We have already prepared GameSir X4 Aileron in our analysis table to show each of its details. In fact, it looks like a controller to take for a trip and we can tell you to play for two people at the same time. So stay till the end and join us to find out!
GameSir X4 Aileron: A two-piece Bluetooth controller packed with amazing features

The GameSir X4 Aileron is a two-piece controller that connects to an Android mobile via Bluetooth. It has many advanced technologies and features, but let’s take it step by step. See the technical paper to review each feature.
What does the GameSir X4 Aileron controller look like?
GameSir X4 Aileron has high-end build quality. After all, it’s an officially licensed Xbox controller. It is made of matte black plastic and molded rubber pads on the handles to prevent slipping.
It’s not the most ergonomic mobile controller I’ve ever seen in my hands (the GameSir G8 Galileo still holds the throne), but it’s very comfortable and I was able to use it for several hours without fatigue in my hands. Of course, as far as mileage goes, it seems to me to be one of the best options available at the moment.
And GameSir Rigid (included in the box) well protected. In addition, this type of two-part design allows the controller to fit any mobile phone, regardless of its length.
As long as your phone has Android 8 or higher, with a width between 68 and 95mm and a thickness of no more than 12.5mm, you can use the GameSir X4 Aileron controller. Another advantage of this design is that the two parts of the controller are not physically connected, leaving the back of the mobile phone free, so you can connect a wireless charger (magnetic) or a fan. Does it have any disadvantages? Yes, it’s not as stable as other controllers, although I didn’t experience any issues or irritations while playing.
Another “flaw” I’ve found is that phones with camera modules like the Nubia Z60 Pro Ultra can have problems.
Smart power on and off
Each remote control unit has a green clip that holds the mobile firmly in place. The amazing thing about these clamps is that when they are turned on, the control automatically turns on. And when you download it, the control turns off because it knows you haven’t used it. It’s a simple idea, but it’s very useful to prevent the remote control from turning on and thus save battery.
Is it possible to turn it on without removing the clamps? Yes, you can use it as a standard Bluetooth controller. To do this you will need to force the ignition as described in the GameSir X4 Aileron User Manual.
You can customize the buttons, levers and crosses as you like.
As for the buttons, use the official Xbox controller layout. That is, it has two asymmetric levers, ABXY buttons, menu button, view button, RB, LB, RT, LT back buttons, share button, Xbox button and a directional pad or joystick.
It also has two buttons on the back that allow you to change the effect and brightness of the RGB lights on the joystick, as well as two buttons that allow you to change the shooting modes and the order of the ABXY buttons.
It should be noted that the box includes two pairs of additional levers of different sizes that can be easily installed by lifting the installed rods. You have to pull a little until they come out.
It comes with a different design with an additional directional control, so if you don’t like what it comes with, you can save it. The ABXY buttons can also be removed to sort as you wish. You can put a Nintendo design on it if you want!
How does GameSir X4 Aileron work?
As we mentioned at the beginning, GameSir X4 Aileron connects to your mobile via Bluetooth. To pair it, pair both parts of the controller with the mobile and then press and hold the Bluetooth button for 2 seconds. Then simply turn on your phone’s Bluetooth and select the controller from the list of nearby devices. Once connected, you can start playing with compatible games or customize it with the GameSir app.
The process is flawless. All buttons respond quickly and do not take much to press. It is worth noting that the lifts have a Hall effect, which means that they do not have sliding problems (irregular movements). In addition, they have anti-collision sliding rings, which provide smooth control.

The triggers are unique because they offer dual operation: you can use them in analog mode (ideal for competitive games where you need to distinguish different speed levels) or in “hair trigger” mode (great use in FPS games, for example). , because it recognizes the printer with a slight touch without delay).
Although the connection between the controller and the mobile phone is via Bluetooth, we didn’t notice any lag while playing. When playing with cloud game services (Game Pass and GOCF Now), we don’t experience lag or high lag that affects the experience.
It is compatible with mobile games that do not support controllers
By the way, this controller has a function called “V-Touch” to map and make it compatible even with games that don’t support controllers. This feature is a little difficult to use at first (the video below explains how it works), but after you set it up for the first time, the rest is a piece of cake.
Only one part of the controller can be used
Another detail that impressed me about this controller is that you can use a single unit separately (the left one with the hanger). Each part of the controller can be used separately so that two people can play on the mobile at the same time. Yes, just like the Switch Joy-Con.
And as for the autonomy, the 400 mAh lithium battery in each part of the controller will last for a long time. I’ve been using it for over three days and haven’t had to charge it yet. Incidentally, it charges through the USB-C port.
Is the GameSir X4 Aileron Controller worth it?

The GameSir X4 Aileron is without a doubt the most versatile mobile controller I’ve had the chance to test. “Joy-Con” has become a reality for Android enthusiasts.
Durable, with interchangeable pickups, pads and keys, its compact design makes it easy to travel with, is responsive, has minimal lag, and can be played individually or with the two units separated for two people. It is very complete! If we have to criticize, the mapping is a bit complicated as it is not compatible with mobile phones with large camera modules.
