If the app crashes, freezes, shows a blank screen after the logo, or hangs on a loading/"Securing" screen, work through these device-level steps — this is a different problem from login-link issues, and browser/link fixes won't help.
- Update both your phone's OS and Sweat Wallet to the latest versions.
- Restart the phone.
- Clear the app cache (Android: Settings → Apps → Sweat Wallet → Storage → Clear cache).
- Make sure the phone has at least 500 MB of free storage.
- Disable Battery Saver / Low Power mode and battery optimization for Sweat Wallet.
- As a last resort, reinstall the app — but only after confirming you can log back in: you need your newest "SWEAT wallet backup code" email, your 12-word secret phrase, or a linked Apple/Google login. Your funds are safe on-chain either way, but without a login method a reinstall locks you out.
Still crashing?
Some crashes are device-specific bugs on our side. Contact support with: your device model, OS version, app version, and exactly which screen it dies on (blank/white/black screen, spinner, or the logo flash). Those four details are what lets engineering reproduce and fix it.
