The seller in Qoo10 is Empire. I have already emailed to the seller, waiting for seller's reply. Do u know whether I need to bring the physical phone down? Or I can ask someone to go down with my handphone IMEI nbr and Serial nbr? Thanks.Which seller you buy from?
From the previous discussion, malaysian set probably will be recognized by sg service center.
You can bring to the service center if really curious.
Btw, don't bother to send email to xm service center to check the warranty. They will answer it as don't know.

also like I said just buy usb-pd brick, better get the higher wattage one so next time can fast charge phone and charge laptop also. qc4 brick also very rare, even on taobao, but you can get one if you buy the mi wireless charging pad.
