Start with the message on screen
Do not begin by reinstalling or changing developer settings. The message tells you whether the problem belongs to the store, account region, device, package installer, storage, or the game after installation. Take a screenshot before dismissing it, especially when the message includes an error code.
- Check countries and storefront availability — Separate a regional restriction from an installation fault.
- Check minimum requirements and download size — Android, iOS, storage, RAM, chipset, and compatibility boundaries.
| Message or symptom | Most likely checkpoint | First action |
|---|---|---|
| The app is not available in your country or region | Storefront country or regional rollout | Check the account country against the available-country list |
| This device is not compatible | Operating system or store device profile | Confirm Android 7.0 or iOS 13.0, then trust the store result for that device |
| Download pending or stuck | Connection, store queue, date/time, or store cache | Stop other downloads, verify the connection, and restart the store |
| Not enough storage | Download, extraction, and first-launch space | Free space beyond the number shown on the store page |
| App not installed | Package conflict, incomplete file, or installer restriction | Verify the source and package ID before changing permissions |
| Unable to verify app or billing problem | Apple Account, payment, age, or storefront state | Resolve the exact App Store account prompt |
| Installed but closes or stays black | Update, damaged resources, memory pressure, or service issue | Restart, update the system and game, then test before reinstalling |
Verify the game before changing phone settings
The current Android package is com.levelinfinite.gst and the publisher shown on Google Play is Level Infinite. The current Apple listing uses App Store ID 6472700792. A file with another package identity, a MOD label, unlimited currency, a separate installer, or a password-protected archive is not the verified store build.
- Android: open Google Play from the official game website or use the verified package listing.
- TapTap: use app ID 33754914 and confirm the provider is Level Infinite before downloading.
- iPhone and iPad: use App Store ID 6472700792 in a supported storefront.
- Do not disable Play Protect, system security, or package verification to install a modified or mismatched file.
- Use the official download routes — Open the correct store for Android or iOS.
- Check MOD APK warning signs — Identify altered packages and remove permissions safely.
Fix Google Play download and installation problems
Google recommends beginning with the connection, storage, Android update, Play Store restart, device restart, and automatic date and time. Its support page notes that less than 1 GB of available space can stop apps from downloading or installing; Gangstar Mirage City may need considerably more because the delivered package and first-launch resources are larger.
- Pause other app downloads and switch to a stable Wi-Fi connection or strong mobile data connection.
- Open Settings, then Storage, and free enough space for the download, extraction, and later game resources.
- Open the Android system-update screen and install an available stable update.
- Close Google Play Store completely, reopen it, and retry the game listing.
- Restart the phone, then confirm automatic date, time, and time zone are correct.
- If only this game is unavailable, recheck country and device compatibility instead of repeatedly clearing the store.
- Clear Google Play Store data only after the basic checks; this resets the store app, not Gangstar Mirage City progress.
- Open the Android installation guide — Current package, version, size, and Google Play identity.
- Read Google Play basic troubleshooting — Official Android store steps.
Fix TapTap download or package installation problems
TapTap can show a game page even when the Android package installer later rejects the download. Update TapTap first, delete the incomplete game download inside TapTap, and download it again. If Android asks for permission to install unknown apps, grant it only to the TapTap app being used and remove that permission after installation. Menu names vary by Android version and manufacturer.
- Open the TapTap download guide — App ID, provider, package checks, and the Xiaomi workaround.
| TapTap symptom | What to check | What not to do |
|---|---|---|
| Download restarts or checksum fails | Update TapTap, use a stable connection, remove the partial download, and retry | Do not reuse an incomplete APK or split-package set |
| Install button returns to the listing | Check free space and the Android package-installer prompt | Do not keep tapping Install without reading the prompt |
| Install unknown apps is blocked | Open the app-specific permission for TapTap only | Do not enable unknown-app installation for every browser and file manager |
| Package conflicts with an existing app | Confirm whether an old test or modified build uses the same package ID | Do not uninstall before confirming account progress is synced |
| The installed package name is unexpected | Stop and remove the unexpected package | Do not sign in or grant accessibility, VPN, or device-admin access |
Xiaomi and Redmi: MIUI cannot install the TapTap package
TapTap Official documents a MIUI-specific workaround for games that still fail to install after TapTap is updated and the package is downloaded again. This is a last installation step, not a performance tweak. Disabling MIUI optimization can change permission behavior, battery management, performance, and parts of the interface. Turn it back on after the installation attempt.
