Other phones may or may not work for pass-through charging on G8 Galileo.

For Android users, enable the mapping function in the game list of the GameSir World app by following the G-Touch tutorial shown in the screenshot: https://cdn.shopify.com/s/files/1/2241/8433/files/425a96df4bff7114defc1670fd28eb2b.png?v=1739350140

Once mapping is enabled, launch your game through the app. An in-game floating controller icon will appear on the screen: https://cdn.shopify.com/s/files/1/2241/8433/files/92293cb8ae788980fcb6b0e048f236b1.png?v=1739350148

If you encounter issues activating V-Touch mode, refer to the official tutorial video: https://www.youtube.com/watch?v=vqP2za4QfUY

Notes: Touch Mapping functions (G-Touch / V-Touch) are unavailable on iOS devices including iPhone and iPad due to system restrictions. However, most natively controller-supported iOS titles such as Genshin Impact support plug-and-play without extra mapping activation. Compared with Android, iOS features broader native controller compatibility across most mobile games.

This issue occurs because AssistiveTouch is enabled on your iPhone.

1. Tap the Settings icon on the iPhone home screen to open the Settings menu.
2. Tap General, then select Accessibility.
3. Tap AssistiveTouch.
4. Toggle the switch from On to Off to disable the AssistiveTouch feature.

The GameSir G8 and X5 Lite are not supported within the GameSir app on iOS. The controllers will not be detected in the app, and mapping functions as well as game library features cannot be used on iOS devices. Apple restricted controller mapping starting with iOS 13.4, making these features unavailable to iOS users.

You can still play titles with native controller support on iOS. iOS offers broad native compatibility for many games including Genshin Impact. The G8 and X5 Lite support plug-and-play operation for compatible games.

1. Confirm that the OTG function is enabled in your phone settings (common for Xiaomi, OPPO, VIVO, Realme and iQOO devices).

2. Try adjusting the connection sequence of the charging cable and the controller.

3. Use a charger compliant with the standard PD protocol (maximum 9 V / 3 A) or replace your cable.

4. If none of the above steps resolve the issue, incompatibility with the PD protocol is highly probable.

The controller supports a maximum input of 9 V / 3 A. Many mainstream mobile phones support pass-through charging.

Since the charger supplies power to the phone via the controller, both the phone and charger must support PD 2.0 or newer. The controller can negotiate a maximum power profile of 9 V / 3 A with the charger and phone. The actual charging power delivered to the phone is subject to the restrictions imposed by the phone’s system.

Please complete the following three troubleshooting steps:

1. Confirm the connector is fully inserted. Remove the phone case if installed.
2. Verify the OTG function is enabled in your phone settings (common for Xiaomi, OPPO, VIVO, Realme and iQOO devices).
3. Ensure USB Debugging is enabled on your phone.

If the issue persists after completing all steps above, test the controller on another phone to identify the root cause.

Hold the M button + Menu (+) button for 5 seconds to turn off or dim the lighting.

Hold the View + Menu buttons simultaneously for more than 2 seconds until the indicator light changes to another lighting state. The specific color varies by controller model; refer to the user manual for details.

If you are using a Gmail account for login, try switching to an alternative email address if available.

Important reminder: An account is only required for cloud backup of screen mappings. Login is not mandatory if you encounter persistent login difficulties.

If you cannot activate screen touch and controller input simultaneously, confirm that you are using V-Touch Mode and turn on Intensive Mapping.

1. Tap the floating red GameSir icon on your screen.
2. Go to Settings > General Settings.
3. Enable Intensive Mapping.

HID Mode (the foundation of G-Touch) has inherent limitations imposed by its connection protocol. As a result, its performance is marginally inferior to other modes, and this behavior is normal. If this leads to in-game issues, we recommend switching to V-Touch mapping enabled.

For iPhone and iOS users: Apple restricted custom mapping features starting from iOS 13.4. Accordingly, the game library and mapping functions are no longer supported. When gaming on iOS, pair the controller following the recommended procedure and launch your game directly without opening the GameSir app. The GameSir app can still be used solely for firmware updates and controller configuration adjustments.

To roll back firmware: Click the Other Version link on the firmware update page and select the previous stable firmware version.

Detailed operation path within the GameSir app:

1. On the main page, tap the controller icon.
2. Go to Firmware Upgrade > Other Version.
3. Choose your target firmware version.

iOS imposes specific compatibility requirements. Controllers require either an MFi license or Bluetooth connectivity to achieve full functionality. Most GameSir controllers do not carry MFi certification and therefore lack full access under iOS. The X3 Pro serves as an exception. As a premium model, it supports Bluetooth connection to enable complete compatibility with iOS.

Enable Pro Controller Wired Communication following the steps below:

1. Open System Settings from the HOME Menu
2. Navigate to Controllers and Sensors
3. Select Pro Controller Wired Communication
4. Toggle the option to On

G-Touch Technology

G-Touch supports mapping configuration without persistent auxiliary apps. You can connect and play mobile games directly after setup!

Connecting gaming peripherals to smart devices often involves complicated operations due to system limitations, resulting in poor user experience. GameSir has continuously developed and upgraded technologies to resolve such troubles. You can understand G-Touch as follows: G-Touch direct-connect technology simulates a virtual touch peripheral on your phone or tablet. Commands sent by the GameSir controller are identified as native system input signals, which means all controller operations act as direct screen touches.

Controller operation = physical touch operation (no overlay mapping)

In this mode, the GameSir controller runs in an invisible state on the device. The advantages are listed below:

1. No additional downloads required
2. No activation steps
3. No secondary applications needed
4. No jailbreak or root access required
5. No cloud adaptation packages, and more

G-Touch direct-connect technology works with Android devices for the following controllers released after 2023: G8 Galileo / G8+, X3 Pro, X2 Bluetooth / Type-C, X2s Bluetooth / Type-C, G4 PRO Wireless Controller, and more.

Notes: Apple blocks third-party mapping functions. Therefore, G-Touch cannot be used on iPhones and iPads. iOS devices only support games with native controller support. If you need controller compatibility for a game, please reach out to the game developer.

G-Touch vs V-Touch Explanation In short, G-Touch directly transmits touch signals to the screen. When mapped, it behaves identically to physical finger contact. V-Touch is a system-level virtual simulation of screen touches.

We recommend using G-Touch whenever available for broader game compatibility.

No worries, all GameSir controllers are equipped with overcharging protection, whether used with a charging dock or not. Charging will automatically stop once the controller reaches full battery. Normally, the indicator light turns off upon full charge.

1. Connect your phone to the controller. Hold the View button + Menu button + Home button for 2 seconds. The Home indicator and Mode indicator will flash white slowly, confirming the controller has entered calibration mode.

2. Complete calibration within the mode following these steps: a) Rotate both joysticks fully to their maximum range three times, then let them return to the center position naturally. b) Pull both triggers all the way to maximum travel three times, then release them to return to the original position naturally.

3. Press the A button to save settings and exit calibration mode.

Notes:

1. Operate gently with steady speed during calibration to prevent inaccurate data sampling.
2. Calibration is unnecessary if the joysticks and triggers function normally.
