Uhh don't think that's how it works man haha. First, there's only a handful of Android devices that are more than RM2600, can count actually (Note 5, S6 Edge/+, can't  remember the rest that are more than RM2600). If it is more than 20, then i'll retract this statement. As for the depreciation, it clearly did not depreciate that fast. Look at the Note 3 and 4 when it came out. Even after a few months out it's still expensive. A new Note 4 now is still around RM1900-RM2000 which is clearly a RM300-RM400 depreciation after a year. Second hand also it still depreciate at a slow rate. If not, what you're saying now is i can buy a Sony Z3 at RM600 (first year RM1000 off, over a year another half more). You can search how much a Sony Z3 cost now which would clearly indicate that it depreciated at a slow rate (1800 after a year coming from RM2200).

What you may be referring to is the S6 Edge 32gb which costs RM3099. The market price for it now is RM2300-2400. In this case, then yes; it's the only phone for now that depreciated at a rapid pace. Maybe because the price was too high leading to low demand and ultimately low market value. So far this is the only Android phone that fits the description of a fast depreciating Android phone. As for the rest, i don't see any that faced a similar fate like the S6 Edge.

And we don't need to downplay Android as much; they've come a long way with a bunch of features and had the hold-for-options feature way before this 3D Touch thingy. Their features may not be flawless (laggy, sometimes not working, crash) but they still managed to realize the concept, which is a start.
