It was shown to you at the time of Mate 8 purchase, because it had 6 inch display too, but that time it was ~45.
Its ~38-40 now, but its a midranger. At singapore plaza, i heard via OPPO source there is some grand promotion of OPPO going on, in which some lucky draw or stuff. Lol.
You either get a KFC voucher, OPPO outdated Joy 3, Joy plus or 70cc bike (5% chance). One of them guaranteed. Lol
Nope its a midranger, you can get used latest flagships S6, S6 edge, P9, *6P etc in similar price too, with accidental warranty. I like Color OS though.
3-4 gb ram makes no noticeable difference, because it improves multitasking betwen more than 30 apps (practically impossible), because a normal non power user in real life multitasks between 10-15 daily usage apps at max.
G4 is much better than this overall tbh.
