My samsung a8 SM-A530F/DS is sometimes failed to response my input if my hands have any dirts of moisture... This is only happen to this device due to glass type, but in my samsung galaxy j7+ , even my hands is so moist or dirts, the touch still responding. Also my samsung a8 has no screen protector. So I have to ask this following that can help me resolve this issue

1. What kind of screen glass is built in this device?

2. Any recommendation to my fingers to reduce this issue? Than other device?

3. This device need screen/tempered glass to prevent this issue?

Have you tried registering your finger twice and see if this will help?

The OP is having an issue with the Touch screen, not the fingerprint sensor. And the Galaxy A8 (SM-A530F) has a fingerprint sensor in the back, not the screen.

B) Recommendation and quick ways on how to fix touchscreen issues.

If the Touch sensitivity setting is turned on when no protective film is used, the touchscreen may respond too sensitively and therefore malfunction. To disable the Touch sensitivity feature, navigate to Settings, tap Display, and then tap the switch next to Touch sensitivity to turn it off.

Certain factors may affect how well the touchscreen on your device performs. Please keep the following in mind when using the touchscreen:

  • If a third-party screen protector or accessory is attached, the touchscreen may not work properly. In particular, it may not work well if there is dust or air under the protector, if two or more protective films are attached to the screen, or if the protective film is peeling near the edge of the screen.
  • If the screen is wet, the touch sensor may not work properly. Even for waterproof models, some touch functions may not work if the product is used in water.