- Update TapTap to the latest available version, remove the failed game download, and download Gangstar Mirage City again.
- Enable Developer options. On many MIUI versions, open Settings, About phone, and tap MIUI version repeatedly until the developer message appears.
- On MIUI 13 and later, TapTap describes the path as Settings, My device, Detailed info and specs, then repeatedly tap MIUI version.
- Open Settings, Additional settings, Developer options, then turn off Turn on MIUI optimization.
- Return to TapTap and run the installation again.
- After the installation attempt, return to Developer options and turn MIUI optimization back on.
- If the switch is absent on HyperOS or the menu differs, do not use hidden commands to force it. Use the official Google Play route or ask TapTap/Xiaomi support about that exact system build.
- Read the TapTap MIUI instructions — TapTap Official also describes the side effects and recommends restoring optimization.
Samsung Galaxy: Play Store is stuck or will not update
Samsung advises checking the network and restarting the Galaxy device before resetting store components. One UI menu labels can differ by Android version. Clearing Google Play Store data may require the Google account to initialize the store again, so make sure the account login method is available first.
- Confirm Wi-Fi or mobile data actually reaches the internet; an exclamation mark beside Wi-Fi indicates a connection problem.
- Restart the Galaxy phone or tablet, then open the Gangstar Mirage City listing again.
- Open Settings, Apps, Google Play Store, Storage, then clear Play Store data if downloads still do not start.
- Open Settings, Apps, Google Play Services, Storage, then clear its cache if the store remains stuck.
- Check Download Manager and automatic date/time if every Play Store download fails.
- If only Gangstar Mirage City is rejected, check regional availability and device compatibility rather than resetting the entire phone.
- Read Samsung Play Store troubleshooting — Official Samsung steps; menus vary by Galaxy model and Android version.
Huawei phones: choose the store route before troubleshooting
Huawei phones differ by model, region, and software build. Some include Google Play services and some use Huawei Mobile Services without Google Play. If Google Play is already supported on the device, use the normal Android checks. If it is not present, do not install unofficial Google service packages merely to obtain this game.
- Search AppGallery for the exact game title and verify the publisher before installing; a similarly named listing is not enough.
- If no verified AppGallery listing is available, open the current TapTap listing and confirm app ID 33754914, Level Infinite, and package com.levelinfinite.gst.
- When EMUI requests permission to install from another source, grant it only to the selected store app and remove it afterward.
- Do not disable system-wide scanning or grant Accessibility, Device Administrator, VPN, or account permissions to a separate installer.
- A successful installation does not guarantee Google-dependent login, payments, notifications, or update delivery on a device without Google services.
- If the game launches but sign-in or purchasing fails, record the Huawei model, EMUI/HarmonyOS version, store source, login method, and exact message for publisher support.
- Learn about Huawei AppGallery — Huawei store information; game availability still depends on region and listing.
iPhone and iPad: App Store download or update fails
The App Store build requires iOS or iPadOS 13.0 or later and a supported Apple storefront. Apple recommends resolving the account prompt, prioritizing the download, and restarting before seeking support. A valid payment method may be required even when the app itself is free.
- Open the verified App Store ID 6472700792 and check whether the page says unavailable in the current country.
- Check Settings, General, iPhone Storage and free space for the listed package plus installation and first-launch resources.
- If the icon is waiting, touch and hold it on the Home Screen and choose Prioritize Download.
- Resolve any billing problem, verification-required message, payment-method prompt, or age-confirmation request shown by Apple.
- Restart the iPhone or iPad and retry the App Store download or update.
- Do not install a configuration profile or enterprise certificate offered as a regional bypass.
- If the same Apple prompt remains, contact Apple Support; if the game installs but cannot connect, check the game service and publisher support.
