Not all gamers have to throw hard-earned cash at fancy handheld gaming units like the Steam Deck. If you game via options like Game Pass that can stream from your phone and you just so happen to have a fancy flagship smartphone in your pocket, why not just use that? This is where options like the GameSir G8 Galileo Mobile Gaming Controller enter the scene.
These controllers have been around for a while now but they just keep getting better each year. With the new G8 Galileo, you gain some added features that bring it up to speed with the common trends in gaming. Trends like the Hall Effect sticks and triggers, customizable parts, and mappable buttons.
GameSir has been around since 2013 developing both console and mobile controllers. For ten years, it has been focused on the gaming community and it shows in its attention to detail. Everything comes to you well-protected during shipment, features a sturdy build quality to everything, and even comes with swappable sticks so you can really get the fit that works best for your thumbs.
This new controller comes with a USB-C connection, making it compatible with most modern phones, including the new iPhone 15 models that have finally moved away from the Lightning connection. Not to mention every Android phone that has come out since the world stopped using micro USB (for smartphones, at least).
It offers the XYBA Xbox-style layout of buttons, naturally placed sticks, and everything else you’d find on an Xbox controller. Including the four triggers/buttons up top.
In addition to this, you have capture and mode buttons (bottom-left). The first is self-explanatory and the second functions as a go-to for customizing every button on the controller. Using this button in conjunction with other buttons, you can enable/disable hair triggers, turbo function, or even swap the A->B and X->Y buttons.
All of your buttons are mappable to the two extra buttons on the back. These buttons can take on anything you want, including the capture button, menu, or even the D-pad. So if you find it easier to make use of these so your right thumb never has to leave the stick, you have this option.
The faceplates both on the left and right side easily pop off and re-attach using magnets. So you don’t have to unscrew anything to swap out those sticks and you can customize the controller with difference faceplates and switch back and forth.
What’s nice is that the faceplates attach so well that no one would know they even come off unless you told them. They snap flush to the rest of the controller as if they were screwed into place. Offering a natural look without any added bulk.
The only catch is there aren’t any custom faceplates available just yet. But I’m sure those are just around the corner.
The bottom of the controller features a 3.5mm headphone jack. Something that is quite valuable for smartphones that no longer have one. Next to it is a USB-C port that comes in handy for long gaming periods.
With the USB-C port, you can plug into a nearby outlet adapter using pass-through charging. Keeping your phone juiced while you get your game on. This is because this controller uses your phone to power itself. So if you play long enough, you will see the battery of your phone begin to drop over time.
There is no internal battery inside the controller itself. It either gets power from your phone or from a wall outlet (which also charged the phone).
The controller slides open to accommodate anything between 110 and 185 mm in length. This should be enough for just about any modern or semi-modern phone out there that features a normal candybar style design (so no fancy folding phones). The only other exception would be models that have bulk camera lens protruding out the back too far (this only includes a few models for the most part). The phone has to be 13mm thick or less to fit and the camera lens can’t extend past 5mm.
Also, the fact that it is USB-C means that it is future proofed for the time being. As any phone should be launching with USB-C since it is a universal standard now. Even if that USB-C port becomes Thunderbolt compatible in future models.
It doesn’t just excel at durability. Performance is fantastic since you don’t have to charge it. It is 100% plug-and-play, beginning to function the moment you slide your phone into place. We have used it against 6 different models thus far and it has delivered with every experience.
At first, no app is needed. You can get right into something like the Xbox Game Pass app and start playing your favorite games. However, downloading the GameSir app will allow you to customize the controller fully. So it is smart to give that an install.
The custom features of the controller are great and can give you a little bit of an edge in your games. The sticks feel natural and solid in your hands and so do all of the buttons. It feels like you have a normal controller in your hands outside of the fact that your hands are further apart.
If you are a gamer, you’d likely enjoy using this controller. If you enjoy playing games on the go, you would very likely enjoy using this controller. If you are also an Xbox fan controller-wise, you will absolutely love using this controller.
This model is solid in both construction and function. Its customization capabilities, swappable faceplates, vast compatibility to smartphone models, pass-through charging, Hall Effect triggers/switches, and audio jack. In fact, we absolutely loved everything about it except for one minor detail (safely storing it during travel).
It doesn’t fold down or anything so it can be a little cumbersome to lug around. So if you don’t have a bag of some sort to drop it in, you likely won’t be dragging it with you everywhere. It could also benefit from having a form-fitting semi-hardshell carrying solution (case). That could be kept to a minimal footprint if form-fitting to the shape of everything across the front (sticks and all). Allowing shipped materials to remain minimal as well as space used up in your bag.
The only thing else it is missing is haptic feedback, but that is reasonable. You can only imagine the battery drain on your phone, not to mention a thick and heavier profile of the controller. So this doesn’t weigh heavily on the score in any way. We are just good at finding what’s missing from any product (aka, critics).
