Hello. I own a Huawei p10 and recently it fell out of my pocket and landed on its screen. Luckily it had its cover on and got a scratch on the upper left corner. Everything seems to be working fine until later on the day I noticed that the fingerprint sensor (glass) was unusually hot. I didn’t notice it before but are finger print sensors warm to touch? Also the finger print sensor is working fine, it responds as default and a also enrolled a new fingerprint ID just to see if it’s working, and it did. So anyone can tell me it will be okay or am I just worrying too much? Thanks
I say don’t worry. Others might disagree I know on iPhones the Fingerprint sensor is directly above the charging port so the charging port is overheating, In your case (I don’t know where the sensor is to be fair), try rebooting it, and see if no other component is causing the overheating. If it gets worse over time, replace the component that causes the overheating, or take it to a repair shop.
My phone also fell out of my poket and the screen was slightly cracked, fingerprint scanner didn’t work anymore but mostly, the area of the sensor got very hot. While the phone was still very much usable, except for the fingerprints, the battery life was very short due to the constant heating. It would not even last a day on a full charge while not being used much. I brought the phone to a repair center where they swapped the whole display assembly. (glass, LCD, fingerprint sensor) Now it works perfectly fine again and the battery life is also good (~2days). I hope this helps
