I was at Sim Lim Square yesterday, confirmed that Orient Electronics (4th floor phone accessories shop) and at least one of the Burlington Square mobile shops have Xperia 1 V screen protectors or case too
I got a simple tempered glass from Orient Electronics to tong first, will most probably find time this weekend or next to get case elsewhere since so far I still prefer that textured grippy feel of the official stand/case
For camera protector, best to still buy from Mobilelite it seems, will have to check with them
