I got mine from Senheng too. I called senheng's customer service and they told me that if there are any problems to just bring it back to any senheng outlet.

But I did register my phone with the ewarranty by sending a email to ewarranty.sme@samsung.com

Information needed.
1. Purchase receipt (attach with email)
2. Full Name:
3. Mobile number :
4. Date of Purchase:
5. Model code:
6. IMEI number /Serial Number:
7. Email Address:

They were very prompt. Got the reply within 24hours.

Hope this helps.

There are 2 versions of case friendly screen protector for x-one sp. Version 1 only wraps until the side. Version 2 is the new and improved version that wraps til the back.
