My Xperia XZ premium (18 months old) recently had a software update and since then the fingerprint reader does not work and the phone keeps randomly rebooting. I am not 100% sure whether the issue is linked to the software update or if this is just coincidence. This normally happens after I either try to answer an incoming call or go to make a call. It is very annoying. I have tried a diffreent sim card in it and it is still doing the same thing. I have also tried a system restore from the system menu.
Try enter in safe mode and see any problem there.. a 3rd party app might causing this. If u know any recently installed call handling apps try uninstalling it. Uninstall Truecaller app too if u hav given permission to it. Update has no issues. Also power off the phone and wait some minutes before turning it on. Try resetting settings n reset options. If all else fails , back up everything and do factory reset.
Most probably reset settings solves it. Ensure battery has atleast 80% charge just in case something goes wrong and to have window to repair using Xperia companion.
