4G?
Yes. The Poco M4 Pro 4G and Redmi Note 11 4G are hardware twins – the AMOLED is mechanically and electrically identical. Reparo uses the same parts for both models, which keeps availability and price stable.
Can I drop off the Poco M4 Pro 4G for the display replacement?
No walk-in. Reparo works exclusively via the pickup service in Vienna or by mail-in from anywhere in Austria. Book an appointment online or give us a quick call – everything else runs without a shop visit.
How does the pickup service in Vienna work?
Give your address when booking and choose a time slot – Reparo comes to you, takes the Poco M4 Pro 4G to the workshop in 1020 Vienna and brings it back after the display replacement. Fully contactless if you wish. Pickup starts from EUR 7.90.
Can I send the Poco M4 Pro 4G in from Salzburg, Tyrol or Styria?
Yes, from anywhere in Austria. After booking the appointment you receive the shipping address and packaging tips. Insured return by post, with free return shipping; the total turnaround from handover to the post is about 4–6 business days.
Will my data stay intact during the display replacement?
Yes. Only the AMOLED panel is swapped – storage, photos, WhatsApp chats, MIUI settings and installed apps remain fully untouched. A backup beforehand is still sensible.
What warranty does Reparo give on the new AMOLED?
6 months on panel and fitting from the handover date. For problems without new external damage – such as pixel faults, colour loss or touch failure – the display is reworked or replaced again free of charge.
Does Reparo use original or premium aftermarket AMOLEDs?
We use certified AMOLED aftermarket panels that are mechanically and electrically identical to the original and are checked for white point, colour saturation and touch response before fitting. In everyday use they deliver results on a par with the original panel.
Is repair worth it, or better a new Xiaomi?
For EUR 139 the 6.43" AMOLED with 90Hz stays, while a current Xiaomi 14 starts at EUR 899. Anyone wanting a compact device under 180 grams will find few alternatives at Xiaomi today – the current models are all over 6.6". The display replacement makes more sense financially and ergonomically.
What if the Poco M4 Pro 4G has a display failure from water?
The Poco M4 Pro 4G only has splash protection (IP53), not true water resistance. After water ingress we first diagnose whether only the panel or also mainboard components are affected – diagnosis EUR 25, waived on repair. Water damage treatment from EUR 79.
What does the diagnosis cost on its own, without a repair?
EUR 25. We check the AMOLED condition, the calibration IC, touch function and other components and provide a cost estimate. If you go ahead with the display repair at Reparo, the diagnosis is fully credited – you only pay EUR 139.
What if there's other damage to the Poco M4 Pro 4G besides the AMOLED?
During the diagnosis we also check the battery (5000 mAh), the USB-C charging port (33W), the cameras and the speakers. You receive a full cost estimate – repairs are only carried out after your approval. Combined repairs often lower the overall effort.
