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 docomo SO-51A is built around the Snapdragon 865, a current or recent flagship-tier SoC from Qualcomm. It launched in 2019 on a TSMC 7nm N7P process. The 2020 flagship; widely deployed in Galaxy S20, OnePlus 8, and Xiaomi Mi 10 series.
Holds up well in 2026 for daily use and most gaming. Pairs with LPDDR5 and UFS 3.0 on most launch devices.
Day-to-day workload
8 GB LPDDR5 of RAM is comfortable for modern apps and moderate multitasking. Display resolution is 3840x1644.
This record reflects Android API level 31 (12). Android 12 — at the edge of current support; most apps still work but some new features may not be available.
Trust & buying notes
If you're cross-checking a phone advertised as a docomo SO-51A, the fields most worth verifying are: Build.MANUFACTURER lowercase-equal to "sony"; Build.SOC_MODEL set (Android 12+) and consistent with Snapdragon 865. For an automated check, run our Hardware Trust Score from the DevCheck AI app and compare its output against this entry.
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%.
