Currently will be, LG G Flex 2
<S$500 local warranty (big price drop in 6months). Of cos there're those previous flagships running SD800/801 the Xiaomi Note, LG G3, etc. Older models doesn't mean they aren't good anymore. Just that people likes to have new things.
LG G Flex 2 had multiple updates over the past 6months, from overheating and throttling issues to currently running stable at acceptable temperature
Of cos can pick bones, but any phone has it's weakness including C5 ultra
BTW I'm not saying the C5 ultra is a bad phone but just not worth $500+ for what's it's offering.
1. The camera had been said to be average.
2. The chipset are used on <$200 range phone like Meizu m1 note and Lenovo K3 note. Even with Sony branding asking for more than x2 that of similar performance is it really worth it?
3. Nevermind the 2GB RAM but at $500+ you get a 16GB storage
But as usual most non-apple/samsung phones prices drop fast, so after a month or 2 the price will settle to be its real price.
