What this hardware actually means
Editorial interpretation generated from the device's self-reported fields and our SoC tier database. Cross-reference with the raw fields below; if you spot a contradiction, please tell us.
Platform & performance positioning
The kddi KYF31 is built around the Snapdragon 210, a budget SoC from Qualcomm. It launched in 2015 on a TSMC 28nm LP process. Entry SoC for sub-$80 phones in the mid-2010s.
Legacy. Realistic use is limited to phone calls and SMS.
Day-to-day workload
1 GB of RAM is insufficient for modern Android. Display resolution is 854x480.
This record reflects Android API level 22 (5.1). Android 7 or older — effectively retired; very few modern apps will run, and Google Play Services support is limited.
Trust & buying notes
If you're cross-checking a phone advertised as a kddi KYF31, the fields most worth verifying are: Build.MANUFACTURER lowercase-equal to "kyocera"; Build.SOC_MODEL set (Android 12+) and consistent with Snapdragon 210. For an automated check, run our Hardware Trust Score from the DevCheck AI app and compare its output against this entry.
Because this entry runs Android 5.1, treat it as a reference for older inventory: refurb shops sometimes flash old firmware to make a device look "stock," so a modern build date with this API level is a red flag.
