Work out whether it is the client or the account
The test is simple: sign in from another device or the web. If the account opens fine, the problem is the client.
Once you know it is the client, you can safely clear data or reinstall without worrying about the account.
What to prepare before you start
These five things cover almost every delay people run into: Confirm your second factor works, since a reinstall may require it.
Note the current app version and phone OS version. Have a stable network available for testing.
If reinstalling, make sure you remember your login password.
Six self-checks in order
Start with the simplest step: Force close the app and reopen to rule out a one-off process fault.
Restart the phone, which clears many temporary resource conflicts. Switch networks between Wi-Fi and cellular to rule out connectivity.
Check for a new version and update to the latest official build. Clear the cache in app management, taking care not to wipe anything needed besides login state.
If it still fails, reinstall from the official channel and sign in again.
Fees, limits and processing times
Numbers change from time to time, always confirm on the official fee page before you commit size: The help centre and in-app support cover most issues; for fund-related cases open a ticket and keep the reference number.
Nobody from real support will ask for your password, 2FA code or seed phrase - treat anyone who does as a scammer. Official entry: use okx.com or your own bookmark, and check the domain letter by letter - look-alike domains are the most common phishing trick here.
Install the app from App Store, Google Play or the official OKX download page; Android users should avoid APK files shared through chat groups. Spot, margin, perpetual and dated futures, plus options, sit at the core of the platform.
Strategy tools such as grid and DCA bots, copy trading, OKX Wallet with its DEX aggregator, and Earn products extend well beyond simple trading.
The OKX-specific part
OKX mirrors service status in the in-site message centre, so check there when several devices fail together. For one device, work through cache, network and version before resorting to a reinstall.
Frequently asked questions
Will reinstalling lose my assets
No. Balances are recorded server-side; reinstalling only affects the local client.
Do I need to redo verification after reinstalling
Usually not, though you may need to complete the second factor again.
Why is it stuck on the splash screen
Usually corrupted cache or an outdated build; clearing cache or updating normally fixes it.
