My 18 month fingerprint reader seems died on me on my X 1 IV...

Smart lock is a non existent thing in my phone so no the solution doesnt work. Not the restart either...It worked a month ago about 3 times to do the restart then after that... nothing... Not the restart in safemode either...

Fingerprint test says -> It cant be read and the registering  cancel due some "time limit has  achieved" in an half milisecond...

Just send to an servicepoint for replace of hardware???

I got grey hair for these kinds of error and YES im into all forums and Reddit...
