GPS/location services
Main article: Using location services
The DIGNO 3 has GPS built in, however due to the lack of Google Play Services most typical apps will either not provide a location or will not function. There also seems to be issues with the GPS working altogether, although the cause of this has yet to be determined.
USB HID
The phone does not support USB HID, meaning external devices, such as keyboards or mice, cannot be used via the USB port.
Audio over USB-C
The USB port on the device exclusively uses “Audio Accessory Mode” for audio, which only allows audio as an analog signal7. 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 source code for the kernel and open source components of the operating system for all variants of the DIGNO 3.
Attempts to root the device have yet to be successful. Although it has allegedly been done8.
Updates
Kyocera supplies OTA (over-the-air) updates in Japan.

The DIGNO 3 require an active Softbank SIM card to update, even when connected to Japan via a VPN.
Third-party applications
Main article: Third-party apps
The DIGNO 3 does not come with any way to download third-party apps by default, due to this apps need to be installed using Android Debug Bridge (ADB) from a computer. Many third party apps have partial navigability using the “D-Pad”, but usually the cursor is required to interact with some elements. Due to the small screen size apps can not render properly at times, but this can be mitigated by changing the display size.
Variants
902KC
The 902KC is SoftBank's version of the DIGNO 3.
903KC
The 903KC is Y!mobile's version of the DIGNO 3.
904KC
Variant of the phone for business users. This variant does not have a camera, radio, or TV functionality. The keypad also has different buttons. Differences are noted in the supplementary manual provided by Softbank12.
It is sold with a charging cradle.
Notes
Model number
The full model number's for the 90XKC are formatted as: NPA20XKC.
NP stands for “New Product” and KC stands for “KyoCera”13.
Charging cradle
The DIGNO 3 has a charging cradle that is sold separately for the 902KC and 903KC, the Softbank manual lists the model number as “KYEAY1”, and the Y!mobile manual lists it as “KYEAZ1”.
The 904KC is sold with a charging cradle, the model number is uncertain.
The charging cradles do not support data transfer, and seem to be completely interchangeable between the DIGNO 3, DIGNO 4, and the Kyocera DIGNO Keitai Basic14.
