I am not able to open the screen of my phone (samsung galaxy a15) with my fingerprint, I went in settings and tapped the side button a couple of times for the phone to recognize my fingerprint, but when i try to open my phone by pressing my tumb on the screen, its not working help me
The Galaxy A15 doesn’t have an in-screen fingerprint sensor, so pressing your thumb on the display won’t unlock it. The fingerprint reader is actually built into the side key (power button).
Here’s what you can try:
1. Check fingerprint unlock settings: Go to Settings → Security and privacy → Biometrics → Fingerprints. Enter your PIN/Pattern/Password. Make sure Fingerprint unlock is turned ON.
2. Re-register your fingerprint: In the Fingerprints menu, delete your saved fingerprints. Tap Add fingerprint and place your thumb on the side key sensor, adjusting the angle each time so it captures the full print. For better accuracy, you can register the same finger twice.
3. Unlock the right way: Press the side key to wake the phone. Place your registered finger flat on the side key not the screen and hold until it unlocks.
If it still doesn’t work after re-adding, make sure the side button is clean, your finger is dry, and your phone is up to date.