- Open the iPhone and iPad download guide — App Store ID, package size, minimum iOS, and availability.
- Read Apple download troubleshooting — Official App Store steps.
An update fails but the game is already installed
Protect account access before uninstalling. An update problem can come from the store, storage, regional account, package source, or a version mismatch, while uninstalling can remove local files. Confirm that progress is linked to the intended game or platform account before removing anything.
- Screenshot the player ID, login method, current version, and error message.
- Update from the same trusted store that installed the current package.
- Free additional space and restart the device before attempting the update again.
- Remove a stuck store download and retry; do not install an older package over a newer build.
- Clear the store cache before considering game data. Clearing game data can remove local settings or unsynced progress.
- Reinstall only after account recovery and progress synchronization are confirmed.
The game installed but will not open
An installation fix cannot resolve every launch problem. Restart the device, install the current stable system update, update the game from the same store, close overlays and screen recorders, and let the phone cool before testing again. If the title screen appears but login fails, treat it as a network, account, or service problem rather than repeating the installer steps.
| Launch symptom | Useful evidence | Next route |
|---|---|---|
| Immediate crash | Device model, OS, RAM, free storage, game version | Update and restart, then compare with background apps closed |
| Black screen | Time on screen, audio state, graphics overlay, temperature | Close overlays, cool the phone, and retry once |
| Resource download loops | Network, free storage, percentage or file shown | Change to a stable connection and confirm storage |
| Login fails | Login method, region, exact server message | Check official service notices and publisher support |
| Runs but stutters or overheats | Graphics preset, route, session duration, charging state | Use the settings and performance guide |
Avoid fixes that create a larger problem
- Do not factory-reset the phone for one game before the store or publisher identifies a device-wide fault.
- Do not change the account country without reviewing subscriptions, balances, payment methods, and regional terms.
- Do not disable MIUI optimization unless the failure is the documented TapTap/MIUI installation case, and restore it afterward.
- Do not disable Play Protect or iOS security to install a modified package.
- Do not clear game data or uninstall until the account and progress recovery path is confirmed.
- Do not post player IDs, account email addresses, receipts, or login codes in public comments.
What to include when asking for help
A complete report helps another player or support agent distinguish a regional block from a device or installer failure. Remove personal account information before sharing a screenshot publicly.
| Field | Example of useful detail |
|---|---|
| Device | Xiaomi Redmi Note model, Samsung Galaxy model, Huawei model, iPhone model |
| System | MIUI/HyperOS, One UI, EMUI/HarmonyOS, iOS/iPadOS and exact version |
| Store | Google Play, TapTap app ID 33754914, AppGallery, or App Store ID 6472700792 |
| Game build | Version shown by the store or installed app |
| Region | Store account country, not a precise address |
| Failure point | Listing unavailable, download, package install, first launch, resources, login, or update |
| Exact message | Screenshot or complete error text with personal details removed |
| Checks completed | Connection, storage, restart, system update, store reset, or MIUI workaround |
Common installation questions
| Question | Answer |
|---|---|
| Why does Gangstar Mirage City say app not installed? | Verify the package source and ID, remove an incomplete download, check storage, and look for an old test or modified build conflict before changing installer permissions. |
| Should Xiaomi or Redmi users disable MIUI optimization? | Only use that TapTap-documented workaround when a TapTap game package still fails after updating TapTap and downloading again. Restore MIUI optimization after the installation attempt. |
| Can I install Gangstar Mirage City on a Huawei phone? | It depends on the exact model, region, software, verified store listing, and the game login dependencies. Use Google Play only when supported, otherwise verify AppGallery or the TapTap listing without installing unofficial Google service packages. |
| Why is the game unavailable on iPhone? | The Apple Account storefront may not be supported, the device may not meet iOS 13, or an account, storage, billing, verification, or age prompt may be blocking the download. |
| Will clearing game data fix installation? | No. Installation happens before game data can help, and clearing data can remove local settings or unsynced progress. Start with the store and installer checks. |
| How much space is required? | The current store download is not the final installed size. Keep additional space for extraction, first-launch resources, caches, and updates. |
