Buyer feedback ↓The original gray GameSir G8 Galileo connects directly to a compatible USB-C phone. Full-size sticks, curved grips and two rear buttons make it feel closer to a console controller; the phone is separate.

THE QUICK TAKE
Is it right for you?
Choose it if small phone-controller grips cramp your hands. The large handles and full-size sticks give you more to hold during longer sessions. Direct USB-C connection also avoids pairing and a separate controller battery.
Skip it if pocketable size matters more than comfort. This is a broad controller, and a thick phone case may need to come off. Check your phone’s fit and the game’s controller support; a USB-C connector alone does not guarantee that every game will work.
01 / BUYING NOTES
Before you buy.
Check the phone and its case.
The phone sits between the grips and plugs into the right side. A thick case or camera bump can prevent a good fit, even when the phone has USB-C.
Charging and headphones have their own ports.
The bottom edge has a charging input and wired headphone jack. Pass-through charging depends on the phone; the controller does not add a battery of its own.
Use the stick shape that suits your hands.
The magnetic faceplates lift away to reach the sticks. Different included stick caps change the feel; the Hall-effect sensors are inside the controller.

02 / AMAZON REVIEWS
The buyers’ view.
Buyers praise the console-like grips and controls, though one large-handed owner still found the layout cramped. Case fit varies: one owner used a thin case, while another had to remove a Quad Lock case.
App experiences range from useful mapping to awkward controls and failed calibration. One owner accidentally hit buttons below the D-pad during fast play; another reported pass-through charging failure after extended use, despite the remaining controls holding up.

The reviewer found the large grips comfortable and the controls well suited to first-person games. The directional pad felt less crisp for a demanding platform game, and phone-case fit still needed checking.
GameSir lists Hall-effect sticks, interchangeable caps and rear controls. These features belong to the original wired G8; the Bluetooth G8 Plus is a different controller.
