Confused here

[Standinnnn]

I have some problem 

1. I dropped my phone somehow and the screen was cracked and the touchscreen wont work on all of the section of my screen

2. Where can i find the Battert serial number and Charger serial number to filling up my warranty

3. Can my phone get repaired using warranty? if the warranty is unavailable, how much will it costs?

sorry for the bad english.

1.You can buy a USB OTG to unlock your device using a mouse and backup some of your stuff.

2&3.About the warranty,you should get in touch with xperia care:
