====== Kyocera GRATINA KYF44  ======

A model targeted towards corporate users for [[wp>KDDI]]. This model has a version with the camera removed as well as the SD card slot disabled. This phone also features the same [[wp>System on chip|SoC]] as the [[.:kyocera_digno_keitai_4:]], but seems to have the body of the [[.:kyocera_gratina_kyf42:]]. Due to the SoC it may be possible to root the phone with MTKClient or by other means.

=== Audio over USB-C ===

The USB port on the device exclusively uses "Audio Accessory Mode" for audio, which only allows audio as an analog signal[(https://www.soundguys.com/usb-audio-explained-18563/)]. This boils down to the device not supporting audio cables that have a DAC (Digital-to-Analog Converter) anywhere within them. Many USB-C to 3.5mm adapters have a DAC built into them, and will not function. Adapters of without DACs may be found online, but may not advertise this.

Inline remotes have yet to be tested.


===== Operating system =====

Kyocera releases [[http://android-dev.kyocera.co.jp/source/|source code]] for the kernel and open source components of the operating system. Both models seem to use the same version codes and updates.
