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The docomo SO-04J is built around the Snapdragon 835, a legacy flagship — capable in its day, now superseded from Qualcomm. It launched in 2016 on a Samsung 10nm 10LPE process. 2017 flagship (Galaxy S8, Pixel 2). Largely retired from active support in 2026.
Suitable only as a secondary or backup device. Most modern apps still install but many newer titles drop support.
Day-to-day workload
4 GB LPDDR4X of RAM is tight for 2026 standards — usable for the basics but limits modern app behavior. Display resolution is 3840x2160.
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
If you're cross-checking a phone advertised as a docomo SO-04J, the fields most worth verifying are: Build.MANUFACTURER lowercase-equal to "sony"; Build.SOC_MODEL set (Android 12+) and consistent with Snapdragon 835. For an automated check, run our Hardware Trust Score from the DevCheck AI app and compare its output against this entry.
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.
