Android 8.1 GO is a lightweight version of Android designed for devices with 1GB of RAM or less. If your unit has 1GB RAM, you are stuck with GO. However, many sellers spoof their specs. A unit claiming "Android 10" but showing "8.1GO" in the engineer menu is common. Do not trust the settings menu; trust the chipset.
