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 android S21 Ultra is built around the MT6580, a budget SoC from MediaTek. It launched in 2015 on a TSMC 28nm process. Ultra-budget 3G SoC of the mid-2010s; in countless white-label Android phones.
Legacy. Not realistically usable as a primary phone in 2026.
Day-to-day workload
1 GB LPDDR3_1066 of RAM is insufficient for modern Android. Display resolution is 1014x480.
This record reflects Android API level 23 (6.0). Android 7 or older — effectively retired; very few modern apps will run, and Google Play Services support is limited.
Trust & buying notes
If you're cross-checking a phone advertised as a android S21 Ultra, the fields most worth verifying are: Build.MANUFACTURER lowercase-equal to "android"; Build.SOC_MODEL set (Android 12+) and consistent with MT6580. 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 6.0, 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.
