This topic has been discussed several times, however all the threads seem to be related to errors after the latest updates.
In my case, I have not installed any new software and my latest update was a few months ago, however my fingerprint scanner has suddenly disapperared.
The "Security" menue only shows PIN / Pattern / Swipe.
Besides this issue, the phone works perfectly.
I've done the usual restart / repair / restore to factory settings etc. but nothings worked. It's as if the phone never came with the fingerprint scanner option.
Your expert advice would be appreciated. Thanks
Hi @Xain, sorry to hear about your phone. 
Which country are you situated in, and where did you buy the device? Even if your country is not listed in the "Contact us" page on our website, you should still have a local team. If you tell me where you're from I'll look in to it for you and give you contact details. 
Hi Emir, thanks for reaching out.
The phone was a gift from some friends in the US, however I'm currently in Sri-Lanka.
Online customer care said I needed to send it to India !!:smileycry:
Trying to find a local solution
Try emailing [email protected] and explain your situation, hopefully they'll be able to assist you further. Since this is a global user based forum, I can't help you with a local case such as this. 
im having the same isues .there seems to be 2 types of homescreen with settings one is sony the other android is this messing things up im in the uk
Hi @willmc, sorry to hear that. 
I am not quite sure that I understand what you mean, do you experience that your fingerprint option disappeared in Settings > Security? To my knowledge, this should not be affected by the homescreen. Could you clarify what you mean and elaborate?
If you are missing the fingerprint manager, could you try to see if the previous suggestions in this thread help? Namely a software repair using Xperia Companion as a first step.
Please let me know how it went and keep me updated! 

The finger print scanner of my c5 premium is gone all over the power button not working at all. Just double tapping the screen is my solution in my phone. Can you give a support how to fix it.
Sorry, I had no luck with fixing my fingerprint issue. Like I said earlier, after being a die hard Sony fan for 2 decades, I gave up on them and never looked back since getting my hands on a One+
Good Luck
