If you're having problems with the fingerprint scanner on your Samsung Galaxy M30, you can try the following steps to resolve the issue:
1. Clean the fingerprint scanner: Ensure that the fingerprint scanner is clean and free from any dirt or debris that may be interfering with its function. Use a soft cloth or tissue to gently wipe the scanner.
2. Delete and re-register your fingerprints: Try deleting your existing fingerprints and re-registering them. To do this, go to Settings > Biometrics and security > Fingerprints, and then select the fingerprint you want to delete. Follow the prompts to delete the fingerprint, and then re-register it.
3. Check for updates: Make sure that your Samsung Galaxy M30 is running on the latest software update. To check for updates, go to Settings > Software update > Download and install.
4. Restart your phone: Try restarting your phone and then check if the fingerprint scanner is working properly.
5. Reset your phone: If none of the above steps work, you can try resetting your phone to its factory settings. Before resetting your phone, make sure that you have backed up any important data.
If the problem persists even after trying these steps, it may be a hardware issue, and you should contact Samsung customer support or visit a Samsung service center to have it checked and repaired.
