AliexpressThe GameSir G8 Galileo USB-C Mobile Controller is designed for playing compatible mobile games with a dedicated gamepad rather than relying only on touchscreen controls. This selected option is the original G8 Galileo controller in the G8 option, not the G8 Plus Bluetooth model and not a case or accessory option. It connects directly to supported phones through USB-C and does not use a built-in battery.
Compatibility and connection
GameSir documents support for selected Android phones and the iPhone 15 series. The iPhone 15 claim should not be extended to every USB-C iPhone. Game and mode support can also vary, so confirm that the titles you use recognize a gamepad before ordering.
- Direct USB-C connection to supported Android phones.
- Direct USB-C connection to the iPhone 15 series.
- Original G8 Galileo model, distinct from G8 Plus Bluetooth.
- No controller battery is required for the wired connection.
Fit and everyday use
The manufacturer specifies a caseless phone length range of 110–185 mm, with phone depth up to 13 mm and camera depth up to 5 mm. These measurements are useful starting checks, but they do not guarantee that every phone will fit or that every phone-and-charger combination will support pass-through charging. Remove or account for a phone case when comparing dimensions.

Important limitations and buying checks
Compatibility is not universal across USB-C phones. Before purchase, check your exact phone model, its case dimensions, camera clearance, and whether your games support a controller. If you need pass-through charging, verify the phone, charger, and protocol combination separately rather than assuming it will work.
GameSir support flags firmware V130 as buggy and directs affected users to V129. Follow the current instructions for the exact G8 Galileo model; this page is not a firmware test. The phone and any case are not included, and optional accessories should not be assumed to form part of the selected package.
