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 pax Z4 reports its platform as sl8541e_1h10_go. The CPU configuration is 4-core, Cortex-A53, running up to 768 - 1400 MHz. The GPU is ARM Mali-T820 MP1. 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 800x480.
This record reflects Android API level 27 (8.1). Android 8–9 — legacy; many banking and DRM apps drop support at this level.
Trust & buying notes
Because this entry runs Android 8.1, 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.
