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 yepen X12 (K12) Pro Max reports its platform as ums312_2h10. The CPU configuration is 4-core, Cortex-A75 Cortex-A55, running up to 614 - 2002 MHz. The GPU is Imagination Technologies PowerVR Rogue GE8300. 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

4 GB of RAM is tight for 2026 standards — usable for the basics but limits modern app behavior. Display resolution is 1560x720.

This record reflects Android API level 28 (9). Android 8–9 — legacy; many banking and DRM apps drop support at this level.

Trust & buying notes

Because this entry runs Android 9, 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.
