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 AST21 reports its platform as mofd_v0. The CPU configuration is 4-core, Family 6 Model 90 Stepping 0, running up to 500 - 2333 MHz. The GPU is Imagination Technologies PowerVR Rogue Hood. Without a confirmed SoC tier mapping for this platform string, we treat the device as unverified. If you're using this entry to compare against a phone you're inspecting, focus on the raw fields below rather than tier-level conclusions.
Day-to-day workload
2 GB of RAM is below the realistic minimum for current Android — expect Android to aggressively kill background apps. Display resolution is 1920x1200.
This record reflects Android API level 19 (4.4). Android 7 or older — effectively retired; very few modern apps will run, and Google Play Services support is limited.
Trust & buying notes
Because this entry runs Android 4.4, 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.
