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-G991B reports its platform as exynos2100. The CPU configuration is 8-core, Cortex-X1 Cortex-A78 Cortex-A55, running up to 400 - 2912 MHz. The GPU is ARM Mali-G78. 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

8 GB of RAM is comfortable for modern apps and moderate multitasking. Display resolution is 2400x1080.

This record reflects Android API level 30 (11). Android 10–11 — increasingly limited; expect some modern apps to refuse to install or downgrade features.

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%.
