U388 app will not install or keeps closing
Download blocked, install refused, or the app shuts down straight after launch.
Play at U388 →A U388 app that will not install or closes at launch is fixed from the phone: allow the install source on Android, clear the app cache and reinstall if it keeps closing, and on iOS add the site to the home screen from Safari — the shortcut opens the same account and games.
Install and launch problems
- Android install blocked: the file arrives from outside the store, so the phone asks you to allow that source before the install can finish.
- App closes right after the splash screen: clear its cache and reopen, and if it still closes, remove it and install the current file again.
- Nothing to install on iOS: open the site in Safari and add it to the home screen — that shortcut signs into the same account and the same games.
- Old build stuck on the phone: the home-screen shortcut always loads the current version, so use it while the app catches up.
App symptom, check, next step
| What you see | What to check | Next step |
|---|---|---|
| Install blocked on Android | Permission for installs from this source | Allow the source, then run the install again |
| App closes on launch | Cached data from the previous build | Clear the cache, reopen, reinstall if it repeats |
| Nothing to install on iOS | Whether you are looking in the store | Open the site in Safari and add it to the home screen |
| Screen looks out of date | Which build the icon opens | Use the home-screen shortcut for the current version |
