Fairphone 4 Repair Vienna

Repairing the Fairphone 4 display & screen

On the Fairphone 4 the display is a 6.3-inch IPS LCD, and that is exactly what makes the swap affordable — no OLED premium surcharge like on its successor. Typical faults: the glass is cracked, the touchscreen only reacts in spots, or the screen shows streaks after a drop. In the workshop we release the display module with the supplied Phillips screwdriver and swap it as a whole part — no heat gun, no soldering iron, done in around 30 minutes. A screen replacement on the Fairphone 4 costs 149 EUR with a certified module, 6 months warranty included.

Replacing the Fairphone 4 battery — modular in 30 seconds

The 3,905 mAh battery in the Fairphone 4 is built in as its own module and can be swapped without tools. That is rare worldwide — most smartphones glue the battery in, while on the Fairphone 4 you simply click the module out. After three to four years of use every lithium battery loses noticeable capacity, and that is exactly when the swap pays off — you get full runtime back without having to buy a new device. Battery swap in the workshop: 69 EUR, original battery module, all data stays fully intact.

Fairphone 4 back cover & further repairs

The back of the Fairphone 4 is a removable click cover made of polymer — not glued glass like on an iPhone. That has a big advantage: no glass shatter after every other drop. If the cover is scratched or cracked, we swap it for 39 EUR — and you can even change the colour, since Fairphone offers the Coloured Cover in several variants. Camera (89 EUR), USB-C charging port (49 EUR) and speaker (59 EUR) are individually replaceable modules too.

Fairphone 4 will not start, keeps restarting — software repair & bootloop fix

When your Fairphone 4 will not start anymore (fairphone 4 will not start), keeps restarting (fairphone 4 keeps restarting) or is stuck in a bootloop, hardware is not always to blame — often it is a failed OS update or a corrupt system image. Symptom triage: the Fairphone 4 reaches the boot logo and then keeps restarting (fairphone 4 restarts again and again) = classic bootloop, software repair solves it. The screen stays completely black and does not react to the power button = more likely a deeply discharged battery or a mainboard fault (diagnostic check 25 EUR clarifies). We resolve bootloops, do data recovery before the factory reset and on request also install custom ROMs like /e/OS or LineageOS. Software repair from 30 EUR.

Is a Fairphone 4 repair still worth it in 2026?

The Fairphone 4 was released in 2021 and still receives security updates directly from the manufacturer through 2030 — five years after the purchase date, almost unique across the industry. A repair is therefore almost always economically sensible: screen swap 149 EUR vs. a used device from 280 EUR, plus a new battery for 69 EUR — you practically get a „new“ Fairphone 4, but keep all your data and save resources. That was exactly the idea behind the modular design.
