Galaxy A23 hot fingerprint sensor/power button

[NotMyPhone]

Since the update yesterday the fingerprint sensor doesn't work and gets really hot. The sensor wasn't even in use before. In the settings the sensor was not available to set up. I am still under warranty by the seller but hope that an update could solve it as I got the device for a really good price.

Hi @NotMyPhone 

Do first try > Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too. 

If this does nkt he'll then send some feedback via your Samsung Members App. 

A Samsung Service Centre can assess your phone if necessary. 

If I can be of any further help then please don't hesitate. Take care.  😎

Thank you for your help. Sadly nothing helped.

I also noticed that the fingerprint reader gets hot during startup of the phone and wont cool down as long as it is turned on. Save mode didnt help either.
