As we know and mention also the Galaxy A53 5G has an in-display fingerprint scanner and it doesn’t have a rear-mounted or side-mounted fingerprint scanner. And we all know that in-display fingerprint scanner is not as fast as they both.

So, that is another thing but if the screen of the phone is not clean and it receives more dust and oil then it will not work.

So, clean the screen or display with a cotton cloth and mostly the fingerprint scanner area. And try to keep your phone clean too. Not only the screen.

4. Remove and Re-register your Finger:

Occasionally, our fingerprint on the phone gets deleted or disabled because, for some reason, it may not function well, then this could be the reason behind the issue.

  • Open the Settings app on your phone

Having more fingerprints means having more processing and more caches. Having more fingerprints can also lead to this issue. If you have added the fingerprint of your family member then please remove them and add your thump only.

6. Remove Screen Guard:

A screen protector or screen guard keeps the display of your phone safe. But sometimes it also creates many problems and the fingerprint issue is one of them.
