5th gen ipad hot home button
i have been using my iPad (5th Gen) for the last 2 years and it has the latest OS (v16.2). A couple of days ago when I unlocked the iPad it displayed a message "Unable to activate touch id for this iPad". Since then the home button is getting unusually hot, sometimes scary hot, when the iPad is in a locked state (even when it is not charging). The temperature goes back to normal when I start using it. Touch id is not working and I am not able to register any new fingerprint as well (shows a message it is unable register any new print). This did not happen before the recent OS upgrade. I have never used touch id. The article to which techs often point has no useful info. There is no Apple Store near me. Does anyone have any idea what maybe going wrong here? Thanks
