GameHub not working: quick fix table

Find your problem in the table, try the quick fix, and jump to the matching section if it does not help. Always update GameHub first, because many bugs are fixed in newer versions.

How to fix GameHub network error

A GameHub network error is usually caused by your internet connection, a VPN or region issue, or a temporary server problem. Check your connection first, then your VPN, then update the app.

1. Test your connection. Open a website in your browser. Switch between Wi-Fi and mobile data, or restart your router.
2. Check your VPN and region. If you use a VPN, turn it off and try again. GameHub's Google Play listing is not available in every country, so some services may behave differently by region. Trying another network can help.
3. Check the server status. Look at the official GameHub Discord or the in-app community (added in 6.3.1). If many users report the same error, it is a server problem – wait and try later.
4. Set date and time to automatic. A wrong clock can break secure connections.
5. Clear the app cache. Go to Android Settings, then Apps, GameHub, Storage, and tap Clear cache. Avoid "Clear data" unless nothing else works, because it resets the app and may remove settings and downloaded data.
6. Update GameHub. Install the latest version from Google Play or the official GameHub website.

How to fix "App not installed" error

"App not installed" means Android blocked the install. The usual causes are a signature conflict with another GameHub build, low storage, an Android version older than 10, or a broken download.

Signature conflict with GameHub Lite or an old build

Android only installs an APK over an existing app if both are signed by the same developer. If you have GameHub Lite, a modded build or an APK from a mirror site installed under the same package name, uninstall it first. Before you do, make sure your progress is saved with Steam cloud saves.

Not enough storage

The GameHub APK is about 95 MB, but the app also loads extra components such as drivers after install. Free up space, then try again.

Android older than version 10

GameHub 6.3.1 requires Android 10 or newer, so it will not install on older phones. Open-source alternatives Winlator and GameNative support Android 8 and newer; see our GameHub vs GameNative vs Winlator comparison.

Corrupted or incomplete download

Delete the APK file and download it again from an official source. Our GameHub download page lists Google Play and the official website. If Google Play Protect warns you about a file from an unknown site, do not install it.

How to fix GameHub black screen

A GameHub black screen is most often caused by a GPU driver and DXVK version that do not match. Try a different Turnip driver or DXVK version, and lower the resolution to 720p.

1. Wait a little on first launch. A game's first start can take longer. Give it a minute before you close it.
2. Lower the resolution. Set 720p in the game's settings page.
3. Try another Turnip driver (Snapdragon). Community packs by GPU: Adreno 8xx – StevenMXZ / whitebelyash builds; Adreno 7xx – Mr Purple T25/T26; Adreno 6xx – K11MCH1 R5.
4. Change the DXVK or VKD3D version. DXVK handles DirectX 9–11 games and VKD3D handles DirectX 12. Keep the driver and DXVK versions matched.
5. On Mali phones, update and use the bundled drivers. Turnip only works on Adreno GPUs. Version 6.0.6 also fixed frame interpolation on Mali.
6. Reset the game's settings. If you changed many settings, go back to the defaults and change one thing at a time.

How to fix GameHub game crash and stutter

Crashes and stutter usually come from low RAM, too many background apps, an overheating phone, or a game that is not compatible yet. Free up memory, cap your FPS and try a stability preset.

• Close background apps. Reviewers recommend 8–12 GB of RAM for GameHub, and every open app takes some of it.
• Cool the phone down. Hot phones slow down and can crash. Cap FPS, remove thick cases and avoid charging while you play.
• Try a stability preset. If your version offers Box64 presets, a stability preset can stop crashes at the cost of some FPS.
• Lower graphics. Use 720p, FSR 3 and lower in-game settings.
• Check compatibility. Look at the game's rating in GameHub (revamped in 6.0.6) and community reports on our GameHub compatibility list.
• Keep free storage. A nearly full phone can cause crashes and failed loads.
• Expect some early stutter. Short stutters when you enter a new area are common with translation layers and often get better as you keep playing.

How to fix GameHub login and Steam login problems

If you cannot log in to Steam in GameHub, check your internet, try the other sign-in method (QR code or username and password), and approve the login in the Steam mobile app. For GameHub account problems, update the app and clear its cache.

1. Use the right place. Steam is linked from your Profile in GameHub (link account).
2. Switch the sign-in method. If the QR code fails, use your username and password, and the other way round.
3. Approve the login. Steam may ask you to confirm the sign-in in the Steam mobile app or enter a code.
4. Check network, date and time. The same fixes as for a network error apply here.
5. Update GameHub. Version 6.2.0 fixed component loading and cloud-save sync problems, so always use the latest version.
6. Check your app version. The Google Play version supports Steam only. Epic Games, GOG and EA accounts need the website version.

Controller not detected in GameHub

If GameHub does not detect your controller, pair it again in Android's Bluetooth settings (or reconnect the USB cable), restart GameHub and check the controller mapping in the app.

1. Connect at system level first. Pair the controller in Android's Bluetooth settings, or plug it in by USB.
2. Restart GameHub. Open the app after the controller is connected.
3. Check the controller mode. Many controllers have different modes. Use the mode your controller's manual recommends for Android.
4. Check mapping. Version 6.0.6 added gamepad-to-keyboard and gamepad-to-mouse mapping and a new virtual button layout editor. Version 6.2.0 added key and mouse mapping with cloud sharing. Use these if a PC game expects a keyboard.
5. Test another game. If only one game ignores the controller, check that game's own input settings.

When to contact GameSir support or Discord

Contact GameSir through the official GameHub Discord or the in-app community if a problem remains after these fixes, or if many users report the same error. Clear details get faster help.

Include this information in your report:

• Phone model, chip and Android version
• GameHub version (for example 6.3.1) and where you installed it from
• Game name and store (Steam, Epic, GOG or EA)
• Your driver, DXVK version and resolution
• A screenshot or short video of the error

GameHub Lite and AnTuTu builds are not made by GameSir, so report their problems on the GameHub Lite GitHub page instead. If a new update breaks a game you play, some users go back to an older build; see our GameHub old versions page for the version history.

Bottom line

When GameHub is not working, start simple: check your internet, update to the latest version and free up storage. Black screens are usually a driver and DXVK mismatch, crashes are usually RAM or heat, and "App not installed" is usually a conflict with another build. If nothing helps, get a clean copy of the GameHub APK from an official source and ask on the official Discord.
