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 samsung SM-G998B reports its platform as Exynos 9825. The CPU configuration is 8-core, Mongoose-M4 Cortex-A75 Cortex-A55, running up to 442 - 2730 MHz. The GPU is ARM Mali-G76 MP12. 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
12 GB LPDDR4X of RAM is ample for any current workload, including multitasking-heavy use and on-device AI. Display resolution is 3040x1440.
This record reflects Android API level 34 (14). Android 14 or newer — modern security baseline, supported by all current banking and payment apps.
Trust & buying notes
For a second-hand purchase, also verify the security patch date is no more than ~12 months old, the boot count is plausible for the claimed age, and battery health is above 85%.
