got mine via UPC contract renewal (original contract was made via digitec)
well .... some retailer got it for 449chf UPC had it for 399chf since mid april ...
after 4 month with it, i can't fault it... smooth good battery life excellent build quality 448chf with a 256gb U3 uSD card gorgeous screen (in house from TCL who is a reputable brand on the level, with ease, of the like from LG or Samsung)
hard to think it's a sub 500chf handset if it were not for the Snapdragon 675 and the 60hz screen (well ... 60hz is well enough for most)
Pro
price (4 month ago it was already 399chf via UPC ;p )
correct specification for normal to heavy day to day use
gorgeous curved AMOLED screen and not one from LG or Samsung
excellent build quality, worth of those 1200chf+ "flagship"
excellent camera performance (and NO bump)
gorgeous back and not a fingerprint magnet
128gb base storage just add a 49chf 256gb U3 card: 384gb for less than 450chf? can't fault that one
the case include in the package is quite good for a freebie
the Snapdragon being "only" a 675 you do not feel it at all (even compared to a Kirin980/Snap855)
the screen is "only" a 60hz FHD+ although feel snappy and smooth as if it was not "only"
in screen fingerprint ID is fast enough
Contra
a few softwares hiccup but some got corrected recently via updates
the smartkey on the left gone from a customizable key to a useless "activate google assistant only"
