Contents

Major upgrades from the predecessor include a larger display, better camera with optical image stabilization, improved selfie camera, 5G support, IP54 dust and splash protection and MIL810G certification, USB-C port, bigger battery, 20W fast charging among other changes. [1] [4]

It comes with Android 11 “Red Velvet Cake” with promised two major Android updates [5] (Android 12 “Snow Cone” and Android 13 “Tiramisu”) and up to 5 years of warranty. [6] [ better source needed ]

Materials

The Fairphone 4 is made with Fairtrade-certified gold, aluminum from Aluminium Stewardship Initiative (ASI) Performance Standard certified vendors, fair tungsten from Rwanda, recycled tin, rare earth minerals, and plastics. [6]

Modular design

The phone's modular design is constructed of seven modules, making it easier to repair than most smartphones. The rear of the phone can be removed without using tools. Having removed the rear, the battery can be lifted out and replaced. The display is easily removed using a regular Phillips #00 screwdriver, and the modules are held in using only press fit sockets. [7]

Operating systems

CalyxOS 4.2.7, Android 13, is available for the Fairphone 4 as of December 2022. [8] In April 2022, CalyxOS provided "test builds" of Android 12L. [9] /e/ supports Fairphone 4, but Ron Amadeo at Ars Technica in April 2020 warned, "they'll most likely be on an old version of Android". [10]

Reception

The Fairphone 4 received mostly positive reviews praising its guarantee of software support until 2025 and up to 5 years of warranty and improvements over its predecessor. However, the lack of a headphone jack was criticized, along with the occasional sluggish performance and the quality of the camera and fingerprint sensor. [11] [4] [12] [13]

GrapheneOS criticized Fairphone 4 for being shipped with publicly available private keys for the firmware and stock operating system, causing security features such as verified boot and hardware keystore to break, and for not providing firmware updates on time. [14]
